These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with a computer.

Transponder Chips

Transponder chips are likely to be found in vehicles manufactured within the past 20 years. This is a little piece of plastic on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.

When activated by an electro-magnetic field the chip emits a low-frequency signal. This signal then gets taken up by the antenna that is attached to the barrel that controls your ignition in your car. This allows the vehicle's computer system to verify that the transponder chip inside the key is the correct one for your particular car.

This prevents the vehicle from being started by either hot-wiring or by tampering. The chip in the key also confirms that you are the genuine owner of the vehicle. This helps to prevent car theft.

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

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer onboard the car recognizes the signal as valid it will turn off the car immobilizer so that the engine can start.

If the car key programmers isn't able to recognize the transponder as being the proper signal, it won't start the engine and will alert you with flashing lights and an alarm. This is designed to deter people from trying to tamper with the vehicle, however it isn't a foolproof security measure. A skilled and committed thief might be able bypass this system by using a special device to detect the signal.

It is evident that a transponder is a great option. This is something that all vehicle owners should consider if they want to safeguard their investment and minimize the risk of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find the car in a parking lot keys of today can also switch on the heated steering wheel or roll down all windows with just a single push. A lot of these additional features might seem useful but they could make it harder for you to keep the track of your car keys.

Key fobs make use of radio frequencies to communicate with one another and with the car. The frequencies are transmitted by a small antenna within the middle of the key. The signal is encrypted to prevent others from intercepting or replicating the signal.

Keyfobs can be programmed in various ways based on the make and model of your vehicle. You can sometimes do this yourself, however most modern vehicles require a dealer or professional locksmith to program a replacement or additional fob.

When you hit the button on a key fob it transmits a code to the car's receiver it is linked to. The receiver then compares this information with the signals that are allowed on the fob and either locks or opens the door. If the information doesn't match, a chirping sound is heard and the car isn't allowed to operate.

Once the car is linked with a particular fob, it will only accept signals from the device that is associated with it. Other fobs won't work with the car, even though they look similar. This protects the integrity of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control of it.

The majority of newer dealerships will only work with cars with original fobs, or genuine replacements offered by the manufacturer. It is because the only place with the expertise to prepare the replacement fob is the service department of the dealer. However, some fobs from the aftermarket typically for older models that have less sophisticated systems -- can be programmed by customers without the need for dealers.
