These are handheld devices 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 was built in the last 20 years, chances are it has a transponder inside of it. It's the tiny plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.

The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then taken up by the antenna that is positioned around the ignition barrel of your vehicle. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the right one for your vehicle.

This prevents the vehicle from starting by either hot-wiring or by tampering. The chip in the car key confirms that the owner is the person who owns the vehicle. This can help to reduce the possibility of theft from your vehicle.

Regular transponder keys are shaped like regular keys, but with an outer layer of plastic. The chip is contained within the plastic part of the keys. There are several different cuts such as a standard cut Laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is received by the chip which then transmits a signal to the vehicle. If the computer onboard the car is able to recognize the signal as valid it will turn off the vehicle immobilizer to allow the engine start.

If the vehicle doesn't recognize the transponder signal as being the proper one, it will prevent the engine from running and will alert you by flashing its lights and sounding an alarm. This is designed to discourage people from trying to tamper with the vehicle, however it's not a 100% security measure. A skilled and determined thief may still be able to bypass this system by employing a device designed to detect the signal.

It is evident that the transponder is an excellent option. All car owners must take this into consideration in order to safeguard their investment and reduce theft risk.

Key Fobs

In addition to locking and unlocking doors, starting the car from a distance or making noises to aid in finding the car in a parking lot, today's key fobs can also turn on a heated steering wheel, or roll down all windows with just a single click. These additional features can make it difficult to locate your car keys.

Key fobs communicate with each with the car via radio frequencies that are transmitted through an antenna in the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and retransmitting the signal.

You can program a keyfob in different ways based on the model and brand of your vehicle. Some cars allow you to do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer for them program a replacement key fob or additional one.

When you press the button on your key fob, the microchip inside transmits a code to the car's receiver that it is linked to. The receiver then compares the data with the 'allowed signals' stored in the key fob and then locks or opens the car's doors. If the information doesn't match the signals, the car will not be allowed to run.

Once the car has been connected to a specific fob, program it only accepts signals from the device. Other fobs will not work with the car, despite the fact that they appear identical. This helps to protect the integrity of the car's computer system and to prevent unauthorised key fobs from taking control over the vehicle.

The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements supplied 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. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by customers without the need for an authorized dealer.
