I am planning a secondary entrance door that does not need to be openable from the outside. So, if I have a deadbolt on the door, I just need a twist lever on the inside and no lock on the outside.
When I look at deadbolts in catalogs, however, they all seem to have key holes and plates on the outside. Is it possible to just leave this part of the lock out, or do I need to find a deadbolt that is specifically designed to have just a lever on one side and no lock? If so, what is that called?
