Comment réinitialiser la centralisation lorsque la clé ne fonctionne plus sur Peugeot/Citroën

Introduction

This tutorial provides a step-by-step guide on how to reset the central locking system for Peugeot and Citroën vehicles when the key is not functioning. It’s a common issue that can occur due to various reasons, such as battery failure or key synchronization problems. By following these steps, you can troubleshoot and potentially resolve the issue yourself.

Step 1: Check the Key Battery

• Start by examining the battery in your key fob.
• If the key fob is not responding, replace the battery.
• To change the battery:
  • Open the key fob using a flathead screwdriver.
  • Remove the old battery and insert a new one, ensuring it is positioned correctly.
  • Reassemble the key fob and test it again.

Step 2: Re-synchronize the Key with the Vehicle

If the key battery replacement does not resolve the issue, you may need to re-synchronize the key with your vehicle.

• Follow these steps to re-synchronize:
  • Enter the vehicle and close all doors.
  • Insert the key into the ignition and turn it to the "On" position, but do not start the engine.
  • Leave the key in this position for about 10 seconds.
  • Turn the key back to the "Off" position and remove it.
  • Test the key to see if it now operates the central locking system.

Step 3: Perform a Manual Reset of the Central Locking System

If the key still does not work, you may need to reset the central locking system manually.

• Here’s how to do it:
  • Lock and unlock the driver's door using the physical key.
  • Open and close the driver's door.
  • Try using the key fob again to see if the central locking has been restored.

Step 4: Check for Faults in the Vehicle’s Central Locking System

If none of the above steps work, the issue may lie within the vehicle's central locking system itself.

• Inspect the following:
  • Look for blown fuses related to the central locking system in the fuse box.
  • Check for any visible damage to wiring or connectors.
  • If you suspect a fault, consider consulting a professional technician for further diagnosis.
