Tom from SWISCO responded:

Your door handle uses the 82-310 key cylinder. These are kinda weird to work with; the keys they use are technically Kiwkset, but they sorta aren't at the same time. They're kind of their own thing. I don't know why they designed them that way, but a lot of locksmiths have trouble with it.

Fortunately, we sell a key blank made specifically for this lock. See our 82-322.
