As time went on and technology improved as it did, car manufacturers began blending electronic and physical protocols to protect against theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it more difficult for thieves to get into the vehicle.

The key chips have unique serial codes that transmits a message to the receiver in your car. When the signal is received it compares it with the code that is stored in the car's computer. 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 learn to program keys. You'll need an uncut key that matches the model and make of your car. You can buy them at a locksmith or a car dealership, but it's important to buy the right one. If you use a key for another model, it will not function.

This is to prevent any attempts by anyone else to start the car since only right keys can be used.

This technology is thought to be more secure than a conventional car key because it makes it more difficult for a thief "hot wire" the vehicle and start it.
