Mercedes Driver Door Won T Lock

Opening the driver door while all the other doors were locked would set off the alarm.

Mercedes driver door won t lock.

Got home today and when i wanted to lock the car i realised that it doesn t want to lock at all. 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. Using the key in the driver door lock would lock all doors except for the driver door. The replacement actuator was a mercedes replacement part.

The key fob battery is dead. 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. Turns out i didn t lock the car the day before. Straightening the linkage solved the problem.

I replaced the vacuum element actuator which did not solve the problem. Driver side door won t unlock using remote. This is one of the most common reasons why your car door lock is not working. Just not unlock driver door.

Got to the car today opened the door and the alarm went on. 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. All of the other door lock actuators work.

If your locks arenâ t working replacing the battery in the key fob could solve the issue.
