Transponder Chips

If your car is made within the past 20 years, then it has a transponder inside of it. This is a little piece of plastic in the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.

When activated by an electro-magnetic field the chip emits a low-frequency signal. The signal is then taken up by the antenna that is attached to the barrel that controls your ignition in your car. The computer system in the vehicle will then confirm that the transponder chip of the key is the correct one for your vehicle.

This is what prevents hot-wiring or tampering with the vehicle's ignition system to turn it on. The chip inside the key also confirms that you are the genuine owner of the vehicle. This can reduce car theft.

Transponder keys that are regular in shape like regular keys and have an outer layer of plastic. The chip is contained within the plastic portion of the keys. There are various cuts: a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.

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 and cause it to transmit a signal to the car. If the computer in the car recognizes the signal as correct, it will disable vehicle immobilizer so that the engine can start.

If the car doesn't recognize the transponder as the correct signal, it will not start the engine, and will warn you with flashing lights and an alarm. This is designed to deter people from trying to hack into the vehicle, however it isn't a foolproof security measure.

Key fobs today can do more than just lock and unlock doors. They can also start your car from a distance, make chirping sounds to aid in finding the car, or switch on the heated steering wheel. These additional features could make it difficult to locate your car keys.

Key fobs make use of radio frequencies to connect with one another and with the car. The frequencies are transmitted through a small antenna located in the middle of the key. This communication is encrypted, which helps prevent others from intercepting and retransmitting the signal.

You can program a keyfob in different ways based on the model and make of your car. You can sometimes do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or an additional fob.

When you press the button on a key fob the microchip transmits signals to the receiver in the vehicle that it is paired. The receiver then compares the data with the permitted signals stored on the key fob and then opens or locks the car door. If the information doesn't match the signals, the car will not be allowed to run.

When a car is connected with a specific fob, it will only receive signals from that specific device. As a result, other fobs won't work with the vehicle even if they have the same appearance. This protects the integrity of the vehicle's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle.

Most newer car dealerships will only deal with vehicles that have original fobs or genuine replacements supplied by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security skills which can only be obtained in the dealer's service department. However, some fobs from the aftermarket typically for older models with less sophisticated systems can be programmed by consumers without the need of an authorized dealer.
