For personal use?
I've read this here:
http://forum.doityourself.com/residential-commercial-security-locks-keys-dead-bolts/395691-weiser-kwikset-schlage-question.htmlA lock's brand name is usually stamped into the latch plate. If there is no name, it's usually a made-in-China el cheapo.
These mostly use the Schlage "C" keyway or the Dexter/Kwikset keyway.
By "compatible" I assume you mean similar keyway, so as to fit one key to all locks. Generally, a Kwikset key can be made to fit a Weiser lock, but not vice-versa. Neither is compatible with Schlage. In SOME cases, aftermarket cylinders can be ordered from your local locksmith to fit into SOME types of locks.
