Transponder Chips
If your car was built in the last 20 years, chances are it has a transponder chip inside of it. It's a tiny plastic piece on the back of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
reprogram car key sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna that is attached to the ignition barrel. The computer system of the vehicle will then confirm that the transponder chip of the key is the right one for your car.

A circuit inside the induction coil emits signals when the transponder is inserted into an ignition barrel. The signal will be received by the chip and cause it to transmit a signal to the car. If the computer onboard the car is able to recognize the signal as valid it will turn off the car immobilizer, allowing the engine to start.
If the car doesn't recognize the transponder as being the proper signal, it won't start the engine and will alert you with flashing lights and siren. This feature is designed to discourage individuals from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and determined criminal may still be able to get around this system using a device that can detect the signal.

Key fobs make use of radio frequencies to connect with one another and the car. The frequencies are transmitted through a small antenna located in the middle of the key. This communication is encrypted to block other key fobs from intercepting or replicating the signal.
There are several ways to program a key fob depending on your vehicle's model and make. You can sometimes do this yourself, but most newer cars require that you visit a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on a key fob the microchip sends an indication to the receiver inside the car that it is paired. The receiver compared this information with the 'allowed' signals on the fob and either locks or opens the door. If the data doesn't match, a chirping sound is heard and the car isn't allowed to function.
Once the car is associated with a particular fob, it only accepts signals from that device. In turn, other fobs won't be able to work with the vehicle even though they appear similar. This safeguards the integrity of the computer system in the car and blocks unauthorized key fobs gaining control over it.
Most newer car dealerships will only work with vehicles that have original fobs, or genuine replacements sold by the manufacturer. This is because the only place with the experience to design the replacement fob is the service department of the dealer. However, some fobs from the aftermarket typically for older models that have less sophisticated systems -- can be programmed by customers without the need of dealers.
