Transponder Chips

If your car was manufactured in the past 20 years, then it contains a transponder chip within of it. This is the little plastic piece inside the head of your car key programmer that contains an RFID (Radio Frequency ID) chip with a code unique to your car.

The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to verify that the transponder chip inside the key is the right one for the car you have.

This prevents the vehicle from being started by hot-wiring or altering the key. The chip inside the car key verifies that the owner is the one who owns the vehicle. This can reduce car theft.

Transponder keys appear like regular metal keys but they have caps made of plastic. The chip is housed inside the plastic portion of the key, and there are different kinds of cuts available on these keys: a regular cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is received by the chip which then transmits a signal to the vehicle. If the computer onboard the car recognizes the signal as valid, it will disable vehicle immobilizer to allow the engine start.

If the car isn't able to recognize the transponder as the correct signal, it will not start the engine, and will warn you with flashing lights and a siren. This feature is intended to deter people from trying to hack into the vehicle, however it is not a foolproof security measure. A skilled and committed thief might be able get around this system employing a device designed to detect the signal.

Key Fobs

Key fobs today can be more than just a way to lock and unlock doors. They can also turn on the car remotely, make chirping noises to help locate the car or turn on the heated steering wheel. These additional features can make it difficult for you to find your car keys.

Key fobs make use of radio frequencies to communicate with one another and the car. The frequencies are transmitted by a small antenna inside the middle of the key. This communication is encrypted, which helps to keep others from stealing and replicating the signal.

You can program a keyfob in various ways based on the make and model of your car. Certain models allow you to do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer for them program a replacement key fob, or an alternative one.

When you press a key fob's button, the microchip inside transmits an informational code to the car's radio that it is paired with. The receiver compared this information to the signals that are allowed inside the fob, and either opens or locks the door. If the information isn't in line an chirping sound is heard and the car isn't able to function.

Once the car has been associated with a particular fob, it only accepts signals from the device. Other fobs won't work with the car, even though they look identical. This ensures the security of the computer system of the car and blocks unauthorized key fobs gaining control of it.

Most newer car dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge that is only available in the dealer service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by customers without the need of an authorized dealer.
