These tools are not generally available to the public and are only used by professionals. This kind of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a lot time. Other types of key programming can be performed by anyone.

Transponder Chips If your car was manufactured in the last 20 years, then it has a transponder inside of it. It's the small plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own. When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then absorbed by a special antenna attached to the ignition barrel. The computer system in the vehicle is then able to verify that the transponder chip of the key is the correct one for your car.

The chip is housed in the plastic portion of the key, and there are a few different types of cuts on these keys: a regular standard cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key. When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer on the car recognizes this signal as the right one, it will shut down the immobilizer on the vehicle and allow the engine to begin. If the vehicle doesn't recognize the transponder signal as being the right one, it will keep the engine from starting and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage people from attempting to tamper with the vehicle, however it is not a foolproof security measure.

Key fobs use radio frequencies to connect with one another and with the car. The frequencies are transmitted via a small antenna that is located inside the middle of the key. The transmission is encrypted, which helps to keep others from stealing and replicating the signal. You can program a keyfob in various ways based on the model and brand of your car. programmed car keys is possible to do this yourself, however most modern vehicles require a locksmith shop or a professional to program a replacement or additional fob. When you press the button on a key fob, the microchip transmits an indication to the receiver in the car that it is paired. The receiver compared the information with the permitted signals stored in the key fob and then opens or locks the car's door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to function. Once the car is paired with a particular fob, it will only receive signals from that specific device. Other fobs will not work with the car, despite the fact that they look identical. This safeguards the integrity of the computer system of the car and blocks unauthorized key fobs gaining control over it. The majority of newer dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is because the process of creating a replacement fob requires technological and security knowledge which can only be obtained in the dealer's service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by customers without the need of an authorized dealer.
