BMW Door Lock Failure

Reasons For Door Lock Failure in Your BMW

Post on July 13, 2019 by

The BMW brand is known for its undeniable luxury, sleek design, and strong performance. Car enthusiasts across the nation fall in love with the way the engine purrs and tires roll. However, part of being on the front line of innovative technology compared to other vehicles, is that technology can fail as it is still being perfected. Some of these issues are major while others are not, but are down right frustrating.

Let’s consider the latter; Imagine rushing to work one busy morning with little to no time to spare. You reach for that glossy BMW door only to realize you’ve been locked out. As much as you pull and tug, you can’t seem to wiggle your way into your own vehicle. Unfortunately, door lock failures can be a common issue BMW owners face. Like any vehicle malfunction, each is individual and needs to be diagnosed as there are several different possibilities that can cause a malfunction:

Damaged Door Lock Actuator

The actuator is an advanced part of your BMW. It isn’t strictly mechanical latches; it communicates with your key and handle, is the middle man between the lock cylinder and the control unit. It also has double locking gears from the inside and outside as well as hall position sensors internally. When an actuator faults, it can be manageable and intermittent, or it can make entering your car difficult to impossible, even locking you out. Therefore, it is always best to be proactive and bring your vehicle to the shop to get door lock actuators replaced before they get worse.

Malfunctioning Fuses & Electrical Network Problems

BMWs are wired very differently than domestic vehicles; problems in another sub system or even fuses in a shared system can cause faults in another system such as the door locks. This is why it is imperative that your BMW go to a professional, and not a regular repair shop. You will always save the most money taking your vehicle to a professional first.

Faulty Key Fob

If your key fob is damaged or needs replacement, the likelihood of getting locked out of your vehicle is heightened. While some fobs have serviceable batteries and removable mechanical keys, others do not. Furthermore, there is a minefield of misinformation online about BMW key fobs. In the event a fob needs to be replaced, the ONLY place anyone can order a key that will correctly function from is a BMW dealer, period. Again, this is why it is imperative to take your vehicle to a professional specialized shop.

Control Modules

A control module failure can cause “ghost” issues with your locking system that sometimes exhibit and sometimes do not. These can be difficult to isolate and diagnose and they are the most expensive components in the system. Control units also need to be programmed which further adds cost to repair and can sometimes be VIN specific. Therefore, it is important it is diagnosed accurately with confidence.

How to Avoid Major Failures:

Although issues are often due to chance, there are a few things you can do to avoid issues and protect your investment for years to come. One of the best practices is to pay attention to small changes in the way your BMW functions and be proactive about getting it in the shop if you believe it is malfunctioning.

Second, take your vehicle in regularly for oil changes; we recommend 4 months if you drive your vehicle often and 6 months at minimum if you do not. While it is crucial to change your oil this often contrary to BMW factory maintenance intervals, that is a conversation for another blog!

What we will say here is part of why it is important to take your vehicle in at least twice a year is so it gets regularly inspected and you can be made aware of developing issues you would not otherwise see. This way, you can be pro active and fix a minor concern before it becomes a major concern. You can also budget and plan out your vehicles needs when you know what to expect rather than be hit with a large bill at once.

Lastly, always make sure the mechanic you are visiting understands how to work on your BMW and specializes in the vehicle. There are several shops who claim they know how to service German automobiles but do not have the experience or tools necessary. Do your research and make sure you’re choosing the best mechanic for your car.
