Possible Causes For The Issue Of Lights Not Flashing When Locking The Car

Central Locking System Malfunction

  • The central locking system typically controls the lights flashing upon locking your car. 
  • If the system experiences a malfunction, it may affect the operation of the lights. 

Key Fob Battery

  • Another possible cause is a weak or depleted battery in your key fob. 

Programming or Configuration

  • Sometimes, the lights not flashing when locking the car may be due to a programming or configuration issue. 
  • The settings for the lighting system may have some changes or require reprogramming.

Practical Troubleshooting Steps To Overcome The Issue

  • Start by inspecting the bulbs responsible for the flashing lights. Locate the bulbs (usually in the headlights or taillights) and visually examine them for any signs of damage or burnout.
  • Check the fuse visually or use a multimeter to test for continuity. If the fuse is out of condition, replace it with a new fuse of the same rating.
  • Look for any signs of damage, frayed wires, loose connections, or corrosion. If you notice any issues, make sure to consult a professional technician or your vehicle’s service center for further inspection and repairs.
  • Verify if the central locking system is functioning correctly. Use the key fob or the door lock buttons inside the vehicle to lock and unlock the car.
  • A weak or depleted battery might be the culprit if you use a key fob to lock and unlock your vehicle. Replace the battery with a new one, ensuring it is the correct type and adequately installed. Test if the lights start flashing when using the key fob after replacing the battery.
  • Consult your vehicle’s manual or contact a dealership for instructions on how to check and adjust the lighting system’s programming or configuration.
