These tools are usually not accessible to the general public and are only used by professionals. This kind of key programming is called EEPROM Programming.

This is why it's a good idea to always have two keys that work for a modern car, so you can get the replacement key programmed when necessary.
Keyprogrammers can recode the transponder chip on a new mechanical key or key fob. It is also able to copy the data of an existing key to make duplicates. 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. They also have a bidirectional interface for working with an immobilizer system.

Transponder Chips
If your car is made within the past 20 years, then it contains a transponder chip within of it. This is the little plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your car.
When activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then received by a specific antenna attached to the ignition barrel. The computer system in 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 ignition system of the vehicle to get it started. The chip in the key also confirms that you are the legitimate owner of the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip itself is housed inside the plastic portion of the key, and there are different cuts that can be found on these keys: a cut laser cut (also called a sidewinder), or a Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is received by the chip which then transmits a signal the vehicle. If the computer in the car detects the signal as valid it will turn off the vehicle immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder signal as the correct one, it will keep the engine from running and will alert you by flashing its lights and sounding an alarm. This function is designed to discourage individuals from tampering with the vehicle. However it isn't a foolproof measure of security. A skilled and determined criminal could still be able to get around this system using a special device to take over the signal.
As you can see there are quite number of benefits to having transponder keys. This is something that all car 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, launching the car remotely or making chirping sounds to help find a car in a parking lot, today's key fobs can also turn on the heated steering wheel or open all windows with a single button push. Many of these extra features may seem convenient but they could make it difficult for you to keep the keys to your car.
Key fobs communicate with one other and with the car through radio frequencies that are transmitted through an antenna that is located in the middle of the key. This communication is encrypted, which helps prevent others from intercepting and replicating the signal.
You can program a keyfob in different ways based on the model and make of your vehicle. You can sometimes do this yourself, but the majority of newer cars require that you visit an expert locksmith or dealer 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 in the car with which it is linked. The receiver then compares the data with the 'allowed signals' stored in the key fob, and then locks or opens the car's doors. If the information doesn't match, the car will not be allowed to run.
When a car is connected with a specific fob, it will only receive signals from that device. This means that other fobs won't be able to work with the vehicle even if they have the same appearance. This safeguards the integrity of the computer system of the car and blocks unauthorized key fobs gaining control of it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements offered by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security skills that is only available in the dealer service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need for dealers.
