The modification shown in this video was done on a w220 S-class mercedes.
In this video I show you how to repair your Mercedes key fob with a sheet of paper (card stock [less folds], bond stock, or regular printer paper will work)
Mercedes dealership quoted me $500 for a new copied key and also said that more than likely I would have to also change the ESV/ELV (key tumbler/ignition key lock) for an additional $800. Thats a total of $1,300.
Instead, using this method it may only cost you $0.01.
Yes that’s right only 1 cent.
And for those wondering, the check engine light seen at the end of the video was pertaining to a separate “bank 1, sense 1” issue. :) 😁 🤫
I hope this helps you all with this issue. - ยานยนต์และพาหนะ

I have had a very bad time of it. I will spare you the details but you saved my whole world world tonight. I couldn't afford to have it serviced right now. I prayed to God for help. Then I found your TH-cam! God helps those who don't give up. Thank you Sir!
Amen, and I am glad that this helped you.
God works in mysterious ways my friend🙏🏾.
Stay blessed, and I would love to hear that full story of how this helped you when you have the time.
@@majanboo22 All I can tell you is that it was a series of unfortunate events. We get on with it and push thru. Sometimes you feel like yiur faith is being tested...so you don't let go of God's hand, then Bam! Like magic, you're no longer up the creek without a paddle! You save folks a lot of money and stress in these times too. Incredible! Mind blown.🙂
2023 and you came in clutch thank you for this video
You are welcome.👍🏾
You’re a life saver… I called different auto mechanics but they couldn’t resolve this and when I did this it worked perfectly fine… thanks a lot I’m so much grateful.. I just subscribed to your channel.. thanks 🙏🏽🙏🏽
Wow. This really works. Thanks a million. FYI this technique will work with regular paper too. I was stuck in parking lot and I used a piece of paper from a bank receipt. I just folded it twice as many times to get it to right thickness. Worked on the first tried.
You are welcome, and great job! And thank you for reporting back that this also works with regular paper. I and I’m certain many others greatly appreciate your info.
All the best.
I’ve got the same problem with an E320 key- just like yours (2001). This just looks too crazy but I’m going to give it a go. By the way I love your music-it’s soothing for my worried mind and heart. Thank you sir!
Thank you for the kind words. I am glad you enjoy the music as well. 🙏🏾
I appreciate you bro. My daughter dropped my keys to both cars clk430 and my bmw in a bowl of water. The bmw key worked as soon as I dried it off but the Mercedes key wouldn't open the door or strat on e I got it open. I replaced the batteries and that let me unlock it. It still wouldn't start so I did what you did in the video I took the key apart and cleaned all the water marks off and placed the folded paper in the and put it back. I tried to start it again and it worked. 3 hours later I was finally able to move my car. Thanks bro that video saved me time and money. You the man👌🏾
You are more than welcome my friend. I’m glad that this video has helped you greatly.
I have the key fawb with the chrome sides and I tried this method using a folder piece of thin box material and it worked I was starting to think I would have to get another key fowb and this method saved me a few bucks thanks my good sir may gawd bless you!!!
You are welcome and God Bless you as well my friend.🙏🏾
And a special thank you for informing all of us that this also works with the mercedes keys with the chrome sides.👍🏾👍🏾
Is it difficult to dismantle the key fob? (Chrime side type)

