How do you program a key?
Before the turn of the 21st century, the majority of cars had basic key systems. Keys were made from metal and incorporated grooves to correspond to the internal parts in the ignition cylinder. As technology advanced, more and more car makers began to mix physical and electronic protocols to stop theft. These key systems are known as transponder keys or chip keys, and they're designed to make it harder for thieves to get into the vehicle.
The key chips come with a unique serial code that sends a message to the receiver inside your car. The signal is compared with the car's computer when it is received. If the codes are compatible, then your car will begin to start. If not, it won't start at all. This is the reason you should keep a spare car key, particularly if your system is transponder-based.

This helps prevent unauthorised attempts to start the car as only the correct key will be able to do so.
The technology is believed to be more secure than traditional car keys because it makes it much difficult for thieves to "hot wire" the vehicle and get it started.
