How to Program a Car Key
Modern cars have more than just a key which will start the engine. They also come with a remote control which can be used to lock or unlock doors. These key fobs need to be programmed in order to function properly.
Certain keys for cars can be programmed by the owner themselves but it is best to speak with an expert. This will avoid any damage to the computer system of the car and ensure that the key functions correctly.
How to program the key
Before the turn of the 21st century most cars used basic key systems. The keys themselves were metal and had grooves that matched the internal components of the ignition cylinder. As technology improved the number of car makers began to mix physical and electronic protocols in order to prevent theft. These key systems are known as transponder keys or chip keys and are designed to make it harder for thieves to open the vehicle.
The key chips that are in the keys have a unique serial number that transmits an electronic signal to the receiver inside your car. When the signal is received it is compared to an existing code in the car's computer. If the codes match then your car will begin to start. If not, it won't start at all. This is one of the primary reasons you should keep a spare key in your vehicle, especially when you use an electronic transponder.
You'll need special equipment to be able to program keys. You'll need to buy a blank key that matches the model and make of your car. You can purchase them from the locksmith shop or at a car dealership, but it's essential to buy the right one. If you attempt to use a key from another model, then it won't work.
Start the process by inserting the new key into the ignition and turning it "on". It is necessary to leave the new key in this position for about 10 minutes and 30 seconds. When the time has passed you can take out the key and see whether the security indicator on your dashboard was gone. If it didn't go out, you will need to repeat the process a third time.
Be aware that this method will only work on GM vehicles, and it's still not completely secure. If you want a more reliable and secure solution, you can visit a locksmith or dealer to get your car programmed with an embedded chip. These professionals are equipped with the tools and equipment required to connect to the onboard diagnostics port in your vehicle and make the necessary changes.
Keyless Entry Systems

The system can also detect and disable stolen or lost cards. The latest models also support remote management and configuration as well as are cloud-based.
Modern cars come with keyless entry systems. To enable this feature it emits radio signals that are picked up by a specific key fob. These signals are then compared with the correct code stored in the car's computer, and when everything is in order the car will be able to unlock. If the signals do not match, the car will not start. There are several steps you can follow to program your new key fob if it's not already programmed.
You'll first need to make sure that all doors, except the driver's door are locked. Also, you'll need the original key fob and any other accessories you want to program.

For instance, you could be asked to insert your new key into the ignition while keeping all doors closed and then press the button on the key fob within a very short time. The car may then respond by turning off the door locks or emitting a chime to indicate that the key was successfully programmed.

It's best to have an expert handle this task because they will be able to lower the chance of data corruption and also ensure that your keys are correctly programmed.
Transponder Keys
Transponder keys, also referred to as chip keys, come with an embedded microchip in the head of the key. When the key is inserted into the barrel of the ignition lock and turned to ON the antenna ring emits an energy burst through the transponder chip. This energy is absorbed into the chip and it transmits a radio frequency signal with an identification code that corresponds up to the unique digital serial number that is stored in the car's computer system. This is to prevent any attempts by anyone else to start the car, as only correct keys will be able.
This technology is thought to be more secure than a conventional car key since it makes it difficult for a thief "hot wire" the vehicle to start it. It's not foolproof and thieves have found ways to evade detection and defeat the system. So even cars with transponder key are not immune to theft.
Based on the make and model of your car You may be able to program a new transponder by yourself by using a key programming device that's compatible with your specific car. The key programmer will come with a guide that will guide you step-by-step through the procedure. Once you have your key and a key programmer, follow the directions carefully and ensure the security light on your dashboard is turned ON prior to turning the engine on.

If the codes match the car will begin. If the codes do not match, the car will not start or remain dead. Fortunately, the majority of electronic keys can be programmed and replaced by an expert locksmith or an auto dealer with the right equipment.
