These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software, which allows them to communicate with computers.

Transponder Chips

Transponder chips can be found in cars manufactured within the last 20 years. This is the little piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.

When it is activated by an electro-magnetic field, the chip emits a low-frequency signal. The signal is then absorbed by the special antenna that is positioned around the ignition barrel of your car. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the correct one for your particular car.

This stops the vehicle from being started through hot-wiring or altering the key. The chip in the key also verifies that you are the genuine owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

Transponder keys that are regular in shape like regular keys, but with a plastic top. The chip is located inside the plastic portion of these keys. There are a variety of cuts: a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.

A circuit within the induction coil will emit a signal when the transponder is inserted into ignition barrel. The signal will be taken up by the chip, causing it to transmit a signal back to the car. If the computer in the car recognizes the signal as being correct, it will disable vehicle immobilizer, allowing the engine to start.

If the vehicle doesn't recognize the transponder signal as being the correct one, it will keep the engine from running and will alert you by flashing its lights and sounding siren. This is designed to discourage people from attempting to alter the vehicle, but it isn't a foolproof security measure. A skilled and determined thief may still be able to get around this system using a device that can intercept the signal.

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

Key Fobs

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

Key fobs communicate with each other and with the car through radio frequencies which are transmitted via an antenna in the middle of the key. This communication is encrypted to prevent others from stealing or modifying the signal.

There are a few different ways to program a key fob, based on the vehicle's make and model. You can sometimes do this yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or an additional fob.

When you press the button on a key fob the microchip transmits a signal to the receiver inside the car with which it is paired. The receiver compared the information with the 'allowed signals' stored in the key fob and then opens or locks the car's doors. If the information doesn't match the fob's information, the car won't be allowed to run.

After the car has been associated with a particular fob, it only accepts signals from that device. Other fobs will not work with the car, despite the fact that they appear like. This protects the integrity of the vehicle's computer system and to prevent the use of unauthorized key fobs to gain control over the vehicle.

The majority of newer dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is because the only place with the expertise to prepare an appropriate replacement fob is the service department of the dealer. Certain aftermarket fobs, typically those from older models with less sophisticated systems can be programmed without the need for a dealer.
