Transponder Chips

If your car was manufactured in the past 20 years, chances are it has a transponder inside of it. It's a small piece of plastic inside the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.

The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is positioned around the ignition barrel of your car. The computer system of the vehicle will then confirm that the key's transponder chip is the correct one for your car.

This prevents the vehicle from being started by hot-wiring, or by altering the key. The chip inside the key also confirms that you are the genuine owner of the vehicle. This will help reduce car theft.

A circuit within the induction coil will emit a signal when the transponder is placed in the the ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the computer inside the car recognizes the signal as valid it will turn off the vehicle immobilizer so that the engine can start.

If the vehicle doesn't recognize the transponder signal as being the right one, it will keep the engine from running and will alert you by flashing its lights and sounding siren. This feature is intended to discourage people from attempting to hack into the vehicle, but it isn't a foolproof security measure. A skilled and determined criminal may still be able to get around this system using a device that can detect the signal.

As you can see there are quite a number of benefits to having a transponder key. This is something that all vehicle owners should consider if want to protect their investment and decrease the chance of theft.

Key fobs are able to communicate with each other and with the car through radio frequencies which are transmitted by an antenna in the center of the key. This communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.

You can program a keyfob in different ways based on the model and make of your vehicle. You can sometimes do this yourself, but the majority of newer automobiles require a dealer or Car key reprogramming professional locksmith to program a replacement or an additional fob.

When you press a key fob's button the microchip inside sends a code to the car's radio that it is paired with. The receiver then compares this information to the signals that are allowed inside the fob, and either opens or locks the door. If the data does not match, the car will not be allowed to drive.

Once the car is paired with a specific fob, it can only receive signals from that device. Other fobs won't work with the car, despite the fact that they appear identical. This helps to protect the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.

Most dealerships with newer cars will only accept cars that have original fobs, or genuine replacements supplied by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security expertise that is only available in the dealer's service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems -- can be programmed by customers without the need for a dealership.
