These tools are not available to the general public and are only used by professionals. This type of car key programming is referred to as EEPROM Programming and requires soldering, electronic expertise and a significant amount of time.

Key Programmers

The key might not function properly or it may not even start the vehicle in any way. The reason is because the new key has not been programmed into the vehicle's system. This can be quite expensive. This is why it's a great idea to have two keys working for a modern automobile and have the replacement key programmed when needed.
A keyprogrammer can recode the transponder chip on a new mechanical reprogramming key fob or key fob. It can also clone the data of an existing key and allow duplicate keys to be created. These are handheld devices that connect to the car key cutting and programming's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with the computer as well as bidirectional interfaces to work with the immobilizer system.
There are a number of different kinds of keyprogrammers on the market, and they come in a variety of shapes and sizes.

Some aren't reliable and could damage your vehicle.
Transponder Chips
Transponder chips can be found in cars that were manufactured within the last 20 years. It's a small plastic piece inside the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is then taken up by the antenna that is attached to the barrel that controls your ignition in your car. This allows the car's computer system to confirm that the transponder chip inside the key is the right one for your particular car.
This prevents the vehicle from starting by either hot-wiring or by tampering. The chip inside the key ensures that the owner is the person who owns the vehicle. This will help reduce car theft.
Transponder keys appear like normal keys but have caps made of plastic. The chip itself is housed in the plastic portion of the key and there are a few different cuts that can be found on the keys: a standard cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.
A circuit inside the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer onboard the car recognizes the signal as correct, it will disable vehicle immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as being the correct one, it will stop the engine from running and will notify you by flashing its lights and sounding an alarm. This feature is designed to deter people from trying to tamper with the vehicle, but it is not a foolproof security measure. A skilled and skilled criminal can still get around this system with a specially designed device that intercepts the signal.
It is evident that the transponder is a good option. This is something that all vehicle owners should consider if they want to protect their investment and minimize the chance of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start the car from a distance, make chirping sounds to aid in finding the car, or switch on the heated steering wheel. These additional features could make it difficult to locate your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies which are transmitted via an antenna that is located in the middle of the key. This signal is encrypted to stop others from stealing or stealing the signal.
Keyfobs can be programmed in various ways based on the make and model of your car. Some cars allow you to do this yourself. However, most newer models require you to visit an expert locksmith or dealer to program a replacement key fob, or an alternative one.
When you press the button on a key fob the microchip transmits a signal to the receiver inside the vehicle with which it is paired. The receiver then compares this information with the 'allowed' signals stored on the fob and either opens or locks the door. If the information doesn't match the fob's information, the car won't be allowed to drive.
Once the car key cut and program is paired with a specific fob it will only accept signals from that specific device. This means that other fobs won't work with the vehicle, even though they appear similar. This protects the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.
Most dealerships with newer cars will only work with cars that have original fobs, or genuine replacements sold by the manufacturer. It is because the only place with the expertise to prepare the replacement fob is the service department of the dealer. Certain aftermarket fobs, typically those from older models with less advanced systems can be programmed without the need for a dealer.
