Keys were made from metal and featured grooves that correspond to the internal parts in the ignition cylinder. As technology advanced the number of car makers 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 harder for thieves to open an automobile.

The signal is compared to the computer of the car when it is received. If the codes are compatible, then the car will start. If not, it will not start at all. This is why you should keep a spare car key, particularly if your system is based on transponders.
You'll need special equipment to be able to program keys. You'll need to buy an uncut key that matches the model and make of your car. They can be purchased from an auto dealership or from a locksmith, but you must make sure they're the correct ones. If you try to use a key that is from another brand, it won't work.

Additionally, the most recent models are cloud-based and allow for remote management and configuration.
Most modern cars are equipped with the keyless entry system. To make this work, the vehicle emits radio signals that are detected by a specific key fob. The signals are then compared against the correct code stored in the car's computer and when everything is in order the car will start to unlock. If the signals do not match, the car will not start. There are several ways to program your new key fob, if it isn't already programmed.
First, you'll need to make sure that all doors except the driver's door are locked. You'll need the original key fob along with any additional devices you want to program.

This energy is absorbed into the chip, which then transmits the radio frequency signal, which includes an identification code that matches with the unique serial number that is stored in the car's computer system. This is to prevent unauthorized attempts to begin the car as only the proper keys will be able to do so.
This technology is thought to be more secure than the traditional car key because it makes it difficult for a thief "hot wire" the vehicle and start it. But it's not foolproof, and thieves have found ways to trick and thwart the system so that even cars that have transponder keys aren't immune from theft.
