A multifunction vehicle security system, which includes a receiver connected to a control unit which processes received information and enables various functions. The user can increase or decrease the sensitivity of the system sensor, by merely pressing a button on the remote control to increase the sensor sensitivity, and another button to decrease the sensitivity. A special programming mode resets the system programmable features and values to factory settings, to quickly re-establish to a known state all or only preselected features. The system provides automatic silencing during night conditions of the system's arming/disarming chirping to confirm the change of system state. The security system generates a door unlocking command to the vehicle's power door locking system to unlock the doors in the event of a vehicle collision. A theft warning LED energy management system conserves battery power when the vehicle is left unattended for long periods of time. When the system is armed, a timer is started, and upon expiration of a time period, the LED activation duty cycle will be reduced from an initial duty cycle. The polarity of the door locking and unlocking signals is programmab…