Alan leon Hehe..That’s Awesome man. I’m glad this fix worked for you and you got your keys up and running. And much thanks for the subscription.
Thanks man and I have a lucky find for you. I changed the battery in the key fob and still the key would not turn. Also the trunk release inside the car would not open the trunk so I thought the car battery was dead. New keyfob battery but the door lock buttons would not unlock or lock the doors. I crawled into the trunk by pulling down the seats in the car. I thought maybe there's a latch in the trunk I can pull, but I hit the trunk button on the keyfob while I was in the trunk and everything works now. My mechanic said there is a sensor in the trunk and by getting closer to this sensor the keyfob with a new battery was able to reset. Everything works as normal with no error codes. Time for a quick "Italian Tuneup" up to Malibu on the PCH. Hope this helps!!!!!!!!
Thank you for posting this information. This will greatly help those who may have the same keyfob problem/issue you had.
Good job man. 👍🏾
Did this after my key fob went underwater! Cleaned everything with isopropyl alcohol. Did not need the paper wedge but the video helped me get it cleaned out. Working again! Thank you sir!!!
You are welcome.
I could literally kiss you😂 this happined to a customers car while I was doing a $75 service and I thought I was f***ked but I watched the video ripped a peace of paper and shoved it in there and away we went! Thank you so much.
You are more than welcome. I’m glad it saved you in emergency.
Thank you for your video I replace a battery shell of my remote even with the new did not work, but I used your paper trick man guess what my remote freaking works man dang I cant belive this. Thank you so much for your video....
You’re welcome.👍🏾
Thank you very much buddy, you save my weekend and alot of Euros 🙏🙏🙏🙏 it worked on my Mercedes Vito 2.2 year 2008
You are very welcome.
Well your paper trick worked! My girlfriend dropped the key fob in a puddle or something and it wouldn't turn over until i watched the video. Turns out the sensors were not lining up.
Thank you so much for this video...your tip is awesome
Works like a charm
I am glad it worked out.👍🏾👍🏾
Thank you so much!You are amazing🙏🙌

OMG! It worked!!! I spent $800 for new starter which worked for a week and quit on me again. Bought a $12 fob on Amazon and the damn car started right up like nothing was wrong. Dealership quoted me $1,500 for the same job I just did. Thank you so much!!!
You are welcome. Anytime.
Did you have to reprogram thr fob?
No, it should start right up

No problem, anytime.👍🏾 🇳🇬
This works! Just tried it! Car wouldn’t start after trying this hack it started right up
Congratulations and well done!👏🏾👏🏾👍🏾
Thanks for the video! I have the newer style key, with the chrome sides. Going off your solution, I opened up the key by sliding off the two chrome pieces and cutting through the glue joining the plastic, and put a rolled-up piece of paper above the IR sensor (little rectangle right above the panic button) to keep it pushed down. Seems to have happened from the key being dropped one too many times. 20 minutes saved me 400 bucks!
Derek Singh You are welcome, and thanks for this extra method to fix the IR key fob. I myself also upgraded from my old black plastic key fob style shown in the video, to your chrome side key style as well. This is good information to know.
I now keep the black original key fob as a backup.
Thanks bro for valuable tips
Balwinder Sidhu you are more than welcome man. Anytime.
I had this issue in February whilst I was at work trying to go home 😠. Quickest solution I found was disconnect the negative side of the battery leave for a few minutes reconnected the negative battery terminal & it worked straight away and touch wood it's not happened again.
The car battery ?
You are the truth, thank you it worked out great 👍
Thank you and you are welcome my friend. Well done👍🏾.
That it is Amazing work!
Its work! Thank you!
Thank for the compliment and Congratulations on getting your keys/car up working again.

Thx you so much it work, I was stuck for hours an saw this video, thx you
I am glad you were able to get your car started. You are welcome.
U really helped me thanks 🤙🏽🤙🏽
You are welcome man.👍🏾
Thank you for the video on how to take apart and assemble. My wife washed my fob in the washing machine and it quit working. I followed this to take it apart at used 91% isopropyl alcohol with cotton swabs to clean it the chip and contact points. Was very dirty and watery. Luckily the fob came back to life and I can start my car again! The unlock and lock buttons do not work however
Awesome, I an glad that you can get the car started.
Had similar experience, just to add to what you just described, apart from cleaning the contact point, make sure u clean the battery also(try not to touch them) when putting them back in and make the latches firm enough. My unlock button dint work after the first try. I took everything apart and observed that while removing the battery, i had expanded the metal brace that held them together. I adjusted them and voila! Everything worked perfectly.

