The remote keyless entry transmitter is used to arm/disarm the theft-deterrent system. Your vehicle's theft-deterrent system can be programmed to three different modes.

Active Arming: The system will arm when the lock button on the remote keyless entry transmitter is pressed. The system will disarm when the unlock button is pressed.

Passive Arming: The system will arm itself one minute after the ignition is turned off and the driver's door has been opened and closed. If the lock button on the transmitter is pressed before the minute has passed, the system will arm immediately. The system will disarm when the unlock button is pressed.

Security System Disable: The system will not arm.

To change the mode that your vehicle is programmed to, do the following:

  1. Turn the ignition to RUN or ACC.
  2. Press the panic alarm button on the transmitter slowly four times within five seconds.
  3. You must complete one of the following within three seconds to change the mode.
  4. • To select the active arming mode, press the lock button on the transmitter.
    • To select the passive arming mode, press the lock button on the transmitter twice within 3 seconds.
    • To select the security system disable mode, press the unlock button on the transmitter.

A chime will sound once the mode has been selected.

If you accidentally set off the alarm when entering/exiting the vehicle, you can shut it off by pressing any button on the remote keyless entry transmitter other than the panic alarm button.

If you hear three horn chirps when you press the unlock button on the transmitter, that means the vehicle's alarm was triggered while you were away.
