These tools are usually not available to the general public and are only used by professionals. This kind of programming is referred to as EEPROM Programming. It requires the ability to solder, electronic skills and a lot time.
Other types of car key programming are a lot simpler and can be accomplished by anyone who is able to.

Transponder Chips
Transponder chips are likely be found in vehicles manufactured within the past 20 years. It's a tiny plastic thing inside the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then absorbed by a special antenna attached to the barrel of ignition. This allows the car's computer system to confirm that the transponder chip that is in the key is the right one for your specific vehicle.
This is what stops hot-wiring or tampering with the vehicle's ignition system to start it. The chip inside the key also proves that you are the legal owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
programming car key are designed like regular keys and have an outer layer of plastic. The chip is located inside the plastic part of the keys. There are a variety of cuts that are a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
The circuit in the induction coil will emit an electrical signal when the transponder is placed in the an ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer inside the car detects the signal as being correct it will turn off the car immobilizer to allow the engine start.
If the car does not recognize the transponder signal as the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage individuals from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and determined thief can still get around this system with a specially designed device that intercepts the signal.
As you can see there are quite a number of benefits to having a transponder key. This is something that all car owners should consider if they want to protect their investment and reduce the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start your car from a distance, make chirping sounds to help locate cars, or turn on the heated steering wheel. A lot of these additional features might seem useful however they could make it more difficult to keep the track of your car keys.
Key fobs make use of radio frequencies to connect with one another and the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. This communication is encrypted to prevent others from stealing or stealing the signal.
There are a few different ways to program a key fob depending on the make and model. You may be able to do it yourself, but most newer cars require that you visit a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on a key fob the microchip sends an indication to the receiver in the vehicle with which it is paired. The receiver then compares the data with the 'allowed signals' that are stored in the key fob and then locks or opens the car's door. If the information does not match, the car will not be allowed to operate.
When a car is connected with a specific fob, it will only receive signals from the device that is associated with it. In turn, other fobs won't work with the vehicle even though they appear similar. This safeguards the integrity of the computer system that runs the car and prevents the use of unauthorized key fobs to gain control of it.
Most dealerships with newer cars will only work with cars that have original fobs, or genuine replacements supplied by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security expertise that can only be found in the dealer's service department. Some aftermarket fobs, usually ones for older models with less sophisticated systems, can be programmed without the need for a dealership.
