How To Replace (Overview For Mechanics / Skilled DIY)

Replacing The Components Requires Basic Trim Removal And Standard Mechanical Tools. Steps Commonly Include:

1. Disconnect The Battery Before Starting Work To Avoid Electrical Damage And For Safety.
2. Ignition Barrel: Remove Steering Column Trims, Release The Fixing Screw/Clip, Withdraw The Old Barrel (Follow Manufacturer Clips/Retainers) And Fit The New Barrel. If Reusing The Original Key, The New Barrel Should Operate Mechanically; If Fitting New Keys, Transponder Programming May Be Required (See Notes).
3. Driver Door Lock: Remove Inner Door Card, Disconnect Linkages And Electrical Connectors (If Applicable), Unscrew The Lock Mechanism And Replace With The New Unit. Check Central Locking Actuator Operation After Assembly.
4. Fuel Flap Cap: Remove Access Panels If Required, Replace Locking Cylinder Or Flap Cap And Verify Smooth Operation.
5. After Installation: Reassemble Trims, Reconnect Battery, Test All Locks, Check That Door Latches And Central Locking Work Correctly, And Verify That The Ignition Turns Smoothly And The Engine Starts With The Key.

Mounting Recommendations

• Always Disconnect The Battery Before Starting Work On The Ignition Or Locks.
• Use Appropriate Trim Tools To Avoid Damage To Interior Panels.
• Lubricate New Cylinders With Suitable Lock Lubricant Or Dry Graphite; Avoid Using Motor Oil Or Grease That Attracts Dirt.
• If The Kit Is Supplied With Blank Keys, Have Keys Cut To The Existing Code Or Use The Original Key If Replacing Only The Cylinders.
• If Installing New Keys With Transponders, Programming May Be Required Using PSA-Compatible Diagnostic Equipment Or An Authorized Locksmith. When In Doubt, Entrust Programming To A Professional With Experience On Peugeot/ Citroën Systems.

Final Notes For Professionals

• Check Mechanical Fitment And Function After Installation; Minor Adjustments To Linkages Or Latches May Be Necessary.
• When New Electronic Keys Or Immobilizer Work Is Involved, Use PSA Diagnostic Tools Or A Qualified Workshop For Key Programming To Ensure Reliable Start-Up.

Reason Most Frequently Caused Failure

Most Failures Are Caused By Mechanical Wear Of The Cylinder/Tumblers And By Corrosion Or Dirt Ingress. Keys Worn By Long-Term Use Or Broken Keys Inside The Cylinder Are Also Very Common Causes.
