Transponder Chips

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

The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is absorbed by a special antenna attached to the barrel of ignition. The computer system in the vehicle can then verify that the transponder chip of the key is the right one for your car.

This stops the vehicle from being started through hot-wiring or manipulating. The chip in 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 metal keys 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 regular cut laser cut (also known as 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 will send out a signal. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the car's computer detects this signal as the correct one, it will shut down the vehicle's immobilizer and allow the engine to begin.

If the car isn't able to recognize the transponder as being the proper signal, it will not start the engine, and will alert you with flashing lights and a siren. This system is designed to deter those who would attempt to alter the vehicle. However, it is not a foolproof measure of security. A skilled and determined thief may still be able to escape this security system by using a special device to detect the signal.

These additional features could make it difficult to find your car keys.

Key fobs communicate with each other and with the car through radio frequencies that are transmitted by an antenna in the center of the key. This communication is encrypted to prevent others from stealing or modifying the signal.

You can program a keyfob in a variety of ways depending on the make and model of your car. Certain models allow you to do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order for them program a replacement key fob or additional one.

When you hit the button on a key fob, the microchip inside transmits an encoded code to the car's radio that it is linked to. The receiver then compares the data with the 'allowed signals' that are stored in the key fob and then locks or opens the car door. If the information does not match the fob's information, the car won't be allowed to run.

Once the car is paired with a specific fob, it will only receive signals from the device that is associated with it. As a result, other fobs will not work with the vehicle, even though they have the same appearance. This helps to protect the integrity of the car's computer system and to prevent unauthorised key fobs from taking control of the vehicle.

Most newer programing car keys dealerships will only accept cars with original fobs, or genuine replacements sold by the manufacturer. This is because the only place with the knowledge to create a replacement fob is in a dealer's service department. Some aftermarket fobs, usually ones for older models that have less advanced systems can be programmed without the need for a dealership.
