Allows the user flexibility on how to manage entry – by key, code

models will lock out code users when appropriate. A safety feature
ensures that the inside lever handle will retract the deadbolt so as
to avoid accidentally locking a person inside the room. Front and
back plates can be purchased for use with existing locks.
