When the key is inserted into the ignition, the car’s computer sends a signal to the chip; if the chip does not respond with the right code, the engine will not start.Switchblade Fobs: These systems combine the electronic remote and the physical key into a single folding part. They are commonly discovered on European designs like Volkswagen and Audi.Smart Keys (Proximity Fobs): These are the most advanced. They do not require a physical key to be inserted into a slot.

Replacement shells can be purchased inexpensively online to house the initial electronics.De-programming: Occasionally, a fob might lose its synchronization with the vehicle due to a deep battery drain. Some vehicles permit a simple “re-sync” procedure described in the owner’s manual.Contrast of Replacement Sources
