This used BMW Lock/Unlock Door Switch (OEM 9386780) is a genuine factory part, removed from a donor vehicle for the front left door. Also known as a door lock switch, it controls central locking from that position. When it fails, the switch may become unresponsive or erratic, preventing you from locking or unlocking that door. This particular switch is engineered for BMW X3 and X4 models, including the wide range of turbocharged four- and six-cylinder engines those vehicles use. A direct replacement for the original unit.
