Mail-In BMW Diamond Key Battery Replacement Service
Got a BMW key with a weak or dead battery?
This service is for you
Mail us your key and we’ll replace the VL2020 battery, move everything into a new shell and include the laser cutting service.
Why spend over $250 on a new key when only the battery needs replacing? After ordering we will email or text our shipping address the same business day
We do not recommend this service if you do not have a 2nd key or outside the US
