How do you program the key
Prior to the beginning of the 21st century most cars used basic key systems. Keys were made from metal and featured grooves that match the internal components of the ignition cylinder. As technology improved the number of car makers began to combine electronic and physical protocols to avoid theft. These key systems are known as transponder keys or chip keys, and are designed to make it harder for thieves to start the vehicle.
The key chips have unique serial codes that sends a message to the receiver inside your car. When the signal is received it compares it with a code stored in the car's computer. If the codes match the car will begin to begin to start. If not, it won't start at all. This is why it is important to keep an extra car key, especially if your system is transponder-based.

This prevents unauthorised attempts to start the car since only right keys can be used.
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 get it started.
