Transponder Chips

Transponder chips are likely to be found in cars that were manufactured within the last 20 years. This is the little plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is fitted around the ignition barrel of your vehicle. This allows the computer in your vehicle system to verify that the transponder chip inside the key is the correct one for your particular car.

This stops the vehicle from being started through hot-wiring, or by tampering. The chip inside the key also verifies that you are the legal owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.

Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip itself is housed within the plastic part of the key and there are a few different types of cuts on these keys: a cut laser cut (also known as a sidewinder key) or Ford Tibbe key.

The circuit in the induction coil will emit signals when the transponder is placed in the the ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the computer onboard the car is able to recognize the signal as being correct, it will disable vehicle immobilizer so that the engine can start.

If the vehicle does not recognize the transponder signal as being the correct one, it will prevent the engine from starting and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage people from tampering with the vehicle. However, it is not an absolute security measure. A skilled and determined thief could still be able to bypass this system by using a device that can take over the signal.

As you can see there are quite a number of benefits to having a transponder key. This is something that all car owners should think about if they are looking to safeguard their investment and minimize the risk of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely or making sound chirps to help locate a car in a parking lot, today's key fobs can also switch on a heated steering wheel, or open all windows with just a single press. A lot of these additional features may seem convenient however they could make it harder for you to keep the track of your car keys.

Key fobs use radio frequencies to connect with one another and the car. These frequencies are transmitted by a small antenna within the middle of the key. The transmission is encrypted, which helps prevent others from intercepting and retransmitting the signal.

You can program a keyfob in different ways based on the model and brand of your vehicle. It is possible to do this yourself, but most newer vehicles require an expert locksmith or dealer to program a replacement or an additional fob.

When you press the button on a key fob the microchip transmits signals to the receiver inside the car with which it is linked. The receiver compared the information with the 'allowed signals' that are stored in the key fob and then opens or locks the car door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to operate.

Once the car is linked with a specific fob, it will only accept signals from that specific device. Other fobs will not work with the car, even though they look identical. This helps to protect the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control of the vehicle.

Most newer car dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. This is because the process of creating a replacement fob requires technological and security expertise which can only be obtained in the dealer service department. Some fobs from the aftermarket, especially those from older models that have less sophisticated systems, can be programmed without the need for a dealer.
