How to farm keys easily to use on multiplayer (for the people who are gonna down this tip keys only exist on ark ume)

1. Go to singleplayer

2. Go to carno island

3. Loot a supply crate and hope it gives you keys (they have a chance to give around 5-10 keys each)

4. Quit and rejoin your game

5. Once your game loads, wait until another supply crate spawns (will take like 15 seconds, they will always spawn on carno island so you won't have to fly miles to the next one

6. Loot it and go back to step 4 until you are rich in keys, this is faster than waiting 24 hours for the daily reward
