2-12 Keys, Doors and Windows Arming with the RKE Transmitter The alarm system will arm when you use your RKE transmitter to lock the doors, if the key is not in the ignition. Once armed, the alarm will go off if someone tries to enter the vehicle without using the RKE transmitter or a key or turns the ignition on with an incorrect key. The horn will sound and the turn signal lamps will flash for about 30 seconds. When the alarm is armed, the trunk may be opened with the RKE transmitter. The power door lock switches are disabled and the doors remain locked. You must use your RKE transmitter or your key to unlock the doors when the system is armed.
