Function And Fitment
The kit replaces the vehicle’s locking components responsible for secure door operation, fuel filler locking and key-operated ignition. The ignition barrel houses the mechanical tumblers (and typically a transponder reader when fitted to the vehicle), while the door and fuel flap locks secure access points and are often integrated with the central locking mechanisms. Intended specifically for the facelift variant of the Peugeot 307 — confirm compatibility by matching the product codes listed above when searching.
Installation
Replacement can be performed by experienced DIYers or professional technicians. Typical steps:
- Remove the relevant interior trims (door card, inner trunk or wheel-arch liners) to access the locks.
- Disconnect electrical connectors and linkage rods/cables from the old lock assemblies.
- Unbolt and extract the old locks and ignition barrel. Note the orientation and routing of linkages.
- Install new locks in reverse order, reconnect linkages and connectors, then test mechanical operation and central locking functions before reassembling trims.
- Cut Keys And Program: The set includes two keys. Keys may require cutting and, when fitted with transponders, immobilizer programming to match the vehicle’s security system.
Installation Recommendations
- Work In A Clean, Dry Environment To Avoid Contaminants Entering Lock Mechanisms.
- Use Appropriate Tools To Avoid Damaging Trim Clips And Fasteners.
- If The Ignition Barrel Or Keys Use A Transponder, Ensure Proper Immobilizer Programming Is Performed Using Suitable Diagnostic Equipment.
- After Installation, Verify That Door Latches, Central Locking And Ignition Respond Correctly Before Completing The Job.
Why This Part Fails Most Often
Lock components wear out primarily due to mechanical wear, water ingress and corrosion, or broken internal components (springs, tumblers, latch pawls). Common causes of failure include:
- Frequent Use And Key Wear Leading To Slippage Or Difficulty Turning In The Ignition Barrel.
- Corrosion Or Dirt In Door And Fuel Flap Locks Causing Stiff Operation Or Complete Seizure.
- Damage To Linkage Rods Or Plastic Clips From Impact Or Age, Preventing Proper Locking.
- Failure Of Central Locking Actuators That Can Affect Lock Performance.
Notes For Mechanics And DIYers
Search By Product Codes (4162KF / 4162KG / 4162XT) To Quickly Locate Matching Parts. Ideal For Workshops Performing Multi-Point Lock Replacements Or For Owners Replacing Single Worn Components. When Keys Are Replaced, Expect Key Cutting And Possible Immobilizer Programming Steps—plan accordingly.
