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

Transponder Chips
If your car is made within the last 20 years, chances are it contains a transponder chip within of it. It's a tiny piece of plastic inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
When it is activated by an electromagnetic field the chip emits a low-level signal. The signal is then received by a specific antenna that is attached to the ignition barrel. The computer system of the vehicle can then verify that the transponder chip of the key is the right one for your car.
This is what prevents doing hot-wiring or altering the vehicle's ignition system to start it. The chip inside the key also confirms that you are the legal owner of the vehicle. This can reduce car theft.
Regular transponder keys are shaped like regular keys, but with an outer layer of plastic. The chip is inside the plastic part of the keys. There are various cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe), and Ford Tibbe.
A circuit within the induction coil emits signals when the transponder is inserted into ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the car's computer detects this signal as the correct one, it will disable the immobilizer on the vehicle and allow the engine to begin.
If the vehicle does not recognize the transponder signal as being the proper one, it will stop the engine from running and will alert you by flashing its lights and sounding a siren. This system is designed to deter individuals from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined thief can still get around this system by using a specific device that blocks the signal.
You can see that a transponder is a great option. This is something that all car owners should consider if they want to safeguard their investment and minimize the risk of theft.

In addition to locking and unlocking doors, starting the car remotely or making chirping sounds to help find a car in a parking space, today's key fobs can also activate a heated steering wheel, or roll down all windows with a single button click. These extra features could make it difficult to find your car keys.
Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are sent through a small antenna located in the middle of the key. The signal is encrypted to stop others from stealing or stealing the signal.
There are a few different ways to program a key fob, based on the model and make. Certain cars let you do this by yourself. However, most newer models require you to visit a professional locksmith or dealer to program a new key fob or additional one.
When you press the button on your key fob the microchip inside sends an informational code to the car's receiver that it is paired with. The receiver compares the information with the 'allowed signals' stored in the key fob, and then locks or opens the car door. If the information doesn't match the fob's information, the car won't be allowed to operate.
Once the car is associated with a particular fob, it can only receive signals from the device. Other fobs will not work with the car, even though they look like. This is to safeguard the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
Most newer car dealerships will only deal with cars with original fobs, or genuine replacements offered by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security knowledge that is only available in the dealer's service department. However, some aftermarket fobs typically for older models that have less sophisticated systems can be programmed by consumers without the need of an authorized dealer.
