How to open Mini Cooper 2005 R50 key fob and replace battery. Key fob repair. PLEASE SUBSCRIBE 

Without watching this video i would have spent $250-$300 thanks for sharing this. All it cost me is about less than $25 went to Frys to buy the tools and battery where he posted to buy. And it works. Honestly i never touch this all tools before but this video helps me a lot. I save this video Thanks :)

Following your video I just replaced both batteries in my mini 2007. Easy job once I managed to open the keys. Thanks for your help. A successful project.

Strong work. Thank you Karp.

Worked like a charm! Thanks!

So precise and clear, will save myself £165 and do this myself too! Thankyou for your help

We had the same problem. Battery in the old mini key was dead. So i bought a battery on ebay, unsolderded the old one and put in the new one same as you and it just works like a charm :) TOP thanks from BELGIUM ;)

Cheers mate - worked a treat!

Thank you very much . Very helpful video. I just received the soldering kit . I did exactly as you said. And guess what. It worked bro. I’ve saved a lot of money. I really appreciate it man 👍🏻👍🏻👍🏻

Spent $6 get my things done, thanks for sharing!

Great video and very helpful.

Very helpful video. Thanks so much

Thank you so much for this video! Super helpful to see this process from start to finish-- and thank you for naming the battery type! Panasonic VL2020. Finding 90º VL2020s in the American online marketplaces is near impossible; I opted to go for the more readily available Panasonic ML2020, which from what I've seen thus far appears to be a slightly higher capacity version of the same battery. They're also cheaper!

Many thanks for this🤓👍

Thank you !!

Thank you 🙏

Thank you for this video. I've never soldered before so I'm worried about that bit, but I'm going to give this a try. Worse thing that can happen is it doesn't work and I still can't use the remote. Will update after I try.

Thank you very much

My coopz 2008 key went dead and went to the dealer and will cost me $250 for the whole new one. Cant afford and its been almost a year now. Thanks for sharing this hopefully I can find the battery and see if I can fix it. Thanks. This is great video.

Great vid thanks but you really should have used the flux which prevents oxidation.

Great got my key didn't even know the battery

good video, I'm going to replace both batteries in my Mini 2007 key fob. I'll be sure to let you know how it all goes.

Nice

thanks

Keep me posted. Or you can check the other video linked to this one, where I fix the broken button. :)

Actually! I have a 2005 Mini Cooper R52 Convertible and the keyfob self chargers. I took it apart and realized that the “contact” inside became lose, so 99% if you think you lost batt charge in you key fob? Most likely you didn’t! Check it out. I had my Tech solder back on and walla it works👏👏👏👍👍

This saved me getting a new key although I found the cheap replacement keys off ebay have internals that exactly matched the internal size of the original key so rather than soldering in a new battery I just changed the internals (I found syncing they internals to my car with 4 key turns nearly on then hold unlock button then lock button 3 times worked for me). The price difference between the battery and a cheap chinese replica key was not much.

Thanks very useful

just opened mine, the solder was broken so i put a bit of plastic inside to hold the battery tight and now it works fine,

Hey man, do you know if the battery is actually rechargeable? Because I do not see anywhere on the circuit board where the key makes contact with the board to actually charge the battery itself. How does the key recharge the battery? Can I buy a battery that is actually already charged? Also, can you provide a link to the battery you ordered, I am finding the right battery, but it has the wrong connector tabs on it. Thanks for your help!

could you put a link where you got that battery? I can't find it anywhere. thanks

What is he using in the push tube thing when he de soldier the battery?

Looks like you could bend those tabs over to secure it.

I think this video could have been shortened to 2 minutes. Open the key, replace battery, tell me what battery size.

we have to do the same. After replacement the key didnt work. Maybe it has to charge some time!? Or is there a procedere - key lost codes ect?

I need battery

Where did you get the battery from?

Mmmmmmm.... mmmmm...... AAAAAAHHHHHH OPEN THE DAMN BATTERY. 😂

Car will cycle the locks after several attempts are recoding it but the fob doesn't work afterwards. I don't know what's wrong with this car.

I just got a Mini Cooper 2005 and my key-fob is okay so far, however after seeing this video I can’t believe how stupid BMW is for making it so hard to replace the battery in their Mini Cooper key fob.🤬🤬😡😡Ot really p’os me. To me it’s another way that Mini and BMW rips people off, cause for the dealer to do this according to this guy it costs like $180.😡🤬

They only make it complicated so people can spend money! 😂 car manufacturers just find ways to make it difficult for people to fix themselves! 😄

Just stop. DO NOT OPEN YOUR KEY WITH A STANLEY KNIFE! You will very likely cut your hands and slice off tiny components off of your circuit board rendering your key useless. Notice how Karp doesn't even show the key being cut open. If you must do this yourself please go in carefully from the top with a tiny screwdriver and go down the sides of the shell where it's sealed, perpendicular to the body of the key if you will. If you go down one side they will usually just pop open at that point. I do MINI key repair on the side and have seen many keys come through having been damaged while being cut open. Some can be repaired, some can't. You have been cautioned.

Nvm I googled it it’s a pump

Didn’t work for me...followed instructions exactly. Anyone else have problems?

Are kidding me? is cheaper to change the car!!

Way too long, just show how in 2 minutes, do some editing.

Doesn't work. Don't try it

Quite possibly the worse design ever!!

This car is headache! Stay away
