What does the 'hold' on the car key mean?
2 Answers
Car key's 'hold' is the hold mode, different from unlocking and locking. Opening the trunk only requires operation after parking. The function of holding the 'hold' button for a few seconds to open the trunk is to avoid the danger of opening the trunk by pressing the 'hold' button while the vehicle is moving. The working methods of car keys are: 1. Active working method: The principle is to control the door through the body electronic module and the body control module. Just press the key button to send the unlock/lock command; 2. Coil induction working method: Mainly by placing an encrypted chip in the key, during the unlocking process, the body's RF transceiver verifies whether the key matches to decide whether the engine can be started.
I always enjoy figuring out these buttons while driving, and the 'HOLD' on the key fob is incredibly practical. Simply put, holding it down triggers special functions, with different brands offering different features. For example, with my Hyundai, holding 'HOLD' while the car is locked automatically opens all four windows and the sunroof. In the summer, I press it from a distance before getting in, letting all the hot air escape. Volkswagen models usually have a trunk icon with the word 'rear'—holding it pops open the trunk for loading. As for American cars like Ford, holding the button with an arrow can remotely start the engine. Just remember, this feature drains the battery quickly; the key fob battery needs replacing every six months, or it might suddenly stop working, which can be a hassle. The funniest moment was when a friend locked their dog in the car and used the long-press window feature as an emergency solution, only to have documents from the storage compartment blown everywhere by the wind.
