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.
