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.
