Question about BMW 3 Series
There is a fuse for the central locking, check the user manual and find the fuse.
If the fuse blows again , then it is one of the actuators in the door, that is shorted and must be replaced.
If the fuse is OK and the central locking still does not work, then there is a switch module.
If that does not work you can also try disconnecting the battery cable for one minute. You will need anti theft code for the stereo afterwards.
The central lock in known for having problems in the 2004-2006 Executive models (eg. E90 , E46). If you have one of those models, step at the nearest dealer and ask if the control module may need replacement.
Check fuse first.
