Lock Set For Peugeot 308 T7
Driver Door, Ignition Lock Barrel, Fuel Tank Lock
2 x Key
Product Overview
This lock set is designed for Peugeot 308 (T7) vehicles and includes the driver door lock, the ignition lock barrel and the fuel tank lock, supplied with two keys. Ideal for mechanics and experienced DIY enthusiasts looking for a direct replacement that restores mechanical locking functions and basic vehicle security. The part is associated with Stellantis / Peugeot applications and commonly searched by OEM part numbers, which improves findability in online stores and search engines.
Why Choose This Lock Set
Replacing a worn or damaged lock assembly can eliminate key jamming, prevent door or fuel flap failures and restore smooth ignition operation. This set saves time by providing all commonly replaced locks for the driver side in one package and includes two keys for immediate use or cutting/programming as required by the vehicle.
How The Part Works And Common Faults
The door lock secures the driver door and interacts with the central locking mechanism. The ignition lock barrel houses the mechanical tumblers and interfaces with the vehicle’s ignition switch to allow engine start when the correct key is inserted. The fuel tank lock protects the filler cap. Typical failure modes are mechanical wear of tumblers, internal springs breaking, key damage, contamination or corrosion from moisture and debris. Over time, repeated use and environmental exposure cause increased play in the cylinder and difficulty turning the key.
Installation Recommendations
Before starting any work, always disconnect the battery to reduce the risk of short circuits and follow the vehicle manufacturer’s removal and installation procedures. Basic steps:
- Door Lock: Remove the door card and water shield, disconnect linkages and electrical connectors if present, remove retaining screws or rivets and extract the lock cylinder. Install the new lock, reconnect linkages and test operation before reassembling the trim.
- Ignition Lock Barrel: Remove steering column covers, note the position of the cylinder and any retaining clips or bolts, extract the old barrel with the key in the required position and fit the replacement. Verify mechanical engagement and steering lock operation before reconnecting the battery.
- Fuel Tank Lock: Access from inside the wheel arch or through the fuel filler area, remove retaining screws or clips and replace the lock. Ensure the locking mechanism moves freely and the fuel cap seals correctly.
Keys supplied may require cutting and/or transponder programming depending on the vehicle year and immobilizer system. Key cutting and immobilizer pairing should be performed by a qualified technician with appropriate PSA diagnostic tools when necessary (DiagBox/Lexia/PP2000).
Reason For Failure
Most failures are caused by long-term mechanical wear, corrosion (especially in regions with road salt or high humidity), debris ingress into the cylinder, broken springs or worn tumblers. Keys bent or broken in the lock also commonly cause damage to the cylinder. Lack of lubrication and forced turning of a stuck key accelerate wear and can lead to complete seizure of the lock.

Notes
Use appropriate lock lubricant (graphite or specialist lock spray) during installation to improve longevity. If the vehicle uses transponder keys, ensure the key transponder is correctly programmed for the vehicle’s immobilizer system; otherwise the engine may not start even if the mechanical lock operates.
