I can't recall what keyway it is exactly, but Emtek is a brand of fancy looking hardware like handlesets with deadbolts in decoroative trim, etc.
There shouldn't be anything fancy and it should pick much the same as Weiser, Kwikset, and others unless it has a different (Medeco or something) keyway.
Hope that helps.
Btw, how many pins and what does the key look like? Do your Schlage keys fit into this lock?
