How to Program a Car Key
Modern cars have more than just a single key to start the engine. They also come with a remote that can lock and unlock doors. These key fobs have to be programmed to function.
It is possible to pre-program certain car keys by the owner, however it is recommended to speak with an expert. This will ensure that there is no damage to the computer system of the vehicle and ensure that the key functions properly.
How to Program a Key
Before the turn of the 21st century, most cars used basic key systems. Keys themselves were metal and featured grooves that corresponded to the internal components of the ignition cylinder. As technology advanced, more and more car makers began to mix physical and electronic protocols in order to prevent theft. Key systems, also known as transponder keys or chips keys, are designed to make it difficult for thieves to steal an automobile.
The key chips have an unique serial number that sends a message to the receiver inside your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes match the car will begin to start. If not, it won't start at all. This is the reason you should keep an extra car key, especially if the system is transponder-based.
If you're looking to learn how to program keys, you'll require certain equipment. You'll also need to purchase a blank key for your specific model and make. These can be purchased at a dealership or by locksmiths, but you must make sure that they are the right ones. If you try to use a key that is from another brand, it will not work.
To start the process, you need to 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 expired you can take off the key and see whether the security indicator on your dashboard went out. If it did not, you will need to do it for the third time.

These professionals have the tools and equipment needed to access the onboard diagnostics port in your car and make the necessary changes.
Keyless Entry Systems

Additionally, the most recent models are cloud-based and permit remote management and configuration.
Modern cars are equipped with keyless entry systems. This system works by emitting radio signals which are detected by an specialized keyfob. The signals are then compared to the correct code stored in the car's computer, and if everything is in order, the car will unlock. If the signals do not match then the car won't start. There are a variety of steps you can follow to program your new key fob, if it isn't already programmed.

The car could then respond by adjusting the door locks or emitting a sound to signal that the key was successfully programmed.
A lot of locksmiths utilize special tools to get around the EEPROM security that is built into your car's remote or key fob.

Transponder Keys

Transponder keys are also known as chip key. They feature an embedded microchip inside the head of the keys. When the key is placed in the barrel of the ignition lock, and turned into the ON position the antenna ring transmits an electromagnetic energy blast through the transponder chip. The chip absorbs the energy and then sends a radio frequency signal which contains an identification number. This code matches the unique serial numbers that are stored in the computer system of the car. This prevents an unauthorized attempt to start the car since only the right key will be able to start the car.
The technology is believed to be more secure than traditional car keys because it makes it difficult for thieves to "hot wire" a vehicle and get it started. It's not foolproof and thieves have discovered ways to evade detection and defeat the system. Therefore, even vehicles with a transponder keys aren't immune to theft.

This will help you save money and time and ensure that your car's safety system operating just as it should. Additionally, it's much safer than making it yourself.
