Transponder Chips If your car is made within the past 20 years, chances are it contains a transponder chip within of it. It's the small piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own. The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna attached to the barrel of ignition. The computer system of the vehicle will then confirm that the transponder chip of the key is the correct one for your vehicle. This stops the vehicle from being started by either hot-wiring or by altering the key. The chip in the key also confirms that you are the legitimate owner of the vehicle. This helps to prevent the possibility of theft from your vehicle. Regular transponder keys are shaped like regular metal keys with an outer layer of plastic. The chip itself is housed inside the plastic portion of the key, and there are a few different kinds of cuts available on these keys: a cut, a laser cut (also called a sidewinder) or Ford Tibbe key. A circuit inside the induction coil will emit an electrical signal when the transponder is placed in the an ignition barrel. The signal will then get received by the chip, causing it to transmit a signal to the car. If the car's computer recognizes this signal as being the correct one, it will shut down the vehicle immobilizer and allow the engine to begin. If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine, and will alert you with flashing lights and siren. This is designed to deter people from trying to alter the vehicle, however it isn't a foolproof security measure. A skilled and determined criminal could still be able to bypass this system by using a device that can detect the signal. As you can see, there are quite a number of advantages to having a transponder key. This is something that all car owners should think about if they are looking to safeguard their investment and decrease the chance of theft. Key Fobs Key fobs today do more than just lock and unlock doors. They can also start your vehicle remotely, make chirping noises to aid in finding the car, or switch on the heated steering wheel. Many of these extra features might seem useful but they could make it more difficult to keep the keys to your car. Key fobs communicate with one other and the car using radio frequencies which are transmitted by an antenna in the middle of the key. This communication is encrypted, which helps to keep others from stealing and re-transmitting the signal. Keyfobs can be programmed in different ways based on the model and make of your vehicle. Certain cars let you do this by yourself. However, most newer models require you to visit an expert locksmith or dealer for them program a replacement key fob or an additional one. When you press the button on your key fob, the microchip inside transmits an encoded code to the car's receiver that it is paired with. The receiver then compares the data with the 'allowed signals' that are stored in the key fob, and then it opens or closes the car door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't able to function. Once the car is connected to a specific fob, it will only accept signals from the device. Other fobs will not work with the car, even if they look like. This is to safeguard the integrity of the vehicle's computer system and to prevent unauthorised key fobs from taking control over the vehicle. The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. The reason for this is that the only place with the experience to design a replacement fob is in the service department of a dealer. Some fobs from the aftermarket, especially ones for older models with less sophisticated systems can be programmed without the need for a dealer.
