why are my Volkswagen Golf MK7 (2015-2019) power locks not working

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, flat-head screwdriver, socket set.
• Ensure the vehicle is in a safe and well-ventilated area. Disconnect the battery to avoid electrical shock.

2. Check and Replace the Fuse

• Locate the fuse box (typically under the dashboard or in the engine compartment).
• Identify the fuse linked to the central locking system using the fuse diagram.
• Remove the fuse using a fuse puller or flat-head screwdriver.
• Inspect the fuse; if blown, replace it with a new fuse of the same amperage (usually 15-20A).
• Reconnect the battery and test the power locks.

3. Test and Replace the Key Fob Battery

• Open the key fob using a flat-head screwdriver, being careful not to damage the casing.
• Remove the old battery and check the orientation of the new battery.
• Replace it with a new battery (typically CR2032) and reassemble the fob.
• Test the key fob functionality.

4. Inspect and Repair Wiring

• Remove the door panel using a socket set to access the internal components.
• Inspect the wiring harness connected to the lock actuators for any frayed wires or loose connections.
• Repair any damaged wires or replace connectors as necessary.
• Reassemble the door panel securely.

5. Replace Lock Actuator (if necessary)

• If the actuators are found to be faulty, remove the locking mechanism from the door.
• Disconnect the wiring harness from the actuator.
• Replace with a new lock actuator, ensuring proper orientation and connection.
• Reassemble the door panel and test the locks.
