Theory Of Operation

The secondary lock is a dead bolt that prevents the door from being opened when the vehicle has been armed. It can only be locked when the key is out of the ignition, all doors are closed, the front door ajar switch transition has been completed and the RKE fob is pressed in the armed position. The secondary lock will operate approximately 18 seconds after the door latches are locked. The secondary locks are unlocked by a RKE fob unlock command after approximately 375 ms later than the door latches. They will also unlock when a valid SKIM key is turned to the ON position or the vehicle is driven and reaches Auto Door Lock (rolling) status. This system is only used on Right Hand Drive vehicles.
