Transponder Chips

Transponder chips are likely to be found in vehicles manufactured within the last 20 years. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your vehicle.

When activated by an electro-magnetic field the chip emits a low-frequency signal. This signal is then taken up by the antenna that is positioned around the barrel that controls your ignition in your car. This allows the car's computer system to confirm that the transponder chip that is in the key is the right one for the car you have.

This prevents the vehicle from starting by hot-wiring or altering the key. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This can reduce car theft.

Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip is located inside the plastic part of these keys. There are a variety of cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe.

A circuit inside the induction coil will emit signals when the transponder is placed in the an ignition barrel. The signal will then get absorbed by the chip, causing it to transmit a signal back to the car. If the computer onboard the car recognizes the signal as correct it will turn off the car immobilizer to allow the engine start.

If the vehicle doesn't recognize the transponder as being the proper signal, it won't start the engine, and will alert you with flashing lights and a siren. This system is designed to deter people from tampering with the vehicle. However, it is not an absolute security measure. A skilled and determined thief might be able get around this system using a device that can take over the signal.

When you press the button on a key fob, the microchip sends signals to the receiver in the car with which it is linked. The receiver compared the information with the 'allowed signals' stored on the key fob and then opens or locks the car door. If the data 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 accept signals from that specific device. As a result, other fobs won't work with the vehicle, even though they look the same. This ensures the security of the computer system of the car and prevents unauthorised key fobs from taking control over it.

The majority of newer dealerships will only work with cars with original fobs or genuine replacements sold by the manufacturer. car key cut and program is because preparing the replacement fob is a process that requires technological and security skills that is only available in the dealer service department.
