RFID Radio Frequency ID chip with a code unique to the vehicle you own When activated by an electromagnetic field the chip emits a low level signal This signal then gets absorbed by the special antenna that is attached to the ignition barrel of your vehicle This allows the cars computer system to verify that the transponder chip in the key is the correct one for your particular car This prevents the vehicle from starting by hotwiring or manipulating The chip inside the key also confirms that you are the genuine owner of the vehicle This helps to prevent car theft Transponder keys resemble normal keys but have a plastic cap The chip is housed in the plastic portion of the key and there are different kinds of cuts available on these keys a standard cut laser cut also known as a sidewinder key or a Ford Tibbe key When the transponder key is inserted in the ignition barrel a circuit inside of the induction coil will send out the signal The signal will be received by the chip causing it to send a signal back to the car If the onboard car computer recognizes this signal as being the correct one it will turn off the vehicles immobilizer and allow the engine to start If the car doesnt recognize the transponder as being the proper signal it wont start the engine and notify you via flashing lights and a siren This function is designed to discourage those who would attempt to alter the vehicle However it isnt a foolproof measure of security A skilled and determined thief can still get around this system with a specially designed device that blocks the signal You can see that a transponder is a great option Every car owner should take this into consideration in order to safeguard their investment and decrease the risk of theft Key Fobs Key fobs today be more than just a way to lock and unlock doors They can also start your vehicle remotely emit chirping sounds to aid in finding cars or turn on the heated steering wheel A lot of these additional features may seem convenient but they can also make it harder for you to keep track of your car keys Key fobs communicate with one other and with the car through radio frequencies that are transmitted via a small antenna located in the middle of the key This communication is encrypted which helps to keep others from stealing and retransmitting the signal There are many ways to program a key fob based on your vehicles make and model It is possible to do this yourself but most newer vehicles require an expert locksmith or dealer to program a replacement or additional fob When you press a key fobs button the microchip inside transmits an informational code to the cars receiver it is linked to The receiver then compares the data with the permitted signals stored in the key fob and then it opens or closes the cars door If the information isnt in line the signals a chirping sound can be heard and the car isnt able to operate After the car has been paired with a specific fob it will only accept signals from that device This means that other fobs wont be able to work with the vehicle even if they look the same This protects the integrity of the vehicles computer system and prevent unauthorised key fobs from taking control of the vehicle The majority of newer dealerships will only work with cars with original fobs or genuine replacements sold by the manufacturer This is because the only place with the knowledge to create the replacement fob is a dealers service department Some fobs from the aftermarket especially those for older models with less sophisticated systems can be programmed without the need for a dealership
