These tools aren't generally accessible to the general public and are only used by professionals. This type of programming for car keys is known as EEPROM Programming and requires soldering, electronic expertise and a lot of time.
Other types of programming for car keys are much simpler and can be accomplished by the average person.

This is because the new key has not been programmed into the vehicle's system, and this could be quite expensive. This is why it's a great idea to always have two working keys for a modern automobile and to have the replacement key programmed if needed.
A keyprogrammer is a tool that recodes the transponder chip on an entirely new key fob or mechanical key. It is also able to copy information from an existing key in order to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that enables them to communicate with computers as well as bidirectional interfaces to work with the immobilizer system.
There are many different types of keyprogrammers available on the market. They come in all shapes, sizes and colors. Some are affordable while others are sophisticated and can cost thousands of dollars.

Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the past 20 years. It's a tiny plastic piece on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
When activated by an electro-magnetic field, the chip emits a low-level signal. This signal then gets taken up by the antenna that is attached to the barrel that controls your ignition in your car. This allows the vehicle's computer system to confirm that the transponder chip in the key is the correct one for your specific vehicle.
This is what prevents from modifying or hot-wiring the vehicle's ignition system to turn it on. The chip in the car key confirms that the owner is the one who owns the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys appear like regular metal keys but have caps made of plastic. The chip is located inside the plastic part of these keys. There are various cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe), and the Ford Tibbe.
The circuit in the induction coil will emit an electrical signal when the transponder is put into the ignition barrel. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the computer in the car detects the signal as correct it will turn off the vehicle immobilizer so that the engine can start.
If the car doesn't recognize the transponder as a valid signal, it won't start the engine and warn you with flashing lights and an alarm. This feature is designed to deter people from trying to tamper with the vehicle, but it's not a 100% security measure. A skilled and committed thief may still be able to escape this security system by using a device that can take over the signal.
As you can see there are quite a few advantages to getting a transponder key. Every car owner must take this into consideration if they wish to protect their investment and reduce theft risk.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also turn on the car remotely, emit chirping sounds to help locate a car or turn on the heated steering wheel. A lot of these features may seem convenient however they could make it difficult for you to keep track of your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted by an antenna that is located in the middle of the key. This communication is encrypted to prevent others from intercepting or replicating the signal.
There are many ways to program a key fob, based on the vehicle's model and make. car key programmer may be able to do it yourself, but the majority of newer cars require that you visit 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 an indication to the receiver inside the car that it is paired. The receiver compares this information to the signals that are allowed on the fob and either opens or closes the door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to function.
Once the car has been associated with a particular fob, it can only receive signals from that 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 that runs the vehicle and stops unauthorized key fobs gaining control over it.
Most newer car dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is because the only place with the expertise to prepare an appropriate replacement fob is the service department of the dealer. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems can be programmed by the consumer without the need of dealers.
