Transponder Chips If your car was built in the last 20 years, then it has a transponder chip inside of it. It's a tiny piece of plastic inside the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own. When activated by an electro-magnetic field, the chip emits a low level signal. This signal then gets amplified by the specific antenna that is fitted around the ignition barrel of your vehicle.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer in the car recognizes the signal as being correct, it will disable vehicle immobilizer to allow the engine start.

When you press the button on a key fob the microchip transmits a signal to the receiver inside the car with which it is paired. The receiver compared the information with the permitted signals stored in the key fob and then opens or locks the car's doors. If the information doesn't match the signals, the car will not be allowed to drive. Once the car is linked with a particular fob, it will only receive signals from the device that is associated with it. As a result, other fobs won't work with the vehicle even if they have the same appearance. This safeguards the integrity of the computer system in the car and prevents the use of unauthorized key fobs to gain control over it. Most newer car dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer.
