Replacement Key Fob Battery VL2020 90 Degree Pins Compatible with BMW 1 3 5 6 7 Series E90 E92 E93 Keyless Remote Start

Works perfectly, BMW dealer had said the battery in key fob is not replaceable and I had to pay $400 for a new key. I fixed both key fobs with $12

Mala calidad la bateria solo funciono 2 dias y se quedo sin carga, parece que es demasiado vieja, la tubieron almacenada por mucho tiempo quiza .No la recomiendo

Opening the original case requires careful cutting (to prevent injury) and prying (to prevent damaging the PCB board) but the soldering work is easy. The battery fits well, only the legs are long and needed to be bent in place before soldering. The remote works right after.
