It's best to have two keys that are compatible for the modern automobile so that you can program the replacement key when needed.
A keyprogrammer can reprogram the transponder chip of an entirely new mechanical key or key fob. It also can clone information from an existing key to make duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with a computer. They also have a bidirectional user interface for working with an immobilizer system.
There are a variety of keyprogrammers that are available on the market. They are available in a variety of sizes, shapes and colors.

Transponder Chips
Transponder chips can be found in cars manufactured within the past 20 years. It's a tiny plastic thing in the head of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
When activated by an electro-magnetic field the chip emits a low-level signal. The signal is taken up by an antenna that is attached to the barrel of ignition. This allows the vehicle's computer system to confirm that the transponder chip in the key is the right one for your specific vehicle.
This stops the vehicle from being started by either hot-wiring or by altering the key. The chip inside the key also verifies that you are the genuine owner of the vehicle. This can help to reduce car theft.
Transponder keys look like normal keys but have a plastic cap. The chip is housed within the plastic part of the key, and there are a few different types of cuts on these keys: a cut laser cut (also called a sidewinder key) or Ford Tibbe key.
A circuit within the induction coil emits an electrical signal when the transponder is placed in the the ignition barrel. The signal will then get taken up by the chip, causing it to transmit a signal to the car. If the computer inside the car detects the signal as being correct it will turn off the car immobilizer, allowing the engine to start.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine and warn you with flashing lights and a siren. This is designed to discourage people from trying to tamper with the vehicle, however it's not a 100% security measure. A skilled and determined thief may still be able to get around this system employing a device designed to take over the signal.
As you can see there are quite number of advantages to having transponder keys. All car owners should consider this if they wish to protect their investment and reduce the chance of theft.
Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also turn on the car remotely, emit chirping sounds to aid in finding a car or turn on the heated steering wheel. These additional features could make it difficult to find your car keys.
Key fobs make use of radio frequencies to communicate with one another and the car. These frequencies are sent via a small antenna that is located within the middle of the key. This communication is encrypted to block other key fobs from intercepting or replicating the signal.
There are several ways to program a key fob depending on your vehicle's make and model. Certain cars let you do this by yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order for them program a replacement key fob, or an alternative one.
When you press the button on a key fob the microchip transmits a signal to the receiver inside the car with which it is paired. The receiver then compares this information to the 'allowed' signals on the fob and either locks or opens the door. If the information doesn't match the fob's information, the car won't be allowed to drive.
Once the car has been associated with a particular fob, it only accepts signals from that device. Other fobs won't work with the car, even though they look identical. This is to safeguard the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
Most newer car dealerships will only work with cars that have original fobs, or genuine replacements supplied by the manufacturer. It is because the only place that has the knowledge to create a replacement fob is in a dealer's service department. Some fobs from the aftermarket, especially ones for older models that have less sophisticated systems can be programmed without the need for a dealership.
