These tools are not accessible to the general public and are used only by professionals. This type of car key programming is known as EEPROM Programming and requires soldering, electronic knowledge and a lot of time.

A keyprogrammer is a tool which can reprogram the transponder chip into the form of a new mechanical or key fob key. It can also clone the data from an existing key which allows duplicate keys to be made. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software, which allows them to communicate with a computer. They also feature a bidirectional user interface to work with an immobilizer system.

Transponder Chips

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

When it is activated by an electromagnetic field the chip emits a low level signal. This signal is then taken up by an antenna that is attached to the ignition barrel. The computer system of the vehicle is then able to verify that the key's transponder chip is the right one for your car.





This prevents the vehicle from being started by hot-wiring, or by manipulating. The chip in the key also confirms that you are the legal owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

Transponder keys look like regular metal keys, but with caps made of plastic. The chip is inside the plastic portion of the keys. There are various cuts that are a standard cut, laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal is received by the chip which sends a signal to the vehicle. If the computer on the car detects this signal as the correct one, it will shut down the vehicle immobilizer and allow the engine to begin.

If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and will warn you with flashing lights and an alarm. This system is designed to deter those who would attempt to alter the vehicle. However, it is not an unbreakable security measure. A skilled and determined thief could still bypass this system with a specially designed device that blocks the signal.

You can see that the transponder is an excellent option. This is something that all vehicle owners should consider if want to protect their investment and reduce the risk of theft.

Key Fobs

Key fobs today can do more than just 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 could make it difficult to locate your car keys.

Key fobs make use of radio frequencies to communicate with each other and with the car. These frequencies are transmitted by a small antenna within the middle of the key. The communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.

Keyfobs can be programmed in different ways based on the model and brand of your car. It is possible to do this yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or an additional fob.

When you press a key fob's button the microchip inside sends an informational code to the car's receiver it is paired with. The receiver then compares the data with the 'allowed signals' that are stored in the key fob, and then locks or opens the car door. If the information does not match the signals, the car will not be allowed to drive.

Once the car is connected to a specific fob, it will only accept signals from the device. Other fobs won't work with the car, despite the fact that they look identical. This protects the integrity of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control over it.

The majority of newer dealerships will only deal with vehicles that have original fobs or genuine replacements offered by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by customers without the need for dealers.
