It is possible to program certain car keys by the owner, but it is recommended to speak with an expert. This will help prevent any possible damage to the computer system and also ensure that the new key is working properly.
How to Program a Key
Before the turn of the 21st century most cars used basic key systems. Keys were made from metal and had grooves to correspond to the internal parts in the ignition cylinder. As time passed and technology improved as it did, automobile manufacturers began to combine physical and electronic protocols to prevent theft. Key systems are also referred to as transponder keys or chips keys are designed to make it more difficult for thieves to steal the vehicle.
The key chips that are in the keys have a specific serial number that transmits signals to the receiver in your car. When the signal is received, it compares it to an existing code in the car's computer. If the codes match, your car will begin to start. If the codes don't match, then your vehicle won't start at all. This is one of the main reasons you should keep a spare key in your vehicle, especially if you have a transponder-based system.
If you're looking to learn how to program keys, you'll require certain equipment. You'll need a blank key that is compatible with the model and make of your car. They can be purchased from the dealership or through a locksmith, but you must make sure that they are the right ones. If you try to use a key that is from an alternative model, it will not work.
Start the process by inserting the new key into the ignition and turning it to "on". You'll need to keep the key in this position for around 10 minutes and 30 seconds. Once the time has expired you can take off your key and check if the security indicator on your dashboard has gone out. If it didn't then you'll need to do it a third time.
This method is only compatible with GM vehicles and it's not 100% secure.

It is possible to control and monitor the system from anywhere in the property. Keys and locks are not required. The system can also identify and block stolen or lost cards. The latest models also support remote management and configuration as well as are cloud-based.
The majority of modern cars are equipped with the keyless entry system. This system works by emitting radio signals which are received by a special keyfob. The signals are compared with the code stored in the computer of the car and, if all is in order, the car will unlock. If car key programing do not match then the car won't start. If your key fob isn't already programmed, you can follow a few steps to programme it.
First, you'll need to make sure that all doors are locked, with the exception of the driver's side. You'll also require the original key fob, as well as any extras you'd like to program.

It is recommended to have an expert handle this task, as they will be able to minimize the risk of data corruption and make sure 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 placed in the barrel of the ignition lock. The energy is absorbed by the chip and it transmits a radio frequency signal with an identification code that is matched up to the unique serial number of the car's computer system. This helps prevent an unauthorized attempt to start the car as only the correct key can perform the task.
This technology is believed to be more secure than conventional car keys because it makes it more difficult for thieves to "hot wire" the vehicle and get it started. It's not foolproof and thieves have found ways to evade detection and defeat the system. Therefore, even vehicles with a transponder keys aren't protected from theft.
Based on the make and model of your car, you may be capable of programming a new transponder key yourself by using a key programming device that's compatible with the car you own. The key programmer will come with a user guide that will take you step-by-step through the procedure. Once you have your key and a key programmer, follow the instructions carefully and ensure that the security light on your dashboard is turned on prior to turning your engine ON.
You can seek out an expert locksmith to assist you if you're not sure about using a key programmer or if you have a car with more advanced features, like remote head keys or intelligent keys. They will have the tools and equipment required to cut an uncut key, erase the old one from the computer in the car, and program the new key for it to function properly. This will help you save money and time and will keep your car's safety system working exactly as it should. Additionally, it's much safer than trying to do it yourself! If you use the wrong key programmer or follow unofficial instructions, the information in your car's system can be corrupted and the new key won't work.
