Keys, Doors, and Windows Passive Locking If equipped with Keyless Access, the vehicle will lock several seconds after all doors are closed if the vehicle is off and at least one transmitter has been removed or none remain in the interior. If other electronic devices interfere with the RKE transmitter signal, the vehicle may not detect the RKE transmitter inside the vehicle. If passive locking is enabled, the doors may lock with the RKE transmitter inside the vehicle. Do not leave the RKE transmitter in an unattended vehicle. Temporary Disable Passive Locking Feature Temporarily disable the passive locking by pressing and holding K on the interior door switch with a door open for at least four seconds, or until three chimes are heard. Passive locking will then remain disabled until Q on the interior door is pressed, or until the vehicle is turned on. To customize the doors to automatically lock when exiting the vehicle, see "Remote Lock, Unlock, Start" under Vehicle Personalization on page 5-45. Keyless Trunk Opening Lift up on the touch pad above the license plate to open the trunk if the RKE transmitter is within 1 m (3 ft). 2-5 Programming with a Recognized Transmitter (Key Vehicles Only) To program a new key: 1. Insert the original, already programmed key in the ignition and turn to the key to the ON/ RUN position. 2. Turn the key to LOCK/OFF and remove the key. 3. Insert the new key to be programmed and turn it to the ON/RUN position within five seconds. The security light will turn off once the key has been programmed. 4. Repeat Steps 1-3 if additional keys are to be programmed. If a key is lost or damaged, see your dealer to have a new key made. Programming Transmitters to the Vehicle Only RKE transmitters programmed to the vehicle will work. If a transmitter is lost or stolen, a replacement can be purchased and programmed through your dealer. The vehicle can be reprogrammed so that lost or stolen transmitters no longer work. Any remaining transmitters will need to be reprogrammed. Each vehicle can have up to eight transmitters matched to it.
