Fitment
Intended for Peugeot 307 CC models manufactured up to 2004 (Coupe‑Cabriolet). Ensure the vehicle body type corresponds to the CC variant. The set targets vehicles with mechanical key locks; compatibility with different trim levels may vary depending on factory options.
Function And Common Failures
The lock set performs three primary functions: allow key operation for engine start (ignition barrel), secure the fuel filler flap, and lock/unlock the driver’s door. Common failure modes include:
- Wear Of Tumblers And Wafers: Repeated use leads to sloppy key turn, intermittent contact or inability to turn the key.
- Corrosion And Moisture Ingress: Especially in door and fuel flap locks, causing seizure or sticky operation.
- Broken Or Worn Key Blades: Metal fatigue or improper key cutting results in poor engagement.
- Mechanical Damage From Forced Entry Or Misuse: Bent components or broken retaining clips prevent normal function.
Installation Recommendations
Recommended For: Experienced Mechanics And Competent DIYers.
- Safety First: Disconnect the negative battery terminal before working on the ignition system to avoid short circuits and airbag/steering column risks.
- Ignition Barrel Removal: Remove the lower and upper steering column covers to access the barrel retaining screw or clips. Depress the release pin (usually accessed with the key in a specific position) and slide out the old barrel.
- Door And Fuel Filler Locks: Remove inner door trim or fuel flap access panel if required. Support rods and retaining clips should be handled carefully to avoid breakage—replace any brittle clips during reassembly.
- Key And Alignment: Use the supplied key blade to cut and check mechanical engagement. Lubricate locks with graphite or silicone‑based lubricant; avoid oil‑based products that attract dirt.
- Final Check: Reassemble column covers, reconnect the battery and verify smooth operation of ignition, central locking (if applicable) and fuel flap locking/unlocking.
- When To Seek Professional Help: If electrical immobiliser issues appear after installation, or if the vehicle has transponder keys and uncertain programming requirements, consult a qualified locksmith or workshop with diagnostic capability.
