Keyprogrammers can recode the transponder chip of an entirely new mechanical key or key fob. It also can clone the data of an existing key in order to create duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. programming car key are equipped with diagnostic software, which allows them to communicate with computers.

Transponder Chips

Transponder chips are likely be found in cars that were manufactured within the last 20 years. It's a small plastic piece in the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.

When it is activated by an electromagnetic field, the chip emits a low-frequency signal. The signal is received by a specific antenna attached to the barrel of ignition. This allows the vehicle's computer system to confirm that the transponder chip inside the key is the right one for your particular car.

This prevents the vehicle from being started through hot-wiring, or by altering the key. The chip inside the key confirms that the owner is the person who is the owner of the vehicle. This helps to reduce the risk of theft from your car.

Transponder keys resemble regular keys made of metal, but with caps made of plastic. The chip is housed inside the plastic portion of the key, and there are different kinds of cuts available on these keys: a regular standard cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.

A circuit within the induction coil emits signals when the transponder is put into the ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer on the car detects this signal as the right one, it will shut down the immobilizer on the vehicle and allow the engine to start.

If the car doesn't recognize the transponder as a valid signal, it won't start the engine, and will notify you via flashing lights and an alarm. This system is designed to deter people from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and determined thief could still bypass this system by using a specific device that detects 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 are looking to safeguard their investment and reduce the chance of theft.

Key Fobs

Key fobs today can do more than just lock and unlock doors. They can also start the car remotely, make chirping noises to help locate the car, or turn on the heated steering wheel. A lot of these additional features might seem useful, but they can also make it harder for you to keep the track of your car keys.

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

You can program a keyfob in a variety of ways depending on the model and make of your vehicle. Certain models allow you to do it yourself. However, most newer models require you to visit a professional locksmith or dealer to program a new key fob, or an alternative one.

When you press a key fob's button the microchip inside sends an encoded code to the car's receiver it is linked to. The receiver compared this information to the 'allowed' signals in the fob and then either opens or closes the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.

After the car has been associated with a particular fob, it only accepts signals from the device. Other fobs will not work with the car, despite the fact that they appear identical. This safeguards the integrity of the computer system in the car and prevents unauthorised key fobs from taking control over it.

Most newer car dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. The reason for this is that the only place that has the experience to design the replacement fob is the service department of a dealer. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by consumers without the need for dealers.
