Transponder Chips

Transponder chips are likely be found in cars manufactured in the last 20 years. It's a tiny plastic thing on the back of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.

The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to verify that the transponder chip inside the key is the right one for the car you have.

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

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal will then get absorbed by the chip, causing it to transmit a signal back to the car. If the computer in the car recognizes the signal as valid, it will disable vehicle immobilizer, allowing the engine to start.

If the car doesn't recognize the transponder as a valid signal, it will not start the engine, and will notify you via flashing lights and a siren. This feature is designed to discourage people from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and committed thief could still be able to get around this system employing a device designed to detect the signal.

There are a few different ways to program a key fob based on the vehicle's model and make. Certain models allow you to do this by yourself. However, the majority of modern models require you to visit a professional locksmith or dealer for them program a replacement key fob, or an alternative one.

When you press the button on your key fob it transmits a code to the reprogram car keys's receiver that it is paired with. The receiver then compares the data with the 'allowed signals' that are stored in the key fob, and then opens or locks the car door. If the data does not match the signals, the car key reprogram will not be allowed to run.

After the car has been associated with a particular fob, it can only receive signals from that device. Other fobs won't work with the car, even though they appear similar. This protects the integrity of the computer system of the vehicle and stops unauthorized key fobs gaining control of it.

Most dealerships with newer cars will only deal with cars with original fobs or genuine replacements offered by the manufacturer. It is because the only place that has the experience to design the replacement fob is the service department of the dealer. However, some fobs from the aftermarket typically for older models that have less sophisticated systems -- can be programmed by customers without the need for a dealership.
