When activated by an electro-magnetic field the chip emits a low-frequency signal. This signal is then absorbed by a special antenna attached to the barrel of ignition. The computer system of the vehicle will then confirm that the chip in the key's transponder is the right one for your car.

A circuit within the induction coil will emit a signal when the transponder is put into an ignition barrel. The signal will then get taken up by the chip, causing it to send a signal back to the car. If the onboard car computer recognizes this signal as the correct one, it will shut down the vehicle's immobilizer and allow the engine to start.
If the car doesn't recognize the transponder as a valid signal, it won't start the engine, and will notify you via flashing lights and an alarm.

There are many ways to program a key fob based on the model and make. You may be able to do it yourself, but most newer cars require that you visit an expert locksmith or dealer to program a replacement or additional fob.
When you press a key fob's button, the microchip inside transmits an encoded code to the car's receiver it is paired with. The receiver compared this information with the 'allowed' signals stored in the fob and then either opens or closes the door. If the information does not match the signals, the car will not be allowed to operate.
Once the car is paired with a specific fob, it only accepts signals from that device. Other fobs will not work with the car, even if they appear similar. This helps to protect the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control of the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. It is because the only place with the experience to design an appropriate replacement fob is a dealer's service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems can be programmed by customers without the need of dealers.
