They're actually two types of old keys. The one is you describe that the back cover pops off and another type that the whole cartridge slides out. If you have the one with a cartridge slides out you will tear it up. Trying to pop the cover off. I don't know what year it is but you should add that to your video 5:12
Thanks for the suggestion! It’s tricky I thought I’d produce a video on how it works but my local Mercedes only had the keys shown in the video as dealerships tend to only keep cars over the past few years.
Would be happy to produce the video again but it’s finding the key even before that that’s tricky.
Thank you! Although my dealership does this for free, you saved me the time to drive out there. Thank you!!!
Ah awesome thank you! 🙏
Thank you for sharing your knowledge! Made it easy and simple to replace my battery to the remote. Thanks again
Ah thank you! Glad you enjoyed the video!
Thanks Nick my key fob stopped suddenly last week with out warning!
So taking in for diagnostic check
Great advice on all your reviews.
Thanks
Thank you so much. Very easy to follow instructions for a numpty like me 😂👍👍
No worries! Glad you enjoyed it!
I’ve watched most of your videos now and the videos are absolutely tip top for anything Mercedes’ clear precise and very professional well done mate
Thank you very much! 🙏🙏
Glad you enjoy them!
Thank you you are amazing !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thank you!
Thanks Nick, another great video! Keep them coming!
Thank you! Will do! 🤓
Thanks Nick..
Just bought a GLC Coupe 2022. This channel really helping through the learning curve 🙏
Thanks Tony! Glad you’re enjoying the videos! 🤓👍🏼
Super helpful, thanks so much!
Thanks for the info, it helps!
Thanks for another useful and informative video Nick 👌👍
No problem Mark! Glad you enjoyed it!
In November I had my 2020 E 350 in for routine service. Per the maintenance schedule, they replaced the battery at a cost of $25 (£18). I can buy 2 batteries at my supermarket for $3.25 (£4.45). This is a hell of a tip! 👍
Well, the charge is mainly for the person fiddling with your key to do the replacement.
It's insurance. If they damage the key they have to buy you a new one.
Thanks for the info! Great video, so simple once you know but had no idea! 👍
Thanks Billy! 🤓
Superb thanks
Thanks for watching!
Fantastic video..worked like a charm..thank you.
Thank you! 🤓
That old key is the nicest one they've made. It felt heavy and expensive and the battery was lovely to change.
Hi Nick I have an old style key. I think you rushed the “turn the key around” tip. I had to watch another video to understand it. Just an observation as your videos are superb.
Hi Nick, very useful information thanks 🙏
Thanks Jag! 🤓
Another useful and informative video Nick. Thanks mate 😀
Thank you Darryl! 🤓
Glad you enjoyed this week’s one! 👍🏼
Working on next week’s already! 🤫
@@npoleary Can't wait mate. Thanks so much for everything you do 👍
Informative 🔥🔥🔥
Very easy. Thank you
very helpful. Also top tip check the spare. It never gets used and then when its needed....flat battery!
Nice to see the simple things covered, tried doing this on other vehicles and it can be a struggle so good info.
Can you do a tyre pressure video Nick.
Thanks Paul! Already beat you to it 🤓
I feature this on a TH-cam Short 👍🏼
th-cam.com/users/shortsuivtGMxAA6U?feature=share
Handy to Nick top man thanks
Thanks. V clear, v helpful
Thank you! 👍🏼
Just to add to Nick's great video.. I used to experience a fair amount of people who said that they'd changed the battery but the key still didn't work. When we changed to a Mercedes supplied battery the keys then worked. No idea why... I'm guessing there are some cheap batteries on the market that just don't cut it, so best to ensure its a quality branded type to be safe.
Just use 2032 batteries from any brand, you will be fine. There are 2025 and 2016 bateries won't work because of the energy they provide are less than 2032, will not cut for the new MB keys.
Thanks
No worries!
Good video again, top tip all worth their weight in gold
Thank you Neil! 👍🏼
Glad you enjoyed the video!
POWERful video Nick, very POSITIVE, hope you're not going to CHARGE for the advice, that would be NEGATIVE. 😁
Hey Gary! Thank you! 🤓 glad you enjoyed the video! I wasn’t planning to! 😅 haha
Thanks for the useful info, especially for the new key. About a month ago I had an issue where the car would not start due to key / battery. Unlike the older key, where you can remove the push start ignition button and insert the physical key, on new cars this is totally different. Maybe you can do a video on that as it can be helpful.
Absolutely! I’ll add it to the list for potential future videos 🤓
Make it simple straight to the point
Great video I can't see the link for the old style key fob battery CR2025
The links are there
When I made the video, I pinned them to the top of the comments section and added them to the video description.

