Reset central locking? Security and key not working..
 

A 2nd issue I've been having.

My key, no longer works. It only turns the car on and off.

I can no longer turn the door to lock or unlock the car.

I've been parking it unlocked.

The trunk opens at times.

The interior lights no longer turn on when you enter the car.

The car alarm flashing light does not flash.

Key in center console does not work. Hazard light key DOES work.

I assume this is something to do with the central locking. My brother had someone tell him its a battery problem? The car has 248100 km on the original battery. But I hear BMW batteries are almost never the issue in electrical problems?

Any advice is appreciated.

Check all central locking fuse. One my friend had the same problem then it turned to be one of fuses.

Try your spare key or your wallet key.

did i read it right? BMW batteries are almost never an issue in electrical problems???

could it be that the OP meant : almost ALWAYS an issue in electrical problems?

i thought this was covered so many times that everyone is onboard - clearly, i was wrong...
