The door of any car, not just a BMW, might be the most sophisticated part of the car. Unless you purchase a completely new BMW, the odds are that there might be something wrong with the door locks of your BMW. In fact, the door is the place on the car that is most frequently broken and thus needs a repair. Besides door handles, window regulators, mirror switches and the window glass itself, you have the BMW door locks. If you want to work on your car door, here is what you need to do.
The first thing you should be concerned with is the panel of the door. This usually needs to be removed in order to get inside of the door. You will need a certain amount of force to remove the panel from the door. Often it is attached to the door with 11 plastic clips.
Now that you have removed the door panel, you have access to the inside of the BMW door. Just to make sure everything is in order, it is advisable to check all of the components of the door to make sure everything is working correctly. For example, if the door-mounted speakers are not working, now you have unique chance to do something about it before you put the panel back in its place.
The door lock can also get broken. For example, BMW drivers have experienced a scenario when the doors would lock but they would not unlock. This can either be the case for all of the doors or only for a single one. In any event, there are ways to repair it on your own. Something might be wrong with the door lock actuator which is located within the door and which you can access upon removing the door panel. In most cases you will need a chisel or a similar tool to take the actuator out of the door because it is firmly attached to it. You might need a new actuator or the current one may need a repair. Whatever the case is, if you are unable to diagnose the state of the actuator yourself, bring it to the dealer and he/she will help you out.
Bringing the door back to its original state is rather simple. It is recommended you use new plastic clips to attach the door panel to the door. Getting new ones is inexpensive and if you used the old ones, chances are they could break soon.
