Transponder Chips

If your car was built in the last 20 years, it is likely that it has a transponder inside of it. It’s the small piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.

When it is activated by an electromagnetic field, the chip emits a low-frequency signal. The signal is then received by a specific antenna attached to the barrel of ignition. The computer system in 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 through either hot-wiring or by manipulating. The chip inside the car key ensures that the owner is the one who is the owner of the vehicle. This will help reduce car theft.

Regular transponder keys are designed like regular keys and have a plastic top. The chip is housed in the plastic portion of the key and there are a few different kinds of cuts available on the keys: a cut laser cut (also called a sidewinder key), or a Ford Tibbe key.

A circuit inside the induction coil emits an electrical signal when the transponder is put into an ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the onboard car computer recognizes this signal as being the right one, it will turn off the immobilizer on the vehicle and allow the engine to start.

If the vehicle doesn’t recognize the transponder signal as the proper one, it will prevent the engine from starting and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage people from attempting to hack into the vehicle, however it is not a foolproof security measure. A skilled and determined thief can still get around this system with a specially designed device that detects the signal.

A lot of these features may appear convenient, but they can also make it difficult for you to keep track of your car keys.

Key fobs communicate with one with the car via radio frequencies that are transmitted through a small antenna located in the center of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.

There are several ways to program a key fob depending on your vehicle’s model and make. Certain cars let you do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a replacement key fob, or an alternative one.

When you press a key fob’s button the microchip inside sends a code to the car’s receiver it is linked to. The receiver compares the information with the ‘allowed signals’ that are stored in the key fob and then locks or opens the car door. If the information doesn’t match the fob’s information, the car won’t be allowed to drive.

Once the car is paired with a particular fob, it will only receive signals from that device. Other fobs won’t work with the car, despite the fact that they look identical. This protects the integrity of the computer system that runs the car and prevents unauthorized key fobs gaining control over it.

Most dealerships with newer cars will only deal with cars with original fobs, or genuine replacements offered by the manufacturer. This is because preparing a replacement fob requires technological and security knowledge which can only be obtained in the dealer’s service department. Some aftermarket fobs, usually ones for older models with less sophisticated systems can be programmed with out the need for a dealer.
