Transponder Chips

If your car is made in the past 20 years, it is likely that it contains a transponder chip within of it. It's a small plastic thing inside the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.

When it is activated by an electro-magnetic field the chip emits a low-frequency signal. The signal is then amplified by the specific antenna that is fitted around the ignition barrel of your car. This allows the computer in your vehicle system to determine if the transponder chip in the key is the right one for your specific vehicle.

This prevents the vehicle from being started by hot-wiring or manipulating. The chip inside the key also verifies that you are the legal owner of the vehicle. This will help reduce car theft.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the computer in the car Key Reprogram detects the signal as valid, it will disable vehicle 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 designed to discourage people from attempting to alter the vehicle, but it is not a foolproof security measure.

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

Keyfobs can be programmed in a variety of ways depending on the make and model of your car. Certain models allow you to do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a new key fob or an additional one.

When you press the button on your key fob the microchip inside sends a code to the car's receiver it is linked to. The receiver compares the information with the 'allowed signals' stored in the key fob, and then opens or locks the car's doors. If the information does not match the signals, the car will not be allowed to drive.

Once the car is paired with a specific fob it will only receive signals from the device that is associated with it. This means that other fobs will not work with the vehicle, even though they appear similar. This is to safeguard the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle.

The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is because the only place that has the expertise to prepare the replacement fob is the service department of a dealer. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by consumers without the need for dealers.
