They are equipped with diagnostic software that enables them to communicate with the computer as well as a bidirectional interface for working with the immobilizer system.

Transponder Chips
If your car is made in the past 20 years, chances are it has a transponder chip inside of it. It's a tiny piece of plastic inside the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is attached to the barrel that controls your ignition in your vehicle. The computer system of the vehicle is then able to verify that the key's transponder chip is the right one for your car.
This stops the vehicle from being started by hot-wiring, or by manipulating. The chip in the key also verifies that you are the genuine owner of the vehicle. This will help reduce car theft.
Transponder keys resemble regular keys made of metal but they have caps made of plastic. The chip is contained within the plastic portion of these keys. There are a variety of cuts that are a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe), and Ford Tibbe.
The circuit in the induction coil emits a signal when the transponder is inserted into the ignition barrel. The signal will be taken up by the chip and cause it to transmit a signal back to the car. If the computer onboard the car recognizes the signal as being correct, it will disable 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 notify you via flashing lights and a siren. This is designed to discourage people from attempting to hack into the vehicle, however it is not a foolproof security measure. A skilled and determined thief could still be able to get around this system using a special device to take over the signal.

Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making sound chirps to help locate the car in a parking lot, today's key fobs can also switch on the heated steering wheel or open all windows with a single button press. These additional features can make it difficult for you to locate your car keys.
Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are sent through a small antenna located inside the middle of the key. The communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.
There are many ways to program a key fob depending on your vehicle's make and model. Some cars allow you to do it yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob, or an alternative one.
When you press the button on a key fob, the microchip transmits an indication to the receiver in the vehicle with which it is linked. The receiver compared this information to the 'allowed' signals stored inside the fob, and either locks or opens the door. If the information doesn't match the signals, the car will not be allowed to operate.
Once the car has been associated with a particular fob, it can only receive signals from that device. This means that other fobs will not work with the vehicle even though they have the same appearance. This protects the integrity of the computer system of the vehicle and stops unauthorized key fobs gaining control of it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security skills that is only available in the dealer service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by customers without the need of dealers.
