Modern cars have more than just a key that will start the engine. They also come with a remote that can lock or open doors. These key fobs have to be programmed to function.
It is possible to program certain keys for cars by the owner, but it is recommended to speak with an expert. This will help avoid any damage to the computer system, and also ensure that the new key works properly.
How to program a key
Up until 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 improved, more and more car makers began to mix physical and electronic protocols to stop theft. These key systems are called transponder keys or chip keys and they're designed to make it more difficult for thieves to open the vehicle.
The key chips come with a unique serial code that transmits a message to the receiver in your car. When the signal is received it is compared to a code stored in the car's computer. If the codes are compatible, then your car will begin to start. If the codes don't match, then your car will not even start. This is one of the main reasons to keep a spare key for your car, especially if you have an electronic transponder.
You'll require special equipment to learn how to program keys. You'll need a blank key that is compatible with the car's model and make. You can purchase these at the locksmith shop or at a car dealership, but it's important to get the right ones. If you use a key for another model, it will not function.

In addition, the latest models are cloud-based, allowing for remote management and configuration.
Modern cars come with keyless entry systems. The system works by emitting radio signals which are received by a special keyfob. These signals are then compared against the correct code that is stored in the car's computer, and when everything is in order the car will be able to unlock. If the signals don't match, the car will not start. If your key fob is not already programmed, you may follow a series of steps to program it.

When the key is placed in the barrel of the ignition lock and turned into the ON position, the antenna ring sends an energy burst through the transponder chip. The chip absorbs this energy, and then sends a radio frequency signal that includes an identification code. This code matches the unique serial numbers in the computer cost of programming a car key the car. This helps prevent unauthorised attempts to start the car, because only a valid key can do so.
The technology is believed to be more secure than the traditional car key since it makes it difficult for a thief “hot wire” the vehicle and then start it. It's not foolproof and thieves have discovered ways to trick and defeat the system. Therefore, even vehicles with a transponder keys aren't protected from theft.
