What does the 'hold' on the car key mean?

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.

Last time I helped my neighbor understand this feature, and she's been using it effortlessly every day to pick up her kids. 'HOLD' essentially means you press and hold with your finger to perform a special function. For example, in her Toyota, when she's carrying her child's backpack with both hands, she can bump the car door with her knee and press the 'HOLD' button next to the unlock button on the key fob for three seconds with her thumb—then the trunk pops open with a 'click.' Some luxury cars are even smarter; holding the lock button will automatically fold the side mirrors. Just be careful with cars like Lexus—you need to apply enough pressure, or it won't trigger. It's especially handy during the rainy season. When the parking garage is far from the building entrance, holding the window button can air out musty smells in advance. Now, my neighbor has taught her kid how to use it—after P.E. class, they just toss their used sneakers straight into the trunk.

Having played with car modifications for over a decade, the 'HOLD' function on the key fob is arguably the most underrated feature. Those who've disassembled key fobs know - beneath the buttons lie contact switches paired with delay circuits. In practice, it's brilliantly simple: for instance, holding the lock button in a parking lot triggers continuous horn honking to locate your car. The real game-changer is during summer parking - a 5-second hold on the unlock button drops all windows simultaneously for pre-ventilation. The only caveat is that some older models require an initial unlock press before the long-press works. This feature becomes indispensable for stance builds - when air suspension is wired up, 'HOLD' programs different lift/drop modes. Pro tip for EV owners: prolonged pressing activates the charge port cover on certain models.
