There are many types of car keys programming that can be accomplished by locksmiths who are professionals. Some are complex and require advanced tools. These tools are generally not accessible to the general public and are used only by professionals. This kind of programming is known as EEPROM Programming. It requires the ability to solder, electronic skills and a lot of time.

Key Programmers
Modern automobiles require a key-programming method to initialize their vehicle's systems and then start the vehicle. In some instances keys must be configured by the auto locksmith or dealer.

This can be quite costly. It's best to have two keys that are compatible for your modern car so you can program the replacement key whenever required.
A keyprogrammer can reprogram a transponder chip on the new mechanical key or key fob. It can also clone data from an existing key in order 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 computers. They also have a bidirectional user interface to work with an immobilizer system.
There are a myriad of types of keyprogrammers available on the market. They are available in a variety of sizes, shapes and colors.

Transponder Chips
Transponder chips can be found in cars that were manufactured within the past 20 years. It's the small plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your car.
When activated by an electro-magnetic field the chip emits a low-frequency signal. The signal is then absorbed by a special antenna attached to the barrel of ignition. The computer system in the vehicle is then able to verify that the transponder chip of the key is the right one for your car.
This prevents the vehicle from being started through hot-wiring, or by tampering. The chip inside the key ensures that the owner is the one who is the owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys resemble regular metal keys but they have caps made of plastic. The chip itself is housed in the plastic portion of the key and there are different types of cuts on these keys: a cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
A circuit within the induction coil will emit a 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 in the car detects the signal as correct, it will disable vehicle immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine and will notify you via flashing lights and siren. This feature is designed to discourage people from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and committed thief might be able escape this security system by using a special device to intercept 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 think about if they want to safeguard their investment and decrease 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 space Key fobs today can also activate a heated steering wheel or roll down all of the windows with a single button push. These extra features can make it difficult for you to locate your car keys.
Key fobs communicate with one other and the car using radio frequencies which are transmitted through an antenna in the center of the key. The communication is encrypted, which helps stop others from stealing and retransmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the make and model of your vehicle. You can sometimes do this yourself, however most modern vehicles require a locksmith shop or a professional to program a replacement or an additional fob.
When you press a key fob's button the microchip inside sends an informational code to the car's radio that it is linked to. The receiver then compares the data with the permitted signals stored in the key fob and then locks or opens the car door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate.
Once car key programming is paired with a specific fob, it will only accept signals from that specific device. Other fobs will not work with the car, even though they look identical. This helps to protect the integrity of the car's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security skills that is only available in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by customers without the need for dealers.
