how to disabl ekyeboard to play roblox

Here’s the quick fix: in Roblox, you usually can’t disable the physical keyboard itself from a game, but you can disable the keyboard actions so your character stops responding. A common Roblox scripting approach is to use ContextActionService to override movement keys like W, A, S, and D on the client.

What to do

1. Put a LocalScript in StarterPlayerScripts.
2. Bind the keys you want to block with ContextActionService.
3. Return Sink so Roblox ignores those inputs.

Example:

lua

local CAS = game:GetService("ContextActionService")

local function blockAction()
	return Enum.ContextActionResult.Sink
end

CAS:BindAction("BlockW", blockAction, false, Enum.KeyCode.W)
CAS:BindAction("BlockA", blockAction, false, Enum.KeyCode.A)
CAS:BindAction("BlockS", blockAction, false, Enum.KeyCode.S)
CAS:BindAction("BlockD", blockAction, false, Enum.KeyCode.D)
CAS:BindAction("BlockJump", blockAction, false, Enum.KeyCode.Space)

To turn it back on

Unbind the actions when you want controls restored:

lua

local CAS = game:GetService("ContextActionService")

CAS:UnbindAction("BlockW")
CAS:UnbindAction("BlockA")
CAS:UnbindAction("BlockS")
CAS:UnbindAction("BlockD")
CAS:UnbindAction("BlockJump")

Important note

This has to happen on the client , not the server, because keyboard input is handled locally. If your goal is just to stop movement, this is the safest route. If you only want to disable menu/controller-style navigation, Roblox also has a separate UI navigation toggle that can be switched off with the \ key in some cases.

TL;DR: you don’t disable the keyboard hardware — you block the Roblox inputs with a LocalScript using ContextActionService.
