These tools aren't generally available to the public and are only used by professionals. This kind of programming for car keys is known as EEPROM Programming and requires soldering, electronic knowledge, and a lot of time.

This is because the new key has not been programmed into the vehicle's system. This can be quite costly. This is why it's a great idea to always have two keys that work for modern vehicles and have the replacement key programmed if required.
Keyprogrammers are devices that can recode the transponder chip on a new key fob or mechanical key. It can also clone the data of an existing key in order to create duplicates. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that enables them to communicate with the computer and also provide bidirectional interfaces to work with the 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
If your car was built in the past 20 years, it is likely that it contains a transponder chip within of it. It's a small plastic piece in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
When activated by an electro-magnetic field, the chip emits a low level signal. This signal then gets absorbed by the special antenna that is fitted around the barrel that controls your ignition in your vehicle. This allows the car's computer system to confirm that the transponder chip that is in the key is the correct one for the car you have.
This is what prevents doing hot-wiring or altering the vehicle's ignition system to get it started. The chip in the car key ensures that the owner is the one who owns the vehicle. This will help reduce the possibility of theft from your vehicle.
Regular transponder keys are designed like regular keys, but with a plastic top. The chip is contained within the plastic portion of the keys. There are a variety of cuts: a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer onboard the car detects the signal as being correct, it will disable vehicle immobilizer so that the engine can start.
If the car does not recognize the transponder signal as the right one, it will prevent the engine from starting and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage people from trying to tamper with the vehicle, however it's not a 100% security measure. A determined and skilled thief can still get around this system with a specially designed device that intercepts the signal.
As car keys programmed can see, there are quite a few advantages to getting a transponder key. All car owners must take this into consideration when they want to safeguard their investment and reduce the risk 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, today's key fobs can also switch on the heated steering wheel or roll down all of the windows with a single click. These extra features can make it difficult to locate your car keys.
Key fobs communicate with one other and with the car through radio frequencies which are transmitted through an antenna that is located in the middle of the key. The transmission is encrypted, which helps stop others from stealing and re-transmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the model and make of your vehicle. Certain models allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer for them program a replacement key fob or an additional one.
When you press the button on a key fob, the microchip transmits a signal to the receiver inside the car with which it is paired. The receiver then compares the data with the 'allowed signals' that are stored on the key fob and then it opens or closes the car's doors. If the information does not match the signals, the car will not be allowed to run.
Once the car is associated with a particular fob, it only accepts signals from the device. In turn, other fobs won't work with the vehicle even though they look the same. This helps to protect the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
Most newer car dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. It is because the only place with the expertise to prepare an appropriate replacement fob is the service department of a dealer. However, some aftermarket fobs -- usually those for older models with less sophisticated systems -- can be programmed by consumers without the need of dealers.
