It’s the small piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your vehicle.When activated by an electro-magnetic field, the chip emits a low-level signal. This signal is then received by a specific antenna attached to the barrel of ignition. This allows the vehicle’s computer system to verify that the transponder chip that is in the key is the correct one for your specific vehicle.This prevents the vehicle from being started by hot-wiring, or by tampering. The chip inside the car key verifies that the owner is the one who owns the vehicle. This will help reduce car theft.Transponder keys look like regular metal keys but they have a plastic cap. The chip is housed within the plastic part of the key and there are a few different types of cuts on these keys: a standard cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.The circuit in the induction coil emits an electrical signal when the transponder is placed in the an ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the computer inside the car detects the signal as being correct it will turn off the car immobilizer to allow the engine start.If the vehicle does not recognize the transponder signal as the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding a siren. This function is designed to discourage individuals from tampering with the vehicle. However it isn’t a foolproof measure of security. A skilled and determined thief could still be able to escape this security system by using a special device to take over the signal.It is evident that the transponder is a good option. This is something that all vehicle owners should consider if they want to protect their investment and decrease the chance of theft.Key FobsIn addition to locking and unlocking doors, starting the car from a distance or making noises to aid in finding a car in a parking space keys of today can also activate a heated steering wheel or roll down all of the windows with a single click. These additional features can make it difficult to find your car keys.Key fobs communicate with one with the car via radio frequencies that are transmitted via an antenna that is located in the middle of the key. The transmission is encrypted, which helps to keep others from stealing and retransmitting the signal.There are many ways to program a key fob based on the vehicle’s make and model. reprogramming car keys 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 hit the button on a key fob it transmits an encoded code to the car’s receiver it is linked to. The receiver compared this information to the ‘allowed’ signals inside the fob, and either opens or locks the door. If the information doesn’t match the signals, a chirping sound can be heard and the car isn’t allowed to operate.Once the car is paired with a particular fob, it will only accept signals from that device. Other fobs will not work with the car, despite the fact that they look identical. This safeguards the integrity of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control over it.Most newer car dealerships will only deal with cars that have original fobs, or genuine replacements offered by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security expertise which can only be obtained in the dealer’s service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by consumers without the need for an authorized dealer.
