The keys themselves were metal and had grooves that corresponded to the internal components of the ignition cylinder. As time passed and technology improved, more and more car manufacturers began blending 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 difficult for thieves to get into the vehicle.
The key chips come with a unique serial code that sends a message to the receiver inside your car. The signal is compared to a code in the computer of the car when it is received. If the codes are similar the car will begin to begin to start. If not, it won't start at all. This is one of the primary reasons you should keep a spare key for your vehicle, especially if you have a transponder-based system.
If you want to learn how to program keys, you'll need some specific equipment. You'll also need the blank key that matches your specific make and model.

In addition, the newest models are cloud-based and allow for remote management and configuration.
Modern automobiles are equipped with keyless entry systems. The system works by emitting radio signals which are detected by an specialized keyfob. The signals are compared to the code that is stored in the car's computer, and if all is in order the car will start to unlock. The car won't start when the signals aren't the same. There are several steps you can take to program your new key fob, if it's not programmed yet.

Transponder keys, sometimes referred to as chip keys, come with a microchip embedded in the head of the key. When the key is inserted into the barrel of the ignition lock, and turned to the ON position the antenna ring emits an energy burst through the transponder chip. This energy is absorbed by the chip, which then transmits an audio frequency signal that contains an identification code that matches with the unique serial number that is stored in the car's computer system. This stops any attempts by anyone else to start the car, as only proper keys will be able to do so.
It is believed that this technology will be more secure than traditional keys for cars because it makes it harder for a thief to "hot wire" an automobile and start it. It's not foolproof, and thieves have discovered ways of tricking and defeating the system. So even cars equipped with transponder keys aren't safe from theft.

Therefore, you'll need at minimum two working key fobs for your vehicle in order to ensure that the process works. This is just one of the reasons why it's a good idea to always have at least one spare key available.
The key fobs have electronic chips in them which communicate with the car's receiver using radio signals. The computer in the car then compares the code on the key to the one stored in its database.
