Rear Door Security Locks (Crew Cab) If the vehicle is a crew cab model, it may have rear door security locks. With this feature, the rear doors are locked so they cannot be opened from the inside. The rear door security lock is located on the inside edge of each rear door below the security lock label. To open a rear door when the security lock is on, unlock the door and open the door from the outside. To disengage the security locks: 1. Open one of the rear doors. 2. Using the ignition key, turn the lock to the vertical position. 3. Close the door. 4. Repeat these steps on the other rear door. Lockout Protection If the vehicle has power door locks, this feature protects you from locking the key in the vehicle when the key is in the ignition and a door is open. If the power door lock switch is pressed when a door is open and the key is in the ignition, all of the doors will lock and then the driver door will unlock. To engage the security locks: 1. Open one of the rear doors. 2. Using the ignition key, turn the lock to the horizontal position. 3. Close the door. 4. Repeat these steps on the other rear door. 2-8
