They come with diagnostic software that enables them to communicate with computers and also provide a bidirectional interface for working with the immobilizer system.

Transponder Chips
If your car is made in the last 20 years, then it has a transponder chip inside of it. It's the small piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.
When activated by an electro-magnetic field the chip emits a low level signal. This signal then gets amplified by the specific antenna that is fitted around the ignition barrel of your car. The computer system in the vehicle can then verify that the key's transponder chip is the correct one for your car.
This is the reason why from modifying or hot-wiring the ignition system of your vehicle to start it. The chip in the car key confirms that the owner is the person who owns the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys resemble normal keys but have a plastic cap. The chip is located inside the plastic portion of the keys. There are several different cuts that are a standard cut, a Laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
The circuit in the induction coil will emit an electrical signal when the transponder is placed in the an ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer in the car is able to recognize the signal as being correct it will turn off the vehicle immobilizer to allow the engine start.
If the car doesn't recognize the transponder as the correct signal, it will not start the engine, and will notify you via flashing lights and a siren. This function is designed to discourage those who would attempt to alter the vehicle. However it's not an absolute security measure. A skilled and determined thief could still evade this system with a specially designed device that detects the signal.
You can see that the transponder is an excellent option. Every car owner should consider this in order to safeguard their investment and decrease theft risk.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making chirping sounds to help find a car in a parking lot, today's key fobs can also switch on the heated steering wheel or roll down all windows with a single push. A lot of these features may seem convenient however they could make it more difficult to keep the track of your car keys.
Key fobs communicate with one other and with the car through radio frequencies that are transmitted through an antenna in the center of the key. The communication is encrypted, which helps keep others from stealing and re-transmitting the signal.
You can program a keyfob in various ways based on the make and model of your vehicle. Certain cars let you do it yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a new key fob or an additional one.
When you press the button on a key fob the microchip sends a signal to the receiver inside the vehicle that it is paired. The receiver compares the information with the permitted signals stored in the key fob, and then locks or opens the car's door. If the information doesn't match an chirping sound is heard and the car isn't permitted to operate.
Once the car is associated with a particular fob, it can only receive signals from that device. In turn, other fobs won't be able to work with the vehicle, even though they look the same. This protects the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
Most dealerships with newer cars will only accept vehicles that have original fobs, or genuine replacements sold by the manufacturer. It is because the only place that has the experience to design the replacement fob is the service department of the dealer. Some aftermarket fobs, usually those for older models with less sophisticated systems can be programmed without the need for a dealer.
