What Are the Reasons Why a Car Key Cannot Start the Vehicle?

[DiBeau]

There are three reasons why a car key cannot start the vehicle: 1. The car steering wheel is locked. 2. The gear is not in the correct position. 3. The car itself has a malfunction. Detailed explanations are as follows: 1. The car steering wheel is locked. The steering wheel cannot be turned, and the key cannot be twisted either. This is a simple anti-theft feature of the vehicle, which happens to be at the intersection of key unlocking and lock cylinder torque. Just gently turn the steering wheel clockwise (or counterclockwise) and lightly twist the key to unlock it smoothly. Reminder: When parking, try to straighten the steering wheel before turning off the engine and removing the key. 2. The gear is not in the correct position. For automatic transmission cars, the gear must be placed in "P" (some cars include "N" gear) to start. Some cars cannot even remove the key unless the gear is in "P". Reminder: Develop good habits by placing the gear in "P" before turning off the engine. Check the gear position before starting. 3. The car itself has a malfunction. If the car still cannot start in "P" gear, or if the dashboard shows an abnormal gear position, it is recommended to seek repair promptly, as it could be due to a damaged electronic gear sensor or electro-pneumatic valve.
