A keyprogrammer is a tool which can reprogram the transponder chip in a new mechanical or key fob key. It is also able to copy the data from an existing key which allows duplicate keys to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that enables them to communicate with the computer, and they also have a bidirectional interface for working with the immobilizer system.

Transponder Chips
Transponder chips can be found in vehicles manufactured within the past 20 years. This is the little plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then absorbed by a special antenna attached to the ignition barrel. The computer system of the vehicle will then confirm that the transponder chip of the key is the correct one for your car.
This is what stops doing hot-wiring or altering the ignition system of the vehicle to turn it on. The chip in the key also confirms that you are the genuine owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
Transponder keys that are regular in shape like regular metal keys with a plastic top. The chip is contained within the plastic portion of the keys. There are various cuts such as a standard cut Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal is taken up 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 disable the vehicle immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will stop the engine from starting and will alert you by flashing its lights and sounding siren. This feature is designed to discourage people from trying to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and determined thief may still be able to escape this security system by using a device that can detect the signal.
You can see that a transponder is a great option. All car owners must take this into consideration if they wish to protect their investment and decrease the chance of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making noises to aid in finding a car in a parking space Key fobs today can also turn on a heated steering wheel, or open all windows with a single press. These additional features could make it difficult to locate your car keys.
Key fobs communicate with one other and the car using radio frequencies which are transmitted via an antenna that is located in the center of the key. The signal is encrypted to prevent others from stealing or stealing the signal.
There are programming car key to program a key fob depending on the vehicle's make and model. 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 an additional fob.
When you press a key fob's button the microchip inside sends a code to the car's radio that it is linked to. The receiver compared the information with the 'allowed signals' that are stored on the key fob and then opens or locks the car door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to function.
After 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, despite the fact that they appear identical. This ensures the security of the computer system that runs the vehicle and stops unauthorised key fobs from taking control over it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are 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 ones for older models with less sophisticated systems, can be programmed without the need for a dealer.
