How do you program a key?
The majority of cars had basic key systems up until the turn of 21st century. The keys themselves were just metal with grooves that corresponded to the internal parts of the ignition cylinder. As technology improved the number of car manufacturers began to combine electronic and physical protocols in order to prevent theft. These key systems are called transponder keys or chip keys, and they're designed to make it harder for thieves to open the vehicle.
The key chips in the keys have a specific serial number, which transmits a signal to the receiver inside of your car. The signal is compared to an identifier in the computer of the car when it is received. If the codes match the car will begin to start. If the codes aren't compatible, your vehicle won't start at all. This is the reason you should keep a spare car key, especially if your system is transponder-based.
If you're looking to learn how to program keys, you'll require some specific equipment. You'll need an uncut key that matches the car's model and make. They can be purchased from the dealership or through a locksmith but you must make sure they're the right ones. If you attempt to use a key from another brand, it will not work.
Start the process by inserting the new key in the ignition and turning it to "on". It is necessary to leave the new key in this position for about 10 minutes and 30 second. Once the time is up you can take off the key and see whether the security light on your dashboard went out. If it didn't then you'll need to do it again for the third time.

If you're looking for a more secure and reliable solution, then you should consult an expert locksmith or dealer to have your car programmed with chip. These professionals are equipped with the tools and equipment needed to connect to the onboard diagnostics port in your car and make the necessary changes.
Keyless Entry Systems
Keyless entry systems allow access to properties without the requirement for a physical ID. They utilize a combination of sensors and an onboard computer to offer security.

The system can also detect and block stolen or lost cards. In addition, the latest models are cloud-based, allowing for remote management and configuration.
Most modern cars come equipped with the keyless entry system. The system works by emitting radio signals which are picked up using the keyfob. The signals are then compared against the correct code that is stored in the car's computer and if everything is in order the car will be able to unlock. The car will not start if the signals are not identical. There are a variety of steps you can take to program your new key fob, if it's not programmed yet.

Transponder Keys
Transponder keys are also known as chip key. They are equipped with a microchip embedded inside the head of the keys. When the key is inserted into the barrel of the ignition lock and turned to the ON position, the antenna ring sends a burst of electromagnetic energy through the transponder chip. The chip absorbs this energy, and then transmits a radio frequency signal which contains an identification number. This code is in line with the unique digital serial numbers of the computer of the car. This stops 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, as it makes it more difficult for thieves to "hot wire" the vehicle and start it. It's not foolproof, and thieves have discovered ways to trick and defeat the system. So even cars equipped with transponder keys aren't protected from theft.

As a result, you'll need to have at least two functioning key fobs for your vehicle in order to ensure that the process works. It is essential to have at least two spare keys available.
Key fobs are equipped with electronic chips that communicate using radio signals with the car's receiver. The computer in the car then compares the key's code to the one in its database. If the codes are the same the car will be able to start. If not, the vehicle will be dead or refuses to start. The majority of these electronic keys can be programmed and replaced by a professional locksmith or auto dealer using the proper equipment.
