A keyprogrammer is a tool that recodes the transponder chip in an entirely new mechanical or key fob key. It also can clone the data of an existing key to make duplicates. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with a computer.

Transponder Chips

If your car is made within the last 20 years, chances are it contains a transponder chip within of it. It's a tiny piece of plastic in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by an antenna attached to the barrel of ignition. The computer system in the vehicle can then verify that the key's transponder chip is the correct one for your car.

This is what prevents doing hot-wiring or altering the ignition system of your vehicle to turn it on. The chip in the key also proves that you are the legal owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

Transponder keys appear like regular metal keys, but with a plastic cap. The chip is contained inside the plastic portion of the key and there are a few different kinds of cuts available on these keys: a regular standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer in the car is able to recognize the signal as correct it will turn off the vehicle immobilizer to allow the engine start.

If the car 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 a siren. This feature is designed to discourage people from trying to hack into the vehicle, however it is not a foolproof security measure. A skilled and determined criminal could still be able to bypass this system by employing a device designed to intercept the signal.

As you can see there are quite a number of advantages to having a transponder key. This is something that all vehicle owners should consider if they want to safeguard their investment and minimize the risk of theft.

Key Fobs

Key fobs today can do more than just lock and unlock doors. They can also turn on the vehicle remotely, make chirping noises to help locate the car, or switch on the heated steering wheel. A lot of these features may seem convenient however they could make it difficult for you to keep track of your car keys.

Key fobs utilize radio frequencies to communicate with one another and the car. These frequencies are transmitted through a small antenna located inside the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and replicating the signal.

There are several ways to program a key fob depending on the make and model. Certain cars let you do this yourself. However, the majority of newer models require you to visit a professional locksmith or dealer to program a replacement key fob or an additional one.

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

Once the car has been connected to a specific fob, it can only receive signals from that device. Other fobs will not work with the car, even though they look similar. This protects the integrity of the computer system of the car and blocks unauthorized key fobs gaining control over it.

The majority of newer dealerships will only accept cars with original fobs or genuine replacements 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 that are typically designed for older models with less sophisticated systems can be programmed by consumers without the need for a dealership.
