Transponder Chips
If your car is made within the past 20 years, then it has a transponder inside of it. It's the tiny plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is then taken up by an antenna attached to the barrel of ignition. This allows the computer in your vehicle system to determine if the transponder chip in the key is the right one for your specific vehicle.
This is what prevents from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip inside the key also proves that you are the legitimate owner of the vehicle. This will help reduce car theft.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal will then get absorbed by the chip and cause it to send a signal back 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 does not recognize the transponder signal as being the right one, it will keep the engine from starting and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage people from trying to hack into the vehicle, however it is not a foolproof security measure.

There are many ways to program a key fob based on your vehicle's make and model. You may be able to do it yourself, but the majority of newer vehicles require a locksmith shop or a professional to program a replacement or additional fob.
When you press the button on your key fob it transmits a code to the car's receiver it is paired with. The receiver compares this information with the 'allowed' signals in the fob and then either opens or locks the door. If the information doesn't match the signals, the car will not be allowed to drive.
Once the car has been connected to a specific fob, it can only receive signals from the device. In turn, other fobs won't work with the vehicle even if they have the same appearance. This protects the integrity of the computer system in the car and blocks the use of unauthorized key fobs to gain control of it.
