Thanks a million!! My FOB for my 2005 SL 55 AMG wasn't working and I thought I had to go to the dealer and pay whatever they were going to charge to correct it. Luckily, I watched your video! I put the FOB in the ignition for a few seconds, took it out, then pressed and held the Unlock and Lock buttons together for 10 sec then pressed the Lock button 5 times and it worked! Much appreciated.
All I want to say is THANK YOU. This video saved me perhaps few hundred $ as I was never able to get a straight answer from either the dealer or any other local automotive locksmiths (the dealer wanted me to buy a new key). So one pair of my 2008 ML320 CDI key had stopped working (will not unlock nor will start the car) about 3 years back and since this is mostly a in-town car, I kept using the other working pair, until today. I followed the steps outlined in the video and found out that the 'broken' key had both the LED and the infrared sensor operational and they worked exactly as shown here. Next all I did was put the key in the ignition and within few seconds the car display showed "Key check-in in progress, please wait" message (Btw I didn't press both lock + unlock buttons prior to inserting the key in the ignition). Within seconds my 'inoperable' key came to life and now once again I have a working pair. Btw, I didn't have to change any fuse as one key was always operational. Thank you again and keep these great videos coming. God bless
4 years later and you're still saving our butts! Thank you for the video. The recalibration was perfect. Put the FOB in the ignition for a few seconds, then press and hold the Unlock and Lock button for 10 sec then press (in my case a 2000 E320) the Lock button 5 times and it worked! The flashers flashed a few times and it was recalibrated. One little thing, when I opened the door with the key, the alarm went off. I put the FOB in the ignition and it went off. Thanks again!!!
Wow! Thanks! My fob has been inoperable for 2 years. Changed the battery initially and that did nothing. I modified your instructions a bit. I actually started the engine with the inoperable fob rather than just putting the key in the ignition. I turned the car off and held the open and close buttons down on the fob simultaneously for 10 seconds. When I released, the car made 2 clicking sounds and the fob is now working.
Thank you - this was extremely helpful! I didn't realize you could check the Infrared signal using your phone camera either - that is an extremely useful trick for all IR remotes!!!
You just saved me a whole load and from being skinned alive by Mercedes, I have tried to resolve this problem for a whole year and multiple official dealers and key specilaists, yet by spending a few minutes watching this clip, I solved the problem by re syncing the key of my 2011 SLS GW. Thank you!!!
Thanks for the info. The infra red trick with the camera has saved me checking the rest of the car for my unlock issue. I now know that it is my key fob that has a fault. Brilliant.
Thank you so much for this video!!! Dropped my key in a little bit of water. Took the key apart and let it sit in white rice for hours.My car wouldn’t start but the doors unlocked. I watched this video and found out It was just a fuse!! Save me hundreds of dollars!!! Thank you! I just subscribed!!
Thank you, thank you, thank you 😊 I feel so knowledgeable now about my car ❤ I know now why my doors wouldn’t lock, dead batteries, no red light no infrared. You saved me money 👍 I thought I had to buy replacement keys.
you dodged a bullet! i am in the same predicament now! now red light no infared! key works to start car but not to lock doors /unlock after installing new 2025 batteries
Hello Mr.iRepair! Thank you so much for this simple straight forward information! Trying to figure out how to fix the lock system on my Dad's ML350! and it worked!
Wow 🤩 u r my Hero!! My Merc dealer in Anchorage wanted $1100.00 (totally outrageous) ridiculous! I can’t believe it worked and my husband thinks I’m a genius!!
Thank you for this...a little update. If you try the "both button hold down & 5 press on the unlock " it will reprogrammed the key..BUT...you have to put the key into the ignition and the dash will say " re-calculating" The dash will return to normal after completing and its all good from then on
This is a great troubleshooting vid. Question is, if any of the early steps is true, how to proceed? In my case the buttons work only intermittently, so there is sometimes, but mostly not, an LED and an IR. Can the buttons themselves be repaired? I just bought this 2003 E320, it looks like the (only) fob was run over 😢
Hey Keith hope all is well? You'd mention in this video that the key fobs work off the antenna are you saying they work off the radio antenna module located inside the back tailgate?
