The key may not work properly or not start the vehicle at all. This is because the key hasn't yet been programmed into the car's system. This can be costly. This is why it's a great idea to have two working keys for modern vehicles and to have the replacement key programmed if required.
A keyprogrammer is a tool that recodes the transponder chip into the form of a new mechanical or key fob key. It also can clone the data of an existing key in order 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 a computer. They also have a bidirectional interface that works with an immobilizer system.

Transponder Chips
If your car was manufactured in the last 20 years, chances are it contains a transponder chip within of it. It's a small plastic piece in the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When it is activated by an electro-magnetic field the chip emits a low-frequency signal. This signal then gets absorbed by the special antenna that is attached to the barrel that controls your ignition in your car. This allows the computer in your vehicle system to determine if the transponder chip in the key is the correct one for your particular car.
This prevents the vehicle from being started through either hot-wiring or by altering the key. The chip inside the key also confirms that you are the genuine owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Transponder keys appear like regular keys made of metal but they have a plastic cap. The chip is located inside the plastic portion of the keys. There are various cuts: a standard cut, laser cut (also known as 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 an electrical signal. 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 disable the vehicle immobilizer and allow the engine to start.
If the vehicle does not recognize the transponder signal as being the correct 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 a foolproof measure of security. A determined and skilled thief could still bypass this system with a specially designed device that detects the signal.
As you can see there are quite a number of benefits to having a transponder key. This is something that all car owners should consider if they want to safeguard their investment and decrease the chance of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also turn on the car remotely, emit chirping sounds to help locate the car, or switch on the heated steering wheel. Many of these extra features may appear convenient, but they can also make it difficult for you to keep track of your car keys.
Key fobs make use of radio frequencies to connect with one another and with the car. These frequencies are sent through a small antenna located in the middle of the key. The signal is encrypted to block other key fobs from stealing or modifying the signal.
You can program a keyfob in different ways based on the model and make of your car. Certain models allow you to do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order to program a replacement key fob or an additional one.
When you press the button on your key fob, the microchip inside transmits an encoded code to the car's radio that it is linked to. The receiver compared this information with the 'allowed' signals inside the fob, and either locks or opens the door. If the information does not match the signals, the car will not be allowed to operate.
Once the car is paired with a particular fob, it will only accept signals from that device. This means that other fobs will not work with the vehicle even if they appear similar. This safeguards the integrity of the computer system in the vehicle and stops unauthorised key fobs from taking control of it.
Most dealerships with newer cars will only accept cars that have original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place that has the experience to design an appropriate replacement fob is the service department of the dealer. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by consumers without the need for dealers.
