Transponder Chips
Transponder chips can be found in vehicles manufactured within the past 20 years. It's a tiny plastic piece on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is positioned around the barrel that controls your ignition in your car. The computer system of the vehicle is then able to verify that the key's transponder chip is the correct one for your car.
This is what prevents hot-wiring or tampering with the vehicle's ignition system to start it. The chip in the key also proves that you are the genuine owner of the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular keys and have an outer layer of plastic. The chip is inside 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 Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out a signal. The signal is received by the chip which then transmits a signal the vehicle. If the computer onboard the car recognizes the signal as valid it will turn off the car immobilizer to allow the engine start.
If the car does not recognize the transponder signal as the right one, it will stop the engine from starting and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage people from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined thief could still bypass this system by using a specific device that blocks the signal.
As you can see there are quite few advantages to getting transponder keys. This is something that all car owners should think about if they want to protect their investment and minimize the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start your vehicle from a distance, make chirping sounds to aid in finding cars, or switch on the heated steering wheel. These extra 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 in the middle of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.
There are a few different ways to program a key fob based on the model and make. Some cars allow you to do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer for them program a replacement key fob or an additional one.
When you press a key fob's button, the microchip inside transmits a code to the car's receiver that it is linked to. The receiver compares the information with the 'allowed signals' that are stored in the key fob and then opens or locks the car's doors. If the information doesn't match the signals, the car will not be allowed to run.
When a car is connected with a specific fob it will only receive signals from the device that is associated with it. In turn, other fobs will not work with the vehicle even though they appear similar. This helps to protect the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.
Most newer car dealerships will only work with cars with original fobs, or genuine replacements sold by the manufacturer. This is because preparing 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 that have less sophisticated systems -- can be programmed by consumers without the need for dealers.
