How to Use the Hold Button on Car Key?

[SanAdeline]

The hold button on the car key is used as follows: 1. It usually means long press. Some have a trunk pattern printed on them, indicating that a long press will open the trunk, simplifying the process of opening the trunk after opening the car door. 2. The hold button is also a remote engine start button. Within a remote distance, press and hold for 2-3 seconds, and the car will start automatically. This function can be used to adjust the interior temperature in advance during winter and summer. When remotely starting the engine, there is no need to worry about car theft because the central locking system in the car door remains locked. The remote control range is usually no less than 50 meters, allowing you to start the vehicle remotely from home or work. Due to the automatic timing function, if the car door lock is not opened within a certain time, the car engine will automatically shut off.
