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?

What you're looking for is easily and cheaply available. The relevant keywords are "one sided deadbolt" or "keyless deadbolt".
Home Depot, for example, has a selection of them that start at $7.
If you already have a deadbolt you want to use, some companies sell a conversion kit to replace the keyway with a blank plate. Here's one from Kwikset. However, that's more expensive than just buying a new one sided deadbolt, so I'm not sure I see the point.
