Description
Product Overview
Original PSA tailgate release lock designed for Citroën C1 and Peugeot 107 (up to 2013). This unit secures the rear tailgate/boot lid and provides electric unlocking via the central locking system or remote control. It is suitable as a direct replacement when the original lock fails to click, does not respond to the remote, or does not hold the tailgate closed.
Fitment And Installation
Compatible Models: Citroën C1 (approx. 2005–2013) and Peugeot 107 (approx. 2005–2013); fits all trims and engine variants of the first generation. Installation is straightforward and requires no ECU programming: remove the inner plastic trim of the tailgate, disconnect the electrical connector, release the Torx screws securing the lock, remove the old unit and fit the replacement. Reconnect the wiring, check function, and adjust the striker/latch alignment for smooth closing.
Symptoms And Common Causes
Typical failure signs include: the tailgate will not open with the button or remote, a weak or absent “click” from the actuator, the tailgate fails to latch or stays unlocked unless pressed firmly. Common causes are actuator or latch wear, moisture ingress into the mechanism, corrosion of the electrical connector, or broken wires in the tailgate wiring harness. Replacing the lock usually restores full electric unlocking and reliable latching.
Maintenance And Tips
When replacing the lock, inspect the wiring in the tailgate hinge area for broken or pinched conductors, clean and protect connectors against corrosion, and lubricate the latch striker lightly to prevent premature wear. Verify alignment of the striker post to avoid excessive load on the actuator and uneven closing.
