Transponder Chips

Transponder chips can be found in cars that were manufactured within the last 20 years. It's the small plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your car.

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is fitted around the ignition barrel of your vehicle. This allows the car's computer system to verify that the transponder chip in the key is the right one for your specific vehicle.

This is the reason why doing hot-wiring or altering the ignition system of the vehicle to get it started. The chip in the key also proves that you are the genuine owner of the vehicle. This will help reduce car theft.

Regular transponder keys are shaped like regular metal keys with a plastic top. The chip itself is housed inside the plastic portion of the key and there are different types of cuts on these keys: a standard cut and program car Key, a laser cut (also called a sidewinder) or Ford Tibbe key.

A circuit within the induction coil emits an electrical signal when the transponder is inserted into the ignition barrel. The signal will then get received by the chip, causing it to transmit a signal back to the car. If the computer onboard the car is able to recognize the signal as being correct, it will disable vehicle immobilizer so that the engine can start.

If the car does not recognize the transponder signal as the correct one, it will stop the engine from running and will alert you by flashing its lights and sounding a siren. This function is designed to discourage those who would attempt to alter the vehicle. However it isn't a foolproof measure of security. A skilled and determined thief can still get around this system using a special device that intercepts the signal.

It is evident that the transponder is a good option. All car owners should take this into consideration when they want to safeguard their investment and reduce the chance of theft.

Key Fobs

These extra features can make it difficult to find your car keys.

Key fobs communicate with one other and the car using radio frequencies which are transmitted via an antenna that is located in the center of the key. The communication is encrypted, which helps to prevent others from intercepting and retransmitting the signal.

You can program a keyfob in various ways based on the make and model of your vehicle. It is possible to do this yourself, however most modern vehicles require a locksmith shop or a professional to program a replacement or additional fob.

When you press the button on a key fob the microchip sends a signal to the receiver in the car with which it is linked. The receiver compared this information to the 'allowed' signals stored on the fob and either opens or closes the door. If the information doesn't match, a chirping sound is heard and the car isn't able to operate.

Once the car has been connected to a specific fob, it will only accept signals from the device. Other fobs will not work with the car, despite the fact that they look similar. This protects the integrity of the computer system in 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. The reason for this is that the only place with the experience to design an appropriate replacement fob is a dealer's service department. Certain aftermarket fobs, typically those for older models with less advanced systems can be programmed without the need for a dealership.
