What does 'hold' mean on a car key?

hold on a car key means hold mode. Here is the extended information: 1. The function of hold is to keep the vehicle in a specific gear range, driving our car like a manual transmission. For example, when the car is driving in third gear, pressing the hold switch (displayed on the instrument panel) will make the car only drive in third gear. 2. The working methods of car keys can be divided into three categories according to their usage: active working mode, passive working mode, and coil induction mode. 3. Active working mode. The principle is to control the door through the body electronic module and the body control module. Simply press the key button to send an unlock/lock command, and after verification by the body electronic module, the door can be opened/closed. 4. Coil induction working mode. Mainly by placing an encrypted chip inside the key, during the unlocking process, the vehicle's RF transceiver verifies whether the key matches to decide whether the engine can be started. It is mainly used in special cases when the key is out of power, the car can still be started normally. 5. Passive working mode. When entering the sensing area of the key system, as long as the hand touches the door handle, the carried 'key' will receive the low-frequency signal sent by the car. If this signal matches the identification information stored in the 'key', the 'key' will be awakened.
The 'hold' on a car key refers to the operation of pressing and holding the button. When I use the key, a short press usually only locks or unlocks the car, but a long press may activate additional functions. For example, holding the unlock button on my car key for a few seconds automatically opens all the windows, which is very convenient for ventilation on hot days; holding the lock button may close all windows or activate the anti-theft alarm. This functionality is mainly designed to provide a secondary operation to avoid accidental short presses causing issues. I find it quite practical, especially when forgetting to close the windows and being able to handle it remotely, but be careful not to accidentally activate it by holding the button in your pocket. Different car models may have slight variations in details—my SUV has this customized setting, so it's advisable to check the manual for confirmation.
