Transponder Chips Transponder chips are likely be found in vehicles manufactured within the past 20 years. It's a tiny plastic piece on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own. The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is attached to the barrel that controls your ignition in your vehicle. 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 by altering the key. The chip in the car key confirms that the owner is the one who owns the vehicle. This helps to reduce the risk of theft from your car. Transponder keys appear 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 a few different kinds of cuts available on these keys: a cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key. When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will then get received by the chip and cause it to transmit a signal back to the car. If the onboard car computer detects this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to begin. If the vehicle doesn't recognize the transponder signal as being the proper one, it will keep the engine from starting and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage people from attempting to alter the vehicle, however it isn't a foolproof security measure. A skilled and committed thief may still be able to get around this system using a special device to take over the signal. As you can see there are quite a number of benefits to having transponder keys. This is something that all car owners should consider if they are looking 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 the car or switch on the heated steering wheel. Many of these extra features may seem convenient, but they can also make it more difficult to keep track of your car keys. Key fobs communicate with each other and with the car through radio frequencies which are transmitted by an antenna that is located in the middle of the key. The transmission is encrypted, which helps keep others from stealing and retransmitting the signal. There are several ways to program a key fob, based on your vehicle's make and model. Certain models allow you to do it yourself. However, the majority of newer models require you to visit an expert locksmith or dealer for them program a replacement key fob, or an alternative one. When you press the button on a key fob the microchip transmits signals to the receiver inside the vehicle with which it is linked. The receiver then compares this information to the 'allowed' signals stored in the fob and then either locks or opens the door. If the data does not match, the car will not be allowed to drive. Once the car is connected to a specific fob, it only accepts signals from that device. This means that other fobs won't work with the vehicle, even though they have the same appearance. This is to safeguard the integrity of the vehicle's computer system and prevent unauthorised key fobs from taking control of the vehicle. The majority of newer dealerships will only work with vehicles that have original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place that has the expertise to prepare an appropriate replacement fob is a dealer's service department. However, some fobs from the aftermarket — usually those for older models with less sophisticated systems — can be programmed by the consumer without the need of a dealership.
