How do you program the key
Before the turn of the 21st century, most cars used basic key systems. Keys were made from metal and incorporated grooves to correspond with the internal parts of the ignition cylinder. As technology advanced, more and more automobile 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 are designed to make it more difficult for thieves to start the vehicle.
The key chips that are in the keys have a specific serial number, which transmits signals to the receiver inside of your car. The signal is then compared to a code in the car's computer when it is received. If the codes match, your car will begin. If the codes don't match, then your car won't even start. This is why it is important to keep an extra car key especially if your system is transponder-based.
You'll need special equipment to learn to program keys. You'll also need an uncut key that matches your specific model and make. You can buy them at the locksmith shop or at a car dealership, but it's essential to buy the right one. If you use a key for another model, it will not work.
Start the process by inserting the new key in the ignition and turning it "on". You will need to leave the new key in this position for about 10 minutes and 30 seconds. Once the time has expired, you can remove your key and verify that the security indicator on your dashboard has gone off. If it didn't, you will need to repeat the process a third time.
Keep in mind that this method can only work with GM vehicles but it's not foolproof. If you want a more secure and reliable option then you should visit a locksmith or a dealer to have the car programmed with an embedded chip. These professionals have the necessary tools and equipment to connect to your car's onboard diagnostics port and then make the change.
Keyless Entry Systems
Keyless entry systems allow access to property without the need for a physical credential. They make use of sensors in conjunction with an onboard computer for security. This lets you manage the system and monitor its activity from any location on your property, and removes the requirement for keys or locks. The system can also identify and deactivate lost or stolen cards. The newest models also allow remote management and configuration, and are cloud-based.
The majority of modern cars are equipped with a keyless entry system. The system works by emitting radio signals that are detected by a special keyfob. The signals are compared to the code stored in the car's computer, and if all is well, the car will unlock. The car won't start in the event that the signals are not the same. If your key fob is not already programmed, you can follow several steps to program it.
You'll first need to be sure that all doors except the driver's door are locked. Also, you'll need the original key fob, along with any additional keys you'd like to program.

This is a dangerous method and could cause data corruption in your car's computer. This should be left to a professional, who can minimize the risk of data corruption and make sure that your keys are correctly programmed.
Transponder Keys
Transponder keys are also known as chip keys. They have an embedded microchip in the head of keys. The antenna ring transmits electromagnetic energy to the transponder whenever the key is inserted into the barrel of the ignition lock. The chip absorbs this energy and then transmits a radio frequency signal that includes an identification code. The code is matched to the unique serial numbers of the computer of the car. This stops unauthorized attempts to begin the car as only the proper keys will be able to do so.
The 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 start it. It's not foolproof and thieves have discovered ways to evade detection and defeat the system. So even cars with transponder key are not immune to theft.
Depending on the brand and model of your car, you may be capable of programming a new transponder key by yourself with a key programer that is compatible with your particular car.

The key fobs have electronic chips inside them that communicate with the car's receiver using radio signals. The computer compares the code of the key with the database. If the codes match, the car will start. If not, the vehicle will not start or fail to start. Luckily, most of these electronic keys can be replaced and programmed by a professional locksmith or an auto dealer using the appropriate equipment.
If you can find a low-cost car key programer on the internet or at an auto parts store, the process will be relatively simple.
