Door lock question?

[///Bimmerfan]

My locks including driver, pass door and trunk have to be locked by hand I cant just go to the trunk and lock them all. It worked before but now I have to lock my doors and trunk with the key.

sounds like you need a central locking module

If the locks will lock and unlock from any combination of the three locks that control the central locking module, all is well.

If they don't all lock or unlock, it is either a bad actuator or bad wiring.
