Transponder Chips

If your car is made in the last 20 years, it is likely that it contains a transponder chip within of it. This is the little piece of plastic 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 an unintentional radio signal when it is activated by an electromagnetic field. The signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system of the vehicle will then confirm that the transponder chip of the key is the right one for your vehicle.

This is the reason why hot-wiring or tampering with the ignition system of the vehicle to get it started. The chip inside the key also proves that you are the genuine owner of the vehicle. This will help reduce the possibility of theft from your vehicle.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will be absorbed by the chip, causing it to transmit a signal back to the car. If the computer in the car detects the signal as valid it will turn off the vehicle immobilizer, allowing the engine to start.

If the vehicle doesn't recognize the transponder signal as being the correct one, it will keep the engine from starting and will alert you by flashing its lights and sounding an alarm. This system is designed to deter those who would attempt to alter the vehicle. However it isn't an absolute security measure. A skilled and committed thief might be able get around this system employing a device designed to intercept the signal.

You can program a keyfob in a variety of ways depending on the model and make of your vehicle. You can sometimes do this yourself, but the majority of newer automobiles require a locksmith shop or a professional to program a replacement or an additional fob.

When you press the button on your key fob it transmits a code to the car's radio that it is linked to. car key programmer compares this information with the signals that are allowed on the fob and either locks or opens the door. If the data does not match the fob's information, the car won't be allowed to operate.

Once the car is paired with a particular fob, it will only receive signals from the device that is associated with it. In turn, other fobs will not work with the vehicle even if they have the same appearance. This ensures the security of the computer system in the vehicle and stops unauthorized key fobs gaining control over it.

The majority of newer dealerships will only accept vehicles that have original fobs, or genuine replacements sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge which can only be obtained in the dealer's service department. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems can be programmed by customers without the need for dealers.
