Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the past 20 years. It's the tiny plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then taken up by the antenna that is fitted around the ignition barrel of your vehicle. This allows the vehicle's computer system to verify that the transponder chip inside the key is the correct one for the car you have.
This stops the vehicle from starting by hot-wiring or manipulating. The chip in the key also confirms that you are the legitimate owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys resemble normal keys but have caps made of plastic. The chip is contained within the plastic part of these keys. There are a variety of cuts that are a standard cut, Laser cut (also called 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 will then get taken up by the chip, causing it to transmit a signal back to the car. If the computer in the car recognizes the signal as correct, it will disable vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as the correct one, it will stop the engine from running and will alert you by flashing its lights and sounding an alarm. This is designed to discourage people from attempting to hack into the vehicle, however it is not a foolproof security measure. A skilled and determined thief could still evade this system by using a specific device that intercepts the signal.
You can see that a transponder is a great option. Every car owner should take this into consideration when they want to safeguard their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making chirping sounds to help find the car in a parking space, today's key fobs can also activate a heated steering wheel or roll down all windows with a single click. These extra features can make it difficult to find your car keys.
Key fobs communicate with each other and with the car through radio frequencies which are transmitted through a small antenna located in the middle of the key. The transmission is encrypted, which helps keep others from stealing and re-transmitting the signal.
You can program a keyfob in various ways based on the model and make of your vehicle. You can sometimes do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or additional fob.
When you hit the button on a key fob, the microchip inside transmits an informational code to the car's receiver that it is paired with. The receiver then compares the data with the permitted signals stored on the key fob and then it opens or closes the car's doors. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to operate.
When a car is connected with a particular fob, it will only receive signals from that device. This means that other fobs will not work with the vehicle even if they appear similar. This protects the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control of it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security skills that can only be found in the dealer's service department. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by consumers without the need for a dealership.
