However, as time progressed and technology improved and improved, automobile manufacturers began to combine physical and electronic protocols to prevent theft. These key systems are known as transponder keys or chip keys and are designed to make it more difficult for thieves to start the vehicle.
The key chips contain an unique serial number that sends a message to the receiver inside your car. The signal is then compared to a code in the computer of the car when it is received. If the codes are compatible, then the car will start. If not, it won't start at all. This is why it is important to keep an extra car key, especially if the system is transponder-based.
You'll require specialized equipment to be able to program keys. You'll also need an uncut key that matches your specific model and make.

This is to prevent any attempts by anyone else to start the car since only proper keys will be able to do so.
The technology is believed to be more secure than conventional car keys because it makes it difficult for thieves to "hot wire" the vehicle and start it.
