These tools are not accessible to the general 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.

This is why it's a great idea to always have two keys working for a modern car, so you can get the replacement key programmed if needed.
A keyprogrammer can reprogram a 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 have diagnostic software that allows them to communicate with the computer and also provide an interface that works bidirectionally with the immobilizer system.
There are a variety of keyprogrammers on the market. They are available in a variety of sizes, shapes, and colors. Some are inexpensive and others are advanced and could cost thousands of dollars.

Transponder Chips
Transponder chips can be found in vehicles manufactured within the last 20 years. This is the little piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
When it is activated by an electromagnetic field the chip emits a low-level signal. This signal then gets amplified by the specific antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the car's computer system to determine if the transponder chip in the key is the right one for your particular car.
This stops the vehicle from starting by hot-wiring or manipulating. The chip in the car key ensures that the owner is the one who is the owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular keys and have an outer layer of plastic. The chip is housed in the plastic portion of the key and there are different kinds of cuts available on the keys: a standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
The circuit in the induction coil emits signals when the transponder is placed in the an ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the computer inside the car is able to recognize the signal as correct it will turn off the car immobilizer so that the engine can start.
If the car does not recognize the transponder signal as being the proper one, it will keep the engine from starting and will alert you by flashing its lights and sounding siren. This feature is designed to discourage those who would attempt to alter the vehicle. However, it is not a foolproof measure of security. A skilled and determined criminal may still be able to get around this system employing a device designed to intercept the signal.

As you can see, there are quite a number of benefits to having a transponder key. This is something that all car owners should consider if they are looking to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start the car remotely, make chirping noises to help locate the car or switch on the heated steering wheel. Many of these extra features may seem convenient but they could make it difficult for you to keep track of your car keys.
Key fobs utilize radio frequencies to communicate with each other and with the car. These frequencies are transmitted via a small antenna that is located inside the middle of the key. This communication is encrypted, which helps to stop others from stealing and re-transmitting the signal.
You can program a keyfob in various ways based on the model and make of your car. It is possible to do this yourself, but the majority of newer vehicles require a locksmith shop or a professional to program a replacement or additional fob.
When you press the button on a key fob the microchip sends signals to the receiver inside the car with which it is linked. The receiver then compares this information with the 'allowed' signals in the fob and then either locks or opens the door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate.
Once the car has been associated with a particular fob, it only accepts signals from the device. As a result, other fobs won't work with the vehicle, even though they appear similar. This safeguards the integrity of the computer system of the car and prevents unauthorized key fobs gaining control over it.
Most newer car dealerships will only deal with cars with original fobs, or genuine replacements offered by the manufacturer. It is because the only place that has the experience to design an appropriate replacement fob is the service department of the dealer. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need for a dealership.
