What do the four buttons on the car key mean?

[McAnthony]

Generally, the four buttons on a car key represent the following functions: unlock, lock, open trunk, and find car. 1. Unlock button: a. Pressing the unlock button once only opens the driver's door; pressing it twice unlocks all four doors. b. Holding down the unlock button for several seconds will simultaneously lower all four windows. Some models may also open the sunroof. 2. Lock button: This commonly used button locks all four doors when pressed. It also has a hidden feature: remote window closing. 3. Trunk release button: The key has a trunk opening button. For some vehicles, holding this button or pressing it twice will automatically pop open the trunk. Certain models with proximity keys can open the trunk by making a kicking motion under the rear bumper. 4. Find car button: Some keys feature a red button with either a horn symbol or the word "Panic" – technically called the "find car button." As the name suggests, this function uses remote or alarm systems to activate the car's horn and hazard lights when pressed, making it easier to locate your vehicle in crowded parking areas.
