How to fix: Mercedes Lock Failure

Many people dream of owning a Mercedes-Benz. They’re known for being high-end, beautiful and reliable cars, so it’s important to maintain them once you’ve bought one. Even if it’s something minor, you’ll want it fixed as soon as possible.

Everyone wants their car to be in the best condition to make their life easier, regardless of the type of car they have. When you have a nicer, more luxurious car, you expect it to perform even better, and Mercedes is known for doing just that. Even well-built, attractive cars like Mercedes, are susceptible to real-world issues, and the vacuum door lock is one of them.

Potential Causes

  • The actuator is the part of your car that controls the actual door locks. A leaking actuator is one of the most common causes of vacuum door lock failure.
  • Vacuum pump failure. This important part creates a vacuum that causes the lock mechanisms to move. When it fails, the door lock will not function properly.

Signs & Symptoms

Just because you’re aware that this problem could happen doesn’t mean that you know how to find it, or that you’ll know what to look for when it happens. The door locks are unlikely to stop working at once; rather, the doors will begin to fail one by one. 

This means that the passenger door can stop working before the driver’s side. The fact that one door stops working is a sign that the door locks have started to age or another damage has occurred, and it might be a good time to take the car to a trusted locksmith before the rest of the doors become problematic.

Since actuators are expensive to replace, double-check that the broken part is the vacuum door lock. A locksmith should be able to answer this question if in doubt. There are methods of checking yourself, but if you’re not sure you can do it properly, you should seek professional help.

How To Fix It

Calling a locksmith is probably your best bet on solving the problem, but you can also try to fix it yourself. It requires you to open the bonnet and disconnect the vacuum’s three main lines. If you can blow and suck the air out of each of the lines, the line is still good; if you can’t blow and suck, the line is shot and needs to be replaced.
