However, as time progressed and technology improved as it did, 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 difficult for thieves to start the vehicle.
The key chips inside the keys have a specific serial number, which transmits an electronic signal to the receiver inside your car. car key programming is compared with a code in the car's computer when it is received. If the codes match then your car will start. If not, it won't start at all. This is why it is important to keep a spare car key, especially if your system is transponder-based.
You'll need special equipment to be able to program keys. You'll need a blank key that is compatible with the car's model and make. These can be purchased at a dealership or by locksmiths but you must make sure they're the right ones. If you use a key for another model, it won't work.

This stops any attempts by anyone else to start the car, as only proper keys will be able to do so.
The technology is believed to be more secure than traditional keys for cars because it makes it difficult for thieves to "hot wire" a vehicle and get it started.
