This complete lock set is the convenient solution for Citroën C1 and Peugeot 107 owners and technicians who need to replace the main mechanical locking components. The set includes door locks for both the driver and passenger sides, the fuel filler cap lock and the ignition barrel together with two key wafers. It is designed as a direct replacement for vehicles equipped with central locking (no separate rear boot lock included).

Technical Information

Manufacturer: Stellantis (Citroën / Peugeot)
Model: Citroën C1, Peugeot 107
Product Codes: 1608745780, 1608745880
Additional Numbers: 4162FH, 4162FK

Function And Benefits

The set restores mechanical locking and ignition functions: door latching and unlocking, secure closure of the fuel filler cap and reliable ignition switching. Replacing worn or damaged locks improves vehicle security, prevents key jamming and ensures correct operation of the central locking system.

Typical Failure Modes And Why They Occur

Locks and ignition barrels commonly fail due to wear of internal tumblers and wafers from prolonged use, dirt and corrosion (moisture ingress), broken springs or damaged actuator linkages in the door mechanism. Keys that are bent or worn accelerate wear of the lock internals. Symptoms include difficulty turning the key, intermittent central locking operation, jamming, or inability to lock/unlock specific doors.

Installation Recommendations

Recommended For: Professional Auto Technicians And Experienced DIY Enthusiasts.
– Before Starting Work, Isolate The Electrical System Where Necessary And Take Appropriate Safety Precautions (Disconnecting The Battery Is Recommended When Working Near The Ignition Switch Or Electrical Connectors).
– Remove Interior Door Trim To Access Lock Mechanism; Detach Linkages And Electrical Connectors Carefully.
– Remove The Old Lock Barrel And Replace With The New One; Fit The Supplied Key Wafers Or Have Keys Cut To Match The New Cylinder If Required.
– For The Ignition Barrel, Ensure The Steering Wheel Is Unlocked And Follow Manufacturer Procedures To Avoid Damaging Steering Column Components.
– Reassemble Door Panel, Reconnect Linkages And Test All Functions: Manual Key Operation, Central Locking Actuator Function, Fuel Cap Lock Operation And Ignition Switching.
– Use Suitable Lock Grease Or Dry Graphite In The Cylinder To Improve Longevity; Avoid Excessive Oil That Attracts Dirt.

Compatibility And Notes

Fits Citroën C1 And Peugeot 107 Vehicles That Use The Listed Part Numbers. The Kit Does Not Include A Separate Rear Boot Lock Because The Described Vehicle Was Equipped With Central Locking. Two Key Wafers Are Supplied; Keys May Need To Be Cut Or Matched To The Vehicle. Check Part Numbers 1608745780 / 1608745880 / 4162FH / 4162FK When Searching For Compatibility.

Why Replace Rather Than Repair

In many cases, internal wear, corrosion or broken components inside locks are easiest and fastest to correct by replacement rather than individual part repair. A full kit restores consistent operation across all doors and the ignition, reducing repeated workshop visits.

Technical Information

Features: The set replaces mechanical locks used for the driver door, fuel filler cap and the ignition barrel. Keys are supplied without remote electronics but include blank transponder chips that must be cut and programmed to the vehicle’s immobiliser system. The tailgate lock is compatible with central locking systems.

Compatibility And Fitment

Compatible with first-generation Citroën C1 and Peugeot 107 models. This part is often searched and ordered by its product number 1608745880 — useful when sourcing a precise replacement.

Typical Faults And Why They Fail

Common symptoms leading to replacement include difficulty turning the key, intermittent central locking operation, water ingress or corrosion in the lock barrel, worn key profiles, broken tumblers or failure of the central locking actuator. Electrical faults in the vehicle’s locking circuit can also mimic mechanical lock failure.

Replacement And Installation Notes

Basic replacement steps (typical for door lock and ignition barrel): disconnect the battery; remove interior door trim to access the lock assembly; unclip/disconnect any electrical connectors; remove mounting screws/bolts and replace the lock body or cylinder; refit trim and reconnect the battery. For the ignition barrel, follow vehicle-specific procedures and immobiliser precautions.

Key cutting and immobiliser programming: blanks must be cut to match the original key profile. Transponder chips in the supplied keys are blank and require programming or cloning to the vehicle’s immobiliser using dealer diagnostic equipment or an experienced locksmith tool. If the vehicle requires ECU or immobiliser registration, professional programming is recommended.

Maintenance And Recommendations

To extend lock life, keep locks lubricated with a graphite-based or manufacturer-recommended lubricant, avoid forcing worn keys, and protect door seals to reduce water ingress. When replacing, verify central locking actuator operation and check wiring connectors for corrosion.

Note: Remote controllers (key fobs) are sold separately and can be sourced to match this lock set. If you are unsure about programming or fitment, consult a qualified technician.
