To deter theft of the vehicle, this system is designed to
sound an alarm if any of the doors, trunk or hood is
forcibly unlocked or opened or the battery terminal is
disconnected and then reconnected while the vehicle is
locked.

also turn on.
After the alarm is activated, when you unlock any door or the