Excellent, I am happy that it worked for you! Good job!
I’m having the same issue did you Mercedes not start ? Or was the key not turning in the ignition ?
OMG! Thank you so much for your video! It might take a few tries but it eventually works. How long can I expect for this to work? I wonder how big of hurry I should be in to get to the dealership for the replacement. Thanks again!!
You are welcome. I already made a new key copy(2nd key), but this fix is still working with the original.
Hey man I had the same problem in my 2004 c240 but I realized after doing all that one of the infrared eyes was disconnected from the circuit board on the one side so it was lopsided a bit to get that fixed and got him to soldered back together check all the connections all those little eyes if they're sitting right on your circuit board and the repair cost me $5
This is great news and thank you for posting this info here… I am certain this will help those in need who may have the same issue.

Oh you hae that type of key with a red disc on it! So beautiful. Only me i got the ugliest key ever. Doesn't have either a sepparate button for the back, only lock and unlock doors. (Well maybe becuase is T Modell) however I don
t have that cool red button or whatever it is.
Neptune Vibe the red button is panic mode.
It is to be used to cause the alarm to start making noise in various emergency situations. And attract he attention of people around you.
For example if you are being robbed.
I'm kinda blown away by this fix!! How'd u ever find this out?? I know Mercedes n most of these issues r EIS unit behind key fob. Around $300 to fix
As an electrical engineer, when I looked at the key fob, I knew it utilized an infrared sensor.
When I had the non-start issue, I immediately thought of “the average tv remote, not being directly pointed at the tv, and thus not being able to change the channel”.
Thats how I realized, the key fob was not aligned due to the old worn out plastic housing.
Is it because of the broken tab that you need to "wedge" it?
Great ideas
Thank you.🙏🏾
Thanks a lot look like is going to help me. I'm experiencing my Vito won't start
Luis Lango You are welcome. I hope everything works out.
Nice one !

i have a 2004 w230 sl350 with the older key. does this work on that as well?
Great trick and thank you for sharing
If your key fob looks similar to this style era of key fob in the video, It should.
I dont see why not. After some time, the plastic wears and slightly deforms. Then the IR laser/light does not line up with the Cars tumbler.
what yr and model mercedes is this?

Is there a way to reprogram my second key to be recognised by immobilizer? Key was working fine but i tried to take radio out by bit of force and the key stopped working. I have other key that only locks car manualy. And the button on starting key doesnt work.
Possibly, but you need the $500 CGDI Mercedes key programmer tool/software(red plastic tool in the background of this video), and know the step by step process on how to do it… I have done it, but it’s a 15-20 step process if I remember correctly.
In my opinion, you are better off just paying the~$300+ for a new programmed key copy(from a NON-Dealership).
@@majanboo22 what if i remove immobilezer
@@lauris4887 I am not sure.
How did you figure out that wedged paper would line those two up, that is amazing. BTW, a folded business card keeps my glove box closed on my 1998 E320.
cc92103 Thanks.
When I had the issue of the key not turning all the way, one day I thought “the plastic key case is worn and possibly loose so the infrared emitters from the key must not be aligned”.
I tried turning the key while applying force at different portions of the plastic key shell and when I eventually squeezed on the worn plastic key case, the key turned immediately in the vehicles “ELV” (ignition tumbler) and the car started right up. I knew then that my issue was either the worn case allowing the key’s infrared led emitter to be off center alignment, or that there was a circuit component on the key’s circuit that was no longer making electrical contact with the key’s circuitry.
And thank you for the folded business card tip glove box tip. This may come in handy for I and other readers in the future.
There are only 2 screws that hold the handle on to your glove box on the inside of it, try replacing them because they seem to work themselves slack thru wear and use. Good luck!!
amazing..... Thank you so much bro broooo !!!

On my 05' SL500 I can enter the vehicle by the manual key and start it but, can't open and close the doors or trunk via the remote. Dash lights and door bell does not work? tried charging both batteries but the trunk battery doesn't seem to take the charge. Any suggestions or recommendations?
Anton For the issues you list, I do no’t have any direct suggestions other than to google the mercedes forum “MBworld.com” and search through the SL500 forums for this particular issue.
I have not come across this specific problem on my vehicle, and hence I have not had a reason to look for a solution.

