Transponder Chips Transponder chips are likely be found in cars manufactured within the past 20 years. It's a tiny piece of plastic in the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle. When it is activated by an electro-magnetic field the chip emits a low level signal. The signal is received by a specific antenna that is attached to the barrel of ignition. The computer system in the vehicle is then able to verify that the chip in the key's transponder is the right one for your car. This is what prevents doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip inside the car key confirms that the owner is the one who owns the vehicle. This will help reduce car theft. Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip itself is housed in the plastic portion of the key and there are different kinds of cuts available on the keys: a standard cut laser cut (also called a sidewinder key) or Ford Tibbe key. When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out a signal. The signal will then get taken up by the chip, causing it to transmit a signal to the car. If the computer onboard the car detects the signal as being correct it will turn off the car immobilizer so that the engine can start. If the vehicle does not recognize the transponder signal as the proper one, it will stop the engine from starting and will notify you by flashing its lights and sounding a siren. This feature is intended to discourage people from trying to hack into the vehicle, but it's not a 100% security measure. A skilled and determined thief may still be able to bypass this system by employing a device designed to take over the signal. You can see that the transponder is an excellent option. This is something that all car owners should think about if 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 start the vehicle remotely, emit chirping sounds to aid in finding cars, or switch on the heated steering wheel. These extra features can make it difficult for you to locate your car keys. Key fobs use radio frequencies to communicate with one another and with the car. These frequencies are transmitted through a small antenna located within the middle of the key. This communication is encrypted, which helps prevent others from intercepting and retransmitting the signal. There are several ways to program a key fob, based on the model and make. You can sometimes do this yourself, but the majority of newer automobiles require an expert locksmith or dealer to program a replacement or a second fob. When you press a key fob's button the microchip inside sends a code to the car's receiver it is linked to. The receiver compared the information with the 'allowed signals' that are stored in the key fob and then opens or locks the car's doors. If the data doesn't match, a chirping sound is heard and the car isn't permitted to operate. Once the car is paired with a particular fob, it will only receive signals from that specific device. As a result, other fobs won't work with the vehicle even if they look the same. This helps to protect the integrity of the car's computer system and prevent unauthorized key fobs from gaining control of the vehicle. Most newer car dealerships will only deal with cars with original fobs or genuine replacements sold by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security knowledge that can only be found in the dealer's service department. Some aftermarket fobs, usually ones for older models that have less sophisticated systems can be programmed without the need for a dealer.
