I'm pretty sure more than a decade ago my dad had a keyless entry fob for a car, who's make I do not recall, that had a sticker to discourage battery replacement. This anecdote is only relevant in the sense that the sticker might not be on the hood of the car; remote control for AV system or keyless entry or tire pressure monitoring gadgets inside the wheels are definite possibilities.
