These tools aren't usually available to the public and are used only by professionals. This type of programming is referred to as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot time.

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

Transponder Chips
If your car was manufactured in the past 20 years, then it has a transponder chip inside of it. It's the tiny plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is fitted around the ignition barrel of your vehicle. This allows the vehicle's computer system to confirm that the transponder chip that is in the key programmer near me is the correct one for the car you have.
This is the reason why hot-wiring or tampering with the ignition system of your vehicle to get it started. The chip inside the car key verifies that the owner is the one who owns the vehicle. This will help reduce the possibility of theft from your vehicle.
Transponder keys look like regular metal keys 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 regular standard cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.
A circuit inside the induction coil will emit signals when the transponder is placed in the an ignition barrel. The signal will then get received by the chip and cause it to send a signal back to the car. If the computer onboard the car key cut and programed is able to recognize the signal as being correct, it will disable vehicle immobilizer, allowing the engine to start.
If the car doesn't recognize the transponder as the correct signal, it will not start the engine and notify you via flashing lights and a siren. This is designed to deter people from trying to tamper with the vehicle, however it's not a 100% security measure. A skilled and skilled criminal could still bypass this system using a special device that detects the signal.

Key Fobs
Key fobs today do more than just lock and unlock doors. They can also turn on the vehicle remotely, emit chirping sounds to aid in finding the car or turn on the heated steering wheel. A lot of these additional features may appear convenient but they could make it more difficult to keep the track of your car keys.
Key fobs use radio frequencies to communicate with each other and the car key cut and programed. These frequencies are sent via a small antenna that is located inside the middle of the key. This communication is encrypted, which helps prevent others from intercepting and replicating the signal.
Keyfobs can be programmed in different ways based on the make and model of your car. It is possible to do this yourself, but the majority of newer automobiles require a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on a key fob the microchip transmits a signal to the receiver in the vehicle with which it is paired. The receiver compares 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 isn't in line the signals, a chirping sound can be heard and the car isn't able to operate.
When a car is connected with a specific fob it will only accept signals from that specific device. As a result, other fobs won't be able to work with the vehicle even if they look the same. This ensures the security of the computer system of the car and blocks unauthorised key fobs from taking control over it.
The majority of newer dealerships will only work with vehicles that have original fobs or genuine replacements offered by the manufacturer. It is because the only place with 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 that have less sophisticated systems -- can be programmed by consumers without the need of dealers.
