Description
Complete ignition switch and lock set for Citroën C3 Picasso, supplied as an original PSA Citroën Peugeot assembly with part code 4162SV. This kit includes the ignition switch (ignition barrel), driver door lock, fuel filler cap lock and two keys. The set is intended for direct replacement of worn or damaged locking components to restore vehicle security and reliable operation.
What The Kit Contains
This package contains:
- Ignition switch / ignition barrel
- Driver door lock
- Fuel filler cap lock
- Two matching keys
Condition And Origin
Original PSA Citroën Peugeot components, removed from a donor vehicle and inspected for correct mechanical operation. Parts are sold as used; each item has been checked visually and functionally to ensure it engages and turns as intended. Replacement of locks is a practical option when keys are lost, locks are worn, or components are mechanically damaged.
Function And Common Failures
The ignition switch provides electrical connection for starting and powering vehicle circuits and also integrates the mechanical barrel for key operation. Door and fuel cap locks provide physical security. Typical causes of failure include key wear, internal tumblers wearing out, contamination from dirt or moisture, corrosion, or mechanical impact. There is no fixed lifespan; replace locks when operation becomes stiff, keys do not turn smoothly, or security is compromised.
Compatibility And Fitment
Designed specifically for Citroën C3 Picasso models that accept PSA original parts with code 4162SV. Always verify fitment by comparing part codes and lock shapes before installation. If unsure, consult vehicle VIN or a parts catalog to confirm compatibility.
Installation & Practical Notes
Basic installation steps (overview):
- Disconnect the vehicle battery before starting work to prevent electrical shorting.
- Remove interior trim or steering column covers as required to access the ignition switch; remove door trim panels to replace the door lock.
- Unscrew and remove the old ignition switch or lock barrel, transfer any required retaining clips or housings, and fit the replacement in the correct orientation.
- Reassemble trims, reconnect the battery, and check mechanical operation of keys in ignition, door and fuel cap.
Note: This kit includes two keys. Depending on the vehicle’s immobiliser system, the keys may require programming to enable engine start. Programming can usually be done by a dealer or a locksmith with PSA-capable diagnostic equipment. If you are a DIY mechanic, check whether your vehicle accepts mechanically-cut keys only or also requires electronic transponder programming.
Benefits For Mechanics And DIYers
Buying a complete set reduces installation time and ensures matching keys across ignition and locks. The set is practical for workshops performing body repairs, lock replacements after theft or vandalism, or for owners restoring the vehicle’s security functions. As original PSA components, fitment and mechanical compatibility are optimised for the Citroën C3 Picasso platform.
