Keyprogrammers can recode the transponder chip of a new mechanical key or key fob. It is also able to clone information from an existing key which allows duplicate keys to be made. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that enables them to communicate with computers as well as an interface that works bidirectionally with the immobilizer system.

Transponder Chips
If your car was manufactured in the last 20 years, it is likely that it has a transponder chip inside of it. This is the little plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is received by a specific antenna attached to the barrel of ignition. The computer system of the vehicle can then verify that the chip in the key's transponder is the correct one for your vehicle.
This is what prevents doing hot-wiring or altering the ignition system of the vehicle to get it started. The chip inside the car key confirms that the owner is the one who is the owner of the vehicle. This can reduce car theft.
Transponder keys resemble regular metal keys, but with caps made of plastic. The chip is contained within the plastic part of these keys. There are a variety of cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
The circuit in the induction coil emits signals when the transponder is placed in the an ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the car's computer recognizes this signal as the correct one, it will disable the vehicle's immobilizer and allow the engine to start.
If the car isn't able to recognize the transponder as a valid signal, it will not start the engine and notify you via flashing lights and a siren. This feature is intended to discourage people from trying to alter the vehicle, however it is not a foolproof security measure. A skilled and determined criminal may still be able to escape this security system by using a special device to take over the signal.
You can see that a transponder is a great option. All car owners must take this into consideration when they want to safeguard their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely or making sound chirps to help locate the car in a parking space Key fobs today can also switch on a heated steering wheel, or roll down all windows with just a single press. A lot of these additional features may seem convenient however they could make it harder for you to keep the keys to your car.
Key fobs communicate with each other and with the car through radio frequencies that are transmitted through a small antenna located in the middle of the key. This communication is encrypted, which helps stop others from stealing and re-transmitting the signal.
Keyfobs can be programmed in different ways based on the make and model of your car. You can sometimes do this yourself, but most newer vehicles require a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on your key fob the microchip inside sends an informational code to the car's radio that it is paired with. The receiver compares the information with the 'allowed signals' that are stored on the key fob and then locks or opens the car's door. If the information doesn't match the signals, the car will not be allowed to drive.
When a car is connected with a specific fob it will only receive signals from that device. Other fobs won't work with the car, despite the fact that they look like. This is to safeguard the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise that is only available in the dealer's service department. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems -- can be programmed by the consumer without the need of an authorized dealer.
