How can I disable a seat for the player only?

I'm making a car and want only the owner to be able to drive it. I put a string value called 'Owner' inside the seat, the value of that is the owner. I then tried to deactivate the seat for the player if they were not the owner using a local script.

Is there some kind of issue regarding the local script?

script.Parent.Parent.Changed:Connect(function()
    local plr = game.Players.LocalPlayer
if plr.Name == script.Parent.Owner.Value then
    script.Parent.Disabled = false
else
        script.Parent.Disabled = true
end
end)

Thanks!
