Certain keys for cars can be programmed by the owner, however it is recommended to consult an expert. This will ensure that there is no damage to the computer system of the car and will ensure that the key is working correctly.
How do you program a key?
Prior to the beginning of the 21st century, the majority of cars had basic key systems. Keys were made of metal and featured grooves that correspond to the internal parts of the ignition cylinder. As technology advanced the number of car manufacturers began to combine electronic and physical protocols to avoid theft. These key systems are called transponder keys or chip keys, and they're designed to make it harder for thieves to start the vehicle.
The key chips that are in the keys have a unique serial number, which transmits signals to the receiver inside your car. The signal is compared to the car's computer 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 one of the primary reasons why you should always keep a spare key in your car, especially in the case of transponder-based systems.
If you want to learn how to program keys, you'll require some special equipment. You'll also need the blank key for your particular make and model. These can be purchased at a dealership or by a locksmith however, you must be sure they're the correct ones. If you attempt to use a key from an alternative model, it won't work.
To start the process, you need to insert the new key into the ignition and switch it to the "on" position. You'll need to keep the key in this position for around 10 minutes and 30 seconds. After the time is up, you can remove your key and check if the security indicator on your dashboard has gone off. If it didn't, you will need to do it three times.
Remember that this method can only work with GM vehicles however it isn't foolproof. If you're looking for a more secure and reliable method, you should consult a professional locksmith or the dealer to get your vehicle programmed with chip. These professionals have the necessary tools and equipment to connect to the onboard diagnostic port of your car and make the switch.
Keyless Entry Systems
Keyless entry systems allow access to your property without the need for the use of a physical ID. They make use of sensors in conjunction with an onboard computer to provide security. This allows you to control the system and monitor activity from any location on your property, and does away with the requirement for locks or keys. The system is also able to detect stolen or lost cards and then deactivate them. In addition, the latest models are cloud-based and allow for remote management and configuration.
Modern cars come with keyless entry systems. The system works by sending radio signals which are picked up using a special keyfob. These signals are then compared to the correct code stored in the car's system, and when everything is in order the car will start to unlock. If the signals don't match and the car does not start. If your key fob isn't already programmed, you may follow a series of steps to programme it.
You'll first need to make sure that all doors except the driver's door are locked. You'll need the original key fob as well as any other devices you wish to program. You can also visit your local auto parts store to see if they've got the appropriate tool for your vehicle. If none of these methods work, you'll have to check the owner's manual, or a professional locksmith.

It is possible to be instructed to insert the new key into the ignition while all doors are closed, and then press the button on the keyfob after the time frame. The car could respond by turning off the door locks or emitting an audible chime as a sign that the key was successfully programmed.

It's best to have a professional handle this, as they will be able to lower the chance of data corruption and ensure that your keys are correctly programmed.
Transponder Keys
Transponder keys, sometimes referred to as chip keys, have an embedded microchip in the head of the key. The antenna ring transmits electromagnetic energy to the transponder whenever the key is put in the barrel of the ignition lock. The chip absorbs the energy and then transmits a radio frequency signal that contains an identification code. This code is in line with the unique serial numbers that are stored in the car's computers. This prevents unauthorised attempts to start the car since only the right key will be able to do so.
This technology is thought to be more secure than a conventional car key, as it makes it difficult for a thief "hot wire" the vehicle to start it. But it's not foolproof, and thieves have discovered ways to deceive and defy the system - so that even vehicles with transponder keys aren't protected from theft.

The car's computer then compares this code on the key to the one in its database. If the codes match the car will begin. If the codes don't match, the car will not start or will remain dead.
