How to Use the Pet Simulator 99 Key Master Macro

How to use the AHK Vault Key Master macro in Pet Simulator 99: where to start, which keys it uses and combines, and what each setting does.

Key takeaways

Start in the spawn world, standing at spawn.

Choose whether to use keys, combine keys, or both.

It travels between the Tech, Void and Fantasy worlds, so you need all three unlocked.

You can pick exactly which keys are used and which are combined.

1. How to Start

Load into the spawn world in Pet Simulator 99 and stand at spawn. Open AHK Vault, choose Pet Simulator 99, launch Key Master, set it up, then press F1. F2 pauses and F3 exits.

2. Modes

The Modes tab has three options:

  • Use keys: opens keys from your inventory.
  • Combine keys: combines your keys.
  • Combine all at once: combines everything together instead of one at a time.

The macro travels between the Tech, Void and Fantasy worlds to handle each key type, so you need all three worlds unlocked.

3. Choosing Keys

  • Keys To Use: Crystal, Tech, Void, Fantasy and Mvp.
  • Keys To Combine: Crystal, Tech, Void, Fantasy, Secret, Mvp and Treasure.

Untick any key you want to keep. The hotkeys can be changed at the bottom of the same tab.
