How to program a Key
Prior to the beginning of the 21st century the majority of cars had basic key systems. Keys themselves were metal with grooves that matched the internal parts of the ignition cylinder. As technology advanced the number of car manufacturers began to combine physical and electronic protocols to avoid theft. These key systems, also known as transponder keys or chips keys, are designed to make it difficult for thieves to steal an automobile.
The key chips in the keys have a specific serial number that sends signals to the receiver inside your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes match, your car will start. If not, it won't start at all. This is one of the primary reasons to keep a spare key in your car, especially when you use an electronic transponder.
If you're interested in learning how to program keys, you'll require certain equipment. You'll need a blank key that matches your car model and make.

To begin the process, insert the new key into the ignition and turn it to the "on" position. It is necessary to keep the key in this position for approximately 10 minutes and 30 seconds. After the time has expired you can take off the key and observe if the security light on your dashboard was gone. If it didn't, you'll need to repeat the process for a third time.

They are equipped with the tools and equipment needed to connect to the diagnostics port in your vehicle and make the change.
Keyless Entry Systems
Keyless entry systems provide access to your property without the need for a physical credential. They use sensors in conjunction with an onboard computer for security. This lets you control the system and monitor its activity from any place on the property, and eliminates the need for keys or locks. The system can also identify lost or stolen cards and deactivate them. Additionally, the most recent models are cloud-based and permit remote management and configuration.
Most modern cars are equipped with a keyless entry system. To make this work the car emits radio signals that are detected by a specific key fob. 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. 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.

For example, you might be instructed to insert your new key into the ignition with all doors shut and then press an appropriate button on the fob within a very short time. The car could then respond by adjusting the door locks or emitting a sound to indicate that the key has been successfully programmed.

The antenna ring transmits electromagnetic energy to the transponder whenever the key is inserted in the barrel of the ignition lock. This energy is absorbed by the chip and it transmits a radio frequency signal with an identification code that is matched up to the unique digital serial number that is stored in the car's computer system. This will prevent any unauthorised attempts to start the car since only the right key can perform the task.
The technology is believed to be more secure than conventional car keys because it makes it much harder for a thief to "hot wire" an automobile and start it. But programming car key 's not foolproof, and thieves have discovered ways to evade and defy the system - so that even cars with transponder keys aren't immune from theft.

This is just one of the reasons why it's recommended to have at least one spare key in your possession.
The key fobs contain electronic chips that communicate via radio signals with the car's receiver. The computer in the car then compares the key's code with the one stored in its database. If the codes match the car will begin. If the codes do not match the car won't start or will remain dead.
