These tools are not available 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.

The reason for this is that the new key hasn't been programmed to the automobile's system. reprogram car key can be quite costly. This is why it's a great idea to have two keys that work for modern vehicles and have the replacement key programmed when required.
A keyprogrammer can recode the transponder chip on the new mechanical key or key fob. It can also clone data from an existing key to make duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that enables them to communicate with computers and also provide an interface that works bidirectionally with the immobilizer system.

Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. This is the little plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your car.
When it is activated by an electro-magnetic field the chip emits a low level signal. This signal is then absorbed by a special antenna that is attached to the barrel of ignition. The computer system of the vehicle is then able to verify that the transponder chip of the key is the right one for your car.
This stops the vehicle from starting by either hot-wiring or by tampering. The chip inside the key confirms that the owner is the person who is the owner of the vehicle. This helps to prevent car theft.
Transponder keys look like regular keys made of metal, but with caps made of plastic. The chip is housed inside the plastic portion of the key and there are different types of cuts on these keys: a regular standard cut laser cut (also called a sidewinder), or a Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the onboard car computer recognizes this signal as being the right one, it will turn off the vehicle's immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder as being the proper signal, it won't start the engine, and will warn you with flashing lights and a siren. This feature 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 by using a specific device that blocks the signal.
As you can see, there are quite a number of benefits to having transponder keys. Every car owner should consider this in order to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today 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 the car or switch on the heated steering wheel. These additional features can make it difficult to find your car keys.
Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are sent through a small antenna located inside the middle of the key. This communication is encrypted, which helps to keep others from stealing and replicating the signal.
You can program a keyfob in a variety of ways depending on the model and brand of your vehicle. You may be able to do it yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on your key fob, the microchip inside transmits an informational code to the car's radio that it is paired with. The receiver compared the information with the 'allowed signals' that are stored on the key fob and then opens or locks the car's doors. If the data doesn't match, a chirping sound is heard and the car isn't able to function.
Once the car is paired with a particular fob, it will only accept signals from that device. In turn, other fobs won't be able to work with the vehicle even though they have the same appearance. This is to safeguard the integrity of the car's computer system and prevent unauthorised key fobs from taking control over the vehicle.
Most dealerships with newer cars will only deal with cars that have original fobs, or genuine replacements sold by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise that is only available in the dealer's service department. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by consumers without the need of an authorized dealer.
