Transponder Chips Transponder chips can be found in cars manufactured within the last 20 years. It's a small plastic thing inside the head of your key that contains an RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle. The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is fitted around the barrel that controls your ignition in your car. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the correct one for your specific vehicle. This is what prevents hot-wiring or tampering with the vehicle's ignition system to get it started. The chip in the car key confirms that the owner is the one who is the owner of the vehicle. This can help to reduce the possibility of theft from your vehicle. Regular transponder keys are designed like regular keys and have a plastic top. The chip is located inside the plastic part of the keys. There are a variety of cuts that are a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe. The circuit in the induction coil emits signals when the transponder is inserted into an ignition barrel. The signal will then get taken up by the chip, causing it to transmit a signal to the car. If the car's computer recognizes this signal as the correct one, it will shut down the vehicle's immobilizer and allow the engine to start. If the car isn't able to recognize the transponder as the correct signal, it will not start the engine and will notify you via flashing lights and siren. This feature is designed to discourage individuals from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and determined criminal might be able escape this security system by employing a device designed to intercept the signal. It is evident that the transponder is an excellent option. Every car owner should take this into consideration when they want to safeguard their investment and reduce the risk of theft. Key Fobs Key fobs today offer more than locking and unlock doors. They can also turn on the vehicle remotely, emit chirping sounds to help locate the car, or switch on the heated steering wheel. A lot of these features might seem useful, but they can also make it harder for you to keep track of your car keys. Key fobs use radio frequencies to connect with one another and the car. The frequencies are transmitted through a small antenna located in the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and re-transmitting the signal. You can program a keyfob in a variety of ways depending on the make and model of your car. Some cars 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 additional one. When you press the button on your key fob it transmits an encoded code to the car's receiver 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 data does not match the fob's information, the car won't be allowed to operate. Once the car is paired with a specific fob, it will only accept signals from the device that is associated with it. Other fobs won't work with the car, even if they look similar. This protects the integrity of the computer system in the car and blocks unauthorised key fobs from taking control over it. Most newer car dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. It is because the only place with the experience to design an appropriate replacement fob is the service department of a dealer. Some aftermarket fobs, usually those for older models that have less advanced systems, can be programmed without the need for a dealership.
