These tools are generally not accessible to the general public and are used only by professionals. This type of key programming is called EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot time.

They have diagnostic software that enables them to communicate with the computer and also provide a bidirectional interface for working with the immobilizer system.

Transponder Chips

If your car was manufactured in the past 20 years, chances are it contains a transponder chip within of it. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your vehicle.

The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is fitted around the barrel that controls your ignition in your car. The computer system in the vehicle can then verify that the chip in the key's transponder is the correct one for your vehicle.

This is what prevents hot-wiring or tampering with the ignition system of the vehicle to get it started. The chip inside the key verifies that the owner is the one who is the owner of the vehicle. This helps to prevent car theft.

Transponder keys that are regular in shape like regular keys and have an outer layer of plastic. The chip is housed in the plastic portion of the key and there are different types of cuts on these keys: a standard cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.

The circuit in the induction coil emits an electrical signal when the transponder is placed in the ignition barrel. The signal will then get received by the chip, causing it to transmit a signal back to the car. If the car's computer detects this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to start.

If the vehicle doesn't recognize the transponder signal as the right one, it will stop the engine from running and will notify you by flashing its lights and sounding siren. This feature is intended to discourage people from trying to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and determined criminal could still be able to get around this system employing a device designed to intercept the signal.

It is evident that the transponder is a good option. This is something that all car owners should consider if they want to safeguard their investment and decrease the risk of theft.

Key Fobs

Key fobs today offer more than locking and unlock doors. They can also start your vehicle remotely, make chirping noises to help locate the car or turn on the heated steering wheel. Many of these extra features might seem useful but they could make it difficult for you to keep track of your car keys.

Key fobs utilize radio frequencies to connect with one another and the car. These frequencies are transmitted through a small antenna located in the middle of the key. This communication is encrypted to prevent others from intercepting or replicating the signal.

There are a few different ways to program a key fob depending on the make and model. Some cars allow you to do this by yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order for them program a replacement key fob, or an alternative one.

When you press the button on your key fob, the microchip inside transmits a code to the car's radio that it is linked to. The receiver compares the information with the 'allowed signals' stored in the key fob and then it opens or closes the car's door. If the information doesn't match the signals, the car will not be allowed to drive.

After the car has been associated with a particular fob, it only accepts signals from the device. Other fobs will not work with the car, even if they look like. This safeguards the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control of it.

Most dealerships with newer cars will only deal with cars with original fobs or genuine replacements supplied by the manufacturer. It is because the only place that has the knowledge to create the replacement fob is the service department of a dealer. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
