In Mayhem on Roblox, the lock-on key is usually the game’s target button rather than a universal Roblox setting, and one recent breakdown says pressing T selects the player you want to target.

Quick Scoop

From the available community info, the basic flow is:

  1. Get close enough to your target.
  2. Press the game’s lock-on/target key, often T in Mayhem-style combat breakdowns.
  3. Keep moving with the target so the camera and attacks stay aligned.

A separate Roblox PvP guide also describes lock-on timing as something you trigger while engaging, then use movement and dashes to stay on the opponent.

What it means

Lock-on in Roblox combat games usually means the camera or aim follows a chosen opponent so your attacks track better. In Mayhem, that seems tied to the game’s own combat system rather than a built-in Roblox feature.

If T does nothing, the game may have changed the keybind, or lock-on may only work in certain situations, such as when you are in range or actively fighting.

Practical tips

  • Try pressing T near a nearby opponent.
  • Stay mobile while locked on, because Mayhem combat emphasizes movement and dashing.
  • If the target keeps slipping off, re-center on the opponent and try again during combat instead of from far away.
  • Check the game’s current controls screen if the key changed in a newer update.

Safety note

Some search results about “lock-on” in Roblox refer to cheat scripts or aimbot-style tools, which are not the same as a normal in-game lock-on feature. Those are not a safe or fair way to play.

TL;DR

For Mayhem Roblox, the most likely answer is: move close to a player and press T to lock on , then keep fighting while moving and dashing.
