Transponder Chips
If your car was built within the last 20 years, it is likely that it has a transponder inside of it. This is the little piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your vehicle.
When activated by an electro-magnetic field, the chip emits a low level signal. This signal is then absorbed by the special antenna that is positioned around the barrel that controls your ignition in your car. The computer system of the vehicle will then confirm that the key's transponder chip is the correct one for your vehicle.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the computer in the car recognizes the signal as being correct, it will disable vehicle immobilizer so that the engine can start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and will alert you with flashing lights and siren. This feature is intended to discourage people from trying to hack into the vehicle, but it's not a 100% security measure.

When you press a key fob's button, the microchip inside transmits an informational code to the car's receiver it is linked to. The receiver then compares this information to the signals that are allowed in the fob and then either opens or locks the door. If the information does not match the fob's information, the car won't be allowed to operate.
After the car has been connected to a specific fob, it can only receive signals from the device. Other fobs will not work with the car, even though they appear similar.
