What is the reason why the car with one-button start cannot detect the remote key?

[JourneyLynn]

The reasons why the car with one-button start cannot detect the remote key are: 1. Check if the key is nearby. The one-button start of the car relies on the key for sensing. If the key is not present, the car cannot start; 2. Check if there is an operational error. If you only press the button without stepping on the brake, the car will power on but the engine will not start; 3. The duration of holding the one-button start key is not long enough or it is not pressed all the way. Frequently placing the car key near electronic devices such as mobile phones, computers, TVs, etc., can cause interference with the low-intensity radio waves in the key, or if there are strong radio waves nearby, such as from TV towers, airports, power plants, etc., the one-button start may malfunction.
