Keyless Entry: Description and Operation

System Description

Keyless Entry System

The security alarm system is integrated with the keyless entry and multiplex systems. The passenger's multiplex control unit receives LOCK (arm) and UNLOCK (disarm), and Panic signals from the keyless entry control unit. The keyless entry system allows you to lock and unlock the vehicle with the remote transmitter. When you press the LOCK button, all doors lock. When you press the UNLOCK button once, only the driver's door unlocks. The other doors and the tailgate will unlock when you press the button a second time.

When the switch for the front individual light is in the center position (rear individual lights is in "door" position), they will come on when you press the UNLOCK button. If you do not open a door, the lights will go off in about 30 seconds, the doors will automatically relock, and the security system will rearm. If you relock the doors with the remote transmitter within 30 seconds, the lights will go off immediately.

You cannot lock the doors with the remote transmitter if a door or the tailgate is not fully closed, or if the key is in the ignition switch. If the tailgate or hood is not closed, the doors will lock and unlock, but the security system will not arm until the tailgate and hood are closed.

The system will signal you when the doors lock and unlock by flashing the parking lights, side marker lights, and taillights: once when they lock, and twice when they unlock.

When you press the LOCK button a second time within 5 seconds after you have locked the doors, the horns will sound once to verify that vehicle is secure and the security system will be set.

If the lights do not flash, make sure the doors, the hood, and the tailgate are closed and locked. The most common failure is a door, hood, tailgate, lock knob, ignition key, or door/tailgate key cylinder input. Check that the security indicator blinks. If the security alarm system does not arm, refer to the multiplex mode or security input tests.
