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

Transponder Chips
If your car is made within the past 20 years, then it has a transponder inside of it. This is the little plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your car.
When activated by an electro-magnetic field the chip emits a low-level signal. The signal is then taken up by an antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the correct one for your particular car.
This is what stops from modifying or hot-wiring the ignition system of the vehicle to turn it on. The chip inside the key also confirms that you are the legal owner of the vehicle. This helps to prevent car theft.
Regular transponder keys are shaped like regular keys, but with a plastic top. The chip is contained inside the plastic portion of the key and there are different types of cuts on these keys: a regular cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal will then get absorbed by the chip and cause it to transmit a signal back to the car. If the computer inside the car detects the signal as correct, it will disable vehicle immobilizer so that the engine can start.
If the vehicle does not recognize the transponder signal as the proper one, it will keep the engine from starting and will notify you by flashing its lights and sounding a siren. This system is designed to deter people from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and committed thief may still be able to escape this security system by using a device that can take over the signal.
You can see that a transponder is a great option. This is something that all car owners should think about if they want to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today be more than just a way to lock and unlock doors. They can also start the car remotely, emit chirping sounds to help locate a car or switch on the heated steering wheel. Many of these extra features may seem convenient, but they can also make it more difficult to keep track of your car keys.
Key fobs make use of radio frequencies to connect with one another and with the car. These frequencies are transmitted by a small antenna inside the middle of the key. This communication is encrypted to stop others from stealing or stealing 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 most newer vehicles require an expert locksmith or dealer to program a replacement or an additional fob.
When you press the button on a key fob the microchip sends signals to the receiver inside the car with which it is paired. The receiver compares the information with the 'allowed signals' stored in the key fob, and then opens or locks the car's doors. If the information does not match the signals, the car will not be allowed to drive.
After the car has been connected to a specific fob, it will only accept signals from the device. As a result, other fobs won't work with the vehicle even though they look the same. This ensures the security of the computer system of the car and prevents unauthorized key fobs gaining control of it.
The majority of newer dealerships will only work with cars that have original fobs, or genuine replacements offered by the manufacturer. It is because the only place with the expertise to prepare a replacement fob is in the service department of a dealer. Certain aftermarket fobs, typically those for older models with less advanced systems can be programmed with out the need for a dealership.
