Mercedes Driver Door Won T Lock

All of the other door lock actuators work.

Mercedes driver door won t lock.

O k what most commonly acts up like this here or fails is the drivers door latch lock itself it has the electronics in it to lock and unlock this door and the electronic actuator built into it can act up or fail like this here with the latch lock itself needing replaced i have seen this fail several times in the past before needing replaced and suspect yours needs replaced. 2010 c300 driver side door lock actuator was not working and door would not lock i replaced actuator and the door now closes and latches but the actuator still does not work. I replaced the vacuum element actuator which did not solve the problem. There are five common reasons why your car door lock is not working.

Straightening the linkage solved the problem. I have tried to lock it using the button on the handle i tried to lock it using the remote i have also tried opening it using the actual key. Turns out i didn t lock the car the day before. Opening the driver door while all the other doors were locked would set off the alarm.

I took out the lock mechanism from the door and upon inspection found that one of the metal linkages was twisted.
