How to program a key
Most cars had basic key systems until the turn of 21st century. Keys themselves were metal and featured grooves that corresponded to the internal parts of the ignition cylinder. As technology improved, more and more car makers began to combine physical and electronic protocols in order to prevent theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it more difficult for thieves to start the vehicle.
The key chips inside the keys have a unique serial number, which transmits an electronic signal to the receiver inside your car. When the signal is received it compares it with a code stored in the car's computer. If the codes match then your car will begin. If the codes aren't compatible, your car won't even start. This is one of the primary reasons to keep a spare key for your vehicle, particularly if you have a transponder-based system.

This allows you to control the system and monitor its activity from anywhere within the property, and eliminates the requirement for locks or keys. The system can also detect stolen or lost cards and disable them. Additionally, the most recent models are cloud-based and permit remote management and configuration.
Modern cars come with keyless entry systems. To make this work the car emits radio signals that are detected by a particular key fob. These signals are then compared to the correct code in the car's system, and if everything is in order the car will be able to unlock. If the signals do not match then the car won't start. There are several steps you can take to program your new key fob, if it's not programmed yet.

The antenna ring transmits electromagnetic energy to the transponder when the key is inserted into the ignition lock barrel. The chip absorbs this energy and then sends a radio frequency signal that contains an identification code. The code is matched to the unique digital serial numbers in the computer of the car. This will prevent any unauthorized attempts to start the car, as only the correct key can do so.
This 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 get it started. It's not foolproof, and thieves have found ways to trick and defeat the system. So even cars equipped with transponder key are not immune to theft.
