To cancel the rear door security lock, do the following: 1. Unlock the door and open it from the outside. 2. Turn the knob to the horizontal position to disengage the lock. 3. Do the same for the other rear door. Lockout Protection If the key is in the ignition and the power door lock switch is used to lock the doors, all doors will lock and then the driver's door will unlock. It is always recommended that you remove the ignition key when locking your vehicle. The lockout protection feature can be overridden by holding the power door lock switch for three seconds or longer. 101
