As time passed and technology improved as it did, automobile manufacturers began to combine physical and electronic protocols to prevent theft. These key systems are referred to as transponder keys or chip keys and they're designed to make it harder for thieves to get into the vehicle.

The key chips contain unique serial codes that transmits a message to the receiver inside your car. When the signal is received it is compared to the code that is stored in the programmable car keys's computer. If the codes are similar the car will begin to begin. If not, it won't start at all. This is one of the main reasons you should keep a spare key in your vehicle, especially when you use transponder-based systems.

You'll require specialized equipment to be able to program keys. You'll also need the blank key that matches your specific model and make.

This code matches the unique serial numbers that are stored in the computer system of the car. This prevents unauthorised attempts to start the car since only correct keys will be able.

This type of technology is thought to be more secure than the traditional car key since it makes it harder for thieves to "hot wire" the vehicle and start it.
