If your power door locks are not working, it may be due to an electrical, mechanical, or control system fault. Power door locks provide convenience and security, and when they stop functioning, it can leave your car vulnerable or make it difficult to enter or exit. An inspection will identify whether the issue lies with the switch, actuator, wiring, or central locking system.

What does it mean if the power door locks are not working?

This means the system that electronically controls your door locks is failing. The problem could be isolated to one door or affect all doors, depending on the fault.

Common causes of power door lock failure

• Blown fuse or faulty relay in the locking circuit
• Failed door lock actuator (motor inside the door)
• Faulty door lock switch
• Broken or damaged wiring inside the door or body harness
• Faulty central locking or body control module
• Key fob or remote transmitter failure

Why do you need to fix this problem quickly?

Without functioning power locks, your vehicle may be less secure and more difficult to use. It also poses a safety risk if doors cannot be unlocked quickly in an emergency.

How do you know when to get it checked?

You should book an inspection if:

• One or more doors won’t lock or unlock with the switch or remote
• You hear clicking but the lock doesn’t engage
• The locks work intermittently
• The key fob works for other features but not for locking
• All power locks stop working at once

What happens during an assessment?

A mechanic will:

1. Test the power lock switch and remote key fob
2. Check fuses, relays, and wiring for faults
3. Inspect the door lock actuators for operation
4. Test the central locking or body control module
5. Recommend actuator, switch, or wiring replacement if necessary

How much does it cost to fix?

Costs vary depending on the fault. Fuse or relay replacement may cost $80–$150. A single door lock actuator replacement typically costs $250–$500. Central locking module repairs may cost $400–$1,000+.

Is it unsafe to drive with faulty power door locks?

Yes. While the car may still be drivable, faulty locks reduce security and may prevent doors from opening in an emergency. The issue should be inspected and repaired promptly.
