These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with the computer and also provide bidirectional interfaces to work with the immobilizer system.

Transponder Chips
If your car was built within the past 20 years, chances are it contains a transponder chip within of it. It's the tiny plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is attached to the ignition barrel of your car. This allows the computer in your vehicle system to confirm that the transponder chip in the key is the right one for your specific vehicle.
This is what stops hot-wiring or tampering with the ignition system of the vehicle to turn it on. The chip inside the car key ensures that the owner is the person who is the owner of the vehicle. This will help reduce car theft.
Transponder keys resemble normal keys but they have caps made of plastic. The chip is inside the plastic portion of the keys. There are a variety of cuts: a standard cut, a Laser cut (also known as a sidewinder or Ford Tibbe) and Ford Tibbe.
A circuit within the induction coil emits an electrical signal when the transponder is put into the ignition barrel. The signal will be taken up by the chip, causing it to transmit a signal back to the car. If the computer inside the car detects the signal as valid, it will disable vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as the correct one, it will stop the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to deter people from trying to alter the vehicle, however it's not a 100% security measure. A skilled and determined criminal might be able get around this system using a device that can take over the signal.

Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start your car from a distance, make chirping sounds to aid in finding the car, or turn on the heated steering wheel. A lot of these additional features might seem useful, but they can also make it harder for you to keep the keys to your car.
Key fobs communicate with each with the car via radio frequencies that are transmitted via a small antenna located in the middle of the key. This communication is encrypted, which helps to stop others from stealing and re-transmitting the signal.
Keyfobs can be programmed in various ways based on the make and model of your vehicle. You may be able to do it yourself, but the majority of newer vehicles require a locksmith shop or a professional to program a replacement or an additional fob.
When you hit the button on a key fob, the microchip inside transmits an informational code to the car's radio that it is linked to. The receiver then compares the data with the 'allowed signals' stored in the key fob, and then opens or locks the car door. If the information doesn't match an chirping sound is heard and the car isn't permitted to operate.
Once the car is paired with a particular fob, it will only accept signals from the device that is associated with it. In turn, other fobs won't work with the vehicle, even though they have the same appearance. This protects the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.
Most newer car dealerships will only accept vehicles that have original fobs, or genuine replacements sold by the manufacturer. This is because the only place with the experience to design a replacement fob is in a dealer's service department. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by customers without the need for dealers.
