Mercedes key battery change

[@KingsOutdoorLife]

11 years later and people still learning from your video. As we say here in Alabama, "Good Show, Mate." Thank you!

[@ultimatehandyman]

Thanks for the comment 👍

[@sillcock51]

This is the best information I've ever found on the internet!!! I could see that the top of the key should come apart, but couldn't work out how to get it apart! You are brilliant and a very generous person to take the time to make the video clip! Thank you sooo very much!!

[@anthonyjtravis]

Crystal clear instructions - exactly what I needed. Thank you so much for posting this :)

[@ultimatehandyman]

You're very welcome!

[@Benbenforever]

I've been looking at this bloody key (spare) for about 4 years and could not work out how it went, so you have given me the answer, thanks a lot, much appreciated.

[@ultimatehandyman]

You are welcome. Thanks for the comment ;-)

[@StreakingTiger]

Thanks a bunch - the absolute BEST instructional video for this process on the internet. Thank you so much. It took no time and was super easy.

[@kimberlyswank8386]

Finally.. This was the first video on this that actually explained how to get the battery out. THANK YOU

[@ultimatehandyman]

I'm glad the video helped Thanks for the comment 👍

[@Techtablets]

Great video, how can anyone dislike this super clear video. Just a tip if others have this issue my contacts weren't great even after a new battery I had issues, using some WD40/CRC I cleaned the inner and outer contacts and inside the fob where the + & - terminals make contact, now it's like new.

[@ultimatehandyman]

Thanks, Haters gonna hate, I'm afraid. Thanks for the comment

[@alexludlam2313]

..mainly I’d say because there is no mention of what batteries are used 🤷🏻‍♂️

[@ultimatehandyman]

@@alexludlam2313 It's dead simple, you look at the existing batteries and get two replacement ones. If you are really smart you can check the description of the video, which states CR2025 batteries ;-)

[@DeaconNorth]

@@ultimatehandyman haha, brilliant!

[@dirtyscavanger]

Hey new owner if I change the battery does it mess with programming? like will I be locked out?

[@rogerserafin]

Saw this video and haven't changed my batteries yet in my 11 year old MB keys. Bought CR2025 3V batteries. Changed them out on all my MB keys. Thanks for the video.

[@ultimatehandyman]

+Roger S You are welcome. Thanks for the comment ;-)

[@barbaragamblecleveland6877]

Thanks so much! I didn't even realize there was an emergency key in the fob and we've had the car for years.

[@lizmwafongo8467]

Me too. Thanks alot. This is a great video. Helpful

[@patrickpurcell3671]

Neither did I nor previous owner he had spare emergency keys cut and on the key ring lol.

[@stevencole4602]

Very useful. I'm very grateful that you just got on with telling us how, I hate 50min long videos telling 2 mins of information. Thanks 👍🏻

[@ultimatehandyman]

👍

[@thebishop1820]

Lifesaver! Thank you very much. This is something you do once in a blue moon, so forget how to get at the battery.

[@ultimatehandyman]

You are welcome Thanks for the comment

[@MrGOZATELO]

JUST GOT THE C250 AND THE KEY WAS ONE OF MY MAIN ISSUES….YOU REALLY HELPED ME. THANKS

[@tonydicks3291]

just watched this, so perfect to follow, many thanks for posting this handy tip, Tony.

[@ultimatehandyman]

You are welcome Tony, Thanks for the comment ;-)

[@mikefergie647]

You have saved my day with this. Dropped keys in a puddle -soaked. Had to walk home thinking the worse, key key fob etc. Found your vid, took key fob apart now slowly drying out. Will give it some new batteries as well. I just hope my attempt at getting the fob to work by pressing the buttons whilst it was wet hasn't damaged the circuit board. Many thanks again 👋👍

[@ultimatehandyman]

Great to hear!

[@ceciliefrederiksen5405]

THANK YOU from a lady in Denmark.

[@Outlawjankooo]

Hvilken mercedes har du?

[@HoneysAstro]

I honestly don’t understand why this got so many dislikes. Lol. Got a battery and fixed my key within the space of 3 minutes after watching this video. Clear instructions. Easy to follow. HD quality. What more could you need. Thanks pal.

