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

Transponder Chips

Transponder chips are likely to be found in vehicles manufactured within the last 20 years. It's the small piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your vehicle.

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then absorbed by a special antenna attached to the ignition barrel. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the correct one for your particular car.

This stops the vehicle from being started through hot-wiring or tampering. The chip inside the key also confirms that you are the legal owner of the vehicle. This helps to prevent car theft.

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

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

If the car keys programming doesn't recognize the transponder as being the proper signal, it won't start the engine and notify you via flashing lights and an alarm. This feature is designed to deter people from trying to alter the vehicle, however it is not a foolproof security measure. A skilled and determined thief may still be able to get around this system employing a device designed to intercept the signal.

As you can see there are quite number of advantages to having transponder keys. All car owners should take this into consideration if they wish to protect their investment and decrease theft risk.

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 Key fobs today can also turn on a heated steering wheel or open all windows with a single button push. These extra features can make it difficult for you to find your car keys.

Key fobs communicate with each other and with the car through radio frequencies which are transmitted by a small antenna located in the center of the key. This communication is encrypted to stop others from stealing or modifying the signal.

There are several ways to program a key fob based on the vehicle's model and make. You can sometimes do this yourself, however most modern cars require that you visit a locksmith shop or a professional to program a replacement or additional fob.

When you press the button on a key fob, the microchip transmits signals to the receiver in the vehicle with which it is paired. The receiver compares this information with the 'allowed' signals in the fob and then either opens or locks the door. If the information doesn't match the fob's information, the car won't be allowed to drive.

When a car is connected with a specific fob it will only accept signals from that device. Other fobs will not work with the car, even though they look similar. This protects the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.

The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security skills which can only be obtained in the dealer service department. Some aftermarket fobs, usually those from older models that have less sophisticated systems can be programmed with out the need for a dealer.
