Certain keys for cars can be preprogrammed by the owner, however it's best to consult with an expert. This will ensure that there is no damage to the computer system of the vehicle and ensure that the key works correctly.
How do you program a key
Most cars had basic key systems until the turn of 21st century. The keys themselves were metal and had grooves that matched the internal components of the ignition cylinder. As time passed and technology advanced and improved, automobile manufacturers began to combine electronic and physical protocols to prevent theft. Key systems like these also known as transponder keys or chips keys are designed to make it harder for thieves to start a vehicle.
The key chips contain a unique serial code that transmits a message to the receiver in your car. The signal is compared to a code in the car's computer when it is received. If the codes match, the car will start. If the codes don't match, then your vehicle won't start at all. This is one of the main reasons why you should always keep a spare key in your vehicle, especially if you have a transponder-based system.
You'll need special equipment to be able to program keys. You'll need to buy an uncut key that matches your car model and make. You can buy them at a locksmith or a car dealership, but it's important to get the right ones. If you try to use a key from another brand, it won't work.
Start the process by inserting the new key into the ignition and turning it "on". You'll need to leave the key in this position for around 10 minutes and 30 seconds. After the time has passed you can take off your key and see if the security indicator on your dashboard has gone off. If it didn't go out you'll have to repeat the process for the third time.
Keep in mind that this method can only work on GM vehicles, and it's still not foolproof. If you're looking for a secure and reliable solution go to an auto locksmith or dealer to get your car programmed using an embedded chip.

The majority of modern cars are equipped with a keyless entry system. The system works by sending radio signals that are detected by an specialized keyfob. The signals are compared with the code that is stored in the computer of the car and, if all is well, the car will unlock. The car will not start when the signals aren't the same. If your key fob has not been already programmed, it is possible to follow a few steps to program it.

The energy is absorbed by the chip and sends back a radio frequency signal with an identification code that matches up to the unique serial number in the car's computer system. This stops unauthorised attempts to start the car since only correct keys will be able.
This type of technology is thought to be more secure than a traditional car key, as it makes it harder for a thief "hot wire" the vehicle and start it. It's not foolproof and thieves have discovered ways to trick and defeat the system. Therefore, even vehicles with a transponder key are not safe from theft.
