Description
Product Overview
This ignition switch assembly with one key is a direct replacement for Citroën C5 vehicles produced between 2001 and 2007. Supplied under the identifying code 4162CE, this unit is frequently searched by part number by both professional mechanics and DIY enthusiasts looking for a reliable electrical and mechanical ignition solution.
What It Does
The ignition switch controls the vehicle’s electrical circuits for accessory, ignition and starter functions and contains the mechanical lock cylinder that secures the steering column. A faulty switch can prevent the engine from starting, cause intermittent power loss to accessories, or result in a key that is difficult to turn or gets stuck.
Included
- Ignition switch assembly (electrical switch and mechanical barrel)
- One key
Installation Notes
Basic replacement steps: disconnect the negative battery terminal; remove the lower and upper steering column covers; undo the retaining screws or clips that secure the switch/cylinder; disconnect the wiring harness and remove the old unit; fit the new assembly and reconnect in reverse order. After fitting, verify all positions (accessory, ignition, start) and test starter operation. If the supplied key contains a transponder chip, immobilizer reprogramming or key coding with a diagnostic tool or dealer equipment may be necessary for the vehicle to recognize the new key.
Common Faults & Maintenance
Typical causes of failure include mechanical wear of the tumbler, contamination from dirt or moisture, corrosion of electrical contacts, and broken or worn keys. Symptoms include intermittent electrical faults, inability to start, a key that wobbles or does not turn smoothly, or the accessory circuit not engaging. Regular inspection and replacement at the first sign of malfunction will avoid unexpected breakdowns. Avoid excessive lubricant inside the barrel; keep keys free of debris and do not use heavy-weight keychains that add stress to the lock mechanism.
Fitment & Compatibility
Intended for Citroën C5 models from 2001 to 2007 (first generation). Always verify fitment by comparing the part number (4162CE) with the existing unit on the vehicle or by checking vehicle compatibility using VIN/registration data. This part is aimed at professional workshops and competent DIYers who are able to perform steering column access and basic electrical checks.
