Transponder Chips
If your car is made within the last 20 years, it is likely that it contains a transponder chip within of it. It's the small piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your car.
When activated by an electro-magnetic field the chip emits a low-frequency signal. This signal is then received by a specific antenna attached to the barrel of ignition. This allows the vehicle's computer system to determine if the transponder chip that is in the key is the right one for your particular car.
This is what stops doing hot-wiring or altering the ignition system of your vehicle to start it. The chip in the key also verifies that you are the legitimate owner of the vehicle. This will help reduce car theft.

A circuit inside the induction coil will emit a signal when the transponder is inserted into ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer inside the car recognizes the signal as correct it will turn off the car immobilizer so that the engine can start.
If the car does not recognize the transponder signal as the correct one, it will prevent the engine from starting and will alert you by flashing its lights and sounding siren. This function is designed to discourage individuals from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and committed thief could still be able to escape this security system by using a special device to take over the signal.

Many of these extra features may seem convenient but they could make it harder for you to keep the keys to your car.
Key fobs use radio frequencies to communicate with one another and the car. These frequencies are sent through a small antenna located in the middle of the key. This signal is encrypted to stop others from intercepting or replicating the signal.
There are a few different ways to program a key fob depending on the model and make. It is possible to do this yourself, however most modern automobiles require a dealer or professional locksmith to program a replacement or additional fob.
When you hit the button on a key fob, the microchip inside transmits a code to the car's receiver that it is linked to. The receiver compares this information with the 'allowed' signals stored inside the fob, and either locks or opens the door. If the information doesn't match, the car will not be allowed to run.
When a car is connected with a specific fob, it will only receive signals from the device that is associated with it. Other fobs will not work with the car, even if they look similar. This protects the integrity of the car's computer system, and also to stop unauthorized key fobs from gaining control of the vehicle.
The majority of newer dealerships will only work with cars with original fobs, or genuine replacements offered by the manufacturer. It is because the only place with the expertise to prepare the replacement fob is the service department of a dealer. Certain aftermarket fobs, typically those for older models that have less sophisticated systems can be programmed with out the need for a dealer.
