Electric car door lock switches are commonplace in modern vehicles for convenience, accessibility, and automation. However, the lock’s electric circuits are susceptible to failure and need to be checked for functionality if any issues arise.
Having car door lock switches are necessary for the security of your vehicle and its contents. That’s why the insurance broker app Jerry has compiled everything you need to know about checking your car door locks.
The exact cost varies between different Land rover models. For example, newer vehicle models are usually made with more expensive materials, so recent or high-end models will cost more, especially if your service requires a part replacement. Use the table below to estimate the cost for your own vehicle.

What is an electric car door lock?

An electronic car door lock is a rocker switch that locks and unlocks the doors of the vehicle when switched on or off.
When the button is pressed, an electrical signal is sent to the door lock actuators to perform the button’s on/off function.
Car door switch buttons are typically located on the interior of the vehicle on each passenger door and act as an electrical anti-theft device.

How do I know if my car door locks are working?

The signs of broken electric car door locks are fairly easy to recognize if you know what to look for.
Watch out for the following symptoms of a malfunctioning locking system:
  • Door locks that function intermittently or switch rapidly may indicate that the electrical system is worn out and unable to send consistent power signals to the car door lock actuators.
  • A broken switch button can impact the functionality of your door locks and may occur as the result of frequent use.
  • Door locks that do not function are indicative of a broken electric circuit within the power switches. When the switch is broken, the power signal cannot be sent to the actuators, and the car door locks cannot work.

How to troubleshoot car door locks

If you suspect your vehicle’s locking system is broken, you can use the following steps to assess the power lock system and identify the cause of the problem.
  • Check the fuses and circuit breakers of the vehicle.
  • Turn the switch to its on and off positions and listen for a click.
  • Remove the power switch panel from the door and assess the voltage using a voltmeter.
  • Inspect the wire that runs from the switch to the fuse panel for any short or open wires.
  • Use a multimeter to check the switch for continuity.
  • Test the power relay to ensure the voltage from the switch is being relayed appropriately.
If your knowledge of vehicle systems is limited, book an appointment with a professional mechanic to assess and repair the problem.
