Mini Cooper key fob Battery Replacement 

I love how many people complain about a FREE INFORMATIVE VIDEO that someone else took the time to make to help others. If you feel like complaining maybe you should take the time out of your life to make a video. Thank you for the video!! Most of us Mini owners appreciate it.

you saved me! Mini cooper gave us an outrageous cost for replacing our keys and found this video....will be trying it this! Thank you so much!

Great video! Worked a treat for me. A bit scary knowing what's on the line, but with some time and steady hands I had no issues. Thanks!

I appreciate that you also added the battery type in the Discription.

Thanks for the info. I couldn't get mine apart with the blade. I was scared to push any harder, mine was glued together good. I used a grinder to take off enough material around the perimeter.

Great video that will save me hundreds fixing my Mini key. Thanks for doing it. Soldering tip: you don't need flux when unsoldering. Flux is an acid that cleans the joint when RE-soldering, so the parts stick together without impurities which prevent a good joint.

Jeez... I’m stoked right now my R56 came with a 2nd key, I’ll go try find it now, and what the F were BMW thinking? They did a great job at making this a super hard task.

Thank you for the video, I followed the method, perfect ! 👍👏

That is insanely complicated. great video!

How do you have so many views, but no likes? Lol. I gave you a thumbs up. Screw Mini Cooper, I swear.

I was about to do this on my remote which looks just like this. I mostly take my Mini on short 20min runs to do shopping twice a week so the remote is now starting to act up. I'd take the car into town then it wouldnt lock the car id have to do it manually. Then I read you can charge them via a toothbrush charger and by chance we had one. It was awkward sitting the remote on it because of the shape of the charger but it actually worked! It didnt last long unfortunately, the battery needs replacing. Try charging it first and leave it on it overnight.

Excellent video well done mate. I notice a few are stating they state an easier way just popping open the case, that is ONLY do able on a completely different fob, SADLY BMW designed this fob uniquely hard to change a £4 battery and crazy ! The only way IS as stated by carefully cutting open the remote case with a blade as described so well done poster. This remote battery only operates the lock and alarm, if it fails open car with the metal key and place the remote body in the remote holder in the car and the alarm will stop and car will start and carry on as normal. BMW sadly avoid instructions on replacing the remote batteries which is obvious by its absence, I believe they hope everyone will just buy a new car every 5 years ! We purchased a new mini and only ever used one key fob, sadly the second fob battery died. What instructions they do give is make sure you use the remote twice per year however they fail to explain why, which obviously means the batteries go flat unless charged. JUST BE CAREFUL USING THE CUTTER.

It worked, yay!

Nice vid. Thanks for your time, it’s very much appreciated Buddy.

How about immobiliser ? Is it build in or it’s inside the key fob ?

Integra DIY, thanks for this video. . 😎

personally i would be interested in if the loading in the key slot still works because anode and cathode are connected to straight connectors instead of circulated like the OEM-cell. because of inductive loading and its architural requirements O_o

Thanks to the maker of this video. I had 2 fobs and one stopped working while the other continues to remotely lock and unlock doors &etc. I checked the battery from the fob that stoped working and it was significantly lower voltage than the new one I bought for this project. I changed the battery and it would not operate the remote features. Any one else run into this and what was the fix? Many thanks

Thanks for the upload. Did this and key works great , however i still get the Error ( key with a line through it ) regularly .Is there a reset for this ? cheers

Thank you a lot!

Gracias por el vídeo, en el concesionario BMW, me piden 181 euros por 1 llave nueva.

hi thanks for the video, what material is it that you use to stop the pile, min 10:38? can not you use the pond? thanks !!!!

What a great video... thanks! My mini is a 2008 R56S and i dont see any signs of battery to be degraded. Did u notice that your battery needed to be replaced and if so, what gave you that idea? Also i cant find a shell with the mini logo on... where did u get yours?

Ugh I’m too much of a wimp so I’ll head to my dealership :( thanks for the video tho!

thanks for the video! where have you bought the replacement key?

Just tried this myself, unfortunaletely i cut too deep en pushed/broke the locking-switch of the circuitboard. So if you try this, be very carefull when cutting and take your time.

Great video. Only thing after i replaced the battery it didn't work till i put it in the docking port. Again much appreciate the video i would of destroyed it for sure.

Thank you 👊

great video, but i decided to sell my mini after knowing how much they hate their users.

Hi thanks for the video, could you tell me the name of the knife you use to open the case with. Thank you

How long will a battery last before it needs to be changed? I got mine out that's from 2013 and it tests 3V still? Thanks for the video!

