Transponder Chips If your car was built in the past 20 years, chances are it has a transponder inside of it. This is a little piece of plastic in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle. When it is activated by an electromagnetic 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 can then verify that the transponder chip of the key is the right one for your vehicle. This is what stops doing hot-wiring or altering the ignition system of the vehicle to turn it on. The chip in the car key verifies that the owner is the person who owns the vehicle. This will help reduce the possibility of theft from your vehicle. Transponder keys look like normal keys but they have caps made of plastic. The chip is contained within the plastic portion of these keys. There are a variety of cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe. A circuit inside the induction coil will emit a signal when the transponder is inserted into an ignition barrel. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the computer inside the car detects the signal as correct, it will disable vehicle immobilizer to allow the engine start. If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine and will alert you with flashing lights and siren. This function is designed to discourage those who would attempt to alter the vehicle. However it's not an absolute security measure. A skilled and determined thief could still be able to bypass this system by using a special device to detect the signal. As you can see there are quite few advantages to getting a transponder key. This is something that all car owners should consider if want 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 from a distance, make chirping sounds to help locate a car or turn on the heated steering wheel. These extra features can make it difficult to locate your car keys. Key fobs make use of radio frequencies to connect 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 stop others from stealing and re-transmitting the signal. There are many ways to program a key fob depending on the vehicle's model and make. Certain models allow you to do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a new key fob, or an alternative one. When you press the button on a key fob the microchip sends a signal to the receiver in the car with which it is linked. The receiver then compares the data with the 'allowed signals' stored in the key fob and then opens or locks 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 only accepts signals from the device. Other fobs won't work with the car, even though they look like. This is to safeguard the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle. Most dealerships with newer cars will only deal with cars that have original fobs, or genuine replacements offered by the manufacturer. The reason for this is that the only place that has the expertise to prepare the replacement fob is a dealer's service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems -- can be programmed by the consumer without the need of an authorized dealer.
