Transponder Chips

If your car was built in the last 20 years, it is likely that it has a transponder inside of it. This is the little piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your car.

When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then taken up by the antenna that is positioned around the ignition barrel of your vehicle. The computer system of the vehicle will then confirm that the key's transponder chip is the correct one for your car.

This stops the vehicle from starting by hot-wiring, or by tampering. The chip inside the key also confirms that you are the legal owner of the vehicle. This helps to reduce the risk of theft from your car.

The circuit in the induction coil will emit an electrical signal when the transponder is inserted into ignition barrel. The signal will be taken up by the chip, causing it to transmit a signal to the car. If the onboard car computer recognizes this signal as being the correct one, it will shut down the vehicle immobilizer and allow the engine to begin.

If the vehicle does not recognize the transponder signal as the correct one, it will prevent the engine from starting and will alert you by flashing its lights and sounding an alarm. This system is designed to deter individuals from tampering with the vehicle. However it isn't an absolute security measure. A skilled and determined criminal might be able bypass this system by using a special device to take over the signal.

As you can see there are quite number of advantages to having a transponder key. 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, today's key fobs can also switch on a heated steering wheel, or roll down all of the windows with a single button push. These additional features can make it difficult to locate your car keys.

Key fobs use radio frequencies to communicate with each other and with the car. The frequencies are transmitted by a small antenna within the middle of the key. The transmission is encrypted, which helps to stop others from stealing and retransmitting the signal.

There are many ways to program a key fob, based on the make and model. It is possible to do this yourself, but most newer cars require that you visit a locksmith shop or a professional to program a replacement or additional fob.

When you hit the button on a key fob it transmits a code to the car's receiver it is paired with. The receiver compares this information to the 'allowed' signals stored in the fob and then either opens or closes the door. If the data does not match the signals, the car will not be allowed to run.

Once the car is paired with a particular fob, it will only accept signals from that specific device. Other fobs won't work with the car, even if they appear like. This protects the integrity of the computer system in the car and prevents unauthorised key fobs from taking control of it.

Most newer car dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. This is because preparing a replacement fob requires technological and security skills which can only be obtained in the dealer service department. Certain aftermarket fobs, typically ones for older models that have less advanced systems can be programmed with out the need for a dealership.
