Unbinding keys[UNANSWERED]?

For a while I was wondering how to disable some of the Humanoid Controller Keys . Every time I bind or unbind keys, the whole Roblox Studios Crashes.

EDIT1: Also I don't want to disable all the Controls, is there a way to to disable certain Controls?

EDIT2:

game:GetService("ControllerService").Instance:UnbindButton("w") -- Why won't it Unbind from Humanoid Controller.

I couldnt find anything wrong, Its all Good, Also Im New To The Unbinding Keys Thing, Good Luck Though.

I'm not sure if this will work, but you might as well try.

for _, v in pairs(game:GetService("ControllerService")) do 
	if v:IsA("HumanoidController") then --You probably need to check for a HumanoidController first
		game:GetService("ControllerService").Instance:UnbindButton("w")
	end
end
