Installation & Replacement
Replacement should be carried out by a qualified mechanic or a competent DIYer. Typical steps include:
- Disconnect the negative battery terminal before starting to prevent short circuits and avoid airbag risks
- Remove steering column covers to access and release the ignition barrel; some models require removal of retaining screws or clips
- Withdraw the old barrel, transfer any electrical connectors or immobiliser components as required and install the new barrel securely
- Replace the fuel-cap lock by removing interior trim around the filler neck, unbolting the lock unit and refitting the new lock
- After mechanical installation, verify that the keys turn smoothly and that the vehicle recognises the keys; transponder keys may require programming
Common Faults And Causes
Lock assemblies commonly fail due to worn tumblers, corrosion from moisture ingress, broken or bent key blades, or general mechanical wear. Symptoms include difficulty turning the key, intermittent starting problems, or inability to lock/unlock the fuel cap.
