How to program a key
The majority of cars had basic key systems until the turn of 21st century. The keys themselves were just metal with grooves that matched the internal parts of the ignition cylinder. As technology improved, more and more car makers began to mix electronic and physical protocols to stop theft. Key systems like these, also known as transponder keys or chips keys are designed to make it harder for thieves to open an automobile.
The key chips have unique serial codes which transmits a signal to the receiver inside your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes are similar, your car will begin to start. If not, it will not start at all. This is why it is important to keep an extra car key, especially if the system is transponder-based.
If you're interested in learning how to program keys, you'll need certain equipment. You'll also need an uncut key for your particular model and make. You can buy them at the locksmith shop or at a car dealership, but it's important to purchase the correct keys. If you use a key from another model, it won't function.
To begin the process, simply insert the new key into the ignition and turn 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 has passed you can take out your key and verify that the security indicator on your dashboard has gone off. If it didn't then you'll need to repeat the process for the third time.
Keep in mind that this method can only work with GM vehicles however it isn't foolproof. If you're looking for a safer and reliable method, you should visit a professional locksmith or the dealer to get your vehicle programmed with chip. These professionals are equipped with the tools and equipment required to connect to the onboard diagnostics port of your car and perform the switch.
Keyless Entry Systems
Keyless entry systems allow property access without requiring a physical credential. They use a combination of sensors and an onboard computer for security. This allows you to control the system and monitor activity from any location on your property, and does away with the need for keys or locks. The system can also detect and deactivate lost or stolen cards. In addition, the latest models are cloud-based and allow for remote management and configuration.
Modern automobiles are equipped with keyless entry systems. To make this work it emits radio signals that are detected by a specific key fob. The signals are then compared to the correct code in the car's system, and if everything is in order the car will start to unlock. The car won't start if the signals are not identical. If your key fob is not already programmed, it is possible to follow a series of steps to program it.
You'll first need to be sure that all doors, except the driver's door are locked. You'll need to have the original key fob along with any extras that you want to program. You could also check with your local auto parts store because they might have the right tool to program your vehicle. If these steps do not work, you'll have to consult the owner's manual or an expert locksmith.
Once you have the correct tool, follow the instructions of the manufacturer to begin changing the program of your key fob. The process is usually quick and easy. You may be instructed to put the new key in the ignition when all doors are shut and then press the button on the keyfob within a certain time period. The car could then respond by cycling the door locks or generating a chime to indicate that the key has been successfully programmed.
A lot of locksmiths have tools that let them bypass the built-in EEPROM security in your car's key fob or remote. This is a risky method and can cause corruption of the data in your car's computer.

Transponder Keys
Transponder keys are also referred as chip keys. They have a microchip embedded in the head of keys. The antenna ring transmits electromagnetic energy to the transponder when the key is inserted into the ignition lock barrel. The chip absorbs the energy and then sends a radio frequency signal which contains an identification number. The code is matched to the unique serial numbers of the computer system of the car. This is to prevent any attempts by anyone else to start the car, as only right keys can be used.

This type of technology is thought to be more secure than a conventional car key because it makes it harder for a thief "hot wire" the vehicle and then start it. However, it's not foolproof and thieves have found ways to evade and thwart the system which means that even cars equipped with transponder keys are not protected from theft.
Based on the make and model of your car You may be in a position to program a brand new transponder key yourself by using a key programming device that's compatible with the car you own. The key programmer should include an instruction manual that will guide you through the procedure of programming your key. Follow the directions and switch on the security light in your dashboard prior to beginning your engine.
You can ask an expert locksmith to assist you if you're not confident using the key programmer or you have a car with more advanced features, like remote head keys or intelligent keys. They'll have the right tools and equipment to cut the blank key, remove your old one from your computer in your car, and then program the new key to ensure that it works correctly. This will save you time and money and ensure that your car's safety system working just as it should. Plus, it's a lot more secure than doing it yourself! Utilizing the wrong key programming software or following unofficial guides can alter the information stored in the vehicle's system and result in the key not working.
Remotes

Key fobs are equipped with electronic chips that communicate via radio signals to the car's receiver. The car's computer then compares the key's code with the one stored in its database. If the codes match the car starts. If not, the car will not start or fail to start. Most of these electronic key can be programmed and replaced by a professional locksmith or auto dealer using the right equipment.
