Transponder Chips Transponder chips are likely be found in cars manufactured within the last 20 years. It's a tiny plastic thing in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own. When it is activated by an electromagnetic field, the chip emits a low-level signal. This signal is then received by a specific antenna attached to the barrel of ignition. This allows the vehicle's computer system to confirm that the transponder chip inside the key is the correct one for your particular car. This stops the vehicle from starting by hot-wiring or altering the key. The chip inside the car key confirms that the owner is the one who owns the vehicle. This will help reduce car theft. Regular transponder keys are designed like regular keys and have a plastic top. The chip itself is housed in the plastic portion of the key and there are different types of cuts on these keys: a cut laser cut (also called a sidewinder), 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 taken up by the chip, which then transmits a signal to the vehicle. If the computer inside the car recognizes the signal as correct it will turn off the car immobilizer, allowing the engine to start. If the vehicle does not recognize the transponder signal as the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding a siren. This feature is intended to discourage people from trying to hack into the vehicle, however it is not a foolproof security measure. A skilled and determined criminal could still be able to escape this security system by employing a device designed to intercept the signal. As you can see, there are quite a number of benefits to having transponder keys. This is something that all vehicle owners should consider if they are looking to safeguard their investment and minimize the risk of theft. Key Fobs Key fobs today can be more than just a way to lock and unlock doors. They can also start your vehicle from a distance, make chirping sounds to help locate a car, or turn on the heated steering wheel. These additional features could make it difficult to locate your car keys. Key fobs utilize radio frequencies to communicate with each other and with the car. The frequencies are transmitted through a small antenna located within the middle of the key. This communication is encrypted, which helps to stop others from stealing and replicating the signal. There are a few different ways to program a key fob, based on the vehicle's make and model. Certain models allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer in order to program a new key fob or an additional one. When you hit the button on a key fob it transmits an informational code to the car's receiver that it is paired with. The receiver then compares the data with the 'allowed signals' stored on the key fob and then it opens or closes the car's door. If the information doesn't match the signals, the car will not be allowed to operate. Once the car is linked with a specific fob it will only accept signals from the device that is associated with it. As a result, other fobs won't be able to work with the vehicle even if they have the same appearance. This protects the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control of it. Most dealerships with newer cars will only accept cars that have original fobs or genuine replacements sold by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security skills that can only be found in the dealer service department. However, some fobs from the aftermarket typically for older models with less sophisticated systems can be programmed by the consumer without the need of dealers.
