Transponder Chips If your car was built in the last 20 years, then it contains a transponder chip within of it. It's a small piece of plastic inside the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own. The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna attached to the ignition barrel. The computer system of the vehicle will then confirm that the key's transponder chip is the correct one for your car. This stops the vehicle from starting by hot-wiring or manipulating. The chip inside the key verifies 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 within the plastic part of the key, and there are different cuts that can be found on the keys: a cut laser cut (also called a sidewinder key) or Ford Tibbe key. 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 and cause it to send a signal back to the car. If the computer onboard the car recognizes the signal as valid it will turn off the car immobilizer so that the engine can start. If the vehicle does not recognize the transponder signal as the correct one, it will stop the engine from starting and will notify you by flashing its lights and sounding siren. This feature is designed to discourage people from trying to alter the vehicle, but it is not a foolproof security measure. A skilled and committed thief might be able get around this system using a special device to intercept the signal. As you can see there are quite number of benefits to having a transponder key. Every car owner should take this into consideration in order to safeguard their investment and decrease the chance of theft. Key Fobs Key fobs today can do more than just lock and unlock doors. They can also start the vehicle remotely, emit chirping sounds to aid in finding the car, or turn on the heated steering wheel. These extra features can make it difficult for you to find your car keys. Key fobs utilize radio frequencies to connect with one another and with the car. These frequencies are sent by a small antenna inside the middle of the key. The signal is encrypted to block other key fobs from stealing or modifying the signal. Keyfobs can be programmed in a variety of ways depending on the make and model of your vehicle. It is possible to do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or an additional fob. When you press the button on your key fob, the microchip inside transmits a code to the car's receiver it is paired with. The receiver compares the information with the 'allowed signals' that are stored in the key fob and then locks or opens the car's door. If the information doesn't match the fob's information, the car won't be allowed to run. Once the car has been connected to a specific fob, it can only receive signals from that device. In turn, other fobs won't work with the vehicle even though they have the same appearance. This protects the integrity of the computer system in the vehicle and stops unauthorised key fobs from taking control over it. Most newer car dealerships will only deal with cars with original fobs, or genuine replacements sold by the manufacturer. This is because the only place that has the knowledge to create a replacement fob is in a dealer's service department. However, some aftermarket fobs typically for older models that have less sophisticated systems can be programmed by consumers without the need for an authorized dealer.
