Transponder Chips

If your car is made within the past 20 years, chances are it has a transponder key programming chip inside of it. It's the tiny plastic piece in the head of your car key that houses 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-level signal. This signal is then amplified by the specific antenna that is fitted around the ignition barrel of your vehicle. This allows the vehicle's computer system to verify that the transponder chip that is in the key is the correct one for your specific vehicle.

This stops the vehicle from being started through either hot-wiring or by altering the key. The chip in the key also confirms that you are the legal owner of the vehicle. This can help to reduce car theft.

Transponder keys look like regular keys made of metal, but with a plastic cap. The chip is housed inside the plastic portion of the key, and there are a few different kinds of cuts available on these keys: a cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.

The circuit in the induction coil will emit a signal when the transponder is inserted into the ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer inside the car is able to recognize the signal as correct it will turn off the vehicle 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 will alert you with flashing lights and an alarm.

Key fobs communicate with one other and the car using radio frequencies which are transmitted through an antenna that is located in the middle of the key. This communication is encrypted to stop others from stealing or stealing the signal.

There are many ways to program a key fob depending on your vehicle's make and model. You may be able to do it yourself, however most modern automobiles require a dealer or professional locksmith to program a replacement or an additional fob.

When you press the button on a key fob the microchip transmits signals to the receiver inside the vehicle with which it is linked. The receiver compared this information with the 'allowed' signals inside the fob, and either opens or locks the door. If the information does not match, the car will not be allowed to drive.

Once the car has been paired with a specific fob, it will only accept signals from that device. In turn, other fobs will not work with the vehicle even if they appear similar. This protects the integrity of the computer system of the vehicle and stops unauthorized key fobs gaining control of it.

Most dealerships with newer cars will only work with vehicles that have original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security knowledge that is only available in the dealer service department. Certain aftermarket fobs, typically those for older models that have less sophisticated systems can be programmed with out the need for a dealership.
