Transponder Chips

Transponder chips can be found in vehicles manufactured in the last 20 years. It's a small plastic piece inside the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.

The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is attached to the barrel that controls your ignition in your car. This allows the vehicle's computer system to confirm that the transponder chip inside the key is the right one for your specific vehicle.

This stops the vehicle from being started through hot-wiring, or by manipulating. The chip in the car key verifies that the owner is the person who owns the vehicle. This can reduce car theft.

Transponder keys resemble regular metal keys but they have a plastic cap. The chip is located inside the plastic portion of these keys. There are several different cuts: a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.

The circuit in the induction coil emits a signal when the transponder is put into an ignition barrel. The signal will then get absorbed by the chip and cause it to transmit a signal to the car. If the computer inside the car detects the signal as being correct it will turn off the car immobilizer, allowing the engine to start.

If the car doesn't recognize the transponder as the correct signal, it won't start the engine and warn you with flashing lights and siren. This feature is designed to discourage people from attempting to hack into the vehicle, however it isn't a foolproof security measure. A skilled and determined criminal may still be able to get around this system using a device that can take over the signal.

It is evident that a transponder is a great option. Every car owner must take this into consideration if they wish to protect their investment and decrease the risk of theft.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely, or making sound chirps to help locate a car in a parking space keys of today can also switch on a heated steering wheel, or open all windows with a single press. These extra features can make it difficult for you to locate your car keys.

Key fobs use radio frequencies to connect with one another and the car. These frequencies are transmitted via a small antenna that is located in the middle of the reprogram key fob. The transmission is encrypted, which helps to prevent others from intercepting and re-transmitting the signal.

You can program a keyfob in various ways based on the make and model of your car. You can sometimes do this yourself, however most modern vehicles require a dealer or professional locksmith to program a replacement or a second fob.

When you press the button on a key fob the microchip transmits signals to the receiver in the vehicle with which it is paired. The receiver then compares the data with the 'allowed signals' that are stored on the key fob and then opens or locks the car door. If the data does not match the fob's information, the car won't be allowed to run.

After the car has been associated with a particular fob, it will only accept signals from that device. Other fobs will not work with the car, even though they appear similar. This is to safeguard the integrity of the vehicle's computer system and prevent unauthorised key fobs from taking control over the vehicle.

Most dealerships with newer cars will only accept cars 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 can only be found in the dealer's 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.
