Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the last 20 years. It's the small piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your car.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then absorbed by a special antenna that is attached to the barrel of ignition. This allows the vehicle's computer system to confirm that the transponder chip in the key is the correct one for the car you have.
This stops the vehicle from starting by hot-wiring, or by tampering. The chip inside the key confirms that the owner is the one who is the owner of the vehicle. This helps to prevent car theft.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip is housed inside the plastic portion of the key, and there are a few different types of cuts on the keys: a cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.
The circuit in the induction coil will emit signals when the transponder is put into ignition barrel. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the computer inside the car is able to recognize the signal as being correct it will turn off the car immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will keep the engine from starting and will notify you by flashing its lights and sounding siren. This function is designed to discourage individuals from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and determined thief can still get around this system by using a specific device that intercepts the signal.
You can see that a transponder is a great option. This is something that all vehicle owners should consider if they want to protect their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making chirping sounds to help find the car in a parking space Key fobs today can also activate the heated steering wheel or open all windows with just a single click. These additional features can make it difficult to locate your car keys.
Key fobs communicate with one 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 intercepting or replicating the signal.
You can program a keyfob in various ways based on the model and brand of your car. You can sometimes do this yourself, but the majority of newer cars require that you visit a locksmith shop or a professional to program a replacement or an additional fob.
When you hit the button on a key fob, the microchip inside transmits a code to the car's receiver that it is paired with. The receiver then compares this information to the signals that are allowed inside the fob, and either opens or closes the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't allowed to function.
Once the car has been paired with a specific fob, it will only accept signals from that device. Other fobs won't work with the car, even though they appear like. This is to safeguard the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.
Most newer car dealerships will only deal with vehicles that have original fobs or genuine replacements supplied by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security knowledge that is only available in the dealer service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need for a dealership.
