How to program a Key
Up until the turn of the 21st century, the majority of cars had basic key systems. The keys themselves were metal and had grooves that corresponded to the internal components of the ignition cylinder. As time went on and technology improved as it did, automobile manufacturers began to combine electronic and physical protocols to stop theft. These key systems are called transponder keys or chip keys, and they're designed to make it difficult for thieves to start the vehicle.
The key chips contain an unique serial number that transmits a message to the receiver inside your car. The signal is then compared to an identifier in the car's computer when it is received. If the codes are identical, your car will begin to start. If the codes don't match, then your car won't even start. This is one of the main reasons why you should always keep a spare key on your car, especially when you use transponder-based systems.
You'll require special equipment to learn to program keys. You'll also need to purchase an uncut key for your specific make and model.

The chip absorbs the energy and then transmits a radiofrequency signal that contains an identification code. This code matches the unique digital serial numbers in the computer of the car. This prevents unauthorised attempts to start the car as only the proper keys will be able to do so.
This technology is believed to be more secure than traditional keys for cars because it makes it much harder for a thief to "hot wire" a vehicle and get it started.
