Keys, Doors and Windows 1-7 Remote Keyless Entry (RKE) System Operation (Keyless Access) The Keyless Access System transmitter functions will work up to 60 m (195 feet) away from the vehicle. The Keyless Access System lets you lock and unlock the doors and access the trunk without removing the remote transmitter from your pocket, purse, briefcase, etc. The keyless access transmitter must be within 1 m (3 feet) of the door or trunk being opened. Keyless Unlocking With the keyless access transmitter within 1 m (3 feet), approach the front door and pull the handle to unlock and open the door. 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 always cause all of the doors to unlock. This is not customizable. To customize which doors unlock when the driver's door is opened, see "Keyless Unlock" under Vehicle Personalization on page 4‑51. 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. It does not matter how far away that one transmitter is from the vehicle. To customize whether the doors automatically lock when you exit the vehicle, see "Keyless Locking" under Vehicle Personalization on page 4‑51. Keyless Trunk Opening Press the trunk release button located on the trunk lid above the license plate to open the trunk if the keyless access transmitter is within range. There are other conditions which can affect the performance of the transmitter. See Remote Keyless Entry (RKE) System on page 1‑4.
