Used OEM BMW door latch and lock actuator, OEM part number 9492091, formerly installed in a donor vehicle. This front left (driver-side) actuator controls the door's locking and latching mechanism on BMW X3 and X4 models. When the actuator fails, you may experience a door that won't lock or unlock remotely, or the latch may stick, preventing the door from closing securely. This is not a safety-critical component, so a qualified technician is not required for replacement.
