Pet Simulator 99 – How To Combine Prison Keys

Go find Prison P in the Prison Courtyard in Pet Simulator 99. He will take your 10x regular keys and swap them for a single golden prison key. The game warns that he may steal a few, but we’ve not found that to be the case. So far, he’s only taken 10 of my keys and given me a golden prison key for my trouble.

If you do notice he takes some, that may be a mechanic. Prison P is an inmate, so he’s a criminal, obviously criminals can’t be trusted so it’s a good way to remind players.

It’s also important to keep in mind that any key you convert doesn’t count towards the clan battle or global event. So don’t think your numbers will go up as if you originally got a golden key. The swap is exclusive to help you unlock anything you need, not for the battles going on.
