These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port.

Transponder Chips

Transponder chips are likely be found in cars that were manufactured within the past 20 years. This is a little plastic thing inside the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.

When it is activated by an electro-magnetic field, the chip emits a low level signal. This signal then gets amplified by the specific antenna that is fitted around the barrel that controls your ignition in your vehicle. The computer system of the vehicle can then verify that the key's transponder chip is the right one for your car.

This prevents the vehicle from starting by hot-wiring, or by tampering. The chip in the car key ensures that the owner is the one who owns the vehicle. This will help reduce car theft.

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

A circuit inside the induction coil emits signals when the transponder is inserted into an ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the car's computer recognizes this signal as being the right one, it will turn off the vehicle's immobilizer and allow the engine to start.

If automotive key programming isn't able to recognize the transponder as the correct signal, it will not start the engine and will alert you with flashing lights and a siren. This feature is designed to discourage people from attempting to alter the vehicle, however it's not a 100% security measure. A skilled and determined criminal could still be able to get around this system using a special device to intercept the signal.

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

Key Fobs


Key fobs today offer more than locking and unlock doors. They can also turn on the vehicle remotely, make chirping noises to help locate a car, or switch on the heated steering wheel. A lot of these additional features might seem useful however they could make it more difficult to keep track of your car keys.

Key fobs make use of radio frequencies to communicate with each other and with the car. These frequencies are transmitted through a small antenna located within the middle of the key. This signal is encrypted to prevent others from stealing or stealing the signal.

There are many ways to program a key fob based on the model and make. You may be able to do it yourself, but the majority of newer cars require that you visit a locksmith shop or a professional to program a replacement or additional fob.

When you press the button on your key fob, the microchip inside transmits a code to the car's receiver it is linked to. The receiver then compares this information with the signals that are allowed in the fob and then either locks or opens the door. If the data does not match the signals, the car will not be allowed to drive.

Once the car is linked with a particular fob, it will only accept signals from the device that is associated with it. In turn, other fobs won't work with the vehicle, even though they have the same appearance. This helps to protect the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.

Most newer car dealerships will only deal with cars with original fobs, or genuine replacements offered by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security expertise that is only available in the dealer's service department. Some aftermarket fobs, usually ones for older models with less sophisticated systems can be programmed with out the need for a dealership.
