Transponder Chips

If your car was built within the last 20 years, chances are it has a transponder inside of it. It's a small piece of plastic inside the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.

When it is activated by an electromagnetic field, the chip emits a low-level signal. The signal is received by a specific antenna attached to the barrel of ignition. This allows the car's computer system to determine if the transponder chip inside the key is the right one for the car you have.

This stops the vehicle from being started by hot-wiring, or by altering the key. The chip inside the key also proves that you are the genuine owner of the vehicle. This can help to reduce car theft.

Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is housed in the plastic portion of the key and there are different kinds of cuts available on the keys: a standard cut, a 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 will send out the signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to begin.

If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and will notify you via flashing lights and siren. This function is designed to discourage those who would attempt to alter the vehicle. However it's not an unbreakable security measure. A skilled and committed thief could still be able to bypass this system by employing a device designed to take over the signal.

These additional features can make it difficult to locate your car keys.

Key fobs communicate with each other and with the car through radio frequencies which are transmitted via an antenna that is located in the middle of the key. The signal is encrypted to stop others from intercepting or replicating the signal.

You can program a keyfob in a variety of ways depending on the model and brand of your car. Certain models allow you to do it yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob, or an alternative one.

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

Once the car is linked with a specific fob, it will only receive signals from the device that is associated with it. This means that other fobs won't be able to work with the vehicle even though they appear similar. This protects the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.

Most newer car dealerships will only accept cars that have original fobs, or genuine replacements sold by the manufacturer. It is because the only place with the knowledge to create a replacement fob is in the service department of a dealer. Certain aftermarket fobs, typically those for older models that have less advanced systems can be programmed with out the need for a dealer.
