It is possible to pre-program some car keys by the owner, however it is best to consult a professional. This will prevent any possible damage to the car's computer system, and also ensure that the new key is working properly.
How do you program the key
Before the turn of the 21st century, most cars used basic key systems. The keys themselves were metal with grooves that corresponded to the internal parts of the ignition cylinder. As technology improved the number of car makers began to mix electronic and physical protocols to avoid theft. These key systems are called transponder keys or chip keys and are designed to make it difficult for thieves to open the vehicle.
The key chips inside the keys have a unique serial number that sends a signal to the receiver inside your car. The signal is then compared to an identifier in the computer of the car when it is received. If the codes match, then the car will start. If not, it won't start at all. This is one of the main reasons you should keep a spare key for your vehicle, particularly when you use transponder-based systems.
If you're interested in learning how to program keys, you'll need some special equipment. You'll need a blank key that matches the model and make of your car. You can purchase them from a locksmith or a car dealership, but it's important to buy the right one. If you attempt to use a key that is from another brand, it will not work.
To start the process, you need to 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 seconds. Once the time has expired you can take out your key and see if the security indicator on your dashboard has gone out. If not then you'll need to repeat the process for another time.
This method is only compatible with GM vehicles and it's not 100% secure. If you want a more secure and reliable solution then you should visit a locksmith or dealer to have the car programmed using an embedded chip. These professionals have the necessary tools and equipment to access the diagnostic port on your car's motherboard and then make the change.
Keyless Entry Systems
Keyless entry systems provide access to properties without the need for an actual credential. Security is provided by a combination between sensors and an onboard computing device. It is possible to manage and monitor the system from anywhere in the property. Keys and locks are not required. The system can also detect lost or stolen cards and disable them. In addition, the newest models are cloud-based and allow for remote management and configuration.
Modern cars come with keyless entry systems. This system works by emitting radio signals that are picked up using a special keyfob. The signals are then compared with the correct code that is stored 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. If your key fob has not been already programmed, it is possible to follow a series of steps to program it.

When the key is inserted into the barrel of the ignition lock, and then turned into the ON position the antenna ring emits an energy burst through the transponder chip. The chip absorbs this energy, and then transmits a radiofrequency signal which contains an identification number. This code is in line with the unique serial numbers of the car's computers. This helps prevent unauthorized attempts to start the car, since only the right key will be able to start the car.
This 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 get it started. It's not foolproof and thieves have found ways of tricking and defeating the system. So even cars with transponder key are not immune to theft.
