Transponder Chips If your car was manufactured within the last 20 years, it is likely that it has a transponder inside of it. This is a little plastic piece in the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle. The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then absorbed by a special antenna attached to the ignition barrel. The computer system in the vehicle can then verify that the chip in the key's transponder is the correct one for your car. This stops the vehicle from starting by hot-wiring, or by manipulating. The chip in the key also proves that you are the legal owner of the vehicle. This can reduce car theft. Transponder keys look like normal keys, but with caps made of plastic. The chip is contained within the plastic portion of these keys. There are several different cuts that are a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe) and Ford Tibbe. When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will then get absorbed by the chip, causing it to transmit a signal back to the car. If the computer on the car recognizes this signal as the correct one, it will shut down the vehicle's immobilizer and allow the engine to begin. If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and will alert you with flashing lights and siren. This feature is designed to discourage people from attempting to hack into the vehicle, but it isn't a foolproof security measure. A skilled and determined thief might be able bypass this system by employing a device designed to detect the signal. As you can see, there are quite a number of benefits to having a transponder key. This is something that all vehicle owners should consider if they are looking to safeguard their investment and minimize the chance of theft. Key Fobs In addition to locking and unlocking doors, launching the car remotely or making chirping sounds to help find the car in a parking space Key fobs today can also turn on the heated steering wheel or roll down all of the windows with a single button press. Many of these extra features might seem useful, but they can also make it harder for you to keep the keys to your car. Key fobs communicate with one with the car via radio frequencies that are transmitted through an antenna in the center of the key. The communication is encrypted, which helps prevent others from intercepting and retransmitting the signal. You can program a keyfob in different ways based on the model and make of your vehicle. You can sometimes do this yourself, but the majority of newer automobiles require an expert locksmith or dealer to program a replacement or additional fob. When you press a key fob's button it transmits a code to the car's receiver it is linked to. The receiver then compares this information with the 'allowed' signals in the fob and then either locks or opens the door. If the data does not match, the car will not be allowed to operate. Once the car is paired with a specific fob, it can only receive signals from that device. As a result, other fobs will not work with the vehicle, even though they look the same. This protects the integrity of the computer system in the vehicle and stops unauthorized key fobs gaining control of it. Most dealerships with newer cars will only deal with vehicles that have original fobs, or genuine replacements supplied by the manufacturer. This is because the only place with the expertise to prepare a replacement fob is in the service department of a dealer. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by the consumer without the need of an authorized dealer.
