How to program a Key
Before the turn of the 21st century the majority of cars had basic key systems. Keys were made from metal and incorporated grooves to correspond with the internal parts in the ignition cylinder. As technology advanced, more and more car manufacturers began to combine physical and electronic protocols in order to prevent theft. These key systems are referred to as transponder keys or chip keys and they're designed to make it more difficult for thieves to open the vehicle.
The key chips inside the keys have a unique serial number, which transmits an electronic signal to the receiver inside of your car. The signal is compared with a code in the car's computer when it is received. If the codes match the car will begin to begin. If the codes don't match, then your car will not even start. This is one of the main reasons why you should always keep a spare key on your vehicle, particularly when you use transponder-based systems.
You'll require special equipment to learn how to program keys. You'll also need to purchase a blank key for your specific make and model. You can buy them at an auto locksmith or a locksmith dealership, but it's important to purchase the correct keys. If you use a key from another model, it will not work.
Start by inserting the new key in the ignition and turning it "on". It is necessary to leave the new key in this position for approximately 10 minutes and 30 second. After the time has expired you can take off the key and observe whether the security indicator on your dashboard was gone. If it didn't go out, you will need to do it a third time.
Keep in mind that this method will only work on GM vehicles however it isn't completely secure.

This lets you control the system and monitor activities from anywhere within the property, and it does away with the need for locks or keys. The system can also detect and disable stolen or lost cards. The newest models also allow remote management and configuration as well as are cloud-based.
Most modern cars come equipped with the keyless entry system. The system works by emitting radio signals which are detected by an specialized keyfob. The signals are then compared with the correct code in the car's system, and when everything is in order the car will start to unlock. The car won't start when the signals aren't the same. If your key fob has not been already programmed, you may follow a few steps to programme it.

Transponder Keys
Transponder keys, also known as chip keys, come with an embedded microchip in the head of the key. The antenna ring transmits electromagnetic energy to the transponder whenever the key is placed in the barrel of the ignition lock. This energy is absorbed into the chip, which then transmits an audio frequency signal that contains an identification code that corresponds with the unique digital serial number in the car's computer system. This helps prevent unauthorised attempts to start the car, because only a valid key can do so.
This technology is believed to be more secure than traditional keys for cars because it makes it difficult for thieves to "hot wire" the vehicle and get it started. However, it's not foolproof and thieves have discovered ways to trick and thwart the system so that even cars that have transponder keys aren't protected from theft.
You could be able to program a transponder key yourself if you have an instrument that works with your vehicle. The key programmer should come with a step-by-step guide that will walk you through the process of programming your key. Follow the steps and switch on the security light on your dashboard before you start your engine.

This is just one of the reasons why it's a good idea to always have at least one spare key in your possession.
The key fobs contain electronic chips that communicate via radio signals to the car's receiver. The computer compares the key's code with the database. If the codes are the same the car will be able to start. If not, the vehicle will remain dead or refuse to start. Fortunately, the majority of electronic keys can be replaced and programmed by an experienced locksmith or an auto dealer using the appropriate equipment.
