Security Smart keys are key fobs that are computerized and communicate with a vehicle through one of the antennas built into the car to unlock doors and start the engine.

This makes it more difficult for tech-savvy thieves to steal or spoof the signal and use the key to steal your car. For example, Mercedes' system -known as Keyless Go — has an internal transponder that can identify the driver's key.
