What Causes the One-Button Start to Fail Ignition?

[Annabeth]

The one-button start failing to ignite can be caused by the following reasons: 1. Steering wheel lock: The steering wheel lock is a simple anti-theft feature. When the car is turned off, turning the steering wheel from the centered position to a certain angle in one direction will cause a "click" sound, indicating the steering wheel is locked. In this state, the one-button start function will not work. 2. Gear not in P position: For automatic transmission vehicles (AT, CVT, AMT), manufacturers specify in the manual that the gear must be in the P position when starting the engine. Starting the engine in D or R gear poses a significant safety hazard due to potential sudden vehicle movement. 3. Smart key battery dead: When the smart key's battery is dead, the key's transmission power is very low, making it difficult for the car's sensors to detect it, thus preventing the one-button start from completing the ignition.
