Transponder Chips Transponder chips can be found in cars that were manufactured in the last 20 years. It's a tiny piece of plastic in the head of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle. When it is activated by an electro-magnetic field, the chip emits a low level signal. This signal is then absorbed by a special antenna that is attached to the barrel of ignition. The computer system in the vehicle will then confirm that the chip in the key's transponder is the correct one for your vehicle. This stops the vehicle from being started through hot-wiring or altering the key. The chip in the key also proves that you are the legitimate owner of the 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 is taken up by the chip, which sends a signal to the vehicle. If the computer inside the car recognizes the signal as valid, it will disable vehicle immobilizer, allowing the engine to start. If the car does not recognize the transponder signal as being the proper one, it will prevent the engine from running and will notify you by flashing its lights and sounding a siren.

These additional features can make it difficult to locate your car keys. Key fobs utilize radio frequencies to connect with one another and the car. These frequencies are sent by a small antenna within the middle of the key. The signal is encrypted to block other key fobs from stealing or stealing the signal. There are many ways to program a key fob depending on the make and model. You may be able to do it yourself, but the majority of newer cars require that you visit a dealer or professional locksmith to program a replacement or additional fob. When you press a key fob's button it transmits an informational code to the car's receiver it is linked to. The receiver then compares this information to the 'allowed' signals on the fob and either opens or closes the door. If the information isn't in line an chirping sound is heard and the car isn't permitted to function. Once the car is paired with a specific fob, it will only accept signals from that device. This means that other fobs will not work with the vehicle even though they appear similar. This safeguards the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control of it. The majority of newer dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. The reason for this is that the only place with the experience to design a replacement fob is in the service department of the dealer. Some fobs from the aftermarket, especially those for older models that have less sophisticated systems can be programmed with out the need for a dealership.
