Transponder Chips Transponder chips can be found in cars manufactured within the past 20 years. It's a small piece of plastic inside the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle. The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal is then received by a specific antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the correct one for your specific vehicle. This prevents the vehicle from being started by either hot-wiring or by altering the key. The chip in the car key confirms that the owner is the one who is the owner of the vehicle.

The chip itself is housed inside the plastic portion of the key and there are different kinds of cuts available on these keys: a cut laser cut (also known as a sidewinder key) or Ford Tibbe key. A circuit inside the induction coil emits signals when the transponder is placed in the an ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the computer onboard the car is able to recognize the signal as being correct it will turn off the car immobilizer, allowing the engine to start. If the car does not recognize the transponder signal as the right one, it will prevent the engine from starting and will notify you by flashing its lights and sounding a siren.

Many of these extra features might seem useful however they could make it more difficult to keep the track of your car keys.

You can sometimes do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or an additional fob.

The receiver then compares the data with the permitted signals stored on the key fob and then it opens or closes the car door. If the information doesn't match, a chirping sound is heard and the car isn't able to function. When a car is connected with a specific fob it will only receive signals from that device. Other fobs will not work with the car, despite the fact that they appear identical. This is to safeguard the integrity of the car's computer system and to prevent unauthorised key fobs from taking control over the vehicle. Most newer car dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer.
