Disconnect the battery: Open the hood of your Peugeot Partner and locate the negative terminal of the battery. Use a wrench to loosen the nut that holds the negative terminal cable in place and disconnect the cable from the battery.
Wait for a few minutes: This will allow the power to drain from the central locking system.
Reconnect the battery: After a few minutes, reconnect the negative terminal cable to the battery. Tighten the nut that holds the cable in place.
Lock and unlock the doors: Use the key to lock and unlock the doors of your Peugeot Partner manually. This will help to reset the central locking system.
Test the central locking: Try to lock and unlock the doors using the remote key or the central locking button inside the vehicle. If the central locking is working properly, the doors should lock and unlock without any issues.
