Transponder Chips

If your car was built in the past 20 years, it is likely that it has a transponder inside of it. It's a small plastic piece 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 an low-level radio signal once it is activated by an electromagnetic field. This signal is then received by a specific antenna attached to the barrel of ignition. The computer system in the vehicle is then able to verify that the chip in the key's transponder is the right one for your car.

This is what stops from modifying or hot-wiring the ignition system of your vehicle to turn it on. The chip in the key also verifies that you are the legitimate owner of the vehicle. This will help reduce car theft.

Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip is contained inside the plastic portion of the key and there are a few different cuts that can be found on these keys: a cut laser cut (also called a sidewinder key), or a Ford Tibbe key.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer on the car key cut and program detects this signal as the right one, it will shut down the vehicle's immobilizer and allow the engine to start.

If the vehicle does not recognize the transponder signal as being the correct one, it will stop the engine from running and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage individuals from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and committed thief could still be able to escape this security system by employing a device designed to detect the signal.

Key Fobs

There are many ways to program a key fob depending on the vehicle's model and make. Some cars allow you to do this by yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob or additional one.

When you hit the button on a key fob the microchip inside sends an encoded code to the car's receiver it is paired with. The receiver compares this information with the signals that are allowed on the fob and either opens or closes the door. If the data does not match, the car will not be allowed to operate.

Once the car is paired with a specific fob it will only receive signals from that specific device. In turn, other fobs won't work with the vehicle, even though they appear similar. This ensures the security of the computer system that runs the car and blocks unauthorized key fobs gaining control of it.

The majority of newer dealers will only work on a car with original fobs or genuine replacements sold by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security knowledge that is only available in the dealer's service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems -- can be programmed by consumers without the need of dealers.
