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 door will unlock. It is always recommended that the ignition key is removed from the vehicle when locking the doors.
The lockout protection feature can be overridden by holding the power door lock switch for three seconds or longer.
