What The Kit Contains
The set includes: one ignition barrel (switch), two door lock cylinders and one fuel-flap lock cylinder. Note: The rear tailgate lock in this particular set is seized/rusted and may require freeing or replacement if it cannot be recovered.
Function And Failure Modes
Door and fuel-flap cylinders provide physical locking and, when connected, allow central-locking actuators to operate. The ignition barrel houses the mechanical key interface and works with the vehicle immobiliser system via the key transponder. Typical causes of failure include:
- Corrosion and water ingress, especially on tailgate and exterior locks.
- Wear of tumblers and key grooves after long service life or heavy use.
- Broken or worn linkage/actuators preventing lock operation.
- Debris or rust causing lock seizure (common on rear tailgate locks).
- Ignition barrel wear, making key turn difficult or causing intermittent contact with the ignition switch.
Replacement Procedure (General Guidance)
- Safety First: Always disconnect the vehicle battery before starting to avoid short circuits and to protect electronic systems.
- Door Lock Replacement: Remove the interior door trim to access the lock cylinder. Disconnect the lock rod/linkage and any electrical connector for central locking actuators. Remove the retaining clip or screw, withdraw the old cylinder and install the new one. Reconnect linkage and test lock operation before reassembling the trim.
- Ignition Barrel Replacement: Remove steering column covers to access the ignition barrel. With the key in the appropriate position, remove the retaining screw or release pin and withdraw the barrel. Install the new barrel, ensuring mechanical alignment and smooth key operation. Reassemble covers.
- Fuel-Flap Lock Replacement: Access the fuel-flap lock from inside the fuel filler area or trunk depending on body version. Remove fasteners, disconnect linkages and replace the cylinder. Test fuel-flap locking/unlocking.
- Final Steps: Cut keys to match the new cylinders. If the keys include transponders, program the transponder to the vehicle immobiliser (see Programming Note below). Verify central locking, door and ignition function before finishing.
Programming Note
Keys With Transponder Chips Require Cutting And Immobiliser Programming. Programming Can Be Performed With PSA Diagnostic Tools (DiagBox/Lexia) Or By A Qualified Automotive Locksmith Equipped For PSA Vehicles.
Installation Recommendations
- Use graphite or dry-type lock lubricant when installing; avoid oil-based lubricants that attract dirt.
- Replace worn or corroded linkages and fasteners to ensure reliable operation after cylinder replacement.
- Check and, if necessary, treat surrounding sheet metal and drainage paths to prevent future corrosion.
- Test All Functions Before Reassembly: central locking, manual locking, ignition start and fuel-flap release.
Reason Why The Part Most Commonly Fails
Exterior locks—especially the rear tailgate—are most commonly rendered inoperative by corrosion and water ingress that seize tumblers or rust internal components. Interior wear from repeated use, key damage, and actuator/linkage failures also contribute to lock malfunction. Ignition barrels fail from mechanical wear or contamination, making key insertion or rotation difficult and sometimes causing intermittent starting issues.
Who Should Install This Kit
Suitable For Experienced DIYers And Professional Mechanics. For Key Cutting And Immobiliser Programming, Use Workshop Equipment Or A Specialist Locksmith To Ensure Correct And Secure Operation.
