Yeah, it would be our luck everyone sticks to the C D E F ranges and the key is in the 8 range lol
Highly unlikely it would be in the 8 range. So far with all the found keys there have been no duplicates. Beginning with 137 only 8 and B have been used, therefore if anything it's more than likely in either 9, A, C, D, E, F ranges.
