A smart key could also make cars safer by not sending the exact same frequency signal repeatedly. If a key sent the same signal every time it unlocked a door or remotely opened the trunk, this would allow thieves who are tech-savvy to wire vehicles and remove them. Thankfully, this is not an issue since smart fortwo key fob keys emit a unique encrypted signal each when a door is opened or the trunk is opened remotely.

Smart keys also stop cars from being taken away by thieves at fueling stations and other parking lots. This is because they send a low-frequency signal that can be detected by the proximity of a smart key, however, not by any other person or objects outside of the vehicle.
