locked keys Mod
locked keys Mod lets a server block chosen inputs such as WASD and mouse buttons, and freeze or unfreeze player movement, for cinematic or scripted scenes.
What it does
Locked keys Mod can block or unblock specific inputs, including the WASD keys and mouse buttons, and can freeze or unfreeze movement during a scene. A fixed cinematic camera stays in one position while the player still moves, jumps and rotates the view independently, which suits scripted moments and immersive events.
The mod is a client-side mod, so only the client needs it, but it works only when a server plugin supplies the control signals. Its author describes it as a way for servers to take full control over player inputs and camera, for spectator systems, custom gamemodes and advanced server experiences.
The build targets 1.21.1 only and is published for Fabric. It is released under All rights reserved and is not open source, and the 1.0.0 file is dated 2026-03-25.

Use cases
Cutscenes
A server can lock the camera and movement while a scripted event plays out in front of the player.
Custom gamemodes
Server owners can restrict inputs to build modes where players follow fixed rules.
Who it’s for: Server owners and map makers who script cinematic events or custom gamemodes that need control over player input. The mod needs a server plugin to send the control signals, so it is of little use on a server that does not run one.
How it compares
Locked On is open source under the MIT License and targets Fabric for 1.21 – 1.21.5, so it covers older builds than this mod. Cinematic Flashlight is also client-side only for 1.21.1, but it is released under All rights reserved and is not open source. easy-cutscene is server-side only for 1.21.4 and uses All rights reserved, so it runs without any client install.
