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

This is because the key has not yet been programmed into the car's system. This can be expensive. It is recommended to have two keys that are compatible for the modern automobile so that you can program the replacement key when needed.
A keyprogrammer can recode a transponder chip on a new mechanical key or key fob. It can also clone the information from an existing key and allow duplicate keys to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software, which allows them to communicate with a computer. They also feature a bidirectional user interface that works with an immobilizer system.
There are a number of various kinds of keyprogrammers on the market and they are available in all sizes and shapes.

Transponder Chips
Transponder chips can be found in cars manufactured within the past 20 years. This is the little plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal is then absorbed by the special antenna that is positioned around the barrel that controls your ignition in your car. This allows the computer in your vehicle system to confirm that the transponder chip in the key is the correct one for your particular car.
This is what stops from modifying or hot-wiring the ignition system of your vehicle to get it started. The chip in the key also verifies that you are the genuine owner of the vehicle. This can reduce car theft.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip itself is housed in the plastic portion of the key and there are different kinds of cuts available on these keys: a standard cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.
A circuit within the induction coil will emit an electrical signal when the transponder is put into an ignition barrel. The signal will be absorbed by the chip, causing it to transmit a signal to the car. If the car's computer recognizes this signal as the right one, it will turn off the vehicle's immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine and will alert you with flashing lights and an alarm. This function is designed to discourage people from tampering with the vehicle. However, it is not an absolute security measure. A skilled and skilled criminal could still evade this system using a special device that intercepts the signal.
You can see that the transponder is an excellent option. This is something that all car owners should think about if they want to protect their investment and reduce the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making sound chirps to help locate a car in a parking space keys of today can also activate the heated steering wheel or open all windows with a single push. Many of these extra features might seem useful but they could make it difficult for you to keep the track of your car keys.
Key fobs communicate with each with the car via radio frequencies which are transmitted through a small antenna located in the center of the key. The transmission is encrypted, which helps to stop others from stealing and retransmitting the signal.
There are many ways to program a key fob based on your vehicle's model and make. You can sometimes do this yourself, but the majority of newer automobiles 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 a code to the car's receiver it is paired with. The receiver then compares this information with the 'allowed' signals stored in the fob and then either locks or opens the door. If the information doesn't match, the car will not be allowed to operate.
Once the car is paired with a specific fob, it can only receive signals from that device. Other fobs will not work with the car, despite the fact that they look similar. This helps to protect the integrity of the vehicle's computer system, and also to stop unauthorized key fobs from gaining control of the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security skills that can only be found in the dealer service department. programming car key from the aftermarket, especially those from older models with less advanced systems can be programmed with out the need for a dealership.
