These tools are generally not accessible to the general public and are only used by professionals. This type of key programming is called EEPROM Programming. It requires the ability to solder, electronic skills and a significant amount of time.
Other forms of programming car keys are much simpler and can be performed by anyone who is able to. These are usually done by using the diagnostics port on the car, that can be accessed using a special key-fob-programming tool.

A keyprogrammer is a tool that recodes the transponder chip into an entirely new key fob or mechanical key. It is also able to copy the data of an existing key in order to create duplicates. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with the computer, and they also have an interface that works bidirectionally with the immobilizer system.

Transponder Chips
If your car is made within the past 20 years, chances are it has a transponder chip inside of it. It's the small plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system in the vehicle is then able to verify that the transponder chip of the key is the right one for your vehicle.
This is what prevents doing hot-wiring or altering the ignition system of your vehicle to start it. The chip in the car key confirms that the owner is the person who is the owner of the vehicle. This will help reduce car theft.
Transponder keys appear like regular keys made of metal but have a plastic cap. The chip is housed inside the plastic portion of the key and there are different cuts that can be found on the keys: a cut laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out a signal. The signal will be received by the chip, causing it to transmit a signal to the car. If the car's computer recognizes this signal as being the right one, it will disable the vehicle immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as being the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This feature is designed to discourage people from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and skilled criminal can still get around this system by using a specific device that detects the signal.
As you can see there are quite a number of benefits to having a transponder key. All car owners must take this into consideration if they wish to protect their investment and reduce the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding the car in a parking lot Key fobs today can also activate a heated steering wheel, or open all windows with just a single click. These extra features can make it difficult to locate your car keys.
Key fobs utilize radio frequencies to communicate with one another and with the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. The transmission is encrypted, which helps prevent others from intercepting and re-transmitting the signal.
There are a few different ways to program a key fob depending on the vehicle's model and make. You may be able to do it yourself, however most modern cars require that you visit an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on a key fob the microchip sends an indication to the receiver in the vehicle with which it is linked. The receiver then compares the data with the 'allowed signals' that are stored in the key fob, and then opens or locks the car door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't permitted to operate.
When a car is connected with a specific fob, it will only accept 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 vehicle's computer system and prevent unauthorised key fobs from taking control over the vehicle.
Most dealerships with newer cars will only work with vehicles that have original fobs or genuine replacements sold by the manufacturer. This is because the only place that has the experience to design the replacement fob is a dealer's service department. Some fobs from the aftermarket, especially those from older models with less advanced systems can be programmed with out the need for a dealership.
