These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with computers as well as an interface that works bidirectionally with the immobilizer system.

Transponder Chips

If your car is made within the past 20 years, then it has a transponder inside of it. It's the small piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.

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

This stops the vehicle from being started through hot-wiring, or by altering the key. The chip inside the car key verifies that the owner is the one who owns the vehicle. This can reduce car theft.

Regular transponder keys are shaped like regular keys, but with an outer layer of plastic. The chip is housed in the plastic portion of the key, and there are a few different types of cuts on these keys: a standard cut laser cut (also called a sidewinder key), or a Ford Tibbe key.

A circuit within the induction coil will emit a signal when the transponder is placed in the the ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the onboard car computer detects this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to begin.

If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine and warn you with flashing lights and a siren. This system is designed to deter individuals from tampering with the vehicle. However it's not an absolute security measure. A skilled and determined thief can still get around this system using a special device that detects the signal.

As you can see there are quite a number of advantages to having a transponder key. This is something that all vehicle owners should consider if they want to safeguard their investment and reduce the chance of theft.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding a car in a parking space, today's key fobs can also turn on the heated steering wheel or roll down all windows with just a single push. These extra features could make it difficult to find your car keys.

Key fobs utilize radio frequencies to communicate with one another and the car. These frequencies are sent via a small antenna that is located inside the middle of the key. This signal is encrypted to stop others from stealing or modifying the signal.

There are a few different ways to program a key fob depending on your vehicle's make and model. Certain models allow you to do it yourself. However, most newer models require you to visit a professional locksmith or dealer to program a replacement key fob or an additional one.

When you press the button on your key fob, the microchip inside transmits an encoded code to the car's receiver that it is linked to. The receiver compared the information with the permitted signals stored on the key fob and then it opens or closes the car's doors. If the data does not match the fob's information, the car won't be allowed to run.

Once the car is linked with a specific fob it will only accept signals from the device that is associated with it. As a result, other fobs will not work with the vehicle even though they appear similar. This ensures the security of the computer system that runs the car and prevents unauthorized key fobs gaining control of it.

Most dealerships with newer cars will only deal with cars with original fobs or genuine replacements supplied by the manufacturer. This is because the only place that has the expertise to prepare a replacement fob is in the service department of a dealer. Some fobs from the aftermarket, especially ones for older models with less sophisticated systems can be programmed with out the need for a dealer.
