- Additional Numbers: N/A
Compatibility And Applications
This lock set is intended for Citroën C2 and C3 vehicles from 2005 onward. It suits vehicles equipped with mechanical locks and standard ignition barrels. When searching, customers often use the product codes 4162FP or 4162EA to find the correct part quickly.
Function
The set replaces the primary locking components: the driver’s door lock secures vehicle access and interfaces with the internal latch and, depending on equipment, the central locking actuator. The fuel filler cap lock prevents unauthorized access to the fuel tank. The ignition barrel houses the mechanical key cylinder and works with the vehicle’s steering lock and immobilizer transponder (if present in the key). Together these components restore mechanical locking and key operation.
Replacement Procedure
- Prepare: Park the vehicle on a flat surface and ensure the ignition is off. For safety when working near the steering column or electrical connectors, disconnect the negative battery terminal.
- Driver’s Door Lock: Remove the inner door card to access the lock unit. Disconnect linkages and electrical connectors (if present), remove mounting bolts and extract the lock mechanism. Install the new lock, reconnect linkages and test mechanical operation before reassembling the door trim.
- Fuel Filler Cap Lock: Open the filler flap, remove any trim or retaining screws, extract the lock cylinder and replace with the new unit. Verify the flap opens and closes smoothly and that the key turns freely.
- Ignition Barrel: Remove steering column covers to access the ignition barrel. In many cases the barrel must be removed by releasing a retaining pin or screw with the steering in the specified position. Fit the new barrel and confirm that the key turns the ignition and that the steering lock engages/disengages correctly.
- Key Transfer/Pairing: If the key contains an immobilizer transponder, additional key programming or pairing may be required to start the engine. Mechanical key cutting may also be necessary if the set is supplied with a key blank.
Installation Recommendations
- Work Cleanly: Protect interior trim and bodywork while removing door panels and column covers.
- Use Proper Tools: Small trim tools, Torx/Phillips drivers and a socket set are typically required. For ignition barrel work, follow the vehicle manufacturer’s procedure for steering lock position to release the barrel safely.
- Lubrication: Lightly lubricate new lock cylinders with graphite or a specialist lock lubricant (avoid wet oils) to ensure smooth operation and long service life.
- Immobilizer Note: If the key contains a transponder, ensure correct immobilizer handling and, if necessary, use authorized diagnostics or locksmith equipment to program keys.
- Professional Assistance: For tasks involving immobilizer programming, complex central locking systems or uncertain procedures, seek a qualified technician with appropriate PSA service tools.
Reason Why The Part Fails Most Often
Locks and ignition barrels commonly fail due to mechanical wear, key wear, corrosion from moisture ingress, dirt accumulation and frozen components in cold climates. Repeated force from misaligned keys or buildup inside the cylinder can break tumblers or cause the key to become stuck. Fuel flap locks often suffer from corrosion and debris because they are exposed to the elements. Electrical failures of central-locking actuators or linkages can give the impression of a faulty lock when the underlying issue is mechanical or electrical elsewhere.
Why Choose This Set
This kit provides the main mechanical lock components and one key, helping workshops and DIY enthusiasts restore security and reliable operation quickly. Use the product codes 4162FP and 4162EA when searching to ensure fast identification. Suitable for professional repair shops and experienced home mechanics looking for a direct replacement for Citroën C2 and C3 models from 2005.
