Keyless Entry System
SmartKeys include Keyless Go unlock or start your car even when you don't have the key. This is achieved by with a technique called passive entry and go. The SmartKeys come with an RFID chip that allows the vehicle's computer to identify a driver when it detects the key at close range.
The key transmits low-frequency signals that are picked up inside and outside the door handles. If the transmission matches ID on the PASE module (Passive Access and Security Electronics) the system will allow that the key act as a passkey to operate the vehicle.
These systems are designed to prevent "replay attacks" which could permit a hacker to record and replay control signals and then use them to gain access to a car or building. To stop this from happening, a specially designed algorithm ensures that each transmission transmitted by the keyfob is different from previous ones. This means that if someone records one of these transmissions, and then attempts to duplicate it, the car's PASE module will be alerted and deny access.
