that were manufactured within the past 20 years Its a tiny plastic piece on the back of your key that contains a RFID Radio Frequency Identification chip with an individual code for your specific vehicle The chip emits an lowlevel radio signal once it is activated by an electromagnetic field The signal is then absorbed by the special antenna that is fitted around the barrel that controls your ignition in your vehicle This allows the cars computer system to confirm that the transponder chip inside the key is the right one for your particular car This stops the vehicle from being started by hotwiring or altering the key The chip inside the key also confirms that you are the genuine owner of the vehicle This helps to prevent the possibility of theft from your vehicle Transponder keys look like normal keys but with a plastic cap The chip is housed within the plastic part of the key and there are a few different kinds of cuts available on these keys a regular cut a laser cut also called a sidewinder key or a Ford Tibbe key A circuit inside the induction coil will emit a signal when the transponder is inserted into an ignition barrel The signal is received by the chip which sends a signal to the vehicle If the computer on the car detects this signal as the right one it will turn off the vehicles immobilizer and allow the engine to start If the car doesnt recognize the transponder as a valid signal it wont start the engine and will alert you with flashing lights and an alarm This feature is designed to discourage those who would attempt to alter the vehicle However it is not an unbreakable security measure A skilled and determined thief could still bypass this system with a specially designed device that intercepts the signal As you can see there are quite a number of advantages to having transponder keys All car owners should take this into consideration in order to safeguard their investment and reduce the chance of theft Key Fobs Key fobs today can be

features can make it difficult for you to locate your car keys Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted through an antenna in the middle of the key The signal is encrypted to block other key fobs from stealing or stealing the signal You can program a keyfob in a variety of ways depending on the model and make of your car You can sometimes do this yourself but the majority of newer vehicles require a dealer or professional locksmith to program a replacement or a second fob When you press the button on a key fob the microchip transmits an indication to the receiver inside the vehicle with which it is paired The receiver compares the information with the allowed signals that are stored on the key fob and then it opens or closes the car door If the data doesnt match a chirping sound is heard and the car isnt allowed to function Once the car is paired with a particular fob it will only receive signals from the device that is associated with it automotive key programming will not work with the car despite the fact that they look like This protects the integrity of the cars computer system and prevent unauthorised key fobs from taking control over the vehicle Most dealerships with newer cars will only work with vehicles that have original fobs or genuine replacements offered by the manufacturer It is because the only place with the expertise to prepare an appropriate replacement fob is the service department of the dealer Certain aftermarket fobs typically ones for older models that have less sophisticated systems can be programmed without the need for a dealership
