When the key is placed into the ignition, the car’s computer system sends out a signal to the chip; if the chip does not react with the right code, the engine will not start.Switchblade Fobs: These units combine the electronic remote and the physical key into a single folding component. They are frequently discovered on European models like Volkswagen and Audi.Smart Keys (Proximity Fobs): These are the most innovative. They do not need a physical key to be placed into a slot.