Nice video. However, both my key fobs didn’t turn. One I use all the time and the other was a spare. Also, no interior lights came on when I opened the door. I thought battery died but it didn’t take a jump either. Any ideas or suggestions?
J will I can’t say as I have never had this issue. I would recommend googling the term (auto forum) “MBworld keys will not turn Mercedes ____(insert model here)___” and see what mbworld members have posted with the same issue.
@@majanboo22 It was the main battery. It’s an ‘05 that I’ve owned for 8 years. I think it’s OEM battery too. I’m replacing it myself. Any pointers?
J will is it S55? If so, I’d just remove all of my stuff out of the trunk and disconnect the negative terminal of the battery first.
Then after, I disconnect the positive terminal of the battery.
I Always do it this way with cars, because the negative battery terminal is grounded into the cars Chassis/body.
Imagine if the negative terminal is still connected, and you are removing the positive terminal first, and as you are un-tightening the positive battery nut and you mistakenly make contact with the chassis...a nice big arc/spark will occur.
Keep in mind this can damage sensitive sensors as well. So to avoid this, disconnect the negative terminal first always.
Sorry to be so long winded.
Thank You

Cool vid my key red light doesn't flash when I press on my lock button, so I can't lock my car from the key fob, just unlock it ! ESP it's showing up on the screen 2001 E430 ! will this procedure work,I don't have the original key fob ,I have transfer it to an upgraded metal key fob ! but it has been like this since I purchase the car,there is a bunch of functions that doesn't work,sunroof,radio, little controls,windows and rear view mirrors are all crazy !
Technics Melancholic I think your original key fob for your year/era mercedes may have been the all black plastic key.
Your new metal key has a different style of case and I DO NOT think this will work for you.
Unfortunately, you may want to have your key circuit board/components looked at by an electrical tech who specializes with keys before paying for a brand new dealer key and labor copy service.
@@majanboo22 Thanks for replying bud,it looks exactly as the Original it's just an upgrade that has metal in it ,the sides are made of metal and it fully opens for easy replacement ! but it follows the same pattern as the Original same composition same buttons placement etc ! it did the same with the Original key fob ! I had to replaced because it was all torn apart ! and wore out ! but it's looks just the same with the MB logo placed on the back not on the center !
@@majanboo22 Will do bud Thanks !
I’m going through this issue now. Mercedes sucks for this
Could i possibly have the same people? My Vito 115 CDI used to start very well, until i had my gearbox replaced with a second hand one. After inserting the second hand gearbox, the key would not turn in the ignition at all. However, my EIS and smart Key were tested and said they are all good. When connecting the battery, the ABS automatically runs on its own and the rear fan kicks as well. At this point, seems like i am running out of solutions of what i can do to fix it. Please advice me on what could be the problem, could it be the key? And i have to do what you did in this video? Or?
Sifiso Dlozi I am not sure what the issue with your car is. And I don’t believe this video will help you.
I have heard on some of the more recent mercedes when the transmission is changed, and another transmission is installed, there is a “provisioning / transmission computer registration” process where the car/transmission may need to be connected by computer to the mercedes online “registration” servers so that it may function correctly after being installed.
I am not sure...maybe this is your issue.
I have never seen a Vito 115 CDI, as they are not sold in my country.
@@majanboo22 i forgot to mention that my gearbox is a manual gearbox. I think i will have to call in a specialist then in my case. Thank you very much for your advice and knowledge.
Sifiso Dlozi you are welcome.
I have same problem with w203 ,oneside of remote is not turning but another side is turning but not engine start,,,after 3 or 4 trys it's start. What I do 🥺? Plz help me
I am hoping the instructions shown in this video can help you. Otherwise, I am not sure.
Do you knkw the fix for key not unlocking or locking the car from a distance or anything anymore
Yo may need to tattle your key fob to a circuit repair shop. I have heard of this before (I think it may be in the comments of this video) and someone said that a small circuit component separated on their keys circuit board.
The circuit repair shop was able to see it and solder/fix it back to the circuit board to make the electrical connection.
@@majanboo22 thanks for your comment man, but it seems my key works fine but there isn't a radio connection
@@olivermateee547 yes if a capacitor or other circuitboard element has disconnected, radio transmission portion of your key fob may not work as best as possible.
