These tools aren't generally available to the public and are utilized only by professionals. This type of programming is known as EEPROM Programming. It requires the ability to solder, electronic skills and a significant amount of time.
Other kinds of car key programming are much simpler and can be performed by the average person.

A keyprogrammer is a tool which can reprogram the transponder chip in a new key fob or mechanical key. It also can clone information from an existing key to create duplicates. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They come with diagnostic software, which allows them to communicate with a computer.

Transponder Chips
Transponder chips can be found in vehicles manufactured in the last 20 years. It's a tiny plastic piece in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip sends out an low-level radio signal once 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 verify that the transponder chip in the key is the right one for your particular car.
This is the reason why hot-wiring or tampering with the ignition system of your vehicle to start it. The chip inside the key verifies that the owner is the one who owns the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are shaped like regular keys and have a plastic top. The chip is housed within the plastic part of the key and there are a few different types of cuts on these keys: a regular cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
The circuit in the induction coil emits an electrical signal when the transponder is inserted into the ignition barrel. The signal will then get received by the chip and cause it to transmit a signal back to the car. If the computer inside the car is able to recognize the signal as correct it will turn off the vehicle immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine, and will alert you with flashing lights and an alarm. This function is designed to discourage those who would attempt to alter the vehicle. However, it is not an unbreakable security measure. A skilled and determined thief could still be able to escape this security system by using a special device to intercept the signal.
It is evident that a transponder is a great option. programming car keys is something that all vehicle owners should consider if want to safeguard their investment and reduce the chance of theft.
Key Fobs

A lot of these additional features might seem useful but they could make it more difficult to keep track of your car keys.
Key fobs make use of radio frequencies to connect with one another and the car. These frequencies are transmitted by a small antenna within the middle of the key. The communication is encrypted, which helps stop others from stealing and re-transmitting the signal.
There are many ways to program a key fob, based on the vehicle's model and make. You can sometimes do this yourself, but most newer automobiles require a locksmith shop or a professional to program a replacement or a second fob.
When you press the button on a key fob, the microchip transmits signals to the receiver inside the car with which it is linked. The receiver compared this information to the 'allowed' signals stored inside the fob, and either locks or opens the door. If the information doesn't match an chirping sound is heard and the car isn't allowed to operate.
Once the car is linked with a specific fob it will only accept 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 to prevent unauthorized key fobs from gaining control over the vehicle.
Most dealerships with newer cars will only work with cars that have original fobs or genuine replacements supplied by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security expertise which can only be obtained 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 an authorized dealer.
