Transponder Chips If your car was manufactured within the past 20 years, it is likely that it has a transponder inside of it. It's a small plastic thing on the back of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own. The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then amplified by the specific antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system of the vehicle can then verify that the transponder chip of the key is the right one for your car. This prevents the vehicle from starting by hot-wiring, or by tampering. The chip inside the key confirms that the owner is the one who owns the vehicle. This can help to reduce the possibility of theft from your vehicle. Transponder keys appear like regular metal keys, but with a plastic cap. The chip is inside the plastic part of these keys. There are various cuts such as a standard cut laser cut (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe. The circuit in the induction coil will emit an electrical signal when the transponder is put into the ignition barrel. The signal will then get taken up by the chip and cause it to transmit a signal back to the car. If the computer inside the car is able to recognize the signal as being correct, it will disable vehicle immobilizer to allow the engine start. If the vehicle does not recognize the transponder signal as the correct one, it will stop the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage people from trying to alter the vehicle, however it is not a foolproof security measure. A skilled and determined thief could still bypass this system with a specially designed device that detects the signal. As you can see there are quite a few advantages to getting a transponder key. Every car owner should consider this in order to safeguard their investment and reduce the chance of theft. Key Fobs In addition to locking and unlocking doors, launching the car remotely or making sound chirps to help locate the car in a parking lot, today's key fobs can also activate the heated steering wheel or roll down all windows with just a single press. Many of these extra features may appear convenient, but they can also make it more difficult to keep track of your car keys. Key fobs utilize radio frequencies to communicate with one another and the car. These frequencies are sent by a small antenna within the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and re-transmitting the signal. There are many ways to program a key fob based on the make and model. Certain cars let you do this by yourself. However, most newer models require you to visit a professional locksmith or dealer to program a new key fob or an additional one. When you press the button on a key fob, the microchip sends signals to the receiver in the car with which it is paired. The receiver compared this information to the signals that are allowed on the fob and either opens or locks the door. If the information doesn't match the fob's information, the car won't be allowed to drive. Once the car is paired with a specific fob, it will only receive signals from that specific device. As a result, 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 car and prevents the use of unauthorized key fobs to gain control over it. The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security skills that is only available in the 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 for a dealership.
