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

Transponder Chips
If your car is made within the past 20 years, chances are it has a transponder chip inside of it. It's the small piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your vehicle.
When it is activated by an electromagnetic field, the chip emits a low level signal. This signal is then absorbed by the special antenna that is positioned around the barrel that controls your ignition in your car. The computer system in the vehicle can then verify that the transponder chip of the key is the correct one for your vehicle.
This prevents the vehicle from starting by hot-wiring or tampering. The chip in the car key ensures that the owner is the one who is the owner of the vehicle. This will help reduce car theft.
Regular transponder keys are shaped like regular metal keys with a plastic top. The chip is contained within the plastic part of the key and there are different types of cuts on the keys: a cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer inside the car is able to recognize the signal as correct it will turn off the vehicle immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and alert you with flashing lights and siren. This is designed to discourage people from trying to alter the vehicle, however it is not a foolproof security measure. A skilled and determined thief could still be able to escape this security system by using a special device to intercept the signal.
As you can see there are quite a number of advantages to having transponder keys. All car owners should take this into consideration if they wish to protect their investment and minimize the risk of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start your vehicle from a distance, make chirping sounds to aid in finding a car, or turn on the heated steering wheel. A lot of these additional features may seem convenient but they could make it more difficult to keep track of your car keys.
Key fobs communicate with each other and the car using radio frequencies that are transmitted via a small antenna located in the middle of the key. The signal is encrypted to block other key fobs from stealing or stealing the signal.
There are click to program a key fob, based on the vehicle's model and make. It is possible to do this yourself, but most newer cars require that you visit an expert locksmith or dealer to program a replacement or a second fob.
When you hit the button on a key fob it transmits an informational code to the car's receiver that it is linked to. The receiver compares the information with the 'allowed signals' stored in the key fob and then locks or opens the car's door. If the information does not match the signals, the car will not be allowed to drive.
Once the car has been connected to a specific fob, it can only receive signals from that device. In turn, other fobs won't be able to work with the vehicle, even though they have the same appearance. This protects the integrity of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control over it.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security skills which can only be obtained in the dealer service department. Certain aftermarket fobs, typically those from older models with less sophisticated systems can be programmed with out the need for a dealer.
