Transponder Chips

If your car was built within the last 20 years, chances are it has a transponder chip inside of it. It's a tiny plastic thing inside the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for 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 taken up by the antenna that is fitted around the ignition barrel of your car. The computer system in the vehicle can then verify that the key's transponder chip is the correct one for your car.

This prevents the vehicle from starting by hot-wiring, or by tampering. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This will help reduce the possibility of theft from your vehicle.

Transponder keys look like regular keys made of metal, but with a plastic cap. The chip itself is housed within the plastic part of the key, and there are different kinds of cuts available on these keys: a standard cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.

A circuit within the induction coil will emit an electrical signal when the transponder is inserted into the ignition barrel. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the car's computer recognizes this signal as the right one, it will disable the immobilizer on the vehicle and allow the engine to begin.

If the vehicle doesn't recognize the transponder signal as being the proper one, it will keep the engine from starting and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage people from trying to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and determined criminal may still be able to bypass this system by employing a device designed to take over the signal.

A lot of these features may appear convenient however they could make it more difficult to keep track of your car key programming and cutting keys.

Key fobs communicate with each other and the car using radio frequencies that are transmitted through a small antenna located in the middle of the key. The transmission is encrypted, which helps prevent others from intercepting and replicating the signal.

There are several ways to program a key fob, based on the vehicle's make and model. You may be able to do it yourself, however most modern automobiles require a locksmith shop or a professional to program a replacement or an additional fob.

When you press the button on a key fob the microchip sends an indication to the receiver in the car with which it is linked. The receiver then compares the data with the permitted signals stored on the key fob and then locks or opens the car door. If the information does not match, the car will not be allowed to drive.

Once the car is paired with a specific fob it will only receive signals from that specific device. Other fobs will not work with the car, even though they look similar. This ensures the security of the computer system of the car and blocks unauthorised key fobs from taking control of it.

Most dealerships with newer cars will only deal with vehicles that have original fobs or genuine replacements offered by the manufacturer. The reason for this is that the only place that has the experience to design an appropriate replacement fob is a dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need of dealers.
