Most cars built in the last few decades carry an immobilizer, an electronic chip in the key that has to talk to the car before the engine will start. Real car thieves get around it with devices that clone or relay that signal. The name appeared in the September 2022 leak, pointing to a car theft tool built around that idea for GTA 6. Rockstar has not shown this item or explained how it might change vehicle theft in the game, so whether it speeds up stealing modern cars or unlocks a new theft animation is unconfirmed. It comes from leaked data rather than a trailer or a screenshot. Treat it as speculation until the studio says otherwise.
