I had this same thought the other day. For a lot of cars you can buy aftermarket programmers, but the Dorman ones are limited to 3 uses. 3 uses for like eighty dollars is terrible, and surely it's not a technical limitation.

Heh, maybe instead of circuit boards they are using wheat crackers.

		Hah, I hadn't considered a hardware approach to limited use. I assume there's just a counter in there. There could, theoretically, be cryptographic reasons it can only do 3 programming sessions, but I doubt it.
