How To Fix Subaru Power Door Lock Problems

Power door locks are an essential part of your Subaru’s safety and convenience features. When they malfunction, it can be both frustrating and concerning. Whether your Subaru's door locks are not working at all, or they are making strange noises, it is important to address the issue promptly to ensure your vehicle is secure and functioning properly. At Empire Subaru, we understand how crucial it is to maintain your Subaru's systems, and in this article, we will guide you through the steps to fix common power door lock problems.

Identifying the Problem

The first step in fixing Subaru power door lock issues is diagnosing the root cause. Several factors can affect the functionality of your power door locks:

• Battery or Fuse Issues: A blown fuse or weak car battery can prevent your power locks from working properly. Check your Subaru’s fuse box and the car battery to ensure they are in good condition.
• Faulty Actuator: The power door lock actuator is the motor responsible for locking and unlocking the doors. If the actuator is malfunctioning, the locks may not respond to the key fob or internal switch.
• Worn-out Wiring or Connections: Over time, wiring can wear down or connections can become loose, preventing the signal from reaching the power locks. Inspect the wiring system to ensure everything is intact.
• Key Fob or Remote Control Issues: Sometimes the problem may not be with the door lock mechanism itself but with the key fob or remote control. If your key fob is damaged or the battery is dead, it can fail to communicate with your Subaru’s door lock system.

At Empire Subaru, we recommend performing a diagnostic check to identify the specific cause of the issue.

Steps to Fix Power Door Lock Problems

Once the issue has been diagnosed, here are the steps to fix common power door lock problems:

• Replace the Fuse: If you find a blown fuse, replacing it is a simple fix. Consult your Subaru’s owner manual to find the correct fuse location and specifications.
• Test and Replace the Actuator: If the actuator is faulty, it will need to be replaced. This may require removing the door panel to access the actuator. Make sure to get a replacement part that is compatible with your Subaru’s model.
• Inspect and Repair Wiring: If you suspect that the wiring is causing the issue, carefully inspect the wires for any signs of wear, cuts, or corrosion. Repair or replace any damaged wiring to restore proper functionality.
• Replace the Key Fob Battery: If your key fob is not working, try replacing the battery first. If the fob is still not functioning, consider getting a replacement key fob or having it reprogrammed by a professional.
