Make groups of 4

1600 1404 1218 1010 1014 1216 1406 1600 1418 1412 1218 1012 1006 1000 1402 1410

You can see where the numbers should be in the passcode that the values are in the lower 1000s.

Each groups of 4 needs to be interpreted as 2 pairs. Divide each pairs by 2

80 72 69 55 57 68 73 80 79 76 69 56 53 50 71 75

Convert decimal to Ascii
