BMW Door Lock

Reasons Behind Door Lock Failure in a BMW From Certified Mechanics in Pineville

by Dutch Silverstein December 29, 2020

We’ve come to expect security and safety in all areas of our lives. One of the easiest and most common ways we feel safe is by simply locking things. Before we leave the house, we lock our doors. When we are done using our phones, we lock our screens. In similar fashion, when we are done using our vehicles for the day or are parking at our favorite store, we lock our vehicles.

Being able to lock the doors of your vehicle is a simple way to feel secure; you trust that locking the doors will deter people from trying to break in and keep your valuables, including the car, safe. We might take this function for granted, but when it malfunctions, it can be extremely stressful. It’s important to pay attention to your car and notice when there could be a possible issue that could make your life harder. Here are some common reasons behind door lock failure in your BMW.

Malfunctioning Door Lock Actuator

Door lock actuators are the electronic devices that activate the door locks when you press the lock button. There are a few warning signs that the actuator is going bad on your BMW. When you press the lock button, you may hear strange noises coming from the locks themselves.

Another warning sign is more physical. If you notice your car locking or unlocking even though you never pressed the lock or unlock button on your key fob or in your car, the actuator may be malfunctioning. Fortunately, the actuator does not wear out very easily, but since the locking and unlocking functions are two of the most used on your BMW, these may wear out over time.

Bad Fuses

Since the lock system in your BMW is mostly run through the car’s electrical system, any time there is an issue with the electrical system as a whole, your BMW’s locks may be affected as well. More specifically, the lock system may have an issue with its fuses. To see if your BMW’s fuse box is failing, bring it in to be checked by a professional mechanic. If it needs it, they will replace the blown fuse and restore your locks.

Faulty Key Fob

Key fobs are used in most cars these days. They enhance security and efficiency. However, when they are faulty or malfunctioning, they could cause you to panic. If your BMW is having problems locking, start by checking your key fob. Sometimes the issue isn’t due to faulty internal systems, but because the battery is dead or dying in your BMW’s key fob. This is an easy fix and will save you some anxiety.

Wiring Issues

Another reason your BMW’s locks may be malfunctioning is the wiring in its electrical system. Wiring doesn’t wear out often, but over time and continual use, it can become faulty. The most common sign of wiring issues in inconsistent locking. This means that sometimes your car locks or unlocks when you hit the button and other times it doesn’t so the system is inconsistent. Repairing your BMW’s electrical system will require you to visit your mechanic to have the system looked at and repaired by a mechanic.
