Mini Cooper key fob Battery Replacement

[@IntegraDIY]

@@johnviera3884 The battery in this video was replaced with a brand new battery, the battery is charged automatically when it’s inserted into the fob port while driving. The battery goes bad after years of charge cycles. A new battery must be soldered in when keyless entry doesn’t work.

[@Corysworld26]

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

[@Tania-km6nx]

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!

[@monkeyfinger7949]

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.

[@earlbee3196]

Great tip thanks for sharing.

[@sassyrav]

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.

[@IntegraDIY]

Anonymous Person that’s great it worked out for you. But that’s only if the battery is low. If the battery is old, and it won’t hold a charge, the battery must be replaced.

[@sassyrav]

@@IntegraDIY Yes, ive got this video saved for when that happens just thought it might be worth mentioning before drivers cut the key open

[@pablosanfabio3040]

Good info I change my battery and it still don’t charge, I may have issues on the car side so I’ll try this out

[@glenntaylor6768]

Actually the manual for my 2008 does say you have to use the key in the car a couple of times per year atleast to keep it charged.

[@DarknEssMGs]

The batteries charge from the ignition by default, so you might have a faulty ignition. Also general pro tip - if you have a spare key with a rechargable battery you should use it a couple of times a year so the battery doesnt "bottom up", eg die prematurely. Youll probably not know if a key a has a rechargable one, but a rule of thumb is everything related to bmw, mini, land rover might have one.

[@metalmachines6ix6ixcrush68]

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.

[@sshaunss]

They were thinking how can we rinse people out of £100s I just laughed my ass of at them when they said

[@DarknEssMGs]

@@sshaunss its not a scam in itself, most car keys have single use batteries that last 2 years as a rule of thumb, rechargable ones last 10-15 years, are also sealed shut so less chance of water damage, well, untill you break the buttons. And pretty much anything non japanese with a single use battery has a nasty chance of desynchronizing from the car, which isnt really a problem, but i guess in england it will cost you an arm and a leg to sync again given that a rechargable bettery change is 100 quid. Id say the rechargable battery model is more user friendly, you buy the car and forget about the key, chance is youd replace the car before the key will bother you, tho 100 quid is a bit too much

[@harleyneish8409]

They were thinking how can we get more money out of our customers in the future?

[@omorin34]

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.

[@brendenmoldy]

That is insanely complicated. great video!

[@alm7707]

not so much complicated....Installing a timing chain in your mini...that's complicated.

[@Realer1972]

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.

[@David_Powell]

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

[@IntegraDIY]

Fingernail and pry off

[@David_Powell]

@@IntegraDIY Thank you!

[@alm7707]

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.

[@IntegraDIY]

You can reuse the old case. The original case was old, scratched and grimy.. and had super glue all over it. I highly suggest keeping your original cut key blade, and popping it into a new fresh case.. makes it all feel good and legit

[@Live_in_the_sunshine]

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

[@IntegraDIY]

It wouldn’t charge anymore, keyless entry stopped working. Got annoying having to manually lock and unlock the doors. I don’t think your battery is dead, because it won’t be able to function at all, but it’s not working unlocking the rear doors, so it seems like a bigger issue. If it was a dead battery, it won’t unlock or lock at all

[@jasonwilcox9741]

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???

[@iga5008]

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

[@gordonsinclair9603]

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.

[@tasharedden2088]

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

[@IntegraDIY]

Jamie Ott I disabled them, people dislike the video because you have to actually solder the battery in instead of just popping the old one out and pop the new one in.. this one actually takes a tad bit of work. I love minis man, the jcw’s are cool

It’s typical for German vehicles and slog of foreign car companies.. even their engines need some proprietary tools that have to be purchased by BMW and average tools will not work for certain repairs.

[@williamcannon2825]

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!

[@IntegraDIY]

I’d say they last 8 to 10 years considering they’re always getting recharged during a drive, and after a while the cell dies. My mothers mini is a 2009 so it lasted 8 years. I don’t think mileage plays a part since her car has 89k miles so it doesn’t matter how many miles it’s been on the road. You still have a good while before your battery won’t hold a charge 👍

[@davidswanson9501]

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

[@IntegraDIY]

The fob is not programmed to the vehicle. Find a procedure for programming online, or go to the dealer and have them program the keyless function for that fob

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.

[@IntegraDIY]

Thomas Jones I believe yours has comfort access.. which has a little door in the back that you can access the battery. This is for the 2nd gen mini hatch that recharges using the key fob holder

[@Soapsneaks]

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?

[@IntegraDIY]

other option would be: Manually lock/unlock the doors with the key. Ask your whole family if someone knows basic soldering skills, ask a friend, friends friend, friends moms uncles sisters dog who has an owner who knows how to solder. find a someone who can cast a magical spell on the battery to work again 🔋 ⚡️ 🧙‍♂️

$11 batteries from Amazon. Was careful taking the original fob apart so no need for replacement fob. So $11 and about an hour of time.

Research I did states capacitor on board might last 30 minutes while swapping soldered batteries to KEEP the Program or Code revolver codes to lock n unlock.....I'm assuming before change ..charge what's chargeable before swap so as not to lose program code revolver data.....if seal or seam is glued...ONE would slice carefully but I BEG to use DREMEL....like everyone says....you might slice in TOO FAR an damage the board component...YES ODD why it's so TUFF for DIY....proprietary HURDLES.😅

It should still charge even though you used the old original housing. Check your solder connection and make sure you put the battery in correctly, and make sure you used the proper battery

[@pablosanfabio3040]

Hey legend Yeah I was worried with new battery’s joints not looping around like the original so check back to this video and it’s all identical to what you used so maybe I got a dodgey battery because it came with no power and won’t even switch brand new

[@TimVo]

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.

[@IntegraDIY]

Replacing the plasic case is definitely optional. But the original one was beat and worn out by previous owners, a new case freshens everything up.. for an additional $25 and the benefit of having an all new setup was a bargain. And you are welcome thanks for watching man

[@Cosme422]

@@IntegraDIY Fair enough. Let me ask a different question. Does the car’s owner’s manual have the instructions on how to replace the fob battery? And the reason I’m asking is because I went to youtube trying to figure out how for a 2011 MINI which belongs to my daughter. We don’t have the manual for that car. However, for my 2015 mini the manual has the instructions. The fob is opened with the key. etc. So maybe I need to search for her car’s owner’s manual online to see what the instructions say for her fob. I just found your instructions odd for a moment because I can’t picture that being in the owner’s manual, and since BMW makes the car then they should have instructions on how to do this. That’s what I meant. 🤓

[@IntegraDIY]

The video I posted is a sketchy hack way, but it’s pretty easy 👍 I’m not sure how it’s done by the instructions in the manual. But I can help search for it online.. And I apologize about my first reply.. I didn’t know it was an honest question, no BMW will never require someone to open a key fob with a razor blade 😅

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.
