It is best to have two keys that work for the modern automobile so that you can program the replacement key if needed.
A keyprogrammer can reprogram a transponder chip on a new mechanical key or key fob. It is also able to copy the data of an existing key and allow duplicate keys to be created. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They have diagnostic software that allows them to communicate with the computer, and they also have a bidirectional interface for working with the immobilizer system.

Transponder Chips
If your car was manufactured within the last 20 years, chances are it has a transponder inside of it. It's a tiny plastic piece inside the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
When it is activated by an electromagnetic field, the chip emits a low-level signal. The signal is then absorbed by a special 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 key programmer is the correct one for your vehicle.
This prevents the vehicle from being started by hot-wiring or tampering. The chip inside the key also verifies 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 keys made of metal, but with a plastic cap. The chip is contained within the plastic portion of these keys. There are a variety of cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe), and Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer onboard the car recognizes the signal as valid it will turn off the vehicle immobilizer to allow the engine start.
If the car does not recognize the transponder signal as the right one, it will prevent the engine from running and will notify you by flashing its lights and sounding siren. This system is designed to deter people from tampering with the vehicle. However it's not an absolute security measure. A skilled and determined thief could still be able to get around this system using a special device to intercept the signal.
It is evident that the transponder is a good option. This is something that all vehicle owners should consider if they want to safeguard their investment and reduce the chance of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also turn on the car from a distance, make chirping sounds to help locate the car or turn on the heated steering wheel. A lot of these features might seem useful but they could make it difficult for you to keep the track of your car keys.
Key fobs make use of radio frequencies to communicate with each other and with the car. The frequencies are transmitted via a small antenna that is located inside the middle of the key. This communication is encrypted to block other key fobs from stealing or stealing the signal.
There are a few different ways to program a key fob based on your vehicle's make and model. You may be able to do it yourself, however most modern automobiles require a dealer or professional locksmith to program a replacement or an additional fob.
When you press a key fob's button, the microchip inside transmits a code to the car's receiver it is paired with. The receiver compares the information with the 'allowed signals' stored in the key fob, and then it opens or closes the car's door. If the data does not match the signals, the car will not be allowed to run.
After the car has been paired with a specific fob, it only accepts signals from the device. Other fobs will not work with the car, even though they appear like. This is to safeguard the integrity of the car's computer system, and also to stop unauthorized key fobs from gaining control of the vehicle.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security skills that is only available in the dealer's service department. Some fobs from the aftermarket, especially those for older models that have less advanced systems, can be programmed without the need for a dealership.
