- In this video I will show you how to replace the internal battery in a non-comfort access BMW key fob. This remote uses a VL2020 battery with the battery leads spaced 90 degrees apart. I found mine on Ebay for searching for VL2020 BMW specific version for about $12. To get into the remote we must cut it in half this requires some force but be gentle to not stab deep into the remote with your blade so that you do not damage the circuit board inside.
Let me know if you have any questions in a comment down below

Many thanks, I found this very helpful. Getting into the old fob was a real pain, and when I had transferred the innards and new battery into a new case, it didn't work at first. I tried the new fob in the ignition to see whether I could at least start the car. This was successful, and afterwards the fob worked fine at unlocking and locking the doors as well. I hope this helps anyone who has problems at first with their new battery.
Thanks to poster for the quality video. Quick heads up to everyone from an electrical engineer - the VL 2020 is a low-current rechargeable lithium battery. BMW recharges the fob battery while it’s in ignition. Replacing VL2020 with CR2025, BR2025 and similar will function as a stopgap measure- but in the longer term you stand to damage the recharging circuit on fob circuit boards and/or cause battery leakage if you don’t put a VL2020 in the fob. CR, BL battery materials don’t like having electric current jammed into them…
Quality BMW info
Thanks alot
How BMW make fib key like that??!! WTF! Who create that!
One of my components is defective. Can someone tell me which component is between the battery and the transponder? Directly above the quartz, in the middle of the board. What kind of component is this (resistor, etc.) or what does it say?
you got a real Wayne from Letterkenny vibe. did you have a key battery warning on the dash before it was dead?
I have the same car withe the fox red leather
The E87 also has this keyfob.
Fun fact: BMW won't do this for you. You have to buy a new key for around €360
Hey there mate, I accidentally bought vl2030 instead of vl2020. The vl2030 is slightly bigger but you can still fit it in. Would it still work?
hello is there a positive and negative point before i solder
I’m just wondering but can you put a key fob with comfort access onto a key fob that originally isn’t supposed to have comfort access? I have the same one on the video pls lmk
tell me can u cut the green chip becouse its not geting fit in cover ?
Hey you don't need an exact vl2020 battery to make it work you can instead even use any cheap 3V battery which will work
Link to battery?
How long did the battery last?
How would you do it without a solder sucker
Yeah…I’ll just buy the $200 key since I work for a car dealer ship and get cost lol…what a job
