BMW / Not Start BMW alarm system or the key itself may be the reason why your car won't start.


Try locking and unlocking the car a couple of times then try starting it.

This problem often happens if the key gets wet or is stored in a humid environment.

Don't drop your BMW key in water or let it get wet from the rain. It can stop working. You may think the key is fine but in fact,it is not.

Grab your spare BMW key and test to see if it will start the car.
