This type of car key programming is known as EEPROM Programming and requires soldering, electronic knowledge and a lot of time.
Other kinds of car key programming are a lot simpler and can be performed by the average person.

Transponder Chips
If your car is made in the last 20 years, it is likely that it has a transponder chip inside of it. This is the little plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your car.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal is then taken up by the antenna that is positioned around the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to verify that the transponder chip that is in the key is the right one for the car you have.
auto key programmers prevents the vehicle from being started through either hot-wiring or by manipulating. The chip inside the car key confirms that the owner is the one who is the owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular metal keys with a plastic top. The chip is located inside the plastic part of the keys. There are a variety of cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
A circuit inside the induction coil will emit an electrical signal when the transponder is put into an ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as being the right one, it will shut down the immobilizer on the vehicle and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as 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 an absolute security measure. A skilled and determined thief might be able bypass this system by using a special device to detect the signal.
As you can see there are quite a number of advantages to having a transponder key. This is something that all vehicle owners should consider if they want to safeguard their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making chirping sounds to help find a car in a parking space keys of today can also switch on a heated steering wheel or open all windows with a single push. These extra features could make it difficult to locate your car keys.
Key fobs communicate with each other and the car using radio frequencies that are transmitted through an antenna that is located in the middle of the key. This signal is encrypted to prevent others from intercepting or replicating the signal.
There are several ways to program a key fob based on your vehicle's model and make. You can sometimes do this yourself, however most modern automobiles 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 a signal to the receiver inside the car with which it is linked. The receiver then compares the data with the 'allowed signals' that are stored in the key fob and then locks or opens the car's door. If the information doesn't match an chirping sound is heard and the car isn't allowed to operate.
Once the car is paired with a specific fob it will only accept signals from that specific device. As a result, other fobs won't be able to work with the vehicle even though they have the same appearance. This protects the integrity of the computer system of the car and blocks unauthorized key fobs gaining control over it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security expertise that can only be found in the dealer service department. Certain aftermarket fobs, typically those for older models with less advanced systems can be programmed with out the need for a dealership.
