They have diagnostic software that allows them to communicate with the computer as well as bidirectional interfaces to work with the immobilizer system.

Transponder Chips

If your car was manufactured within the last 20 years, it is likely that it contains a transponder chip within of it. It's a small plastic piece on the back of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.

The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is taken up by an antenna that is 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 vehicle.

This is what stops hot-wiring or tampering with the ignition system of your vehicle to get it started. The chip inside the key also proves that you are the legal owner of the vehicle. This helps to reduce the risk of theft from your car.

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

A circuit inside the induction coil emits a signal when the transponder is placed in the the ignition barrel. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the computer onboard the car detects the signal as correct it will turn off the car immobilizer to allow the engine start.

If the vehicle doesn't recognize the transponder signal as being the proper one, it will stop the engine from starting and will notify you by flashing its lights and sounding a siren. This system is designed to deter people from tampering with the vehicle. However, it is not an absolute security measure. A skilled and determined thief may still be able to get around this system employing a device designed to intercept the signal.

You can see that the transponder is a good option. This is something that all car owners should think about if they are looking to safeguard their investment and decrease the risk of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely, or making noises to aid in finding a car in a parking lot, today's key fobs can also turn on the heated steering wheel or roll down all windows with a single button click. A lot of these additional features might seem useful but they could make it difficult for you to keep the keys to your car key cut and programed.

Key fobs use radio frequencies to communicate with one another and the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. The communication is encrypted, which helps stop others from stealing and replicating the signal.

There are several ways to program a key fob depending on the model and make. It is possible to do this yourself, but the majority of newer cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob.

When you press the button on your key fob, the microchip inside transmits an informational code to the car's receiver it is linked to. The receiver compares this information with the 'allowed' signals stored in the fob and then either locks or opens the door. If the information isn't in line, a chirping sound is heard and the car isn't permitted to operate.

Once the car is paired with a specific fob it will only receive signals from that specific device. In turn, other fobs won't work with the vehicle even though they look the same. This safeguards the integrity of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control of it.

The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security expertise that can only be found in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by customers without the need of an authorized dealer.
