Description
Lock set – driver and passenger door locks, fuel filler cap and ignition barrel plus 1x key. One door lock needs to be freed up. Applicable from year of manufacture 2002.
This complete lock kit is a practical replacement for Citroën Xsara vehicles and contains the two front door locks, the fuel filler cap lock and the ignition barrel, supplied with a single key. The kit is ideal for workshops and competent DIYers who need a keyed-alike solution that restores mechanical security and central locking function without the need for additional cutting or programming when the supplied key matches the set.
Technical Information

Function And Benefits
The set replaces the main mechanical locking points and ignition barrel: it secures the driver and passenger doors, protects the fuel filler, and restores ignition switch operation with one common key. Benefits include simplified key management, renewed mechanical reliability, and compatibility with standard door and ignition hardware used on the Xsara range.
Typical Causes Of Failure
Locks and ignition barrels typically wear out from long-term use and exposure: internal tumblers and levers suffer abrasion, plastic guide parts become brittle, springs weaken, and moisture or corrosion causes seizing. Common triggers on older Xsara cars are rusted or frozen mechanisms, worn or bent keys, water ingress into door cavities, and mechanical damage from forced entry or impact.
Installation Recommendations
For safe and reliable replacement follow these steps: disconnect the vehicle battery before working on the ignition barrel; remove the interior door cards to access the lock mechanism; disconnect electrical connectors and linkage rods carefully; unfasten mounting screws and withdraw the old lock assembly; transfer or replace any retained clips or rods and fit the new lock in reverse order, ensuring rods and linkages are correctly aligned and free-moving. Apply a light graphite or silicone-based lock lubricant after installation—avoid oil-based lubricants that attract dirt. If one door lock is stiff, free it before fitment by applying penetrating spray and gently operating the mechanism; do not force a stuck lock as internal parts can break. Check that the supplied key operates all locks smoothly before reassembling trim panels.
Practical Notes
Because one lock in this kit may require freeing up, inspect and, if necessary, clean or lubricate linkages and striker plates to ensure smooth operation. If the vehicle has aftermarket alarm or central locking modules, verify electrical connections after mechanical replacement. For workshop use, keep the original lock core if recoding or exact key reproduction is required.
