I collected 99 keys in Ancient Egypt on the 1.6 update and apparently, that is where they max out. Collecting more keys will not increase the counter past 99. I believe this Pirate Seas's and Wild West's respective keys, though it will take a while to get 99 keys each for both. Stars may be different due to the finite nature of the amount of obtainable stars, but one would have to own the Chinese version of PvZ2 or pay to unlock Star Gates.
