This receiver decodes the serial numbers that are generated by the transmission. If the number is in line the car's number, it will start. Transponder keys are used in all cars produced in the past two decades. They are also used on aircrafts. Air traffic control makes use of them to identify friendly aircraft by an encoded signal, IFF (Identification Friends or Foe).

Immobilizers Immobilizers provide an additional layer of protection against hotwiring. They prevent the engine from being started without ensuring that the transponder on the key fob is in order.

These systems are built around encryption of information that is sent between the transponder as well as the car's system.

These systems are superior to the traditional immobilizers, which use an unchanging code. The latest models use a technology that alters or rolls codes to ensure that the systems are secure. The issue with these versions is that hackers are still able to find ways to break the code, and then use a key to start your vehicle. To solve this issue the DST80 was developed with a more lengthy sequence to make it more difficult to guess. Researchers also managed to get it to work. It's essential to keep your keyfob with you, even when not using it.
