Chevy Cruze: Auto Lock Problems

Automatic lock problems can be a nightmare. The parts that operate your automatic locks wear out due to constant wear and tear. Below is how to find out what is wrong with your Chevy Cruze auto locks.


Key Fob Battery is Dead/Faulty

The first thing to check when you cannot unlock or lock your Chevy Cruze is to check your key fob battery. To determine if your key fob battery is dead or faulty, ask yourself the following questions:

  1. Does it provide inconsistent results? Sometimes it works great; other times, not at all.
  2. Do you over-click your key fob? Cars will usually lock with one click, but you may click your car 3-4 times to ensure it is locked.
  3. Does it have a shorter range to lock/unlock the car? You may be able to lock your car from clear across a parking lot, but now you have to be right next to the car.

If you believe your key fob battery is dead/faulty, you can test the strength of your battery with a Voltmeter. You will need to remove the battery from your key fob and test its strength. You can also learn how to replace the key fob battery.

A Blown Fuse

A faulty or blown fuse is common for any vehicle. Your car has multiple fuses, each completing a different function, but a fuse takes a large amount of power and converts it to a small amount to complete a task, such as unlocking or locking your door. If a fuse is blown, it can no longer convert the required power, so it will not complete the task.

To determine if you have a blown fuse you can open your fuse box located in the instrument panel (on the driver’s side), behind, and under the cover to the left of the steering wheel.

Broken Power Cable/Lock Actuator

  1. Remove the door panel to reveal the cable plugged into the door lock actuator. This controls the door lock.
  2. First, check to see if the cable has been pinched or cut by the action of the window going up and down. If damaged, replace the cable.
  3. If the cable looks good, the door lock actuator may be the problem. You will need to order and replace the existing door lock actuator.
  4. Reinstall the door panel while you wait for your part to arrive.

Reset the Central Locking System

If all items above have been checked and are operational, try resetting your central locking system.

  1. Press and hold down 🔽 the LOCK button on the key fob for one second.
  2. Insert the key in the ignition with the lights off.
  3. Turn the key to the ON position.
  4. Your central locking door switch is reset.
