Last month I brought home a junkyard save 1981 Eagle sedan. It came with keys, but these were probably the next worst thing to not having any. They were so worn out, I don't know how they still worked.
The round one was slightly bent, and also cracked in the middle. I thought it would break in half if not handled carefully. The square one was marginally better.
I remembered George posting about how he had the equipment to produce "as new" keys based on nothing more than pictures of the old ones. So, I sent off a couple of pictures (which I didn't think were very good) and he said "I think I can do it".
Less than two weeks later, I had a pair of keys in the mail. I tried them and they both worked perfectly.
Huge thanks to George!
