Family lost the old key to the smokehouse (1700's or early 1800s's) where the freezer and tools were! Locksmiths couldn't make the key as it was too large...so a family friend who was a hobbyist blacksmith made the key.

They should have had two made so the next time the key gets lost they have an extra as back-up.

The lock key was a simple square? how would you know that? All the old skeleton keys i've scene have some sort of pattern to them.
Hmm...Now i need to find an old lock and see what's in there..

I did a job like that about 6 or 7 years ago. Took a few hours to forge the key. Big difference was I got paid $250 to do it. Learning how to make a key when you have never done it before is hard.
