Another way that smart keys keep vehicles safe is by not sending the same frequency signal repeatedly again. If a smart key sends an individual signal each time it opened or locked a trunk remotely, it could allow thieves to wire cars to eliminate them. Smart keys emit a different signal each time a trunk or door is opened remotely.

Smart keys also stop cars from being stolen by thieves at fuel stations as well as other parking spots. Smart keys send a low-frequency signal that can only be picked up by nearby smart keys, and not by people or other objects outside the vehicle.

It's a tactic referred to as a relay attack, and it has been used by thieves with the latest technology to steal cars from drivers at fueling stations, and also in parking lots.

Most smart key systems do have a backup system for opening and starting the vehicle in the case of an insufficient battery. The driver will usually put the dead key fob in the slot, or place it close to a special area in the cabin to trigger the emergency starting system. This usually involves an inductive coil which transfers energy from the key to the car.
