With modern vehicles, the mechanism is also used for the unlock and lock of the keyless entry as well as a sensor for the alarm system. If you are having problems with either system and have exhausted all other possibilities, the problem is more than likely your latch. This is the perfect solution for those problems. 1 x Front Left Door Lock Actuator 1. Not for vehicles with comfort access or soft close doors. 2.
