Transponder Chips

If your car was manufactured within the past 20 years, it is likely that it has a transponder inside of it. 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 the vehicle you own.

When it is activated by an electromagnetic field the chip emits a low level signal. This signal is then taken up by the antenna that is positioned around the ignition barrel of your car. This allows the car's computer system to determine if the transponder chip in the key is the correct one for your particular car.

This is what prevents doing hot-wiring or altering the ignition system of your vehicle to turn it on. The chip in the car key ensures that the owner is the one who owns the vehicle. This helps to reduce the risk of theft from your car.

Transponder keys resemble normal keys but they have a plastic cap. The chip is housed within the plastic part of the key and there are different kinds of cuts available on the keys: a cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.

A circuit inside the induction coil emits signals when the transponder is inserted into the ignition barrel. The signal will be taken up by the chip and cause it to transmit a signal to the car. If the computer inside the car detects the signal as correct it will turn off the car immobilizer, allowing the engine to start.

If the vehicle doesn't 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 siren. This feature is intended to discourage people from attempting to hack into the vehicle, however it is not a foolproof security measure. A skilled and determined thief might be able bypass this system by using a device that can detect the signal.

Key fobs utilize radio frequencies to communicate with one another and with the car. The frequencies are transmitted via a small antenna that is located inside the middle of the key. This communication is encrypted, which helps to stop others from stealing and retransmitting the signal.

Keyfobs can be programmed in different ways based on the make and model of your car. You can sometimes do this yourself, but the majority of newer cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob.

When you hit the button on a key fob it transmits an informational code to the car's radio that it is paired with. The receiver then compares the data with the permitted signals stored on the key fob and then locks or opens the car's door. If the data does not match the signals, the car will not be allowed to run.

After 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 if they appear like. This protects the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.

Most dealerships with newer cars will only accept cars that have original fobs or genuine replacements offered by the manufacturer. It is because the only place that has the experience to design a replacement fob is in the service department of the dealer. Some aftermarket fobs, usually ones for older models that have less advanced systems, can be programmed without the need for a dealership.
