How to Program a Car Key
Modern cars use more than a key to start the engine. They also include a remote to lock and unlock doors. These key fobs must be programmed to work.
Some car keys can be preprogrammed by the owner himself, but it's best to consult with an expert. This will help to protect against any possible damage to the car's computer system and ensure that the new key works correctly.
How do you program a key?
Most cars had basic key systems until the turn of 21st century. Keys themselves were metal and had grooves that matched the internal components of the ignition cylinder. As time went on and technology improved as it did, automobile manufacturers began to combine physical and electronic protocols to prevent theft. These key systems are called transponder keys or chip keys and are designed to make it harder for thieves to start the vehicle.
The key chips in the keys have a unique serial number, which transmits an electronic signal to the receiver in your car. The signal is then compared to a code in the car's computer when it is received. If the codes match the car will begin to start. If not, it won't start at all. This is why it is important to keep an extra car key, especially if your system is transponder-based.
You'll require specialized equipment to be able to program keys. You'll also require an uncut key for your specific make and model. You can purchase them from an auto locksmith or a locksmith dealership, but it's important to get the right ones. If you try to use a key that is from an alternative model, it will not work.
To start the process, you need to 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 around 10 minutes and 30 seconds. After the time has expired, you can remove the key and observe if the security light on your dashboard went out. If it didn't you'll have to repeat the procedure for the third time.
Remember that this method can only work with GM vehicles, and it's still not 100% secure. If you're looking for a more secure and reliable option then you should visit an auto locksmith or dealer to have your vehicle programmed with an embedded chip. These professionals are equipped with the tools and equipment needed to access the onboard diagnostics port in your car and make the change.
Keyless Entry Systems

It is possible to monitor and control the system from anywhere in the property. Keys and locks are not required. The system can also identify stolen or lost cards and disable them. Additionally, the most recent models are cloud-based and permit remote management and configuration.
Most modern cars come equipped with the keyless entry system. To accomplish this, the vehicle emits radio signals that are detected by a specific key fob. These signals are then compared to 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 and the car does not start. If your key fob is not already programmed, you can follow several steps to program it.
The first step is to make sure that all doors are locked, with the exception of the driver's side. You'll also need the original key fob and any other accessories you'd like to program.

Transponder Keys
Transponder keys, also known as chip keys, have a microchip embedded in the head of the key. When the key is inserted into the barrel of the ignition lock and turned into the ON position the antenna ring transmits a burst of electromagnetic energy through the transponder chip. The chip absorbs this energy and then transmits a radiofrequency signal that contains an identification code. The code is matched to the unique serial numbers of the car's computers. 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 conventional car keys because it makes it much harder for a thief to "hot wire" a vehicle and get it started. But it's not foolproof and thieves have found ways to evade and thwart the system so that even cars with transponder keys aren't protected from theft.
