What Causes the Car Ignition Lock Cylinder to Not Turn?

[ColemanLee]

Car ignition lock cylinder may not turn due to sticky lock pins, a stuck key and wafer, or a locked steering wheel. Here is relevant information: 1. LOCK: The lock position, which must be engaged when parking and turning off the engine. Only in this position can the key be removed. If the steering wheel is turned at this time, the steering wheel will also lock. The next time you start the car, you need to turn the steering wheel while twisting the key; otherwise, the key won't turn. 2. ACC: Accessory position. When engaged, only a few components receive power, such as the radio and cigarette lighter. 3. ON: Full power position. When engaged, all vehicle components receive power. This is the position used during normal driving. 4. START: Start position. This position is only used when starting the engine. After the engine starts, releasing the key will automatically return it to the ON position.
