Pressing the lock button twice will arm the system immediately. If the vehicle is locked using the keyless access transmitter and the trunk lid, hood or a door is open or not closed completely, 108 the security light will flash for 60 seconds and then turn off. At this time, the theft-deterrent system is armed but the alarm will not sound if the trunk lid, hood or door that was not closed completely is tampered with or opened. The alarm will sound for the trunk lid, hood or a door that was completely closed at the time the vehicle was locked using the keyless access transmitter. • Open the door. Lock the door with the power door lock switch or lock button on the keyless access transmitter. The security light should flash. Close the door. The security light will stop flashing and stay on.
