Description
Description
This ignition barrel with two wafers is designed for Citroën C1 and Peugeot 107 models and corresponds to product code 4162FK. It replaces the lock cylinder that allows key insertion, selects ignition positions (accessory, on, start) and secures the steering column. The unit is intended as a direct-fit replacement for vehicles in the PSA family where this part number is specified.
Features and Benefits
- Direct-fit replacement for Citroën C1 and Peugeot 107 (product code 4162FK).
- Includes two wafers (tumblers) to match the vehicle’s locking mechanism.
- Restores smooth key operation and reliable ignition switching.
- Suitable for professional workshops and competent DIY mechanics.
How To Replace
General replacement steps for a steering column ignition barrel:
- Disconnect the negative battery terminal before starting to prevent electrical faults and airbag deployment hazards.
- Remove the steering column covers to access the ignition barrel (typically held by screws or clips).
- Turn the key to the accessory or on position as required to release the retaining catch, then remove the retaining screw or clip securing the barrel.
- Slide the old barrel out; transfer any necessary components (such as immobiliser ring or transponder housing) to the new unit if required by the vehicle’s configuration.
- Install the new barrel, secure with the original fixing, reassemble the column covers and reconnect the battery. Verify key operation and engine start.
Note: Some vehicles require immobiliser/key coding after replacing the barrel. If the vehicle uses a transponder key system, reprogramming by a qualified technician or dealer may be necessary to ensure the immobiliser recognises the key.
Common Faults And Expected Life
Failures that indicate replacement: increased key resistance, key sticking or jamming, inability to turn the key to start, or worn wafers/tumblers. Typical service life depends on usage and maintenance; frequent key use, dirt ingress and worn keys accelerate wear. Regular inspection and prompt replacement when symptoms appear prevent lockouts and ignition issues.
