What are the functions of the four buttons on the garage key?

Garage key with four buttons may vary in functions depending on the vehicle model. Generally, the basic functions of remote control keys include: unlocking the door, locking the door, activating the anti-theft alarm, and deactivating the alarm. Some remote controls have five buttons, with an additional one for remotely opening the trunk. Here is more related information: Key functions: Typically, the original remote key for a car has three buttons, which are for unlocking, locking, and opening the trunk. Depending on the vehicle's features, holding down the unlock button may also automatically open the windows (including the sunroof); holding down the lock button can automatically close all windows, and pressing the lock button twice can activate the anti-theft alarm while locking the doors. If the remote lock is installed later, it may not have integrated functions. Besides the lock and unlock buttons, there may only be a few additional buttons to perform their respective added functions, such as an alarm button, a discharge button, a remote start button, etc.
I use the four buttons on my garage remote every day. The large button at the top controls the main garage door—a single press raises or lowers the roller shutter. The small button in the bottom left corner operates the garage interior light, which is especially handy when fetching the car at night. The button in the bottom right is the lock key; holding it for three seconds activates the security lock to prevent tampering. There’s also a triangular-symbol button that controls the garden side gate, saving me from taking a long detour when picking up packages. The layout is very logical: thick buttons handle primary functions, while thin ones manage secondary features. Last time, my neighbor pressed the wrong button and left the garage light on all night, draining the battery completely.
As a frequent visitor to auto repair shops, I've studied various garage remote designs. The standard four-button remote typically allocates functions as follows: the main control button operates the door's up/down movement and occupies the largest space due to frequent use; the light button is placed separately to prevent accidental activation; the safety lock button prevents children's misoperation; the last button often serves as an extended function, sometimes controlling a secondary gate or courtyard lighting. The key is observing the indicator light color changes: green indicates signal transmission, while red blinking may signal low battery. Last year when helping a friend replace remote batteries, I noticed button positions vary across brands - it's best to photograph the original configuration for reference.