Hi Nick, I enjoy your videos but have a question. Can you make a MBUX command from your own. Like He Mercedes start dashcam
No sadly you can’t :(
That would be pretty cool though making your own commands for the system! 🤓
Glad you love the videos! 👍🏼🙏
Hi Nick, thank you very much for all these amazing tutorial videos! It is very helpful. Recently I just picked up my 2022 GLE 450 and watched you all the tutorial videos, including that 1 hour MBUX movie! :-) However, I find there is 1 thing you may didn’t cover, which is the “ECO assist function” (I know you had an ECO display video before). In terms of ECO assist function, I notice there are several displayable route events and the “Foot off the accelerator” prompt symbol. It would be great if you could do a video to explain ECO assist function in details! Many thanks in advance!
Thank you MJ Liu! Glad you enjoyed the video!
I’ll add Eco Assist to the list of potential future videos 🤓
Hi Nick
Due you know if there is a time limit after the battery is removed before the key loses all the programmed information and then won’t work ?
Regards
Geoff
Hey Geoff, I don’t think so
It should stay programmed to the car as far as I’m aware
yet another brilliant video Nick, thanks. QQ - is there a way to link a key to a profile? Ideally the key would then recognise the profile & adjust seat mirrors etc so I didn't have to squeeze into the car after my wife last used it.
Hey Paul thank you! No sadly the keys are just as they are and don’t have any correlation to user profiles in the car. I know that other manufacturers have done this but then you’re limited with users to the number of keys, in most cases…2.
In Mercedes with profiles you can have up to 7 profiles so 7 users instead 👍🏼
@@npoleary Thanks for the knowledge share :) The Easy entry/exit seat function doesn't seem to move the seat - just the back, which is why I was hoping the keys would link to profiles. I know on my 2020 A Class Premium Plus the steering wheel is manually adjusted. Are the seat memory buttons linked to the profiles or are they independent? Just trying to find the best way of having enough space for a big guy getting in after a small person was last to use the car :) Perhaps I have to use those to get access?
Hey Paul, they should be separate as far as I’m aware
The Easy Entry & Exit will only operate when it’s fairly close to the steering wheel anyway 🤓
Hello, I hope you have a great day. I want to ask a question. I just bought a Mercedes glc (2020), and I was wondering that can I store the cars key during driving in the center console, in the cup holder where is the marked zone of the emergency operation mode for the key? Will it confuse the car that I want to start it in emergency operation mode or something like this? Thanks for your answer!!!
Hey Balazs, yes you can store them in there. That’s just where the receiver is located in case there isn’t any power in your key 🤓
@@npoleary
Thank you very much!!!!
No worries 👍🏼
Hello nick do you have any information about when Motability cars will be back on the Motability scheme. or when do you think it will be ? Thanks
Hey FaZe END, really sorry I wouldn’t know however you can keep an eye out on the motability website. The second you see Mercedes-Benz there, you’ll be able to order one 🤓
I imagine it’ll be when the semiconductor shortage get’s better and supply isn’t an issue 👍🏼
@@npoleary thanks nick
Thank you! This will be very useful one day.
Once I payed the equivalent to £27 on a Portuguese Mercedes dealership service just to change the battery. I was appalled. Although I have the money to pay for a useless service like that, I think it was just absurd. And the worst is that I saw the “work” being done and the guy didn’t have a clue. He was trying to figure it out... It was awful to watch because he even let the key fell on the floor!!!
Hey indy4fly, glad you enjoyed the video!
Hmmm, that does sound quite expensive to change a battery!
Do you know if Mercedes check key battery health each service and replace battery as part of service?
Yes they do 🤓
On Mercedes servicing at a main dealer, they change the battery on a B service for you (the major service)
Hey Nick ! Thank you for all the effort in making this videos.
I'm the happy owner of an W177 A class bought in second hand and I have few questions for whenever you'll have the time to answer.
After changing the key battery, should the message automatically disappear from the display? If it doesn't, it means the battery is still bad? I put a new 2032 Varta battery, should we use a specific brand maybe? Thank you for your time. Cheers.
Hey LikeAn00b, ooo very nice!
Yes it should disappear, after changing. I’d see if it just a delayed message and see if it goes the next day or something.
Hi Nick, I’ve already replaced the battery in my Mercedes ML250, but the low battery alarm still appears on the screen. How can I clear this notice?
Hmm strange it should change straight away
Sadly not been in an ML 250 so not sure if there’s a hidden setting.
