It is recommended to have two keys that are compatible with your current car so you can program the replacement key whenever needed.
A keyprogrammer is a device which can reprogram the transponder chip into an entirely new mechanical or key fob key. It is also able to copy the information from an existing key, allowing duplicates to be created. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that allows 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 past 20 years, it is likely that it has a transponder chip inside of it. It's a small plastic piece inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is taken up by an antenna that is attached to the ignition barrel. The computer system of the vehicle will then confirm that the chip in the key's transponder is the right one for your car.
This is what prevents hot-wiring or tampering with the ignition system of your vehicle to turn it on. The chip in the key also verifies that you are the legal owner of the vehicle. This can reduce car theft.
Regular transponder keys are shaped like regular keys and have an outer layer 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.
A circuit inside the induction coil will emit signals when the transponder is placed in the the ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer on the car detects this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder as being the proper signal, it won't start the engine, and will notify you via flashing lights and a siren. This function is designed to discourage those who would attempt to alter the vehicle. However it isn't a foolproof measure of security. A skilled and committed thief may still be able to get around this system employing a device designed to intercept the signal.
You can see that the transponder is a good option. Every car owner should consider this if they wish to protect their investment and minimize the chance 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 lot keys of today can also switch on the heated steering wheel or roll down all of the windows with just a single push. Many of these extra features might seem useful but they could make it more difficult to keep track of your car keys.
Key fobs make use of radio frequencies to communicate with one another and with the car. The frequencies are transmitted via a small antenna that is located within the middle of the key. The communication is encrypted, which helps prevent others from intercepting and replicating the signal.
There are many ways to program a key fob, based on the vehicle's make and model. Some cars allow you to do it yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a replacement key fob or an additional one.
When you hit the button on a key fob the microchip inside sends a code to the car's radio that it is paired with. The receiver then compares the data with the permitted signals stored in the key fob and then locks or opens the car's door. If the information does not match the signals, the car will not be allowed to operate.
Once the car is paired with a specific fob, it will only accept signals from that device. Other fobs will not work with the car, even though they look identical. This protects the integrity of the computer system that runs the car and blocks unauthorised key fobs from taking control of it.
The majority of newer dealerships will only work with cars with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge that is only available in the dealer service department. However, some fobs from the aftermarket typically for older models with less sophisticated systems -- can be programmed by the consumer without the need for dealers.
