Keys, Doors, and Windows 2-7 Remote Keyless Entry (RKE) System Operation (Keyless Access) The Keyless Access System transmitter will work up to 60 m (195 ft) away. The Keyless Access System locks and unlocks the doors and trunk without pressing the buttons on the keyless access transmitter. The keyless access transmitter must be within 1 m (3 ft) of the door or trunk being opened. Keyless Unlocking With the keyless access transmitter within 1 m (3 ft), approach the front door and pull the handle to unlock and open the door. On some models there is a touch sensor on the door handle. If the transmitter is recognized, the door will unlock and open. To access the rear doors first, pull the rear door handle once to unlock all doors and a second time to open the door. Entering any door other than the driver door will cause all of the doors to unlock. This is not customizable. To customize which doors unlock when the driver door is opened, see "Keyless Unlock" under Vehicle Personalization on page 5￿48. Keyless Locking The doors lock after several seconds if all doors are closed and at least one keyless access transmitter has been removed from the interior of the vehicle. To customize if the doors automatically lock upon exiting the vehicle, see "Keyless Locking" under Vehicle Personalization on page 5￿48. To replace the battery: 1. Separate the transmitter with a flat, thin object inserted into the notch, located above the metal base. 2. Remove the old battery. Do not use a metal object. 3. Insert the new battery, positive side facing up. Replace with a CR2032 or equivalent battery. 4. Snap the transmitter back together.
