Transponder Chips

If your car is made in the last 20 years, chances are it has a transponder inside of it. This is the little plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then taken up by the antenna that is fitted around the barrel that controls your ignition in your car. This allows the car’s computer system to determine if the transponder chip in the key is the right one for your particular car.

This prevents the vehicle from being started by hot-wiring, or by tampering. The chip in the car key ensures that the owner is the person who is the owner of the vehicle. This will help reduce car theft.

Transponder keys look like normal keys but they have a plastic cap. The chip is housed inside the plastic portion of the key, and there are different types of cuts on these keys: a regular standard cut laser cut (also called a sidewinder key), or a Ford Tibbe key.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer in the car detects the signal as being correct it will turn off the car immobilizer so that the engine can start.

If the vehicle doesn’t recognize the transponder signal as being the proper one, it will stop the engine from running and will notify you by flashing its lights and sounding siren. This feature is intended to deter people from trying to tamper with the vehicle, but it is not a foolproof security measure. A skilled and determined thief might be able get around this system employing a device designed to take over the signal.

You can see that the transponder is a good option. This is something that all vehicle owners should think about if they want to safeguard their investment and decrease 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 the car from a distance, make chirping sounds to aid in finding the car or turn on the heated steering wheel. Many of these extra features may seem convenient however they could make it harder for you to keep track of your car keys.

Key fobs make use of radio frequencies to connect with one another and with the car. The frequencies are transmitted by a small antenna within the middle of the key. This signal is encrypted to prevent others from intercepting or replicating the signal.

Keyfobs can be programmed in different ways based on the model and make of your car. You can sometimes do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or a second fob.

When you press the button on a key fob the microchip transmits an indication to the receiver inside the vehicle with which it is linked. The receiver compared the information with the permitted signals stored in the key fob, and then locks or opens the car’s door. If the data doesn’t match an chirping sound is heard and the car isn’t allowed to operate.

Once the car is paired with a particular fob, it will only accept signals from that specific device. Other fobs will not work with the car, even if they look similar. This protects the integrity of the car’s computer system and prevent unauthorised key fobs from taking control over the vehicle.

Most dealerships with newer cars will only accept cars with original fobs or genuine replacements offered by the manufacturer. This is because preparing a replacement fob requires technological and security skills that is only available in the dealer service department. Some fobs from the aftermarket, especially those for older models with less advanced systems, can be programmed without the need for a dealer.
