These tools are generally not accessible to the general public and are only used by professionals. This type of programming is known as EEPROM Programming. It requires the ability to solder, electronic skills and a lot time.
Other forms of programming car keys are much easier and can be accomplished by anyone who is able to.

It is recommended to have two keys that work for the modern automobile so that you can program the replacement key if needed.

A keyprogrammer can recode the transponder chip on the new mechanical key or key fob. It also can clone the data of an existing key to create duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). transponder key programmer are equipped with diagnostic software that allows them to communicate with the computer and also provide a bidirectional interface for working with the immobilizer system.

Transponder Chips
Transponder chips are likely be found in cars that were manufactured in the last 20 years. This is the little piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the car's computer system to verify that the transponder chip that is in the key is the right one for the car you have.
This stops the vehicle from being started through hot-wiring or manipulating. The chip in the key also proves that you are the legitimate owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip is inside the plastic part of the keys. There are several different cuts: a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal will be absorbed by the chip, causing it to transmit a signal back to the car. If the computer in the car detects the signal as valid it will turn off the vehicle immobilizer to allow the engine start.
If the car doesn't recognize the transponder as a valid signal, it will not start the engine and alert you with flashing lights and an alarm. This feature is designed to discourage people from trying to hack into the vehicle, but it isn't a foolproof security measure. A skilled and committed thief might be able get around this system employing a device designed to detect the signal.
As you can see, there are quite a number of advantages to having a transponder key. All car owners must take this into consideration in order to safeguard their investment and minimize the chance 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 lot keys of today can also switch on the heated steering wheel or roll down all of the windows with a single press. These additional features can make it difficult to locate your car keys.
Key fobs utilize radio frequencies to communicate with each other and the car. These frequencies are sent via a small antenna that is located inside the middle of the key. This communication is encrypted to block other key fobs from stealing or stealing the signal.
There are many ways to program a key fob based on the make and model. You may be able to do it yourself, but most 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 signals to the receiver inside the car that it is paired. The receiver compared the information with the 'allowed signals' that are stored on the key fob and then locks or opens the car's door. If the data does not match the signals, the car will not be allowed to run.
Once the car is paired with a specific fob it will only receive signals from that device. As a result, other fobs won't be able to work with the vehicle even if they have the same appearance. This safeguards the integrity of the computer system of the car and prevents the use of unauthorized key fobs to gain control over it.
Most newer car dealers will only work on cars with original fobs or genuine replacements offered by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security knowledge that is only available in the dealer service department. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by the consumer without the need for a dealership.
