Function And Common Faults
The Door Lock Provides Mechanical Latching And, Where Fitted, Electrically Operated Locking Via Actuator. The Fuel Filler Flap Lock Secures The Fuel Cap Area Against Unauthorized Access. The Ignition Barrel Houses The Key Cylinder And Mechanical Tumblers That Allow Key Turn To Start The Vehicle And Engage The Steering Lock Mechanism.
Common Failures Include:
- Worn Tumblers In The Ignition Barrel Causing Key To Stick Or Fail To Turn.
- Corrosion Or Dirt Buildup Preventing Smooth Lock Operation, Especially In Areas Exposed To Road Salt Or Moisture.
- Broken Or Weak Door Lock Actuator (If Electrically Assisted) Resulting In Intermittent Locking Or Failure To Lock/Unlock.
- Physical Damage Or Vandalism To The Fuel Filler Flap Lock.
