These devices are handheld units 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
If your car is made in the last 20 years, then it contains a transponder chip within of it. It's a tiny piece of plastic inside the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then absorbed by a special antenna that is attached to the barrel of ignition. This allows the vehicle's computer system to verify that the transponder chip that is in the key is the correct one for your particular car.
This stops the vehicle from being started through hot-wiring, or by altering the key. The chip inside the key confirms that the owner is the person who is the owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
automotive key programming near me resemble regular keys made of metal but have caps made of plastic. The chip is housed in the plastic portion of the key and there are different types of cuts on these keys: a standard cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
A circuit inside the induction coil emits a signal when the transponder is placed in the ignition barrel. The signal will be received by the chip, causing it to send a signal back to the car. If the car's computer recognizes this signal as the correct one, it will shut down the vehicle immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and will warn you with flashing lights and siren. This feature is designed to discourage those who would attempt to alter the vehicle. However, it is not an unbreakable security measure. A skilled and determined criminal could still be able to bypass this system by using a device that can take over the signal.
It is evident that the transponder is a good option. Every car owner should consider this if they wish to protect their investment and reduce the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start the car from a distance, make chirping sounds to help locate a car, or turn on the heated steering wheel. These additional features could make it difficult to find your car keys.
Key fobs communicate with each other and with the car through radio frequencies which are transmitted via a small antenna located in the middle of the key. The communication is encrypted, which helps keep others from stealing and retransmitting the signal.
Keyfobs can be programmed in various ways based on the model and make of your car. You may be able to do it yourself, but the majority of newer vehicles require a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on your key fob it transmits an encoded code to the car's receiver it is linked to. The receiver compared the information with the permitted signals stored in the key fob and then it opens or closes the car's door. If the information doesn't match the signals, the car will not be allowed to run.
Once the car is paired with a particular fob, it will only receive signals from that specific device. Other fobs won't work with the car, despite the fact that they appear similar. This protects the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control of the vehicle.
Most newer car dealerships will only deal with cars that have original fobs or genuine replacements offered 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. However, some aftermarket fobs -- usually those for older models with less sophisticated systems -- can be programmed by customers without the need of an authorized dealer.
