The code can inform the car that it is a genuine key and prevent it from starting with a different key.

However, if you can find a dealership that has a copy of your key, they will be able to create a new one for you for only a fraction of the cost of an auto locksmith.

The key will be programmed to your car, so it will only start when you have the right code. You can also attempt to do it yourself however, it'll take a lot of time and could harm your car's electronic components.
