High-quality lock set tailored for the Citroën C4 Picasso (first series). This complete kit includes the driver’s door lock mechanism, ignition barrel and three keys — ideal for mechanics and experienced DIYers who need a reliable replacement during bodywork, accident repairs or routine maintenance. The set is commonly searched by product codes 4162KF / 4162KC (and related reference 4162XT), so it is perfect for customers who look up parts by reference number.

The locks restore mechanical security and steering ignition function; replacing the worn or damaged lock assembly eliminates door jamming, key rotation problems and improves vehicle security. Supplied components are ready for mechanical installation, but keys may require cutting and, depending on vehicle immobilizer configuration, further programming to enable engine start.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Citroën C4 Picasso (First Generation)
• Product Codes: 4162KF, 4162KC
• Additional Numbers: 4162XT

Installation Recommendations

• Before starting work, disconnect the vehicle battery to prevent short circuits and to protect any immobilizer or electronic modules.
• Remove the interior door card and any trim to access the door lock mechanism. Support the door glass if required.
• Unscrew the lock assembly mounting bolts, detach mechanical linkages and any electrical connectors for central locking (if present).
• Replace the ignition barrel by removing the retaining clip or screws; ensure the new barrel engages correctly with the steering column lock when installing.
• Install the new door lock, reconnect linkages and connectors, then test mechanical operation of the latch and locking function before refitting the door card.
• Have the keys cut to match the supplied blanks. If the vehicle uses transponder immobilizer keys, programming or synchronization may be required for the engine to start — this is done with appropriate diagnostic equipment or by a qualified locksmith.
• Lubricate the lock cylinder with a dry graphite or specialist lock lubricant; avoid wet oils that attract dirt.

Why This Part Most Commonly Fails

• Mechanical Wear: Years of use cause tumblers and wafers inside the cylinder to wear, leading to difficult or incomplete key rotation.
• Corrosion and Contamination: Water ingress, dirt and salt accelerate corrosion of lock internals and linkages, causing sticking or seizure.
• Key Damage: Worn or bent keys damage the cylinder profile and increase wear on tumblers.
• Forced Entry or Impact: Attempts to force the lock or accident damage to the door can deform components and impair operation.
• Actuator Failure: In locks with integrated central locking actuators, the small electric motor or gears can fail and prevent locking/unlocking even if the mechanical cylinder works.

Notes for Mechanics and DIYers

This set is aimed at professionals and experienced DIY enthusiasts who are comfortable with door disassembly and key handling. Use common workshop tools and follow manufacturer torque and reassembly guidelines. Searching by the listed product codes (4162KF / 4162KC / 4162XT) will help you quickly match the correct part for the Citroën C4 Picasso first generation.

Technical Information

Manufacturer: Stellantis (Citroën / Peugeot)
Model: Citroën C3 Picasso, Citroën C4 Picasso, Citroën C5 X7, Peugeot 207, Peugeot 308
Product Codes: 9671153480, 8719G5
Additional Numbers: 8719G5, 9671153480

Function And Application

The lock assembly secures and releases the rear door or tailgate as part of the vehicle’s central locking system. The unit contains mechanical latches and an electrical actuator that receives locking/unlocking commands from the remote key, central locking module or interior switches. When functioning correctly it ensures reliable closure, prevents unwanted opening during driving and integrates with convenience functions such as remote unlocking and alarm sensors.

Typical Failure Modes

• Water Ingress And Corrosion: Moisture penetration can corrode electrical contacts and metal linkages, causing intermittent operation or complete failure.
• Worn Plastic Gears Or Mechanical Linkage: Repeated use and age can wear internal plastic components or break linkage arms, preventing the latch from engaging.
• Actuator Motor Failure: The small electric motor or solenoid inside the unit can seize or lose power due to wear or electrical faults.
• Connector Or Wiring Issues: Corroded pins, damaged wires or poor grounding may interrupt signals to the lock.
• Impact Damage: Rear-end collisions or forceful closing can bend or damage the latch mechanism.

Replacement And Installation

Basic replacement steps (for experienced technicians or informed DIYers):

• Disconnect The Battery Before Starting Work To Prevent Short Circuits.
• Remove Interior Trim Of The Rear Door/Tailgate To Access The Lock Assembly.
• Disconnect The Electrical Connector And Any Linkage Rods Or Cables; Note Their Positions For Reassembly.
• Unscrew The Fixing Bolts And Extract The Old Lock Unit.
• Transfer Any Required Mechanical Parts (If Applicable) From The Old Unit To The New One.
• Fit The New Lock, Reconnect Linkages And Electrical Connector, Refit Trim And Reconnect The Battery.
• Check Function: Test Locking/Unlocking With Remote And Interior Switches; Verify Mechanical Latch Engagement.

Installation Recommendations

• Use Correct Tools And Take Care With Plastic Trim Clips To Avoid Breakage.
• If Connector Pins Show Corrosion, Clean Or Replace Them Before Reassembly.
• Apply Dielectric Grease To Electrical Connectors To Reduce Future Corrosion.
• Ensure Linkage Rods Are Properly Adjusted And Secure To Avoid Misalignment Of The Latch.
• After Installation, Cycle The Lock Several Times And Check That The Tailgate Closes And Latches Securely.

Why The Part Most Often Fails

Environmental exposure (water, road salt) and mechanical wear are the primary causes of failure. The combination of water ingress and aging plastic/metal components leads to corrosion, seized actuators or broken internal gears. Frequent use, impacts and poor sealing around the tailgate area accelerate deterioration.
