How to Program a Car Key
Modern cars have more than a key that can start the engine. They also come with a remote control that can lock or unlock doors. Key fobs need to be programmed in order to function.
Some car keys can be programmed by the owner himself, but it is best to speak with a professional. This will avoid any damage to the computer system of the car and will ensure that the key works properly.
How to program a key
The majority of cars had basic key systems prior to the turn of the 21st century. Keys were made of metal and had grooves to correspond to the internal parts of the ignition cylinder. As technology improved, more and more automobile makers began to combine electronic and physical protocols in order to prevent theft. Key systems also known as transponder keys or chips keys are designed to make it more difficult for thieves to steal the vehicle.
The key chips have an unique serial number that sends a message to the receiver inside your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are similar then your car will start. If not, it won't start at all. This is why it is important to keep a spare car key, particularly if your system is based on transponders.
You'll require specialized equipment to learn to program keys. You'll also need to purchase a blank key that matches your specific model and make. You can buy them at the locksmith shop or at a car dealership, but it's crucial to get the right ones. If you use a key that is for another model, 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. You'll need to leave the key in this position for approximately 10 minutes and 30 seconds. Once the time is up, you can remove the key and observe whether the security indicator on your dashboard was gone. If it didn't then you'll need to repeat the process a third time.
Keep in mind that this method will only work with GM vehicles, and it's still not completely secure.

They are equipped with the tools and equipment needed to connect to the onboard diagnostics port of your car and perform the switch.
Keyless Entry Systems

This lets you control the system and monitor activity from anywhere on the property, and eliminates the need for keys or locks. The system can also detect lost or stolen cards and then deactivate them. Additionally, the most recent models are cloud-based, allowing for remote management and configuration.
Most modern cars are equipped with an entry system that is keyless. To enable this feature the car emits radio signals that are detected by a specific key fob. The signals are then compared against the correct code stored in the car's computer, and if everything is in order, the car will unlock. The car won't start in the event that the signals are not the same. If your key fob isn't already programmed, it is possible to follow several steps to program it.
First, you'll need to ensure all the doors are locked, with the exception of the driver's side. You'll need the original key fob and any additional devices you want to program.

It's best to have a professional handle this because they will be able to reduce the risk of data corruption and make sure your keys are properly programmed.
Transponder Keys
Transponder keys are also known as chip key. They have embedded microchips inside the head of the keys. When the key is placed in the barrel of the ignition lock, and turned to the ON position the antenna ring emits an electromagnetic energy blast through the transponder chip. This energy is absorbed into the chip and it transmits a radio frequency signal with an identification code that is matched up to the unique digital serial number that is stored in the car's computer system. This prevents unauthorized attempts to start the car, since only the right key will be able to start the car.
The technology is believed to be more secure than traditional car keys because it makes it more difficult for thieves to "hot wire" an automobile and get it started. But it's not foolproof, and thieves have discovered ways to trick and defeat the system - which means that even cars equipped with transponder keys aren't safe from theft.
You may be able program a transponder key on your own with an appropriate key programmer for your car. The key programmer will come with a user guide that will guide you step-by-step through the procedure. Once you have the key and key programmer, follow the instructions carefully and ensure the security light on your dashboard is turned ON prior to turning the engine on.

This is one of the main reasons why it's a good idea to always have at least one spare key in your possession.
Key fobs are equipped with electronic chips that communicate via radio signals with the car's receiver. The computer compares the key's code with the database. If the codes match the car will begin. If the codes don't match, the car will not start or will remain dead. Fortunately, the majority of electronic keys can be repaired and programmed by an experienced auto dealer or a locksmith equipped with the proper equipment.
