Reply to Key 2 "Open Key"

Okay so i just started to use Keyfinder and because it doesn't have a setting to save in Open Key i decided to use the custom key codes to assign them to their open key. However, after scanning some songs i have found that Keyfinder detects most tracks differently to that of my previous software Beatunes. Would like to know if this is because of a shitty key analysis by Beatunes or if i have the wrong Key codes.
