Transponder Chips

Transponder chips are likely to be found in cars manufactured in the last 20 years. It's the tiny plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to your car.

The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is then taken up by an antenna attached to the ignition barrel. This allows the vehicle's computer system to confirm that the transponder chip in the key is the right one for your specific vehicle.

This is the reason why from modifying or hot-wiring the vehicle's ignition system to start it. The chip inside the key programmer also verifies that you are the legal owner of the vehicle. This will help reduce car theft.

The circuit in the induction coil will emit an electrical signal when the transponder is inserted into an ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer inside the car is able to recognize the signal as being correct it will turn off the car immobilizer so that the engine can start.

If the car isn't able to recognize the transponder as the correct signal, it won't start the engine and alert you with flashing lights and an alarm. This feature is intended to discourage people from attempting to tamper with the vehicle, however it is not a foolproof security measure. A determined and skilled thief could still evade this system with a specially designed device that blocks the signal.

Many of these extra features might seem useful, but they can also make it more difficult to keep the track of your car keys.

Key fobs utilize radio frequencies to connect with one another and with the car. The frequencies are transmitted through a small antenna located within the middle of the key. The transmission is encrypted, which helps to prevent others from intercepting and re-transmitting the signal.

There are a few different ways to program a key fob based on the make and model. Certain models allow you to do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order to program a new key fob or an additional one.

When you press the button on your key fob the microchip inside sends an informational code to the car's receiver that it is paired with. The receiver compared the information with the permitted signals stored in the key fob and then opens or locks the car's doors. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to operate.

Once the car is paired with a specific fob, it will only accept signals from the device that is associated with it. As a result, other fobs won't be able to work with the vehicle even though they have the same appearance. This protects the integrity of the mobile car key programmer's computer system and prevent unauthorized key fobs from gaining control of the vehicle.

The majority of newer dealerships will only accept cars with original fobs, or genuine replacements supplied by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security knowledge that can only be found in the dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by consumers without the need of an authorized dealer.
