Transponder Chips

If your car was built in the past 20 years, chances are it has a transponder inside of it. This is the little plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to your car.

When it is activated by an electromagnetic field the chip emits a low-frequency signal. The signal is then absorbed by the special antenna that is fitted around the ignition barrel of your vehicle. The computer system of the vehicle will then confirm that the chip in the key's transponder is the correct one for your vehicle.

This prevents the vehicle from being started through either hot-wiring or by manipulating. The chip inside the key also confirms that you are the genuine owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.

Transponder keys look like regular metal keys, but with a plastic cap. The chip itself is housed in the plastic portion of the key and there are different cuts that can be found on these keys: a standard cut, a 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 inside of the induction coil sends out the signal. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the onboard car computer recognizes this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to start.

If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine and notify you via flashing lights and siren. This feature is designed to discourage people from trying to hack into the vehicle, but it is not a foolproof security measure. A skilled and determined criminal might be able escape this security system by using a special device to detect the signal.

It is evident that the transponder is an excellent option. This is something that all vehicle owners should think about if they want to safeguard their investment and minimize the risk of theft.

Key Fobs

Key fobs today can do more than just lock and unlock doors. They can also start your vehicle remotely, emit chirping sounds to help locate the car or turn on the heated steering wheel. A lot of these features may seem convenient but they could make it harder for you to keep track of your car keys.

Key fobs communicate with one with the car via radio frequencies that are transmitted by an antenna in the center of the key. The transmission is encrypted, which helps prevent others from intercepting and retransmitting the signal.

Keyfobs can be programmed in various ways based on the model and brand of your car. Some cars allow you to do it yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order for them program a replacement key fob or additional one.

When you press the button on a key fob, the microchip sends an indication to the receiver in the vehicle that it is paired. The receiver then compares this information with the 'allowed' signals stored inside the fob, and either locks or opens the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't permitted to function.

Once the car is associated with a particular fob, it will only accept signals from the device. Other fobs won't work with the car, even though they appear identical. This ensures the security of the computer system that runs the car and prevents unauthorized key fobs gaining control of it.

The majority of newer dealerships will only work with cars that have original fobs, or genuine replacements offered by the manufacturer. It is because the only place that has the experience to design a replacement fob is in a dealer's service department. Some aftermarket fobs, usually those for older models with less advanced systems can be programmed without the need for a dealer.