Helped me with my 2009 B class, but the fuses are not in the back. Couldn't find the fuse, but fixed my key and later linked it with the car. Saved me 200 bucks
The only thing the batteries work is the lock/unlock/truck release. Anyway. What starts the car is when you insert your fob in the slot to start it you hear the steering wheel unlock. What that is is the EIS. It is magnetized and inside your fob at the end on the circuit board near the infrared light on one side is a copper coil which gets energized and that makes the 2 infrared boxes light up (you see it as one light on the outside via the camera as you showed) and sends info to the car verifying it’s the correct key and it unlocks the steering wheel allowing you to start you car. Part of Mercedes anti thief feature. Now my car won’t start because this copper coil is broken off on one end. I’m in process of repairing it. I’m just waiting on my solder kit to arrive via Amazon. And I’ll reattach it and hopefully it will work. Or else I have to get a new coil they sell on eBay
Hello my friend. I just wanted to thank you for sharing your knowledge. My issue seems to be with the infrared signal. Would have never thought to check that. Many thanks again. Tom
@@anwarvarghese5730 so what happened did we get an answer boyz??!! im in the same boat how we going to fix this damn infared problem! man! niiu im broke!! 😂
this is the perfect fix for me, i swapped the computer battery in my 2007 s550 and didnt know i had to resync my keys, thanks for the help. wish i knew this before i spent money on new key batteries.
Hello I just bought myself a 2005 CLK 500 and I've been having an issue where my key sometimes will not turn so I'm in the process of cleaning the fob itself could this possibly cause the main electrical to turn off while driving and this includes the instrument cluster environment control and radio everything quits but my windows. Also oddly enough the car continues to run I have power brakes power steering and the windows of course that's it thank you.
So for me on my 2012 ml350 the lock button on the key fob isn’t working. I see the tiny red flash light is not coming either when I press the button. All other buttons work. Does this mean that the fob has gone bad because it isn;t transmitting the infra red light?
Hello, hopefully you’ll be able to help me and respond ,also thank you much for putting out the videos, I have a SLK320 2004, I’ve recently bought the car, there are a few bugs that I am trying to get out. One of them is the key fob, I have replaced the batteries and they are positioned properly. The lights work on it, I’ve checked the fuses in the areas of the engine compartment, the left/Right sides, also next to the steering wheel, there was a diagram that said there were fuses on the passenger side right next to the globe Department did not find that, did not find any fuses in the trunk, if I saw correctly, the antenna for the fob is in the trunk did not look at that yetif all of the wires are connected to it, what else should I look at?
10:45pm est. Good evening Sir. First let me say thank you for the videos you put out, you’ve helped me with multiple issues over the last couple years. I’m just wondering if you’ve worked on this issue with a laster model ML 315 as my 2015. I’m having the same issue and I’ve tried everything in this video.(except having the module scanned) Also there’s not a fuse box in the rear anymore. I’ve checked the other three fuse boxes, but not sure which fuse it would be in those. Besides scanning the module is there anything else you can suggest? Thank you in advance for any help you might provide! God bless!
Check the fuse first, if it is ok it SHOULD show some i signs of life by locking / unlocking the car. i was playing around with this thinking why it is not working and what are my next steps without checking main step - FUSE.
I have so many issues with my 2007 ml 320 Mercedes. Because previous owner messed up electric system.. my speedometer doesn't work engine light on always. It's a mess now she's not shifting properly
My c230 won't go over 20mph I'm told it will be about 2200usd to replace trans computer or whole trans is there anything else that could be the problem before I pay that cost
I have a 2002 C32 and chrome key stopped working after it slipped out my hand and hit the floor. I have 2 other keys so it’s now I’d like to figure why it don’t work out of my 3 keys 2 don’t turn car on I put it in ignition and it won’t turn.
My key fob is not working, only the locking is not working! Have changed the batteriy many times, and the key fob did work on and off before i changed need help!😩 Do i need i brand new key fob or what?🤦
Can anti theft system can be triggered by trying to remove radio without tools, now my car wont keep running for more than half second. How do i fix that?