What year-range is this for? The garage I take my 2012 Countryman to, they simply popped the back cover off at the little notch, popped the old batter you and a new one in. Been working like a champ, since then.

Quick question. Why did you replaced the battery? Did it stoped working (opening and closing the doors). The old battery was not recharging anymore? Please let me know because i think this is what it’s happening to my fob. I have a 2008 clubman s and it does. It close all the doors or opens a only the front but don’t unlock the back left door trunk (behind the driver ) it started today

Thx very much. I've found the way for long time that how to change the battery. That is idiot design from Mini. If you need to replace the battery, you have to buy the whole key that too costly.

What was the reason for putting on a new case, or wouldn't the battery charge anymore? When unsoldering like that I heat the solder and using an air nozzle and quick puff of air I blow the melted solder away.

I bought a replacement battery but didnt come with that metal bit attached to it.where do i buy a battery with the metal bit attached please???

Hellow what is the model of the batery. Thankyou from Chile

New fob and new key how to program

U have a link to where u bought ur spare?

Wow, my son's needs a new battery and could not work out how to get into it. Cannot believe the trouble it takes compared to other cars. BMW really don't like you to do it yourself do they?

Thank you very much for helping mini cooper owners 👍👍👍💪🦾❤

I have no battery on mine? R60 countryman... My car has confort access and I don’t know how to send pics

Me gustaría saber si el botón de arranque está duro de mi minutos o es blandito

Great video and content, but WTF is the deal with this battery change needing a soldering gun? Not your fault I know, but dang why did BMW do that?

What’s the most affordable option if you can’t do this at home? I tried auto part store and nobody is up for the challenge. I heard they charge a ridiculous price at MINI so any alternative suggestions?

what glue r u using

How did you get the silver coloured metal trim/ring off, and then back on, please?

Here I thought it was going to be simpler than this...

Thanks for the info, although your soldering skills are very lacking, still some good information here.

Alguien sabe a qué temperatura debe estar el Cautin ??

Jack FM ... :)

Why would this be rechargeable? Is there any documentation that this is a rechargeable fob? It looks like a standard lithium battery. Why would this key fob need to be charged? My Honda key fob is 10 years old and has never been charged

Number for battery required would have been nice.

O pil şarzlı değiştirmeyin !... zaten bulamassınız piyasada.

so I did this.. fob worked, didn't fix my issue, something happened and now the fob doesn't work at all 🤣 I'm worried about putting my spare in, I think i might have burnt a chip or resistor when I plugged it in

U shouldn’t hav to change he battery as it charges when in the ignition slot’Ive used both my keys for my 2007 r56 and Berger had to change so far so good

Where can i buy the battery and is it 2032 or 2020

Thanks for the how to, but what is the point of buying a new key fob if it doesn't self lock and unlock more easily. Using crazy glue to secure the new case is just the same as gluing the old case you cut through.

I need to buy a box cutter, a soldering iron and a glue gun to change the battery for my 2012 mini copper countryman key fob. You have to be kidding me. What the heck.😢

Whassa badderee

A little bit more than is necessary…

Using a blade to open the fob makes no sense. The manual says to just remove the cover to replace the battery..nothing about having to take off a seal to replace a battery.

I replace the battery but not change the key fob housing and it didn’t charge up :,(

A razor blade? Is that how BMW intended this to be done?

Eror punya sya 1 krn ga prnah d pake

It looks like a capacitor ... not a battery!

6u

WANTED TO KNOW HOW TO TAKE THE RING OFF THE FOB!!! SMDH!!!😖😖😖

People, you do not cut open key fob housing! They pry apart with a screwdriver unless the housing was glued together by previous owner or yourself!

Not for 2011 mini cooper!

Reason #98367 that I hate Mini Cooper!!!!

WTF?? BMW shit the bed on a simple procedure!

THIS IS WHY I TOLD ALL MY CUSTOMER TO STAY AWAY FROM MINI CAR. POOR DESIGN

All this crap just to change a bloody key fob battery honest to christ 🙄

Please do this to your key only if you like slicing your hands open with that boxcutter and only if you like slicing critical components off of that circuit board! A box cutter IS NOT the way to open these keys! This is not really a DIY job unless you are familiar with miniaturized electronic devices and are skilled at soldering. Besides, changing out the battery will not fix a key that is not starting the car and changing out the battery will not solve the other problem that these keys develop where they drain even a new battery very rapidly. This was just painful to watch.

Wow, you really need to work on your video skills.
