What The Kit Does
The kit replaces worn or damaged mechanical locking components. The Ignition Barrel restores reliable key turn and starting operation, the Driver′s Door Lock secures the main access point, and the Fuel Filler Cap Lock prevents unauthorized fuel access. The supplied Key Blade must be cut to the vehicle key profile and, if applicable, fitted with the correct transponder and immobiliser programming.
Installation
- Disconnect the battery before starting work and follow safety procedures.
- Remove steering column covers to access the ignition barrel retaining screw and release mechanism.
- Unscrew and extract the old ignition barrel; install the new barrel ensuring correct engagement with the steering lock and ignition switch.
- Remove and replace the driver′s door lock cylinder from the door lock mechanism (access may require inner door trim removal).
- Replace the fuel filler cap lock by removing the filler lid trim and securing the new lock in position.
- Have the key blade cut to the vehicle key pattern and program the transponder chip if the vehicle uses an immobiliser. Test all locking functions before reassembling trims.
Recommendation For Installation
- Use appropriate trim tools to avoid damaging interior panels.
- Cut the key blade by a professional locksmith or in-house key-cutting equipment to ensure correct profile.
- If the vehicle uses an immobiliser or remote locking, plan for transponder programming using dealer or aftermarket diagnostic tools.
- Lubricate cylinders with graphite or a dry lubricant; avoid oil-based sprays that attract dirt.
- Always verify mechanical operation of ignition and locks before final reassembly.
Why These Parts Fail Most Often
Common failure causes include normal wear of tumblers and wafers, corrosion from moisture ingress, contamination with dirt or debris, broken or worn key profiles, and forced entry attempts. Symptoms typically include difficulty turning the key, intermittent locking, key jamming or snapping in the cylinder, and inability to lock or unlock the fuel cap.
Suitability And Notes
Designed for Peugeot 307 models that use the listed product codes. The kit is suitable for mechanics and competent DIYers familiar with door trims, steering column disassembly and basic key services. For vehicles with electronic immobiliser systems, remember that the mechanical replacement may still require key transponder programming to enable engine start.
If you are a workshop professional the kit speeds up repairs and reduces vehicle downtime; if you repair your own car, follow the installation recommendations and, when in doubt, use professional key-cutting and programming services.