[@ultimatehandyman]

Haters gonna hate ;-) I'm glad you found the video useful. Thanks for the comment

[@vitaliyilich]

Thank you for the video. Why would anyone dislike this?

[@ultimatehandyman]

You are welcome. Some people dislike videos because they have nothing better to do. In the years I have been on KZbin I think I have only ever disliked one video, which had a misleading title and thumbnail. Thanks of the comment

[@monikapetrova5482]

Dislike because they dont have a mercedes . :)

[@HGHONDO]

Unfortunately some people are assholes

[@amojak]

because some people make big money out of doing this for people who don't know how :)

[@gispaceuniversity2005]

That is a CR 2025 battery. Radio Shack sells them by 3 pack for $12. Thank you for the video, which saved me a trip to the dealer.

[@stevewilson7857]

$2.00 for (3) on ebay

[@garymorgan8786]

Great stuff - thanks a lot for sharing! Saved me a few quid as the local MB dealer wanted stupid money to do this!

[@julioalbertoherrera1339]

I got the change for about €7.50 (€3.50 for each battery) 🔋

[@dwappie]

Thanks from Holland. 1rst time in 7 years i had to change the battery after the keys went in the washing machine 😎 first tried it myself 20 minutes. Then watched your video and 30 seconds later i could drive my Mercedes again 👍🏿

[@ultimatehandyman]

I'm glad the video helped Thanks for the comment 👍

[@Kewebu]

Well, Thank you kind sir ! You spared me some frustrations and time :-)

[@ultimatehandyman]

You are welcome ;-)

[@MrMatanX]

Thanks very much. You practically helped in saving me from losing my new job on the first day. The fob wouldn't unlock the car 30 mins before I was to report for induction and using the emergency key did the trick. Cheers.

[@ultimatehandyman]

+Sam Matankari Hi Sam, that's a great story. I'm really glad the video helped you ;-) Good luck in your new job!

[@mikeone718.]

you're the man. thank you for this video

[@ultimatehandyman]

+Mike J Thanks for the comment ;-)

[@chriscopland2459]

Thanks for the clear how to Video, I don't like damaging anything when replacing the batteries because of the very clever manufacturing these days everything is like a secret lock box.. And the comment saying what batteries was just that little bit extra, much appreciated !!!

[@ultimatehandyman]

You are welcome 👍

[@rootofminusone]

thank you, and god bless you it was a mystery to me before I watched this video haha

[@byronfalls1608]

Sir, this video was incredible. My 76yr old mom appreciates it. Her key works now. :) Thank you again - so much!!!!!!

[@ultimatehandyman]

+Byron Falls You are welcomeThanks for the comment

Amazing! Am very grateful for this clip. Thanks men! Max.

[@ultimatehandyman]

Nelson Okeke You are welcome Thanks for the comment

[@margaretcarron8692]

Thank you very much for sharing! I thought my key fob was going to be written off as i couldn't see any way of opening it to replace the battery. But miraculously you've saved my day! Thank you

[@ultimatehandyman]

Glad it helped!

[@RobertPlattBell]

Thanks for this video. A friend of mine called tonight, locked out of his car, and I was trying to explain to him how to get the emergency key out of the fob, and I sent this video to his cell phone. Bummer is, his car battery appears to be dead. Oh, well!

[@ykhan7017]

Just wanted to say Thank you for this video. It saved me alot of time. Took me no more than 1-2 minutes to get the job done.

[@ultimatehandyman]

I'm glad the video helped Thanks for the comment 👍

[@ultimatehandyman]

@ Kami Sama Perhaps you would like to watch the video again- “If you press any one of these three buttons and the little LED does not light up, it means the battery is flat”. I can't make it much more clearer than that. 638,000 other watchers have not had a problem understanding ;-)

[@Thetruthdenied]

+Ultimate Handyman agreed, it is very CLEAR!

[@thrivingways9124]

my key is showing the red LED but not locking or unlocking the car. any other suggestions?

[@ultimatehandyman]

I'd remove the metal key and try that?

[@ultimatehandyman]

No, if the battery is dead the LED will not illuminate

[@leeoshea2290]

Thank you for this very informative and clear photography of this MB key fob I'd opened mine years ago and forgotten about the push 'bit' inside to release the battery holder CR 2025 in mine for those coming after me: 20 (20mm) is the diameter 25 (2.5mm) is the thickness the numbers are important, thinner batteries don't make a connection and thicker batteries won't go in the holder.

