Transponder Chips

If your car was built in the past 20 years, then it has a transponder inside of it. It's a tiny plastic piece in the head of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.

The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna attached to the ignition barrel. The computer system of the vehicle can then verify that the chip in the key's transponder is the right one for your car.

This stops the vehicle from being started by hot-wiring, or by altering the key. The chip inside the key ensures that the owner is the person who owns the vehicle. This will help reduce the possibility of theft from your vehicle.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the car's computer detects this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to start.

If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine, and will notify you via flashing lights and an alarm.

When you press the button on a key fob, the microchip transmits a signal to the receiver inside the vehicle with which it is paired. The receiver compares the information with the 'allowed signals' stored in the key fob and then opens or locks the car door. If the information does not match the signals, the car will not be allowed to operate.

Once the car is linked with a particular fob, it will only receive signals from that specific device. In turn, other fobs won't work with the vehicle, even though they look the same. This ensures the security of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control of it.

Most dealerships with newer cars will only accept cars that have original fobs, or genuine replacements offered by the manufacturer.

Some aftermarket fobs, usually those from older models with less sophisticated systems, can be programmed without the need for a dealership.
