These tools aren't generally accessible to the general public and are only used by professionals. This kind of programming for car keys is referred to as EEPROM Programming and requires soldering, electronic expertise and a significant amount of time.
Other forms of car key programming are a lot simpler and can be performed by anyone who is able to. They are typically accomplished by using the onboard diagnostics port, that can be accessed using the key-fob-programming device.

A keyprogrammer can reprogram a transponder chip on the new mechanical key or key fob. It can also clone the data of an existing key in order to create duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that enables them to communicate with the computer as well as bidirectional interfaces to work with the immobilizer system.

Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the last 20 years. It's a tiny plastic thing on the back of your key that contains 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. The signal is then amplified by the specific antenna that is fitted around the ignition barrel of your car. The computer system in the vehicle can then verify that the transponder chip of the key is the right one for your car.
This is what stops from modifying or hot-wiring the ignition system of your vehicle to turn it on. The chip inside the car key confirms that the owner is the person who owns the vehicle. This can help to reduce the possibility of theft from your vehicle.
Transponder keys appear like regular keys made of metal but they have a plastic cap. The chip is housed within the plastic part of the key, and there are a few different cuts that can be found on these keys: a regular standard cut laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is received by the chip which then transmits a signal the vehicle. If the onboard car computer recognizes this signal as being the right one, it will disable the immobilizer on the vehicle and allow the engine to start.
If the car does not recognize the transponder signal as being the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This function is designed to discourage those who would attempt to alter the vehicle. However it isn't a foolproof measure of security. A skilled and determined thief could still evade this system with a specially designed device that intercepts the signal.
As you can see there are quite a number of advantages to having a transponder key. This is something that all car owners should consider if are looking to safeguard their investment and decrease the risk of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also turn on the vehicle remotely, emit chirping sounds to aid in finding cars, or turn on the heated steering wheel. These additional features can make it difficult for you to find your car keys.
Key fobs communicate with one with the car via radio frequencies that are transmitted through an antenna that is located in the center of the key. The signal is encrypted to block other key fobs from stealing or stealing the signal.
You can program a keyfob in different ways based on the model and brand of your car. Certain cars let you do this yourself. However, most newer models require you to visit a professional locksmith or dealer for them program a replacement key fob, or an alternative one.
When you hit the button on a key fob it transmits an informational code to the car's receiver it is paired with. The receiver compared the information with the 'allowed signals' that are stored in the key fob, and then it opens or closes the car door. If the information doesn't match the signals, the car will not be allowed to run.
After the car has been paired with a specific fob, it only accepts signals from that device. As a result, other fobs won't work with the vehicle even if they appear similar. This ensures the security of the computer system in the car and blocks the use of unauthorized key fobs to gain control over it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security skills that is only available in the dealer's service department. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by the consumer without the need for an authorized dealer.
