Replacement And Installation Notes
General guidance for replacing the ignition switch and door lock cylinders:
- Disconnect the vehicle battery before beginning any work on the ignition to avoid electrical hazards and immobilizer complications.
- Ignition switch: remove steering column trim panels, locate the lock barrel retaining clip or screw, remove the old cylinder and install the replacement. Reassemble trims and test key rotation and starter engagement.
- Door lock cylinders: remove the inner door trim to access the lock mechanism, disconnect linkages, unfasten retaining bolts or clips, withdraw the old cylinder and fit the new one. Reattach linkages and test locking and unlocking functions.
- Fuel flap lock: access via exterior or interior service point depending on model; replace cylinder and confirm flap latches correctly.
- After mechanical installation, use your original remote and immobilizer/transponder chip to ensure the engine will start and central locking/remotes function as before.
Common Causes Of Failure
Lock cylinders and ignition barrels wear out due to metal fatigue, key wear, corrosion from moisture ingress, and accumulated dirt. Symptoms include stiff key operation, intermittent contact in the ignition, key jamming, or door locks that do not turn smoothly. Regular lubrication and inspection can extend service life, but replacement is the long-term solution when mechanical wear is present.
Why Choose This Set
This kit provides the mechanical components needed to restore locking function across the driver and passenger doors, fuel flap and ignition barrel. It is a practical choice when keys are duplicated or when lock cylinders show wear. Note that electronic immobilizer components are not supplied and must be reused from your vehicle to maintain security and engine start capability.
