Why Will A Car Constantly Lock And Unlock Without The Driver’s Command?

There are several common reasons your car’s auto-lock system is malfunctioning.

The Actuator Might Be Faulty

The system relies on an actuator to convert the electrical signal from the remote control to mechanical action. This issue is common among central locking systems, even the least complex ones.

Defective Door Sensors

If the door sensors wear out you will have to replace them. Continued use of the faulty sensors will result in more frustration.

The Wiring System Might Be causing problems

Some wires connecting the system to the doors might be exposed and worn out. If these wires come into contact with the car’s body they could cause a malfunction in the auto-lock system.

Dust might penetrate the system’s core

This will hinder the effective movement of the locks. Signal relaying will be disrupted causing the system to misbehave.

The key might be faulty

Cars doors will unexpectedly open and close if there is poor communication between the central locking system and the key. This could happen if one of the buttons is stuck or the battery is low. The doors might even unlock on the highway.

Do Keyless Entry Automatically Lock?

Yes, if the key is more than 15 meters away from the car, it automatically locks up. This feature is meant to secure the car even when the driver leaves without locking the doors.

How do I stop my car from locking automatically?

The auto-lock feature is designed to improve your car ownership experience but you might for some reason want it deactivated. You can follow this procedure.

  • Insert the key and turn it on
  • Press unlock three times
  • Turn off the car
  • Turn it on again
  • The horn will beep to confirm the programming mode
