How to Program a Key
Prior to the beginning of the 21st century the majority of cars utilized basic key systems. The keys themselves were metal and had grooves that corresponded to the internal components of the ignition cylinder. As technology advanced the number of car manufacturers began to combine physical and electronic protocols in order to prevent theft. These key systems are called transponder keys or chip keys and are designed to make it harder for thieves to open the vehicle.
The key chips that are in the keys have a specific serial number, which transmits a signal to the receiver inside your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes match, your car will begin to start. If the codes aren't compatible, your car will not even start. This is one of the primary reasons to keep a spare key for your vehicle, especially if you have an electronic transponder.

Most modern cars are equipped with a keyless entry system. To make this work the car emits radio signals that are detected by a particular key fob. The signals are compared with the code stored in the computer of the car and, if all is well the car will start to unlock. The car won't start if the signals are not the same. There are several steps you can take to program your new key fob, if it's not programmed yet.

The chip absorbs this energy and then transmits a radio frequency signal which contains an identification number. The code is matched to the unique serial numbers of the car's computers. This will prevent any unauthorised attempts to start the car, as only the correct key will be able to do so.
It is believed that this technology will be more secure than traditional keys for cars because it makes it harder for a thief to "hot wire" an automobile and start it.
