Just a tip: The more exotic the key/lock the more likely the name on the key is from the actual manufacturer (they closely control the key stock for these sorts of locks). However the key for a pin-tumbler Kwickset, which are as common as dirt in the U.S. (and about the same quality ), might well have almost any name on it or none at all. Heck, it may even be painted with the logo from the local football team or a flag.

I found that my friend's kwikset lock said "TITAN" on the face of deadbolt, but had kwikset mounting hardware. The ironic thing is that his kwikset is protecting a $500,000 house.
