Transponder Chips If your car was built within the last 20 years, chances are it has a transponder chip inside of it. It's a tiny piece of plastic in the head of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle. When activated by an electro-magnetic field, the chip emits a low level signal. This signal is then amplified by the specific antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system in the vehicle can then verify that the key's transponder chip is the correct one for your car. This prevents the vehicle from starting by hot-wiring, or by tampering. The chip inside the car key ensures that the owner is the person who is the owner of the vehicle. This will help reduce car theft. Transponder keys look like regular metal keys but they have caps made of plastic. The chip itself is housed in the plastic portion of the key, and there are a few different kinds of cuts available on the keys: a standard cut, a laser cut (also called a sidewinder), or a Ford Tibbe key. When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal will be taken up by the chip, causing it to transmit a signal back to the car. If the computer on the car recognizes this signal as being the right one, it will turn off the vehicle's immobilizer and allow the engine to begin. If the car doesn't recognize the transponder as the correct signal, it will not start the engine and notify you via flashing lights and a siren. This feature is intended to discourage people from attempting to hack into the vehicle, however it is not a foolproof security measure. A skilled and determined thief could still evade this system by using a specific device that detects the signal. As you can see there are quite number of advantages to having transponder keys. All car owners should consider this in order 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 turn on the car remotely, emit chirping sounds to aid in finding a car, or turn on the heated steering wheel. These extra features could make it difficult to find your car keys. Key fobs utilize radio frequencies to communicate with each other and with the car. These frequencies are sent through a small antenna located within the middle of the key. The communication is encrypted, which helps to stop others from stealing and re-transmitting the signal. There are a few different ways to program a key fob, based on the vehicle's make and model. You may be able to do it yourself, but the majority of newer cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob. When you hit the button on a key fob the microchip inside sends an informational code to the car's receiver it is linked to. The receiver then compares this information to the 'allowed' signals stored in the fob and then either opens or locks the door. If the data doesn't match, a chirping sound is heard and the car isn't able to operate. Once the car is paired with a specific fob, it only accepts signals from that device. Other fobs will not work with the car, even if they look like. This safeguards the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control of it. The majority of newer dealerships will only deal with cars that have original fobs, or genuine replacements offered by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security skills that is only available in the dealer service department. Certain aftermarket fobs, typically those from older models with less advanced systems can be programmed without the need for a dealership.
