Technical Information

• Manufacturer: Stellantis (Citroën)
• Model: Citroën Xsara Picasso
• Product Codes: 4162HK, 4162CJ, 4162.CJ, 4162.HK, 4162FF
• Additional Numbers: (N68), NFP

Compatibility and Notes

Intended for Citroën Xsara Picasso models that use the lock designs referenced by the product codes above. This set contains left and right front door locks, the fuel filler cap lock and the ignition barrel supplied with a single matching key. Verify visually that lock shapes and mounting points match your vehicle before installation.

Installation Recommendations

• Disconnect the negative battery terminal before starting work, especially when replacing the ignition barrel, to avoid electrical faults and to follow safe workshop practice.
• Use plastic trim tools to remove door cards to prevent damage to clips and trim.
• Lubricate lock mechanisms with graphite or a dry lock lubricant. Avoid petroleum-based oils that attract dirt and cause sticking.
• If the ignition key contains a transponder chip, transfer the transponder to the new key or have the key programmed by a qualified locksmith or dealer. Mechanical keys without transponders are plug-and-play.
• After installation, check mechanical operation of all locks and verify central locking and ignition function before road use.

Replacement Procedure (Overview)

1. Prepare tools: trim tools, Torx/Phillips drivers, socket set and pliers.
2. Disconnect the negative battery terminal.
3. Remove the interior door trim to access the lock assembly and actuator.
4. Disconnect electrical connectors for central locking/actuator where applicable and detach linkage rods.
5. Unscrew and remove the old lock unit. Fit the new lock in the correct orientation and secure fasteners.
6. Install the ignition barrel by removing the steering column covers, extracting the old barrel and inserting the new unit; reassemble covers.
7. Reconnect linkages and electrical connectors, refit door cards and reconnect the battery.
8. Test all functions: manual door operation, central locking, fuel flap lock and ignition start.

Why This Part Most Often Fails

• Mechanical Wear: Tumblers, levers and latch components wear over time from repeated use, leading to jamming or loose operation.
• Corrosion and Moisture Ingress: Water or salt exposure causes corrosion, especially on door and fuel cap locks, resulting in stiffness or seizure.
• Damaged Key: Bent or worn key blades damage tumblers and can break inside the lock.
• Central Locking Actuator Issues: Electrical actuator failures may be interpreted as lock failure when the mechanical lock is intact.
• Contamination: Dirt and debris accumulate in the lock mechanism, increasing wear and causing sticking.

Practical Tips

• When replacing multiple locks, use the supplied one-key set to avoid carrying several keys for the same vehicle.
• Always inspect linkages and actuator condition while the door card is removed; replacing worn rods or clips prevents premature rework.
• Keep a spare key blade and transfer any transponder if required to reduce downtime.

Replacement And Installation Notes

General guidance for replacing the ignition switch and door lock cylinders:

• Disconnect the vehicle battery before beginning any work on the ignition to avoid electrical hazards and immobilizer complications.
• Ignition switch: remove steering column trim panels, locate the lock barrel retaining clip or screw, remove the old cylinder and install the replacement. Reassemble trims and test key rotation and starter engagement.
• Door lock cylinders: remove the inner door trim to access the lock mechanism, disconnect linkages, unfasten retaining bolts or clips, withdraw the old cylinder and fit the new one. Reattach linkages and test locking and unlocking functions.
• Fuel flap lock: access via exterior or interior service point depending on model; replace cylinder and confirm flap latches correctly.
• After mechanical installation, use your original remote and immobilizer/transponder chip to ensure the engine will start and central locking/remotes function as before.

Common Causes Of Failure

Lock cylinders and ignition barrels wear out due to metal fatigue, key wear, corrosion from moisture ingress, and accumulated dirt. Symptoms include stiff key operation, intermittent contact in the ignition, key jamming, or door locks that do not turn smoothly. Regular lubrication and inspection can extend service life, but replacement is the long-term solution when mechanical wear is present.

Why Choose This Set

This kit provides the mechanical components needed to restore locking function across the driver and passenger doors, fuel flap and ignition barrel. It is a practical choice when keys are duplicated or when lock cylinders show wear. Note that electronic immobilizer components are not supplied and must be reused from your vehicle to maintain security and engine start capability.

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.