Thanks for the video. Great. I have a 2016 Gle 400 and the display comes up with fob not found. Battery is good but can’t see the infrared. The second key works fine. Did you thinks it’s the fob itself? Many thanks
Hello. Mercedes Bclass 2010. Are you still giving advice. My fob is ok as far as battery is concerned. I opened drivers door with the key. I reset the ?AAM by pressing the buttons as shown and still by inserting fob car is dead. What next? PLEASSSS
Hi so my problem is with my 06 cls500 key fob was working just fine sat the car down for a week go to unlock it an nothing changed the battery in the remote I can see the red led light up when I'm pressing the lock/unlock trunk release buttons but checked the Infrared signal with a camera an nothing,, is the remote junk can it be fixed? It does look like a aftermarket remote i believe
I have a e350 2011 I changed fuses and put new battery do u have a answer on how to fix it only locks wen I get out and close tha door if I'm outside and press locks it won't open
What if it says " key does not belong to vehicle" . No locking or unlocking and it won't start because it's not recognized. Batteries in fob are new and infrared works. Glk 350 is vehicle
Hi @iRepair autos, I use a GL 450 2007 . My key won’t turn the ignition, it won’t work on the doors either. If i remove the battery for a while it allows the key. But once u switch off the dashboard lights stays one like you wanted to start ignition. One time the car started but it wont go into gear…. And after switching it off with the key it wont off ….. i had to remove the battery for it to turn off
Good evening.. I have a 2005 model W169 A170 and everything works, but my steering doesn't unlock, therefore I can not start my car, because the steering is locked.. I need help please, which fuse do I replace because my fuse box is located under my feet, driver's side, (RHD)
Great video. My key fob red light works most of the time when I push the unlock button and the infrared works as well. However, neither lights work when I use the lock button. Twice in the last three weeks, I had to press the unlock button many times to get it to open. Any ideas would greatly be appreciated.
The car "picks" up the signal when you press the lock or unlock buttons, as there is a small buzzing noise that lasts for approximately 5 seconds. Although, the doors do not lock nor unlock with the fob. I can still unlock and lock it via the Mercedes me app. Help?
Got a w210 e320cdi estate 2000 plate been fine. Parked up but had to move. Fob wont open or close doors Key wont unlock steering so can't start. Fob key flashes red. What can I do?
I have an SLK from 2006, what fixed my problem was screwing back the arial. I unscrewed it after going to the car wash...... Toke a while before I knew that was the problem.
my case is , it is ok for turn on, but some times it is not working ( could not start ) and after many attempts it is working. It is bothering me. plz help 🙏
I just replaced the battery on my Mercedes Benz. Now the car cranks but won't start. After like 5 tries it will start. Keys have new batteries and unlock everything. Fuses work. Auxiliary works.2018 Mercedes-Benz GLA 250. Need help.
Not all key fobs are like that I have 2, 2003 Ml350 and someone tried stealing my car so I took the ignition out of the one that don't drive and switched the blades on the key fob and still won't start it
Hi there. I recently purchased a Mercedez 2002 SLK230 Kompressor and I would like to obtain 1 or 2 extra keys and FOBS before I lose one. The dealers are outrageous. And they say the car will be ruined forevvvver if you program it with anyone besides them. Any suggestions to obtain a couple and get them programmed. I have 2 originals now, but I misplaced one somewhere in the house.
I have a 2015 ML350 with this same issue... can you please tell me where and which fuse? I have searched high and low and many things have changed with the fuse boxes. THanks!
I have a weird problem. It seems different than the issue in the video. After my FOB battery died, I used my spare FOB for a few weeks. Then I changed the battery of the other FOB after figuring out how. But now only the lock button and the trunk button are working? Both buttons just unlock the car. They do nothing else. If I click the unlock button though, nothing happens. If I click both the lock and trunk buttons and hold them down for 10 seconds or so, this locks the car... no idea what is going on with the key, but my spare key is working just fine? So I presume the issue must be with the FOB itself? Has anyone had a similar issue and how did you solve it?
