How do you program a key
The majority of cars had basic keys systems prior to the turn of 21st century. The keys themselves were just metal and featured grooves that matched the internal parts of the ignition cylinder. As technology improved, more and more car makers began to combine electronic and physical protocols to avoid theft. These key systems are called transponder keys or chip keys and are designed to make it harder for thieves to open the vehicle.
The key chips inside the keys have a unique serial number that sends an electronic signal 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 your car will start. If not, it won't start at all. This is why you should keep a spare car key, especially if the system is transponder-based.
If you're looking to learn how to program keys, you'll require some specific equipment. You'll need to buy a blank key that is compatible with your car model and make. These can be purchased at an auto dealership or from a locksmith however, you must be sure they're the correct ones. If you try to use a key that is from an alternative model, it will not work.
To begin the process, insert the new key into the ignition and switch it to the "on" position. You'll need to keep the key in this position for about 10 minutes and 30 seconds. After the time is up, you can remove your key and see if the security indicator on your dashboard has gone out. If not, you'll need to repeat the process for the third time.
Keep in mind that this method will only work with GM vehicles however it isn't completely secure. If you're seeking a more secure and reliable option, you should seek out an expert locksmith or dealer to get your vehicle programmed with a chip. These professionals have the tools and equipment needed to access the onboard diagnostics port in your vehicle and make the necessary changes.
Keyless Entry Systems
Keyless entry systems provide access to properties without the need for an actual credential. Security is offered by sensors that are combined with an onboard computer. This allows you to control the system and monitor activity from anywhere on the property, and does away with the need for locks or keys. The system can also identify and deactivate lost or stolen cards. The most recent models also permit remote management and configuration and are cloud-based.
Modern cars are equipped with keyless entry systems. To make this work the car emits radio signals that are picked up by a specific key fob. The signals are then compared to the code that is stored in the computer of the car, and if all is in order the car will start to unlock. If the signals don't match and the car does not start. There are several steps you can follow to program your new key fob if it's not programmed yet.
First, you'll need to ensure that all doors are locked, except for the driver's side. You'll need to have the original key fob and any extras that you want to program. You can also check the local auto parts store to see if they've got the appropriate tool for your vehicle. If none of these methods work, you'll need to check the owner's manual, or an expert locksmith.
Once you have the proper tool, you can begin the process of reprogramming your key fob following the manufacturer's instructions. The process is usually fast and simple. For instance, you could be directed to insert your new key into the ignition with the doors shut, and then press the button on the key fob within a short time frame. The car could respond by cycling doors or emitting an audible sound as a sign that the key was successfully programmed.
Many locksmiths have special tools that allow them to bypass the built-in EEPROM security on the car's key fob or remote. This is a risky technique and can cause corruption of the data in your car's computer. This is best left to a professional, who can minimize the risk of data corrupting and ensure that your keys are properly programmed.
Transponder Keys
Transponder keys, also referred to as chip keys, have an embedded microchip in the head of the key. The antenna ring transmits electromagnetic energy to the transponder when the key is put into the ignition lock barrel. The chip absorbs this energy and then transmits a radiofrequency signal which contains an identification number. This code is in line with the unique digital serial numbers that are stored in the computer system of the car. This helps prevent an unauthorized attempt to start the car because only a valid key can perform the task.
This type of technology is thought to be more secure than the traditional car key since 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 reprogramming keys for cars equipped with transponder keys aren't safe from theft.
You may be able program a transponder key yourself with a key programmer compatible with your vehicle. The key programmer will come with a manual that will take you step-by-step through the process. Once you have the key and key programmer, follow the instructions carefully and ensure that the security light on your dashboard is ON before turning your engine ON.
If you're not comfortable the use of a key programmer or if your car comes with more advanced features, such as remote head keys or smart keys, you can go to a professional locksmith for assistance. They'll have the appropriate tools and equipment to cut the blank key, remove your old one from the car's computer and then program the new one so that it functions properly. This will save your time and money, and will keep your car's security system operating exactly as it should. Additionally, it's much safer than doing it yourself. Utilizing the wrong key programming software or following unofficial instructions could cause a problem with the information stored in your car's system, resulting in the new key not functioning.

The key system is designed to avoid hot-wiring (the method of using the key of another vehicle to start the engine) and other similar methods. To ensure that this method works, you will need at least two key fobs that are working for your vehicle. This is one of the reasons why it's recommended to have at least one spare key on hand.
The key fobs contain electronic chips that communicate using radio signals with the car's receiver. The computer examines the key's code with the database. If the codes match the car will be able to start. If not, the car will remain dead or refuse to start. Luckily, most of these electronic keys can be repaired and programmed by an experienced locksmith or auto dealer equipped with the proper equipment.
If you can locate a cheap car key programmer on the internet or in an auto parts store, the procedure is fairly simple.

This will be evident by the door locks turning or a chime that sounds audible.
