Transponder Chips

Transponder chips can be found in cars manufactured within the past 20 years. This is a little piece of plastic in the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.

When it is activated by an electromagnetic field, the chip emits a low-level signal. The signal is then received by a specific antenna that is attached to the barrel of ignition. The computer system in the vehicle can then verify that the chip in the key's transponder is the right one for your vehicle.

This stops the vehicle from being started through hot-wiring or manipulating. 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 appear like normal keys but they have a plastic cap. The chip is contained in the plastic portion of the key and there are different kinds of cuts available on these keys: a standard cut laser cut (also known as a sidewinder key) or Ford Tibbe key.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out the signal. The signal will then get taken up by the chip, causing it to transmit a signal back to the car. If the computer on the car detects this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to begin.

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 an alarm. This feature is intended to deter people from trying to hack into the vehicle, but it is not a foolproof security measure. A determined and skilled thief can still get around this system using a special device that detects the signal.

When you press a key fob's button it transmits a code to the car's receiver that it is linked to. The receiver then compares the data with the permitted signals stored in the key fob and then opens or locks the car's door. If the information isn't in line an chirping sound is heard and the car isn't allowed to function.

After the car has been paired with a specific fob, it will only accept signals from the device. This means that other fobs won't work with the vehicle even if they look the same. This protects the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control over the vehicle.

The majority of newer dealerships will only deal with cars that have original fobs, or genuine replacements supplied by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security expertise that can only be found in the dealer service department. Some aftermarket fobs, usually ones for car key reprogramming older models with less advanced systems can be programmed without the need for a dealer.
