These tools are not accessible to the general public and are used only by professionals. This type of programming is referred to as EEPROM Programming.

Transponder Chips

If your car was manufactured within the last 20 years, chances are it has a transponder inside of it. This is the little piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your vehicle.

When it is activated by an electro-magnetic field the chip emits a low level signal. This signal is then 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 in the key is the right one for your specific vehicle.

This is what stops from modifying or hot-wiring the vehicle's ignition system to get it started. The chip inside the car key ensures that the owner is the one who is the owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

A circuit inside the induction coil emits signals when the transponder is inserted into the ignition barrel. The signal will then get taken up by the chip, causing it to transmit a signal to the car. If the onboard car computer recognizes this signal as the right one, it will shut down the vehicle immobilizer and allow the engine to 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 siren. This feature is designed to discourage individuals from tampering with the vehicle. However it's not an unbreakable security measure.

The receiver compares the information with the 'allowed signals' stored in the key fob, and then locks or opens the car's doors. If the data doesn't match an chirping sound is heard and the car isn't allowed to function.

When a car is connected with a particular fob, it will only receive signals from that specific device. As a result, other fobs won't work with the vehicle, even though they appear similar. This protects the integrity of the computer system of 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 sold by the manufacturer.
