Why is the BMW key not working?
1 Answers
BMW key not working is caused by insufficient battery power in the key, and the key battery needs to be replaced as soon as possible. Car key lifespan: The battery in a car key generally lasts about two years. When the key battery power is too low, it will affect daily locking/unlocking and the normal starting of the vehicle. When the car key is unresponsive: Therefore, when the vehicle indicates low key battery power, or the remote control distance becomes shorter or less responsive, it may be due to low key battery power. In severe cases, the BATTERY (BATT) warning light on the instrument cluster will illuminate, at which point the key battery must be replaced.
