What Causes a Car Key to Not Turn?

[VonArya]

The reason a car key won't turn is usually due to the steering wheel's automatic locking mechanism. The solution is to insert the key into the ignition while simultaneously turning the steering wheel left and right to unlock it. Important note: Avoid forcing the key to turn as this may cause bending or breaking. A car key consists of several components: upper cover, button assembly, upper shell, transmission shell, circuit board, lower shell, back cover, key, and key button. The working principle involves the battery emitting radio waves, which are received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, prompting the system's motor or electromagnetic coil to execute locking or unlocking actions.
