The majority of cars had basic key systems until the turn of 21st century. Keys themselves were metal and featured grooves that were connected to the internal parts of the ignition cylinder. As technology advanced the number of car makers began to combine electronic and physical protocols in order to prevent theft. Key systems like these, also known as transponder keys or chips keys are designed to make it harder for thieves to steal an automobile.

The key chips that are in the keys have a unique serial number that sends signals to the receiver inside of your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes match, then the car will start. If the codes don't match, then your vehicle won't start at all. This is one of the primary reasons why you should always keep a spare key for your vehicle, particularly when you use transponder key programming-based systems.

If you're interested in learning how to program a key, you'll need some special equipment. You'll need a blank key that is compatible with the reprogramming car key's model and make.

In addition, the latest models are cloud-based and allow for remote management and configuration.

Most modern cars come equipped with an entry system that is keyless. To make this work the car emits radio signals which are picked up by a special key fob. The signals are compared to the code stored in the computer of the car, and if all is well, the car will unlock. If the signals do not match then the car won't start. If your key fob has not been already programmed, you can follow several steps to program it.

Transponder keys, sometimes referred to as chip keys, are equipped with an embedded microchip in the head of the key. When the key is inserted into the barrel of the ignition lock and turned into the ON position, the antenna ring sends a burst of electromagnetic energy through the transponder chip. This energy is absorbed into the chip, which then transmits a radio frequency signal with an identification code that matches up to the unique digital serial number of the car's computer system. This helps prevent an unauthorized attempt to start the car as only the correct key will be able to perform the task.

This type of technology is thought to be more secure than the traditional car key, as it makes it harder for thieves to "hot wire" the vehicle to start it.
