Description
High-quality ignition lock assembly with one key for the Citroën Xsara Picasso. Supplied as a set that includes the ignition switch/barrel, one key and the fuel filler cap, delivered under part number 4162HK. This unit is intended for PSA platform vehicles (Citroën/Peugeot) and is a common replacement when the original lock becomes worn or inoperable.
Why choose this part: The ignition lock is a wear item that endures constant mechanical use and occasional exposure to dirt and moisture. Replacing a faulty lock restores reliable key operation, steering lock function and ignition switching. The included fuel filler cap simplifies refitting and reduces the need for separate ordering.
Common symptoms and causes:
- Key turns hard or becomes stuck — typically caused by worn tumblers or a fatigued key blade.
- Ignition does not switch to accessories or start position — electrical contacts within the switch can fail after many cycles.
- Intermittent loss of electrical circuits (radio, dashboard lights) when turning the key — often due to worn contacts or corrosion.
- Missing or damaged key — replacement key is included to restore secure operation.
Replacement overview (for professional mechanics and competent DIYers): Always consult a workshop manual for vehicle-specific instructions. Typical replacement steps:
- Disconnect the negative battery terminal to prevent short circuits and immobiliser issues.
- Remove the steering column trim panels to access the ignition unit.
- Disconnect electrical connectors and release any retaining clips or screws securing the ignition switch and barrel.
- Withdraw the old unit and fit the replacement assembly, ensuring the mechanical alignment and connector seating are correct.
- Reassemble the column trim, reconnect the battery and check all functions.
- Note: On PSA vehicles an immobiliser or key synchronisation procedure may be required for the new key to start the engine — have diagnostic equipment available if needed.
Compatibility and searchability: This part is commonly searched by the product code 4162HK. It is primarily intended for the Citroën Xsara Picasso on the PSA platform. Use the part number 4162HK when searching catalogues or ordering to ensure correct fitment.
Practical advice: Inspect the key blade for wear and the switch connectors for corrosion during replacement. If electrical faults persist after installing the new lock, check wiring continuity and the ignition switch connector pins. For immobiliser or programming tasks, consult a diagnostic tool or a specialist workshop.
