Most cars had basic key systems up until the turn of 21st century. The keys themselves were metal and featured grooves that matched the internal parts of the ignition cylinder. As time went on and technology advanced and improved, automobile manufacturers began to combine physical and electronic protocols to stop theft. Key systems like these also known as transponder keys or chips keys are designed to make it more difficult for thieves to steal a vehicle. The key chips contain unique serial codes that sends a message to the receiver in your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are identical then your car will begin. If the codes don't match, your vehicle won't start at all. This is one of the primary reasons to keep a spare key on your vehicle, especially if you have transponder-based systems. You'll require specialized equipment to learn how to program keys.

The most recent models also permit remote management and configuration, and are cloud-based. The majority of modern cars are equipped with an entry system that is keyless. To enable this feature, the vehicle emits radio signals which are picked up by a specific key fob. The signals are compared with the code that is stored in the car's computer and if everything is well the car will start to unlock. If the signals don't match then the car won't start.

This helps prevent unauthorised attempts to start the car, since only the right key will be able to do so. This technology is believed to be more secure than traditional keys for cars because it makes it harder for a thief to “hot wire” an automobile and get it started.
