Description
Ignition Barrel For Peugeot 206 Vehicles — 1 Key
Product Overview
This replacement ignition barrel is designed for Peugeot 206 models and is commonly referenced by part number 4162Z1. Built as a direct-fit mechanical lock cylinder for the steering column, it accepts the standard Peugeot key and restores reliable key turn, ignition positions and steering lock operation. Ideal for professional workshops and experienced DIY mechanics searching by part number (4162Z1) or vehicle model.
Technical Information
- Manufacturer: Peugeot (Stellantis)
- Model: Peugeot 206, Peugeot 206+
- Product Codes: 4162Z1
- Other Numbers: NFP
Fitment And Replacement Procedure
Typical replacement steps for qualified personnel or experienced DIYers:
- Disconnect the vehicle battery before starting to avoid short circuits and protect electronic modules.
- Remove the steering column covers to access the ignition barrel (lower and upper shrouds usually held by screws/clips).
- Locate and release the retaining screw or clip that secures the ignition barrel in the steering column.
- With the key in the correct position, withdraw the old barrel from the column. Inspect the switch and surrounding harness for wear or corrosion.
- Install the new ignition barrel ensuring correct orientation and engagement with the ignition switch and steering lock mechanism.
- Reinstall column covers, reconnect the battery and verify all ignition positions, steering lock release, and accessory/power functions.
Note: If you reuse the original key, the transponder remains in the key head and the immobiliser recognition typically remains unchanged. If a new key or a different lock barrel that does not match the original transponder is used, key/immobiliser programming by a qualified technician may be necessary.
Installation Recommendations
- Always disconnect the battery before removal or installation to prevent damage to the vehicle electronics.
- Work on a stable steering wheel position and keep small fasteners organized to avoid reassembly issues.
- Inspect the ignition switch connector and wiring for heat damage, corrosion or loose contacts while the barrel is removed.
- Use the original key where possible to avoid immobiliser programming. If programming is required, have this carried out by a technician with the appropriate PSA diagnostic tools.
- Follow Renault/Peugeot manufacturer procedures for removal and installation to avoid damaging the steering column components.
Why This Part Most Commonly Fails
- Mechanical Wear: Frequent key use leads to worn tumblers and internal components, causing sticky operation or failure to turn.
- Key Damage: Bent or worn keys accelerate internal cylinder wear and can jam the lock.
- Contamination: Dirt, debris or corrosion inside the cylinder impedes smooth operation and can seize the barrel.
- Electrical Issues: On variants where the ignition barrel is integrated with switch contacts, worn or damaged contacts can cause intermittent power/ignition problems.
Benefits For The Workshop
Fast direct-fit replacement by part number 4162Z1 reduces diagnostic time and gets vehicles back on the road quickly. The unit restores mechanical security and reliable ignition function with minimal adaptation when the original key is reused.
