These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with a computer.

Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. It's a tiny piece of plastic in the head of your key that houses an RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is fitted around the ignition barrel of your car. The computer system of the vehicle can then verify that the transponder chip of the key is the right one for your vehicle.
This stops the vehicle from being started by either hot-wiring or by altering the key. The chip in the key also proves that you are the legal owner of the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip is located inside the plastic portion of the keys. There are various cuts that are a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe), and Ford Tibbe.
A circuit inside the induction coil will emit a signal 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 computer in the car detects the signal as being correct, it will disable vehicle immobilizer so that the engine can start.
If the car doesn't recognize the transponder as being the proper signal, it won't start the engine, and will alert you with flashing lights and a siren. This feature is designed to deter people from trying to alter the vehicle, but it's not a 100% security measure. A skilled and skilled criminal could still evade this system by using a specific device that intercepts the signal.
As you can see, there are quite a number of advantages to having transponder keys. Every car owner should consider this in order to safeguard their investment and reduce the risk of theft.
Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also start the car remotely, make chirping noises to help locate the car, or turn on the heated steering wheel. These extra features can make it difficult for you to locate your car keys.
Key fobs communicate with one other and the car using radio frequencies that are transmitted by an antenna in the middle of the key. This communication is encrypted to prevent others from stealing or modifying the signal.
There are a few different ways to program a key fob depending on the make and model. It is possible to do this yourself, but the majority of newer vehicles require a dealer or professional locksmith to program a replacement or additional fob.
When you press a key fob's button it transmits an informational code to the car's receiver that it is paired with. The receiver then compares the data with the 'allowed signals' stored on the key fob and then opens or locks the car's door. If the information doesn't match an chirping sound is heard and the car isn't able to function.
When a car is connected with a specific fob, it will only receive signals from the device that is associated with it. Other fobs won't work with the car, even though they look similar. This safeguards the integrity of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control over it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise which can only be obtained in the dealer service department. Some fobs from the aftermarket, especially those for older models with less advanced systems, can be programmed without the need for a dealer.
