How to replace the E65 7-Series (2001-2008) key fob remote battery with non-comfort access

Replacing the battery in a non-comfort access remote key fob requires a bit more work. These batteries are rechargeable and will usually last longer then the comfort access keys as they are charged when the key is inserted into the car dash. If this battery does die, you’ll need to pry apart the key, unsolder two points on the circuit board and re-solder a new rechargeable battery, the VL2020, to the board.
