Transponder Chips
If your car was built within the last 20 years, then it has a transponder chip inside of it. It's the small piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna that is attached to the ignition barrel. The computer system in the vehicle is then able to verify that the chip in the key's transponder is the correct one for your car.
This is what prevents doing hot-wiring or altering the vehicle's ignition system to get it started. The chip inside the key verifies that the owner is the one who is the owner of the vehicle. This helps to prevent car theft.
Transponder keys resemble regular keys made of metal, but with caps made of plastic. The chip is located inside the plastic portion of the keys. There are several different cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal will then get taken up by the chip and cause it to transmit a signal back to the car. If the computer onboard the car detects the signal as being correct, it will disable vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and alert you with flashing lights and siren. This is designed to discourage people from attempting to alter the vehicle, but it's not a 100% security measure. A skilled and determined criminal could still be able to get around this system employing a device designed to intercept the signal.

When you press a key fob's button the microchip inside sends a code to the car's radio that it is paired with. The receiver compares the information with the 'allowed signals' that are stored in the key fob, and then locks or opens the car's doors. If the information isn't in line, a chirping sound is heard and the car isn't able to operate.
Once the car is associated with a particular fob, it can only receive signals from the device. Other fobs will not work with the car, even if they look like. This is to safeguard the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle.

This is because the only place that has the expertise to prepare an appropriate replacement fob is a dealer's service department. However, some aftermarket fobs typically for older models that have less sophisticated systems can be programmed by customers without the need for dealers.
