How to Program a Key
Before the turn of the 21st century, the majority of cars had basic key systems. The keys themselves were metal and featured grooves that matched the internal parts of the ignition cylinder. As time passed and technology improved, more and more car manufacturers began blending electronic and physical protocols to protect against theft. These key systems are referred to as transponder keys or chip keys and they're designed to make it difficult for thieves to get into the vehicle.
The key chips come with unique serial codes that transmits a message to the receiver inside your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes match, then the 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 transponder-based.
If you're interested in learning how to program keys, you'll require some specific equipment. You'll need a blank key that is compatible with your car model and make. You can purchase these at a locksmith or a car dealership, but it's important to buy the right one. If you use a key for another model, it will not function.
Start the process by inserting the new key into the ignition and turning it to "on". You'll need to leave the key in this position for about 10 minutes and 30 seconds. Once the time is up you can take out the key and see if the security light on your dashboard was gone. If it didn't, you'll need to do it again for the third time.
This method is only compatible with GM vehicles, and isn't 100% secure.

The newest models also allow remote management and configuration as well as are cloud-based.
Modern automobiles are equipped with keyless entry systems. The system works by sending radio signals which are detected by an specialized keyfob. The signals are compared with the code stored in the car's computer, and if all is well, the car will unlock. If the signals don't match, the car will not start. There are several ways to program your new key fob if it's not already programmed.
First, you'll need to make sure that all doors, except the driver's door are locked. You'll also need the original key fob, along with any additional keys you want to program.

They are equipped with an embedded microchip in the head of keys. how to program a car key transmits electromagnetic energy to the transponder whenever the key is placed in the barrel of the ignition lock. The chip absorbs the energy and then transmits a radio frequency signal that contains an identification code. The code is matched to the unique serial numbers in the computer system of the car. This stops any attempts by anyone else to start the car since only right keys can be used.
This technology is thought to be more secure than the traditional car key because it makes it harder for thieves to "hot wire" the vehicle and start it. It's not foolproof, and thieves have discovered ways to evade detection and defeat the system. So even cars equipped with transponder keys aren't protected from theft.

Key fobs are equipped with electronic chips that communicate via radio signals with the car's receiver. The computer in the car then compares the code on the key to the one in its database. If the codes are the same the car will begin. If not, the vehicle will be dead or refuses to start. Luckily, most of these electronic keys can be programmed and replaced by an expert locksmith or an auto dealer using the appropriate equipment.
