Transponder Chips

If your car was manufactured within the last 20 years, chances are it has a transponder inside of it. It's a tiny plastic thing inside the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.

When activated by an electro-magnetic field the chip emits a low-level signal. The signal is then taken up by the antenna that is attached to the ignition barrel of your vehicle. This allows the vehicle's computer system to determine if the transponder chip in the key is the correct one for your specific vehicle.

This is the reason why from modifying or hot-wiring the vehicle's ignition system to turn it on. The chip inside the key ensures that the owner is the person who is the owner of the vehicle. This will help reduce car theft.

Transponder keys appear like normal keys but have caps made of plastic. The chip itself is housed in the plastic portion of the key and there are different kinds of cuts available on these keys: a regular cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.

The circuit in the induction coil will emit an electrical signal when the transponder is inserted into an ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as being the right one, it will turn off the vehicle's immobilizer and allow the engine to begin.

If the vehicle does not recognize the transponder signal as being the proper one, it will stop the engine from running and will alert you by flashing its lights and sounding siren. This is designed to deter people from trying to alter the vehicle, however it's not a 100% security measure. A skilled and committed thief could still be able to bypass this system by employing a device designed to detect the signal.

It is evident that the transponder is a good option. Every car owner should take this into consideration in order to safeguard their investment and minimize 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 keys of today can also switch on a heated steering wheel, or open all windows with just a single click. A lot of these features may appear convenient but they could make it more difficult to keep the track of your car keys.

Key fobs make use of radio frequencies to communicate with each other and with the car. The frequencies are transmitted through a small antenna located within the middle of the key. The signal is encrypted to prevent others from stealing or stealing the signal.

Keyfobs can be programmed in different ways based on the model and brand of your vehicle. You can sometimes do this yourself, but the majority of newer vehicles require a locksmith shop or a professional to program a replacement or an additional fob.

When you hit the button on a key fob it transmits a code to the car's receiver that it is paired with. The receiver compares this information to the 'allowed' signals inside the fob, and either locks or opens the door. If the data does not match the fob's information, the car won't be allowed to drive.

After the car has been associated with a particular fob, it will only accept signals from that device. As a result, other fobs won't be able to work with the vehicle even if they appear similar. This safeguards the integrity of the computer system of the car and blocks unauthorised key fobs from taking control of it.

Most dealerships with newer cars will only work with cars that have original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place that has the experience to design the replacement fob is the service department of the dealer. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by the consumer without the need of an authorized dealer.
