Keymaster: What type of keyway?
The description indicates that you could have the gimmick(s) cut by a locksmith or hardware store, so they'd actually WORK as keys for -- say -- your home. Of course not all key blanks fit all locks. And there are literally hundreds of incompatible brands, the top five being KWIKSET,
SCHLAGE, TITAN, MASTER and WEISER. Is it one of those and if so, which one?