My car is doing the same not closing windows , only sucking the key 🔑 and not turning I'm sure this might work w210 e230 parked for 6 months now
Give this a try and let us know how it worked for you.
Do you mean that paper piece, you've put in,, acts as battery??? :) what a clever man..!!! :) )))))))))))))
The battery in the key fob is never needed to start the car using the key in the ignition switch.
Need to welding the UR on the 🔙 and that's it.
I don’t think the IR led on the key Fob is desoldered from the circuit board. It just was not aligned with the EIS key “Tumbler” in the steering wheel
Broken key how to start 1998 Merc ml 320. Any ideas.
If the key is literally broken (as in electrical circuit componnent...capacitor, resistor, etc) broke off, you may want to google or read through the comments (someone posted about a year ago) of an actual electrical circuit tech repair shop for the key. Take all plthe pieces that fell off to the tech and have him solder back on.
If key is physically broken into several pieces, you are better off purchasing another key and having it programmed to your car. This is possible, but the specialist doing it will need the mercedes CGDI key programmer equipment.
If you are not tech savy, find a specialist or someone to do it for you. They may charge youa around $350 USD (at best) to $400...It won’t be cheap, but usually will be cheaper than the dealership (dealership may want you to buy a whole new key and electrical lock tumbler set and install in your steering wheel....very expensive at mercedes.
My ignition key turns but won't crank. Could this fix the issue??
No i dont think so.
Mercedes Benz officially hate you 😂😂😂
😂Hehe..well as long as it helps people, I don’t mind.
I don’t know how often this needs to be said. The batteries in the key fob play NO part in allowing the key to be turned or in starting the car. The fob is instead powered after insertion by an induction coil surrounding the key. The fob batteries are used only for locking and unlocking the car remotely. This is why you can use the emergency metal key to unlock the car and the key fob to then start the car even if there are no batteries in the fob.
I expect the problem in this case is a dry joint in the soldering and stressing the board with the paper wedge makes the connection. I don’t think it has anything to do with the optical alignment of the IR transmitter and receiver.
Thank you for explaining the batteries in the key have nothing to do with starting the car.
Also, you may be right in the fact that there was a dry solder joint as well. In any case, the beauty of this is that you can fix your mercedes key fob with a piece of paper.
This is An issue where if you went to a mercedes dealer to fix, you would be shelling out a substantial amount if money (~$500 to $1,000+ USD) to resolve.
Thank you for your observations.
I really don’t understand your motivation for posting this nonsense video. It has no sound engineering basis and it’s ridiculous to pretend that stuffing a piece of paper into the key will fix all problems. It just happens to in this case. Far better to send the key off to someone who has some real talent and experience who can look closely at the soldered connections and make the necessary repairs. Take a look at the videos by NorthridgeFix. There’s a guy who understands what he’s doing and brings the tools and experience to the job to complete it successfully. .
Mark Norton Ok, not everyone at any exact given point and time has the immediate ability to just send off keys to be copied, and go without their vehicle for however long it takes to
1) have an electrical specialist get to their key in the order it was received.
2) or leave their car wherever it may be stranded (as they have already known their key case is faulty, but have been dealing with it for quite some as they do not posses the $500 to just give to the mercedes stealership who rips them off making an ~$15 (near true circuitry value) key copy.
3) need their vehicle up and running immediately as they may have work the next day or in the next few hours, and can’t afford to pay for and maintain the cost of a rental car for up to 2 weeks in order to send off the keys (as you so geniusly recommend) to a specialist who will need time to diagnose, and then send you the invoice for repair and await your approval to begin.
I could go on listing more reasons, but I won’t.
If you don’t like the vid, you can easily keep it moving to another youtube page.
But there are quite a few people this has helped. Judging by the comments and quite possibly the thumbs up.
No worries nor sweat of my back, have a good one.
Mark Norton Also forgot to mention...my youtube page focus is designed to aid those in finding simple and frugal ways to solve their problems.
If I went into full scale engineering circuit analysis of this issue (Kirchoff’s Voltage Law and Kirchoff’s Current laws, transistor saturation points, etc), 99% of the viewing audience would be lost in the first 20 seconds.
Mark Norton Hello. My key just worked last night and I just went out to start my car and it won’t turn in the ignition or unlock/lock the doors. Any ideas?

