These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that enables them to communicate with the computer as well as an interface that works bidirectionally with the immobilizer system.

Transponder Chips
If your car is made within the past 20 years, chances are it has a transponder inside of it. It's a tiny piece of plastic on the back of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is absorbed by a special antenna that is attached to the ignition barrel. The computer system in the vehicle is then able to verify that the transponder chip of the key is the correct one for your vehicle.
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 proves that you are the legitimate owner of the vehicle. This will help reduce car theft.
Transponder keys appear like regular metal keys, but with a plastic cap. The chip is housed inside the plastic portion of the key and there are a few different types of cuts on these keys: a regular cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.
A circuit inside the induction coil emits a signal when the transponder is inserted into the ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the car's computer detects this signal as the right one, it will disable the vehicle immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine and will alert you with flashing lights and an alarm. This system is designed to deter those who would attempt to alter the vehicle. However it's not a foolproof measure of security. A skilled and skilled criminal could still bypass this system with a specially designed device that detects the signal.
As you can see there are quite a number of advantages to having transponder keys. This is something that all vehicle owners should consider if they want to protect their investment and reduce the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding the car in a parking lot, today's key fobs can also switch on a heated steering wheel, or roll down all windows with a single click. These additional features can make it difficult to find your car keys.
Key fobs make use of radio frequencies to communicate with one another and the car. These frequencies are transmitted via a small antenna that is located in the middle of the key. This communication is encrypted, which helps prevent others from intercepting and re-transmitting the signal.
There are several ways to program a key fob depending on the model and make. You can sometimes do this yourself, but most newer vehicles require 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 a signal to the receiver inside the car with which it is paired. The receiver compared the information with the 'allowed signals' that are stored in 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 permitted to operate.
Once the car is paired with a specific fob, it will only accept signals from that device. In turn, other fobs will not work with the vehicle even if they appear similar. This is to safeguard the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. The reason for this is that the only place that has the knowledge to create a replacement fob is in a dealer's service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems -- can be programmed by customers without the need of dealers.
