Product Overview
This complete lock and key set is designed for Citroën Berlingo II and Peugeot Partner II models and provides a cost-effective solution when multiple locks or keys are worn, broken or missing. The kit contains the ignition barrel (switch cylinder), two door locks and the fuel filler cap lock. Ideal for mechanics and DIY enthusiasts who need to restore vehicle security and central locking function quickly.
Key Benefits
- Direct replacement for worn or damaged locks on Berlingo II/Partner II models.
- Includes ignition barrel and multiple door locks to allow full-door set renewal without sourcing separate parts.
- Simplifies key management by replacing damaged tumblers and worn barrels at once.
- Suitable for both workshop fitment and competent DIY installation.
How It Works And Typical Faults
Door and fuel-cap locks are mechanical assemblies that rely on tumblers, springs and lubricated surfaces. Over time they fail due to wear, corrosion, contamination (dirt, salt, moisture) or key damage. The ignition barrel can develop internal wear or binding, causing poor key turn action or failure to start. The rear tailgate lock is often exposed to moisture and road dirt, which can cause it to seize or rust — as noted in this unit.
Replacement And Installation
Replacement is straightforward for an experienced technician and possible for a competent DIYer with basic tools.
- Ignition Barrel: Remove steering column covers, extract retaining screws or clips, withdraw old barrel and fit new one. Ensure key turns freely before reassembly.
- Door Locks: Remove door card/panel, disconnect linkage and electrical connector (if central locking), remove retaining bolts and fit replacement lock. Check latch operation and adjust striker if necessary.
- Fuel Filler Cap Lock: Access through wheelarch or filler opening depending on body design, remove retaining screws and replace lock.
- Rear Tailgate Lock: If seized, try penetrating lubricant and gentle mechanical freeing; replacement may be required if heavily corroded.
Safety Tip: Disconnect the battery before working on the ignition switch or any electrical connectors to avoid short circuits and accidental airbag deployment. Use manufacturer-recommended procedures for reassembly.

Installation Recommendations
- Inspect all linkages and cables while doors are open; replace any worn rods or clips to ensure reliable operation.
- Before final assembly, lubricate moving parts with appropriate lock grease or graphite powder for smooth action; avoid heavy oils that attract dirt.
- Check key condition—worn keys can damage new tumblers. If keys are badly worn, consider cutting new keys from lock code or replacing the key set.
- After installation, verify central locking and manual lock operation on all doors, and ensure the immobiliser/key transponder functions (if applicable).
Why This Part Fails Most Often
Failures are typically caused by a combination of wear and environmental factors: corrosion from moisture and road salt, dirt ingress that jams tumblers, wear of internal springs and tumblers from prolonged use, and damaged or bent keys. The rear tailgate lock in particular is vulnerable to water, mud and mechanical damage, which can lead to seizing as noted.
Who Should Fit This
Recommended for professional technicians and experienced DIYers. If electrical immobiliser or key transponder issues arise after replacing the ignition barrel, specialist diagnostic tools may be needed to align immobiliser data or program keys.
