The transponder signal is received by a detector near the ignition that decodes the serial number of the transmission. If the number is in line, the car starts. Most cars built in the past two decades use transponder keys. They are also used in aircrafts. Air traffic control makes use of them to identify friendly aircraft through the use of a coded signal called IFF (Identification friend or foe). Certain aircrafts have mode C or mode S transponders that transmit identifying codes as well as altitude information to ATC. They also provide systems to avoid collisions.

Hackers can break them by analyzing the messages that are transferred back and forth across the CAN bus. These systems are much more advanced than the conventional immobilizers, which rely on a fixed code. The newer models feature the capability of changing or rolling codes to make them more secure. Hackers are still able to crack these codes and use keys to start your vehicle. To address this issue, the DST80 was developed with a longer sequence to make it more difficult to determine. Researchers also managed to solve it. It's essential to keep your keyfob in your pocket even when you're not using it.
