Transponder Chips

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

When it is activated by an electro-magnetic field the chip emits a low-level signal. The signal is then received by a specific antenna that is attached to the barrel of ignition. The computer system in the vehicle will then confirm that the key's transponder chip is the right one for your car.

This is what stops from modifying or hot-wiring the vehicle's ignition system to get it started. The chip inside the car key confirms that the owner is the person who owns the vehicle. This can reduce car theft.

Transponder keys resemble regular metal keys but have a plastic cap. The chip is located inside the plastic part of these keys. There are several different cuts such as a standard cut laser cut (also called a sidewinder or Ford Tibbe), and the Ford Tibbe.

A circuit within the induction coil will emit a signal when the transponder is inserted into an ignition barrel. The signal will be taken up by the chip and cause it to send a signal back to the car. If the onboard car computer recognizes this signal as being the correct one, it will turn off the vehicle immobilizer and allow the engine to start.

If the car doesn't recognize the transponder as a valid signal, it will not start the engine and notify you via flashing lights and a siren. This feature is designed to discourage people from trying to alter the vehicle, but it is not a foolproof security measure. A determined and skilled thief could still bypass this system by using a specific device that detects the signal.

It is evident that a transponder is a great option. This is something that all car owners should consider if are looking 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 sound chirps to help locate the car in a parking space, today's key fobs can also activate the heated steering wheel or open all windows with a single button push. A lot of these additional features may appear convenient, but they can also make it harder for you to keep the keys to your car.

Key fobs use radio frequencies to connect with one another and with the car. These frequencies are transmitted by a small antenna inside the middle of the key. The transmission is encrypted, which helps to stop others from stealing and replicating the signal.

There are many ways to program a key fob depending on your vehicle's make and model. It is possible to do this yourself, but most newer automobiles require a dealer or professional locksmith to program a replacement or additional fob.

When you hit the button on a key fob the microchip inside sends an informational code to the car's receiver it is paired with. The receiver compares this information with the signals that are allowed on the fob and either opens or locks the door. If the information doesn't match, the car will not be allowed to drive.

Once the car has been associated with a particular fob, it only accepts signals from the device. Other fobs will not work with the car, even if they look identical. This helps to protect the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle.

Most newer car dealerships will only work with vehicles that have original fobs, or genuine replacements offered by the manufacturer. It is because the only place with the experience to design an appropriate replacement fob is the service department of the dealer. 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.
