Key Features
- Includes ignition switch, driver’s door lock and one mechanical key for immediate use.
- Direct replacement for Peugeot 407; compatible with some Citroën and Peugeot (PSA) models – always verify fitment by part number before purchase.

Installation & Fitment
Typical replacement steps: disconnect the vehicle battery, remove steering column covers, unfasten the old switch/lock unit, install the replacement and reconnect the electrical connector. After installation, test ignition functions, accessory positions and door locking. If the vehicle uses an immobilizer transponder, the new key may require pairing or programming with the appropriate diagnostic tool or dealership service.
Common Faults & Lifespan
Failures commonly result from mechanical wear (worn tumblers), degraded electrical contacts inside the ignition switch, corrosion or moisture ingress and physical damage. Symptoms include the key not turning, intermittent starter engagement, loss of accessory power, or a sticking door lock. Lifespan depends on usage and environment; replace at first signs of persistent malfunction to avoid immobilization or security issues.
