Transponder Chips
If your car is made in the last 20 years, then it has a transponder inside of it. This is a little piece of plastic on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
When it is activated by an electro-magnetic field the chip emits a low level signal. This signal then gets absorbed by the special antenna that is fitted around the ignition barrel of your vehicle. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the right one for your specific vehicle.
This is what stops doing hot-wiring or altering the vehicle's ignition system to get it started. The chip inside the car key confirms that the owner is the one who owns the vehicle. This will help reduce car theft.
Transponder keys look like normal keys but have caps made of plastic. The chip is inside the plastic portion of these keys. There are a variety of cuts that are a standard cut, laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
A circuit inside the induction coil emits an electrical signal when the transponder is put into the ignition barrel. The signal will be received by the chip and cause it to transmit a signal to the car. If the car's computer recognizes this signal as the right one, it will turn off the vehicle's immobilizer and allow the engine to begin.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and notify you via flashing lights and siren. This is designed to discourage people from trying to tamper with the vehicle, however it is not a foolproof security measure.

There are many ways to program a key fob depending on your vehicle's model and make. It is possible to do this yourself, however most modern automobiles require an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on a key fob the microchip transmits signals to the receiver inside the vehicle with which it is paired. The receiver compares this information with the 'allowed' signals inside the fob, and either opens or closes the door. If the information doesn't match an chirping sound is heard and the car isn't permitted to function.
Once the car is linked with a specific fob, it will only accept signals from that specific device. Other fobs won't work with the car, even though they appear like. This protects the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
The majority of newer dealerships will only deal with vehicles that have original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place with the expertise to prepare the replacement fob is the service department of the dealer. However, some fobs from the aftermarket typically for older models that have less sophisticated systems -- can be programmed by the consumer without the need for dealers.
