Yep, you have to program the car once the new battery is installed. Don't ask why, I have no idea, but I got a battery replaced under warranty and asked if the dealer HAD to reprogram and they said yes. Might be just another way of getting paid but I didn't pay anything for it. I guess the warranty did.
