5 Most Common Chevy Cruze Door Lock Problems

Door lock problems can be likened to a nightmare. You can either be locked out of your car in an emergency, or not be able to lock your vehicle, making it an easy target for thieves. Unfortunately, door lock parts tend to wear out due to constant wear and tear. This explains why they are to be anticipated. 

There are many culprits that cause Chevy Cruze door lock problems. These include faulty or dead key fob battery, blown fuse, solenoid malfunction, broken power cable, or broken door lock actuator. Once you identify the root cause, you can troubleshoot it accordingly. It can involve replacing the key fob battery, replacing the solenoid, inspecting the door lock actuator and power cable, and replacing a fuse. 

This article highlights the most common door lock problems on the Chevy Cruze and the possible fixes. 

5 Common Chevy Cruze door lock problems 

Chevy Cruze door lock problems can be frustrating. Since the introduction of the remote and automatic system, there have been new problems to be dealt with. These are as outlined below. 

Faulty or dead key fob battery

This should be the first thing you check in case of a malfunctioning door lock system. There are different ways to determine whether the battery is working, dead, or faulty. For one, check to see if it gives consistent results—it could be working intermittently, sometimes not at all.

Another thing is whether you have to over-click your key fob to get it to work. Ideally, one click should be enough, but if you have to click three to four times before you get your car locked, then it has a weak battery. And lastly is the range to get your car locked or unlocked. A shorter range could imply a faulty key fob.

Fix

If you suspect a faulty or dead battery, it is best to confirm your suspicions by testing the battery using a voltmeter. If it is weak, you will have to replace the battery. 

Blown fuse 

A blown or faulty fuse is also to blame when it comes to door lock problems. Your car comes with numerous fuses, each carrying out a different function. It works to convert a large amount of power to a small amount so it can complete a task, like locking and unlocking a door. In case of a blown fuse, it will not be able to convert the power, and in consequence, the task will not be completed.  

Fix 

Firstly, you are required to check that you are dealing with a blown fuse. Locate the fuse box in your Chevy Cruze, usually in the instrument panel on the driver’s side. Then, look for the fuse that corresponds to the door lock system. If blown or faulty, replace it with another of similar amperage.

Solenoid malfunction 

Whenever you press your key fob, it responds by sending a signal to the solenoid inside the car doors. These solenoids then translate the electronic signal to a mechanical action—moving the steel rod, a task that is similarly accomplished by turning a key in the keyhole. 

 Fix 

The solenoid within the door can be accessed by removing the inner door panel. Replace it with a new one. 

Broken power cable or lock actuator 

The door lock system consists of a power cable and lock actuator which all work together to ensure smooth operation of the system. However, in case of a broken lock actuator or power cable, you may experience difficulty operating the system. 

Fix 

To resolve this, you are required to remove the door panel to access the cable plugged into the door lock actuator. This component is responsible for controlling the door lock. Inspect the cable for signs of damage such as a cut or pinch due to the action of the window going up and down. If it is damaged, replace the cable. If the cable is in good condition, the door lock actuator could be the problem. This will require you to replace the existing door lock actuator. 

Electrical problems 

There may also be an underlying electrical issue that causes the system to malfunction. Typically, every electrical component requires a logic board and wire that lead to the power source (battery, in this case). If the logic board is malfunctioning, or the wires are damaged, there may be issues with the system. 

Fix  

You may have to replace the logic board if malfunctioning. Also, inspect the wires for any signs of damage or fraying. This task is best handled by a professional mechanic.

Conclusion 

Traditionally, car door locks used to be simpler. Now, the keyless entry, although it is more convenient, comes with its share of complications. Hopefully, this article has helped break down these complications for you, as well as suggested the course of action to take in case you find yourself in such a situation.
