How to program the key Up until the turn of the 21st century the majority of cars utilized 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 automobile makers began to combine physical and electronic protocols to avoid theft. These key systems are known as transponder keys or chip keys and they're designed to make it more difficult for thieves to get into the vehicle. The key chips come with a unique serial code which transmits a signal to the receiver in your car. The signal is compared to a code in the computer of the car when it is received. If the codes are compatible, then your car will start. If the codes aren't compatible, your vehicle won't start at all. This is why it is important to keep an extra car key, especially if the system is based on transponders. If you want to learn how to program keys, you'll require certain equipment.

This prevents unauthorised attempts to start the car because only a valid key can perform the task. This technology is believed to be more secure than conventional car keys because it makes it harder for a thief to "hot wire" an automobile and get it started.
