Transponder keys are a type of key that use microchips to transmit a low-level RFID signal from the key to the receiver. If the receiver recognizes the serial number, the door is open. These keys are specifically designed with unique serial numbers, making it nearly impossible to copy them. Transponder keys are used in cars and cannot be copied because an internal computer chip sends an encrypted code.
These chips are programmed to prevent duplication and the codes cannot be deciphered with any existing instrument. They use resistors and have a built-in electrical modification. If the value of the current entered into the memory with a given engine wrench does not match that of the installed resistor, the car will not start.
