The key might not function correctly or will not start the vehicle at all. This is because the key has not yet been programmed into the vehicle's system. This can be expensive. This is why it's a great idea to have two working keys for a modern automobile and to have the replacement key programmed if necessary.
Keyprogrammers can recode the transponder chip on a new mechanical key or key fob. It also can clone the data of an existing key to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with computers.

Transponder Chips
If your car was built within the past 20 years, chances are it contains a transponder chip within of it. It's the tiny piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is received by a specific antenna that is attached to the ignition barrel. This allows the vehicle's computer system to verify that the transponder chip in the key is the right one for your specific vehicle.
This is what prevents from modifying or hot-wiring the vehicle's ignition system to start it. The chip in the key also verifies that you are the genuine owner of the vehicle. This helps to prevent car theft.
Transponder keys resemble regular metal keys but have a plastic cap. The chip is housed in the plastic portion of the key and there are different types of cuts on these keys: a cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
The circuit in the induction coil will emit an electrical signal when the transponder is put into an ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer inside the car is able to recognize the signal as being correct it will turn off the car immobilizer, allowing the engine to start.
If the car doesn't recognize the transponder as a valid signal, it will not start the engine, and will warn you with flashing lights and siren. This feature is intended to discourage people from trying to tamper with the vehicle, but it's not a 100% security measure. A skilled and committed thief could still be able to escape this security system by using a special device to detect the signal.
It is evident that the transponder is an excellent option. Every car owner should take this into consideration when they want to safeguard their investment and reduce theft risk.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making sound chirps to help locate the car in a parking space Key fobs today can also activate a heated steering wheel, or open all windows with just a single push. A lot of these additional features might seem useful but they could make it harder for you to keep track of your car keys.
Key fobs communicate with one other and with the car through radio frequencies that are transmitted via an antenna in the middle of the key. This communication is encrypted, which helps stop others from stealing and retransmitting the signal.
There are a few different ways to program a key fob based on your vehicle's model and make. Certain cars let you do it yourself. However, most newer models require you to visit an expert locksmith or dealer for them program a replacement key fob, or an alternative one.
When you press the button on your key fob, the microchip inside transmits an informational code to the car's receiver that it is linked to. The receiver compared this information to the 'allowed' signals stored inside the fob, and either opens or closes the door. If the information isn't in line, a chirping sound is heard and the car isn't permitted to operate.
Once the car is paired with a specific fob, it can only receive signals from that device. As a result, other fobs won't work with the vehicle, even though they appear similar. This protects the integrity of the computer system in the car and prevents unauthorised key fobs from taking control of it.
Most dealerships with newer cars will only deal with vehicles that have original fobs, or genuine replacements supplied by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security skills that can only be found in the dealer service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by the consumer without the need for a dealership.
