The only difference between the tow handle sets is that the 82-081 has a keyed external handle, and the 82-080 dies not. The 82-081 uses our 82-310 key lock, which is a kwikset. Thanks for posting!

I think I need either your 82-080 or 82-081 but can't tell the difference. Also I notice you show a Schlage keyed lock. Can I get a lock keyed for Kwikset?
