Sargent & Greenleaf Replacement Key Series SGR600 - SGR699

I expected the key identification to be stamped or engraved on the key, it was not. When I tried the keys (I ordered two), neither worked. The cut of the keys I received did not match each other, nor did they match the cut of the factory key for the lock. Very disappointed. I will be contacting Gus for a refund.

Not a match.