Hello there. Recently I replace the batteries but no luck. The lock and unlock buttons work, but the key don't engage to the car. I did the test with the camera and i don't see the red infrared light Any ideas
Hi, I have a 2010 GLK350 4matic...only have one key fob it is not locking or unlocking my car and when I insert the key the message that pops up says “key does not belong to this vehicle” and does not start my car. Changed remote battery, When I click buttons the red light turns on and I can see infrared too. Fuses look fine. Idk if I need a new fob or not because it seems like I just need to reprogram but this is not working. :(
Took it into MB, of course they want to say it’s the ignition and charge me $2,000 but makes no sense to me, why would that message pop up if the ignition doesn’t work?? Obviously it’s reading the key just not recognizing it...?
Because Mercedes benz makes shit cars that have a fuckload of electric problems done on purpose to make mad money off electric repairs which only a dealer can do. Ignition electrics to break is common trust me I have a MB, I wish I never bought it, however I am now stuck with it. Mercedes is not reliable and the electrics malfunction all the time, it’s done on purpose to make money off you for repairs or tell you it’s time to buy a 2019 lmfao fuck benz
Benz are not made to last. A 2010 benz is considered almost at the end of its life lol, they really are shit cars just fun to drive and look nice. I will never buy a MB again because me myself have had countless amounts of electric problems w my car it’s fucking bullshit these cars are NOT made to last.
I have an S400, 2010. The fob batteries are new and I have no infrared transmitting. Batteries in correctly. Car went into alarm mode with emergency key entry and goes off everytime I open a door. Also trunk won't open. Need bew fob?
In case it helps someone, I have fixed several Mercedes keys, if the immobilizer does not work, it is the coil, it must have continuity when measuring the ends with the multimeter, and to see if the infrared works, it is very easy, I know, I know You can use the phone's camera and press any of the buttons and you have to see it, the beam is not centered, it points a little to the side, then the buttons, they are soldered with very little tin and they usually come loose, but they are easy to remove. change.
It didn’t help me 100%, but it did guide me in some tests. Who the hell knew, to use my phone to look for UV Light? Well, obviously this guy did. I narrowed it down a bit, and off to the shop next I think. I have a 2015 Sprinter Van, with about 10K on it. The other key, works well

Does the AAM fuse affect car starting
Answer please
First of all thank you for sharing. Second after 10 seconds I hold the 2 buttons what after it? It's not clear what you said. Thanks.
Check the fuse first, if it is ok it SHOULD show some i signs of life by locking / unlocking the car.
i was playing around with this thinking why it is not working and what are my next steps without checking main step - FUSE.
Hey friend, I have a 02 cl55. Do you know where this antenna fuse is located on the cl? I haven’t seen a fuse box in my truck?
how do I open the trunk if my apparently working fob doesnt open the trunk, even on the door opening button?

@@asapluck3408 It was a bad fuse with partial contact on the right side of the dashboard. you need to open the door to access the fuse board.
What if the red LED light is on the FOB but the car will not unlock with the manual key ?
Thanks for the hints...it really worked magic.
I didn't even watch the video,but like the gentleman

Which fuse# is for my 2009 c300 4matic? Your v iui d doesnt match my fuse box.Thanks
It also might not be in my rear fuse box as well..??
Great video. My key fob red light works most of the time when I push the unlock button and the infrared works as well. However, neither lights work when I use the lock button. Twice in the last three weeks, I had to press the unlock button many times to get it to open. Any ideas would greatly be appreciated.
And what was the reason??
I have the same....( urgent)
Thanks!
@Mohammed Talha okay thanks... I did, brandnew... I guess its something else... I will find it. Thanks
@Mohammed Talha hi can you share the video if you have it ? I can’t get into my s550
The car "picks" up the signal when you press the lock or unlock buttons, as there is a small buzzing noise that lasts for approximately 5 seconds. Although, the doors do not lock nor unlock with the fob. I can still unlock and lock it via the Mercedes me app. Help?

Not all key fobs are like that I have 2, 2003 Ml350 and someone tried stealing my car so I took the ignition out of the one that don't drive and switched the blades on the key fob and still won't start it
Hi there. I recently purchased a Mercedez 2002 SLK230 Kompressor and I would like to obtain 1 or 2 extra keys and FOBS before I lose one. The dealers are outrageous. And they say the car will be ruined forevvvver if you program it with anyone besides them. Any suggestions to obtain a couple and get them programmed. I have 2 originals now, but I misplaced one somewhere in the house.
