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!
