(Car Analogy) - It's like leasing a car with a repair warranty and wanting to do your own repairs. You diagnose the cause of the problem and take the car to the mechanic. You ask the mechanic to fix your car under warranty and he asks you for your keys. You refuse to give him the keys.
I find your analogy to be somewhat flawed. A better analogy would be like the city or municipality forcing your car open when you don't hand over the keys after you've called to have your street repaired.
Repel them. Repel them. Induce them to relinquish the spheroid. - Indiana University fans' chant for their perennially bad football team
