Unlocking
Press unlock button once for left door. Press and hold for .5 seconds for both or press twice. Turn signals flash twice, and horn chrips twice. If chrips 5 times then there is a problem with the door lock. If lock system is overloaded, power supply is cut for 30 seconds. If they flash three times (the lights) when pressing unlock, then an attempted break-in has occurred (turn ignition on, look at trip computer display for the ALARM ACTIVATED message. They will show until the trip computer MODE button is pressed).
