Why does this script do nothing, even tho its supposed to do something? no errors

I made a spawner, but when i click G, it wont do anything.

first script (at the startergui):

local uis = game:GetService("UserInputService")
local plr = game.Players.LocalPlayer
local name = plr.Name..("'s Car")
local debounce = false
uis.InputBegan:Connect(function(key)
	if key.KeyCode == Enum.KeyCode.G then
for i,v in pairs(game.Players.LocalPlayer.Character:GetChildren())do
	if v:IsA("Model") and v.Name == name then
	v:Destroy()

	end
	end
	end
end)
uis.InputEnded:Connect(function(aey)
wait()
game.ReplicatedStorage.SpawnCarEvent:FireServer()
end)

second script(at the workspace):

local debounce = true
local uis = game:GetService("UserInputService")
game.ReplicatedStorage.SpawnCarEvent.OnServerEvent:Connect(function(plr)
	uis.InputBegan:connect(function(aey)
		if aey.KeyCode == Enum.KeyCode.G then
			if not debounce then
			wait()
		 local car = plr.SelectedCar.Value:Clone()
		car.Parent = game.Players.LocalPlayer.Character
		car.Chassis.Base.Anchored = true
		car.Name = plr.Name..("'s Car")
		car:SetPrimaryPartCFrame(plr.Character.Head.CFrame * CFrame.new(0,0,-10))
		car:MakeJoints()
		car.Chassis.Base.Anchored = false
		debounce = true
		wait(0.1)
		debounce = false
			end
			end
		end)
end)

thanks for helping!

Your second script is where the problem is at

"not" will reverse the boolean value , your debounce at the beggining is true, so when you put if not debounce then it means if false then, which of course will not run as the value is false

Also you UserInputService doesnt work in server scripts

local debounce = true

game.ReplicatedStorage.SpawnCarEvent.OnServerEvent:Connect(function(plr)

      
            if debounce then
            wait()
         local car = plr.SelectedCar.Value:Clone()
        car.Parent = game.Players.LocalPlayer.Character
        car.Chassis.Base.Anchored = true
        car.Name = plr.Name..("'s Car")
        car:SetPrimaryPartCFrame(plr.Character.Head.CFrame * CFrame.new(0,0,-10))
        car:MakeJoints()
        car.Chassis.Base.Anchored = false
        debounce = true
        wait(0.1)
        debounce = false
       
            end

end)