I have the same issue , do you know which fuse is for w204 250 cdi model 2007?
Thank you for your informative videos
I have a 2015 ML350 with this same issue... can you please tell me where and which fuse? I have searched high and low and many things have changed with the fuse boxes. THanks!
I have a weird problem. It seems different than the issue in the video. After my FOB battery died, I used my spare FOB for a few weeks. Then I changed the battery of the other FOB after figuring out how. But now only the lock button and the trunk button are working? Both buttons just unlock the car. They do nothing else. If I click the unlock button though, nothing happens. If I click both the lock and trunk buttons and hold them down for 10 seconds or so, this locks the car... no idea what is going on with the key, but my spare key is working just fine? So I presume the issue must be with the FOB itself? Has anyone had a similar issue and how did you solve it?
Where can you get the battery?
What do you do if the battery was just replaced, and no light comes on??
2004 Mercedes ML 350 fob which looks different to the remote in your video.
Check the connection points to the battery to see if they are corroded ouie broken. Check to see if you've turned the battery in the wrong way.
Hello there. Recently I replace the batteries but no luck. The lock and unlock buttons work, but the key don't engage to the car. I did the test with the camera and i don't see the red infrared light
Any ideas
Comment changer la clé à contact par la clé à ignition
If infrared light not working does that mean the car won't start
What if the trunk and the unlock button is only working and the locks button isn't what could it be?
What does peace out mean ?

The key won't start my car pls tell me you know why it's not trying or nun I need to move it off the street
Hi, I have a 2010 GLK350 4matic...only have one key fob it is not locking or unlocking my car and when I insert the key the message that pops up says “key does not belong to this vehicle” and does not start my car. Changed remote battery, When I click buttons the red light turns on and I can see infrared too. Fuses look fine. Idk if I need a new fob or not because it seems like I just need to reprogram but this is not working. :(
Took it into MB, of course they want to say it’s the ignition and charge me $2,000 but makes no sense to me, why would that message pop up if the ignition doesn’t work?? Obviously it’s reading the key just not recognizing it...?
Because Mercedes benz makes shit cars that have a fuckload of electric problems done on purpose to make mad money off electric repairs which only a dealer can do. Ignition electrics to break is common trust me I have a MB, I wish I never bought it, however I am now stuck with it.
Mercedes is not reliable and the electrics malfunction all the time, it’s done on purpose to make money off you for repairs or tell you it’s time to buy a 2019 lmfao fuck benz
Benz are not made to last. A 2010 benz is considered almost at the end of its life lol, they really are shit cars just fun to drive and look nice. I will never buy a MB again because me myself have had countless amounts of electric problems w my car it’s fucking bullshit these cars are NOT made to last.
How come no one mention the system battery. in the CL 500 a dead car battery was the issue.
I have a 1999 s 320 and it gives me key error. How do I fix that?
This was so helpful thank you!!! I have a 98 c230 and this is what's happening
Do you any idea what could cause the key to unlock the doors only 3 feet away but in longer ranges it will not work.
Low signal from the fob.
Bad connection(s) for the receiver in the vehicle. Does it work on one side of the vehicle over other sides?
it does not work from the othere sides of the vehicle exept if the key has no case on it. where is the resiver located at the car ? thanks !!
I have an S400, 2010. The fob batteries are new and I have no infrared transmitting. Batteries in correctly. Car went into alarm mode with emergency key entry and goes off everytime I open a door. Also trunk won't open.
Need bew fob?
Battery contact points in the fob are probably bent down. Carefully raise them up.
Thanks for being real.
In case it helps someone, I have fixed several Mercedes keys, if the immobilizer does not work, it is the coil, it must have continuity when measuring the ends with the multimeter, and to see if the infrared works, it is very easy, I know, I know You can use the phone's camera and press any of the buttons and you have to see it, the beam is not centered, it points a little to the side, then the buttons, they are soldered with very little tin and they usually come loose, but they are easy to remove. change.
It didn’t help me 100%, but it did guide me in some tests. Who the hell knew, to use my phone to look for UV Light? Well, obviously this guy did. I narrowed it down a bit, and off to the shop next I think. I have a 2015 Sprinter Van, with about 10K on it. The other key, works well
