What the red LED alarm button is for?

Hi! Does anyone know what the red LED alarm button next to the USB port and lighter plug is for? The LED turns on when the ignition is turned on, and sounds a strange beeping that can be turned off when you press it. My friend had a test drive for the Coin Tray and didn't figure out what that button was for. We would appreciate any thoughts!

Is there an aftermarket alarm system installed on the vehicle, or nah?
