San Jose European Auto Repair Review Ratings250 Reviews

As you own your BMW for an extended period of time, you can expect to have failures in parts as a natural progression of wear and tear. One of the most used components is the door lock. Below you will find out more about what can cause door lock failure and what signs to look for if that has occurred.


Knowing the causes of a failure in the door lock in your BMW is the first step when it comes to trying to figure out the best way to proceed with repairing the door. There are a few common reasons as to why the door lock in your BMW can fail. If you think that it is one of the below causes then it is best to bring your BMW a specialist to have the door lock looked at.


One of the first common causes of door lock failure in your BMW is a faulty key fob. With the advances in technology that are being applied to your BMW today, it is easy to understand how a small car key is able to do so much. We rely on this clicker or fob many times a day. If you begin to have issues with the door not unlocking as it should, the first thing that should be looked at is the key fob. If the battery on the fob is low or if it is completely dead then your door will not unlock. So before you go trying to fix the door lock, the first item to check is the fob and its battery.


In order for the electrical systems to function properly in your BMW, wires need to be set in place and run all throughout your BMW. This includes your door lock. Due to the fact that this is electrical, it requires wires to be free from tearsfrays, or overuse. If you own an older BMW, then it could be time to replace the wires that connect to your door lock. Even if you own a newer BMW, there is always the possibility that there could be faulty wires connected to the door lock. They could become disconnected or frayed over time. The best person to inspect your door locks is a certified BMW technician. This way, you do not risk the chance of electrocution while working on these wires.


Below are 2 of the most common signs of door lock failure in your BMW:


The mechanisms that are used to open your BMW’s door can be a mix of electrical parts and gears. If you hear noises coming from inside of the door that you have not heard before, this could be pointing to door lock failure. These noises could be caused by loose parts moving around unnaturally inside of the door. These loose parts would be an indicator that they are so worn that they need to be replaced, which could be the reason behind the door lock failure.


Another common signs of door lock failure is erratic locking and unlocking. This could leave you and your vehicle and its contents exposed to theft, if you believe you’ve secured your car but the locks erratically unlock due to a wiring failure. This could also be due to a blown fuse. If your BMW’s door is acting in an unusual manner, then it is time to have your BMW serviced.
