Keyless Entry: Description and Operation

System Description

Keyless Entry System
The security alarm system receives lock (arm), 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 push the LOCK button, all doors lock. When you push the UNLOCK button once, only the driver's door unlocks. The passenger's door will unlock when you push the button a second time. The two keyless remote transmitters also activate the Driving Position Memory System (DPMS). Each transmitter is coded to send either the Memory 1 or Memory 2 signal to the DPMS control unit. The code is marked on the rear of each remote transmitter. The feature can be turned off by pressing the LOCK and UNLOCK buttons on the transmitter at the same time, and waiting for the LED on transmitter to blink twice. To turn the feature back on, press and hold the LOCK and UNLOCK buttons at the same time, and the LED will blink once.
The ceiling light, if its switch is in the center position, will come on when you press the UNLOCK button. If you do not open a door, the light 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 light will go off immediately.
You cannot lock or unlock the doors with the remote transmitter if a door is not fully closed, or if the key is in the ignition switch. If the trunk or hood is not closed, the doors will lock and unlock, but the security system will not be armed until the trunk lid and hood are closed. To open the trunk lid, push the Trunk Release button and hold it for about two seconds. The trunk lid will not open if the key is in the ignition switch. 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 horn will sound once to verify that the security system will be set.