Just thinking outside of the box, have you tried replacing both key batteries?
@@npoleary Yes. I replaced both.
Hmmm strange might be worth giving Mercedes a shout and see if they have any suggestions. I’ve not heard of any hidden settings to clear it or anything.
I’m sure they might be able to sort it for you!
on the next video can you review the GLS 580 or 63 please coz that is my dream car I appreciate it if you do that.
Sadly haven’t seen a GLS for a long time as they’re quite rare!
But…have you seen this one? 10 Things you need to know about a GLS: th-cam.com/video/Haaa-pMOEHs/w-d-xo.html
Hi Nick, I changed mine a month ago at 3yrs old. Don’t know if it had been changed before. Worth mentioning again to turn off the spare key to save the battery? I remembered you recommended it in a previous video.
Absolutely! I’ve covered it on a tips & tricks video previously but wanted to keep the duration of the video as short as possible 🤓 but yes you’re right it does save the battery 👍🏼
@@npoleary can you please guide me to the previous tips video regarding ‘turning off the spare key’ as I’m having issues with battery life being very short in both keys.
FYI I have tried to do the double click to prevent draining the keys batteries, to no avail. My vehicle year of manufacture is 2012 E250. I bought it 4 months ago and already had to replace both batteries twice. Other than this she purrs along beautifully.
Appreciate your informative videos, they’ve saved me from calling out for help several times 😊
Thanks Alex!
Yes the link is here:
th-cam.com/video/omt_MIepoq8/w-d-xo.html
Although I’m not 100% sure that it would work on a 2012 Mercedes (you can tell if the red LED flashes on the key when you double click it)
Have you spoken with your local Mercedes? Could be something wrong somewhere? It should last longer than that!
@@npoleary I think you’re right in that it’s not available on my older car.
I will take your advice and speak with my local dealer here in Queensland about it chewing through the batteries.
I appreciate you taking the time to respond so quickly, you really are lovely cheers
No problem at all! Hopefully they’ll be able to help or at least find out what’s going on
It would have been helpful to see the position and entry of the key into the fob for the demo of the previous key batt replacement.
Thanks for the feedback! 🤓
Always aiming to make the videos better, I may remake this one in future!
The MB dealer asked 50 dollars to change the battery on a GTS.. on my dad his RS6 (Audi) they just changed it (right in front of us) and only asked the price for the battery itself instead of 50 dollars of nonsense
Hey Gyula, that does sound quite steep to change a key battery! Where was that just out of curiosity?
💯
This does not seem to work on my new style key fob. Any suggestions
Sadly I’ve held the new style key before when reviewing new Mercedes but not seen how you change the battery. If it’s the new style key I’d suggest just visiting Mercedes, they’ll give you a hand in changing it 🤓
for older modal's key, 2035 battery is best fit but 2032 also works
did you mean 2025? In vid he states 2025
👍👍👍👍
Mine is different on the inside. Has 2 batteries, and the back doesn't pop off. Rather, it slides out.
Oh interesting? Is it the new style round key I’ve seen?
i cant get the battery out ?????
Hey Echo Guy, with the previous key, you can normally pat it out in your hand once the covers are off, however if it’s the newer style key, it’s located in the small slider when the cover is off.
If you’re stuck just get in touch with your local Mercedes, I’m sure they’ll be able to give you a hand.
Please get rid of all that fluff of buying car etc. Just talk about the subject.
Also emphasize on important thing like exact position where the key has to be inserted in the fob opening slot to open the fob lid. Thank you!
I might remake this video for the future and see if I can shorten even further. Thanks for the feedback! 🙏
Thanks for no close ups 🤣
Why does it take two minutes for you to get to the part we actually care about
Always working on trying to improve the videos so thanks for your feedback 👍🏼
I guess it depends on the key, there’s two tutorials in one video and links to the batteries
However if you’re after faster paced content, try my TH-cam Shorts: th-cam.com/play/PLyo-duQc8myq_r3selLPQO06yN6UqbcTw.html
Super fast paced! 🤓 💨
@@npoleary Yes. The greatest invention from google was linking TH-cam videos and cutting them straight to the part we’re the tutorial begins. I don’t like to sit in a hot garage waiting for a “TH-camr 2 minute into” to finish so we can get to the part of the video we want to see.
Same reason I don’t play my intro anymore, straight into the content!
I defo try and keep my newer videos my engaging and faster paced! Shorts even faster!
Thanks for watching! 🤓🙏
The most important part - how to open black cover on the old key is not shown! Just wasting of time
Hey thanks for your feedback, I’ll try and recreate the video in the future
Thank you!
