These tools aren't usually accessible to the general public and are only used by professionals. This kind of car key programming is referred to as EEPROM Programming and requires soldering, electronic expertise and a significant amount of time.
Other forms of programming car keys are a lot simpler and can be accomplished by anyone who is able to.

Key Programmers

Modern vehicles typically require a key programming procedure to initialize the vehicle's system and allow the vehicle to begin.

This is because the new key hasn't been programmed to the automobile's system. This can be quite costly. This is why it's a great idea to have two keys working for a modern car, so you can get the replacement key programmed if required.
A keyprogrammer can reprogram a transponder chip on the new mechanical key or key fob. It is also able to copy the data of an existing key to create duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). programming a key have diagnostic software that enables them to communicate with computers and also provide an interface that works bidirectionally with the immobilizer system.
There are many different types of keyprogrammers on the market. They are available in a variety of shapes, sizes and colors. Some are inexpensive, while others could cost thousands of dollars.

Transponder Chips
If your car was manufactured in the past 20 years, then it has a transponder chip inside of it. It's a small piece of plastic in the head of your key that contains an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is positioned around the barrel that controls your ignition in your car. This allows the car's computer system to confirm that the transponder chip that is in the key is the correct one for your specific vehicle.
This is what prevents hot-wiring or tampering with the ignition system of the vehicle to turn it on. The chip in the key also verifies that you are the legal owner of the vehicle. This helps to prevent car theft.
Transponder keys that are regular in shape like regular keys and have a plastic top. The chip itself is housed in the plastic portion of the key, and there are a few different types of cuts on the keys: a standard cut laser cut (also called a sidewinder), or a Ford Tibbe key.
The circuit in the induction coil will emit signals when the transponder is put into the ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer onboard the car is able to recognize the signal as correct it will turn off the vehicle immobilizer so that the engine can start.
If the car does not recognize the transponder signal as the right one, it will stop the engine from starting and will alert you by flashing its lights and sounding an alarm. This feature is intended to deter people from trying to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and determined criminal may still be able to escape this security system by employing a device designed to take over the signal.
You can see that a transponder is a great option. All car owners must take this into consideration in order to safeguard their investment and minimize the risk of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also turn on the car from a distance, make chirping sounds to help locate a car or switch on the heated steering wheel. Many of these extra features might seem useful however they could make it difficult for you to keep the track of your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies which are transmitted via an antenna that is located in the center of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.
There are several ways to program a key fob based on the vehicle's make and model. It is possible to do this yourself, however most modern vehicles require an expert locksmith or dealer to program a replacement or an additional fob.
When you press the button on a key fob, the microchip sends an indication to the receiver inside the vehicle with which it is linked. The receiver then compares the data with the permitted signals stored on the key fob and then locks or opens 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.
Once the car is linked with a specific fob, it will only receive signals from that device. This means that other fobs won't work with the vehicle even though they look the same. This protects the integrity of the car's computer system and prevent 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 offered by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security expertise that can only be found in the dealer service department. Some aftermarket fobs, usually ones for older models that have less sophisticated systems can be programmed with out the need for a dealer.
