Re: What am I getting myself into? Lock ID help, please

I've discovered that the change key I found in the safe was a bigger bonus than I first thought.
In the recent past, I came to find out that the change keys for the C87, M6730MP, and the R6730 were all slightly different. I worked around the differences on the C87 and M6730MP by modifying standard R6730 3-wheel U-8 change keys.
Notice the key on the bottom. That is the change key I found in this safe having the M6730 lock. The key on the top is a standard R6730 key (U-8). Notice the slightly different lengths on the working ends, and the fully machined notch on the key I found. It makes all the difference. The older, brass cases were dimensioned slightly different than the more current designs.
So, now I have the proper key for the C87 and M6730, but this key did not properly fit the M6730MP.
