It is possible to program certain keys for cars by the owner, but it is recommended to speak with a professional. This will avoid any damage to the car's computer system and ensure that the new key functions properly.
How do you program a key?
The majority of cars had basic keys systems up until the turn of 21st century. The keys were made of metal and had grooves to correspond to the internal parts of the ignition cylinder. However, as time progressed and technology advanced, more and more car manufacturers began blending physical and electronic protocols to stop theft. These key systems are referred to as transponder keys or chip keys and are designed to make it more difficult for thieves to open the vehicle.
The key chips contain a unique serial code which transmits a signal to the receiver in your car. The signal is compared with the computer of the car when it is received. If the codes match then your car will begin to start. If not, it will not start at all. This is why you should keep an extra car key especially if your system is based on transponders.
If you're looking to learn how to program keys, you'll require some specific equipment. You'll also require an uncut key for your specific model and make. You can purchase them from an auto locksmith or a locksmith dealership, but it's crucial to purchase the correct keys. If you use a key for another model, it will not function.
To begin the process, insert the new key into the ignition and switch it to the "on" position. It is necessary to leave the new key in this position for about 10 minutes and 30 second. After the time has expired you can take out the key and observe whether the security indicator on your dashboard went out. If it didn't you'll have to repeat the procedure three times.

If you're looking for a more secure and reliable method, you should consult a professional locksmith or dealer to get your vehicle programmed with chip.

Keyless Entry Systems
Keyless entry systems provide access to properties without the need for the use of a physical ID. Security is offered by sensors that are combined with an onboard computer. This lets you manage the system and monitor activities from any location within the property, and it does away with the need for locks or keys. The system can also detect and disable stolen or lost cards. Additionally, the most recent models are cloud-based and allow for remote management and configuration.
Most modern cars are equipped with an entry system that is keyless. The system works by sending radio signals that are received by the keyfob. The signals are compared with the code that is stored in the car's computer and if everything is well, the car will unlock. The car will not start if the signals are not identical. If your key fob isn't already programmed, you can follow a few steps to program it.

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, which then transmits the radio frequency signal, which includes an identification code that matches up to the unique serial number of the car's computer system. This helps prevent an unauthorized attempt to start the car, as only the correct key can perform the task.
This technology is believed to be more secure than traditional keys for cars because it makes it difficult for thieves to "hot wire" an automobile and start it. It's not foolproof and thieves have discovered ways of tricking and defeating the system. So even cars equipped with transponder keys aren't protected from theft.

If the codes match the car starts. If not, the car will not start or fail to start. Fortunately, the majority of electronic keys can be replaced and programmed by an experienced locksmith or an auto dealer equipped with the proper equipment.
The process should be relatively easy if you find a low-cost key programmer on the internet or in an auto parts store.
