The phrase “limit key” in Roblox most likely means a Limitless Key in the game Sailor Piece. The fastest way people are getting it is by farming the Gojo boss at Shibuya Station or farming strongest sorcerer mobs on Shinjuku Island, which also drop it.

How to get it

  • Go to Shibuya Station and beat the Gojo boss repeatedly for a high drop chance.
  • Farm the strongest sorcerer mobs on Shinjuku Island ; they can drop Limitless Keys too.
  • A lot of players combine both methods: boss farming for speed, mob farming for steady progress.

If you meant Roblox scripting

If you meant a Datastore key limit or how to handle keys in Roblox code, Roblox dev discussions note that the main restriction is on value size and request limits rather than a simple “key count” limit.
