How to program a key

Before the turn of the 21st century, the majority of cars had basic key systems. The keys themselves were metal and had grooves that matched the internal components of the ignition cylinder. As technology improved, more and more car makers began to mix electronic and physical protocols in order to prevent theft. Key systems like these also known as transponder keys or chips keys, are designed to make it difficult for thieves to start a vehicle.

The key chips contain unique serial codes that transmits a message to the receiver in your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes are identical the car will begin to begin to start. If the codes aren't compatible, your car will not even start. This is one of the primary reasons why you should always keep a spare key for your car, especially when you use transponder-based systems.

The chip absorbs the energy and then sends a radio frequency signal that includes an identification code. This code is in line with the unique digital serial numbers in the car's computers. This is to prevent unauthorised attempts to start the car as only the correct keys will be able.

It is believed that this technology will be more secure than conventional car keys because it makes it much harder for a thief to "hot wire" the vehicle and get it started.
