Transponder Chips

Transponder chips are likely to be found in cars manufactured in the last 20 years. This is the little plastic piece inside the head of the car key programming and cutting key programmer that has an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.

When activated by an electro-magnetic field the chip emits a low-level signal. The signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system of the vehicle will then confirm that the transponder chip of the key is the right one for your car.

This prevents the vehicle from being started by hot-wiring, or by tampering. The chip in the car key verifies that the owner is the person who owns the vehicle. This helps to prevent car theft.

Transponder keys resemble regular metal keys, but with a plastic cap. The chip is contained within the plastic part of the key, and there are different types of cuts on these keys: a standard cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer on the car detects this signal as the right one, it will disable the vehicle immobilizer and allow the engine to begin.

If the vehicle doesn't recognize the transponder signal as being the right one, it will keep the engine from starting and will alert you by flashing its lights and sounding a siren. This feature is intended to discourage people from attempting to hack into the vehicle, but it is not a foolproof security measure. A skilled and determined thief could still be able to get around this system employing a device designed to take over the signal.

These extra features could make it difficult to locate your car keys.

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

You can program a keyfob in a variety of ways depending on the make and model of your vehicle. You may be able to do it yourself, however most modern cars require that you visit a locksmith shop or a professional to program a replacement or a second fob.

When you press the button on your key fob, the microchip inside transmits an informational code to the car's receiver it is paired with. The receiver compares the information with the 'allowed signals' stored on the key fob and then it opens or closes the car's doors. If the information doesn't match the signals, a chirping sound can be heard and the car isn't allowed to operate.

Once the car is paired with a specific fob, it will only accept signals from the device that is associated with it. This means that other fobs won't work with the vehicle, even though they look the same. This safeguards the integrity of the computer system in the car and prevents unauthorised key fobs from taking control over it.

The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements offered by the manufacturer. The reason for this is that the only place that has the knowledge to create a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket typically for older models with less sophisticated systems can be programmed by consumers without the need of an authorized dealer.
