I've just lost the key to one of my outer doors - the only copy. It's a mortise type, not a Yale, and it's *very* simple: just two prongs, of equal length, and of 'maximum' length (ie: as long as the blank itself) and as far apart as possible (ie: right at either end of the blank). The lock, therefore, is *probably* a two-lever job.
So, if I gave a key-cutter a tracing of the keyhole, and the thickness of the door, could s/he cut a key without seeing the original?
Thanks in advance
Sue
