These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with computers and also provide a bidirectional interface for working with the immobilizer system.

Transponder Chips
Transponder chips can be found in vehicles manufactured within the last 20 years. It's a tiny piece of plastic on the back of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
When it is activated by an electromagnetic field, the chip emits a low level signal. The signal is then amplified by the specific antenna that is fitted around the barrel that controls your ignition in your vehicle. The computer system in the vehicle is then able to verify that the transponder chip of the key is the correct one for your car.
This stops the vehicle from being started through either hot-wiring or by tampering. The chip inside the key also confirms that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are shaped like regular keys, but with a plastic top. The chip itself is housed within the plastic part of the key, and there are a few different kinds of cuts available on these keys: a cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
A circuit inside the induction coil emits signals when the transponder is inserted into the ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the onboard car computer recognizes this signal as the correct one, it will shut down the immobilizer on the vehicle 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 will warn you with flashing lights and a siren. This is designed to discourage people from attempting to hack into the vehicle, however it isn't a foolproof security measure. A determined and skilled thief can still get around this system with a specially designed device that detects the signal.
As you can see, there are quite a few advantages to getting transponder keys. Every car owner should consider this when they want to safeguard their investment and decrease the chance of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start the car from a distance, make chirping sounds to aid in finding a car or switch on the heated steering wheel. A lot of these features might seem useful however they could make it harder for you to keep the keys to your car.
Key fobs utilize radio frequencies to connect with one another and with the car. The frequencies are transmitted through a small antenna located inside the middle of the key. This communication is encrypted, which helps prevent others from intercepting and retransmitting the signal.
Keyfobs can be programmed in various ways based on the make and model of your vehicle. It is possible to do this yourself, but most newer cars require that you visit a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on a key fob, the microchip transmits signals to the receiver inside the vehicle with which it is linked. The receiver compares this information with the 'allowed' signals in the fob and then either opens or closes the door. If the information doesn't match, the car will not be allowed to drive.
Once the car is linked with a specific fob, it will only receive signals from that device. Other fobs won't work with the car, even though they look like. This helps to protect the integrity of the vehicle's computer system and prevent unauthorised key fobs from taking control over the vehicle.
Most newer car dealerships will only deal with vehicles that have original fobs, or genuine replacements sold by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security knowledge that can only be found in the dealer service department. Certain aftermarket fobs, typically those from older models with less sophisticated systems, can be programmed without the need for a dealership.
