Description
Original used PSA tailgate release lock designed for Citroën C1 and Peugeot 107 models produced up to 2013. This OEM unit (part number 871988) secures the tailgate/boot lid and operates the electrical release for the rear glass or boot lid, restoring reliable opening and locking function.
Suitable for professional workshops and home mechanics, the part is a direct-fit replacement that typically does not require programming. Typical replacement steps: remove the inner plastic trim of the tailgate, disconnect the electrical connector, and remove the Torx screws securing the lock. While replacing, inspect the wiring flex harness at the tailgate hinge for cracked or broken conductors and check the striker alignment to ensure smooth closure.
Common failure symptoms include: tailgate does not open with the remote or interior button, weak or no audible ‘click’ from the actuator, tailgate fails to lock after closing, or the latch only secures when pressed hard. Typical causes are actuator or latch wear, moisture ingress in the mechanism, corrosion of the connector, or broken wires in the hinge harness. Replacing the lock usually resolves these issues and restores reliable electrical release and locking.
