These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with computers. They also have a bidirectional user interface that works with an immobilizer system.

Transponder Chips
If your car is made in the past 20 years, then it has a transponder 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 with a code unique to the vehicle you own.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna attached to the ignition barrel. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the right one for your specific vehicle.
This is what prevents from modifying or hot-wiring the vehicle's ignition system to get it started. The chip in the key also proves that you are the legal owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
Transponder keys resemble regular metal keys, but with caps made of plastic. The chip is housed within the plastic part of the key and there are different types of cuts on the keys: a standard cut laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will then get received by the chip, causing it to transmit a signal back to the car. If the computer in the car is able to recognize the signal as valid it will turn off the car immobilizer to allow the engine start.
If the car does not recognize the transponder signal as the right one, it will keep the engine from starting and will notify you by flashing its lights and sounding siren. This feature is designed to discourage people from tampering with the vehicle. However it isn't a foolproof measure of security. A skilled and determined thief may still be able to escape this security system by using a device that can take over the signal.
You can see that the transponder is an excellent option. Every car owner should consider this if they wish to protect their investment and decrease the chance of theft.

A lot of these additional features might seem useful however they could make it difficult for you to keep track of your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies that are transmitted through an antenna in the middle of the key. The transmission is encrypted, which helps to stop others from stealing and re-transmitting the signal.
reprogram car key can program a keyfob in various ways based on the model and brand of your car. automotive key programming 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 a key fob's button, the microchip inside transmits an informational code to the car's receiver it is linked to. The receiver compared the information with the 'allowed signals' stored on the key fob and then opens or locks the car's doors. If the information doesn't match an chirping sound is heard and the car isn't allowed to operate.
Once the car has been associated with a particular fob, it will only accept signals from that device. Other fobs will not work with the car, despite the fact that they appear identical. This is to safeguard the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements sold by the manufacturer. It is because the only place that has the knowledge to create the replacement fob is the service department of a dealer. Certain aftermarket fobs, typically ones for older models that have less advanced systems can be programmed without the need for a dealership.
