A smart key could also ensure the safety of vehicles by not sending the exact same frequency signal repeatedly. If a fob transmitted the same signal every time it unlocked a door, or remotely opened the trunk, this would allow tech-savvy thieves to use hotwires to drive them away. Smart keys emit a unique signal each time a trunk or door is opened remotely.

Smart keys also can help to stop cars from being stolen at gas stations or other parking spots. smart fortwo key fob keys send the signal at a low frequency that can only be detected by nearby smart keys, and not by objects or individuals that are not within the vehicle.
