Function
The ignition barrel (lock cylinder) provides the mechanical interface for the vehicle key: it Operates The Ignition Switch, Unlocks The Steering Column, And Allows The Starter Circuit To Engage. On Many Xsara Picasso Models The Key Contains A Transponder That Works With The Vehicle Immobilizer—Mechanical Operation Is Possible With The Supplied Key, But Electronic Authorization May Be Required For Engine Start.
Installation And Recommendations
- Disconnect The Battery Before Starting Work To Prevent Short Circuits And Protect Electronic Modules.
- Remove Steering Column Covers To Access The Ignition Barrel Retaining Screw(s).
- With The Key In The Correct Position, Remove The Retaining Screw And Slide Out The Old Barrel.
- Fit The New Barrel Ensuring Proper Alignment Of The Steering Lock Mechanism; Secure With The Retaining Screw To Manufacturer Torque.
- Verify Mechanical Operation: Lock/Unlock, Ignition Positions, And Steering Lock Engagement.
- If The Vehicle Uses A Transponder Key, Have The Supplied Key Cut And Programmed By A Qualified Locksmith Or Dealer So The Immobilizer Recognizes The Key.
- Always Follow Manufacturer Procedures When Reassembling Steering Column Covers And Reconnecting The Battery.
Why This Part Fails Most Often
- Mechanical Wear: Frequent Key Use Causes Tumblers And Springs To Wear Over Time.
- Key Damage Or Excessive Force Can Deform The Key Or Internal Components, Preventing Proper Operation.
- Contamination: Dirt, Debris Or Corrosion Inside The Barrel Leads To Sticking Or Jamming.
- Attempted Theft Or Forced Entry Which Damages The Cylinder Or Steering Lock.
Practical Tips
- Inspect The Key For Wear Before Replacing The Barrel; Sometimes Replacing The Key Alone Prevents Early Recurrence.
- When Programming A New Transponder Key, Use Proper Diagnostic Equipment Or A Specialist To Avoid Immobilizer Lockout.
- Keep The Replacement Cylinder Clean And Protect It From Moisture To Maximize Service Life.