Can you turn the key turn all the way to the “engine start position”..(2nd position)?
@@majanboo22 Yes. Everything works as it did before. When I insert my key the zip noise is made which I’m guessing Is the ESL unlocking. Position 1 works as normal… some lights come on and begin to work as normal. When I turn to position 2 my instrument cluster and all of the lights on the gauge clusters power on. When I go to do the flick motion to turn on the engine nothing at all (no crank, no noise, minimal clicks sometimes it’ll click once or not at all) I’m thinking it’s either my ignition switch bad, my key went bad or my EIS(Ignition Switch) went bad. I am not sure how to diagnose if the EIS went bad as a lot of videos show the cluster not turning on when the key is inserted or they can’t turn the key past position 0, and it the steering wheel doesn’t free up
@@majanboo22 My steering wheel opens up fully and my power supply for interior and exterior is all fine. I’m thinking my starter possibly went out as it was all of a sudden. I went to get gas drive home came back out within 30 minutes and the car won’t crank
@@BMJJ8 yes, it may be your starter.
i have the same problem with a mercedes e220 cdi since 2000 ..
Hopefully this fix will work for you. Let us know.👍🏾
Card stock paper
Yes, it is considered entry thickness Card Stock. But there are others who have commented successfully using/folding a thin bank receipt (they were stranded) to get their mercedes started.
Oh, by the way, had to replace batteries in my fob. It takes two 2025 dime/size batteries for 13.00$.

Thank your for this info. Much appreciated.
@@majanboo22: Thing is, these are extremely sensitive fobs! You can't just throw them around for heavens sakes! Like your gal, tender and sweet.
@@jamescosby2343 HAHA! Lol. So true.
After changing the batteries I was still having problems starting the car. I opened it back up and bent the metal that goes around the batteries inward so that it makes a better connection to the batteries. It started up right away with no problem after that but then it had some problems again. I discovered that pinching the fob so that the batteries make a connection while turning the key is the answer and it starts right away.
sketchyj great find, and I appreciate you posting this info here for others as well.
The battery is absolutely not responsible for starting the car. It is only for opening and closing. Car even should start without battery.
I tried this but it didn’t work. The infrared light isn’t coming on but it was just working last week. I bought a new key fob and switched out the motherboard but now I can’t start my car
Mario Estrada I would suggest placing your original keys motherboard back into its old case, so that you can at least be able to start your car(hopefully).
I have seen and read in research online that there is a electrical part on the circuit motherboard that breaks (i think electrical wire lead for Infrared LED) or comes off. This part can be re-soldered to fix the key.

Check out this guys youtube video. I initially thought this was the problem for my broken key, but it wasn’t.

I watched this video but I don’t know how to do what he did. I did put it back in the old remote but couldn’t get it to turn on my car so now I don’t know what to do. I’m not sure if any locksmith could even help me
Mario Estrada upon switching it out into a different case, you may have damaged a circuit trace lead. I have some extra Mercedes blank key FOBs (made in china). I can send you one but, you will need to find someone in your area you can give your broken key to have it re-soldered/fixed. And then they can copy your key’s code data to the blank I send you (using CDGI).
Or
they have the CDGI Mercedes tool kit and laptop/with software to plug directly into your cars OBDII port and to reprogram a new key for you from inside your car.
I have the CDGI kit and software but I don’t know what city/state you are in.
Waldemar Fechel’s youtube page is really good on how to reprogram keys, ecu’s etc formercedes, bmw, toyotas, and many other vehicles. But you need to have the tools.