[@krzysztoflorenc7166]

Well done. Very good and clear video. Just come back from Timpson's and they couldn't change the battery because they said the fob is sealed and I need to visit mercedes. After your video the battery changed in no time.🎉

[@ultimatehandyman]

Glad it helped 👍

[@amankaur8934]

very clear instruction!! we were having problems for months and watching ur video sorted it all!! thanks

[@ultimatehandyman]

I'm glad the video helped. Thanks for the comment

[@NewShockerGuy]

Just got a clk320! Fob's batteries DONE! This video rocks thank you, They both work now after swapping to new batteries!

[@ultimatehandyman]

You are welcome Thanks for the comment

[@igorboskovic8566]

I went to auto zone and they had no idea how to open this key than my friend showed me your video so I opened it on my own and went to get new battery, rn it works perfectly thanks a lot.

[@ultimatehandyman]

You are welcome. Thanks for the comment ;-)

[@SuccessCoach1]

Thanks, you made changing the key so simple!! I used to go to the dealer prior and it cost me a lot more than just the cost of the battery. So much to learn on You Tube!

[@ultimatehandyman]

Glad it helped

[@malcolmjames7388]

I think you make your videos so clear and easy to demostrate.i love watching all your videos. Thanks and keep it up

[@ultimatehandyman]

I'm glad the videos help ;-) Thanks for the comment

[@mohammedashfaq3734]

Many thanks. Instructions were nice and clear. However, took me ages to put the clip back in place but I got there in the end. Have a nice Christmas.

[@patrickpurcell3671]

Thanks for making the video. Very helpful. I had watched others but did not explain the procedure as well. I had to clean and adjust tension on the battery connections for mine to function.

[@NaveedKhan]

And all this time I was thinking I'd have to find a replacement for my key fob. Thanks so much for this!! Going to pick up two CR2025s right now!! Keep up the great work!!

[@ultimatehandyman]

You are welcome Thanks for the comment

[@NaveedKhan]

***** So I changed the batteries in the remote, but, I'm still not able to get it to work the way it's supposed to. The reason I changed the batteries was because I couldn't get my car to unlock unless I pointed the front of the remote directly at the IR receiver on the door handle at a distance of not more than an inch or two. Still getting the same issue even after changing the batteries...

[@ultimatehandyman]

Naveed Khan Were the new batteries good quality ones? Sometimes if you buy cheap ones they are not so good. I'd try a new pair of batteries and if it's still not working you might need to take it to a Mercedes specialist to find out if it's the key fob or the receiver that is faulty.

[@debralevine5287]

Thanks so much! Saved me $35 from the dealership. Perfect instructions.

[@ultimatehandyman]

I'm glad the video helped ;-) Thanks for the comment

[@ultimatehandyman]

I'm glad it helped ;-) Thanks for the comment

[@RiverVmanna]

Thanks very much for this. I have been leaving the doors unlocked for six years. Even at concerts and busy downtown areas. No one has even tried to open the door once in all that time. I know because the passenger door unlocks when the driver door is opened. Now I can use the fob again. yay!

[@ultimatehandyman]

Thanks for the comment ;-)

[@asaelvasquez4956]

Thank you, you saved me a lot of time figuring out how to do it.

Thank you, you saved this sunny day and my beach trip

[@ultimatehandyman]

Enjoy!

[@pilatesfitness8766]

Great instructions. Was able to follow through with no issues. The only problems: 1) I don't have an LED telling me if the batteries are fine or not; 2) after the battery change, my key fob still is not working. Time to call Mercedes again...

[@ultimatehandyman]

I hope you get it sorted 👍

[@shahdrah]

This video came up at the perfect time. My fob definitely needs a new battery. Thanks again Ultimate Handyman 👍🏽

[@ultimatehandyman]

Glad it helped 👍

[@sobhashjethwa754]

Good work. The manufacturers try and make it more complex than it needs to be. The emergency key is simple enough. But to remove the battery there is a small catch inside!! WTF. I'd never have thought. And there I was going to use a thin blade to try and seperate the key fob!!. Thank you for the video.

[@ultimatehandyman]

You are welcome Thanks for the comment
