Description
Lock Set: Ignition Barrel, Fuel Filler Cap, Driver’s Door Lock For PEUGEOT 307 Vehicles. 1x Blade Key
Complete lock set intended for Peugeot 307 owners and professional workshops: this kit includes the ignition barrel (steering lock cylinder), fuel filler cap lock and the driver’s door lock cylinder together with one blade key. Ideal for replacing worn or damaged cylinders after years of use or following cylinder damage from forced entry. Product codes 4162AS and 4162X4 are commonly used references when searching for the correct replacement part.
Features And Benefits
This combined set restores mechanical security and convenience in one intervention. Replacing the ignition barrel and door/fuel locks at the same time reduces repeated work and ensures a single key operation if cut to the same profile. The included blade key allows immediate mechanical operation; cutting to match original key code gives the best fit. Designed to match OE specifications for Peugeot 307 lock geometry and mounting points.
How The Part Works
The ignition barrel contains tumblers that align when the correct key is inserted, allowing the steering lock to disengage and the ignition switch to rotate. Door and fuel filler locks operate on the same principle: when the correct blade key aligns internal wafers, the cam rotates to open the lock. Wear, corrosion or mechanical damage prevents correct alignment, causing sticking, key jamming or complete failure to turn.
How To Replace
- Disconnect The Battery Before Starting Work To Avoid Electrical Faults Or Airbag Issues.
- Ignition Barrel: Remove Steering Column Trim Panels, Release Retaining Screw/Clip, Withdraw Old Barrel And Replace With New Unit Ensuring Correct Steering Lock Engagement.
- Driver Door Lock Cylinder: Remove Interior Door Card, Release Retaining Clip, Extract Old Cylinder And Fit New One, Adjust Linkage And Test Latch Operation.
- Fuel Filler Cap Lock: Access From Inner Wing Or Through Filler Opening Depending On Bodywork, Remove Fixings, Replace Cylinder And Test Lid Operation.
- After Mechanical Fitment, Ensure Smooth Operation Of All Locks And That Key Turns Freely Without Excessive Force.
Installation Recommendations
- Use Genuine Or High-Quality Replacement Cylinders To Maintain Security And Long Service Life.
- Cut The Blade Key To The Original Code Or Match All Cylinders To One Key If Required By An Experienced Locksmith.
- If The Vehicle Uses A Transponder Key, Be Aware That Key Immobilizer Programming May Be Required For Engine Start — Have Procedures Ready If Needed.
- Lubricate Lock Mechanisms With Graphite Or A Suitable Lock Lubricant; Avoid Oil-Based Products That Attract Dirt.
- Always Follow Manufacturer Procedures When Removing Trim And Components To Prevent Damage To Clips And Panels.
Why This Part Usually Fails

- Corrosion From Moisture Or Road Salts Causing Stiffness Or Seizure Of The Cylinder.
- Damaged Or Worn Keys That Deform And Accelerate Cylinder Wear.
- Forced Entry Attempts Or Vandalism That Physically Damage Lock Internals.
- Ingress Of Dirt, Dust Or Ice In The Fuel Filler Lock Leading To Jamming.
