The keys were made of metal and had grooves to correspond to the internal parts of the ignition cylinder. However, as time progressed and technology advanced and improved, automobile manufacturers began to combine physical and electronic protocols to prevent theft. Key systems, also known as transponder keys or chips keys, are designed to make it difficult for thieves to open an automobile. The key chips in the keys have a unique serial number that transmits an electronic signal to the receiver inside of your car. When the signal is received, it compares it to an existing code in the car's computer. If the codes match, then the car will start. If not, it won't start at all. This is the reason you should keep an extra car key especially if the system is transponder-based. You'll require special equipment to learn to program keys.

The system can also identify lost or stolen cards and deactivate them. In addition, the latest models are cloud-based and permit remote management and configuration. Most modern cars are equipped with an entry system that is keyless. The system works by emitting radio signals which are picked up using a special keyfob. The signals are then compared to the code stored in the car's computer, and if all is well the car will start to unlock. If the signals don't match and the car does not start.

The chip absorbs this energy and then transmits a radiofrequency signal that contains an identification code. This code matches the unique serial numbers that are stored in the car's computers. This helps prevent unauthorised attempts to start the car, as only the correct key can start the car. The technology is believed to be more secure than traditional keys for cars because it makes it more difficult for thieves to “hot wire” a vehicle and start it.
