Why Can't the Key Start the Car?

[VanTravis]

There are three reasons why the car key cannot start the vehicle: 1. The steering wheel is locked. 2. The gear is not in the correct position. 3. The car itself has a malfunction. Below are the specific details: 1. The steering wheel is locked. If the steering wheel cannot be turned and the key cannot be twisted, it is due to the vehicle's simple anti-theft function being at the intersection of key unlocking and lock cylinder torque. Simply turn the steering wheel lightly clockwise (or counterclockwise) and then gently twist the key to unlock it smoothly. 2. The gear is not in the correct position. For automatic transmission vehicles, the gear must be placed in "P" (some models include "N") to start. Some cars even prevent the key from being removed if the gear is not in "P." 3. The car itself has a malfunction. If the car still cannot start in "P" gear, or if the dashboard displays an abnormal gear position, it is recommended to seek repairs promptly, as it could be due to a faulty electronic gear sensor or an electro-pneumatic valve.
