Pet Simulator 99 – How To Get A Prison Key Surge
To get a Key Surge in Pet Simulator 99, you first need to look for the Big Police Chest. Now, you must break the big chest as many times as needed to start each Prison Key Surge. The number needed starts at 5 and then moves up each time you get a Prison Key Surge, but changes from time to time.

Watch the sign in the Police HQ to see how far you’ve come; when it’s done, you won’t need to do anything at all. Once you’ve filled up the bar, key drops will surge by 50% for 10 minutes.
Make sure to take advantage of these surges, and don’t worry about turning in keys until it’s over. The time you can waste turning keys in and trying to find places to use them is wasted when you consider that you could have gotten even more keys within that time. When the surge is over, feel free to do whatever you need to use the key.
