This needs to be verified by a technician in person. But common items on these cars that cause this are the key cylinder, the key itself, the wiring on the steering column. Worst case could be the BCM, or body control module.
It is highly unlikely the fuses would cause such a problem. The key or key cylinder is supposed to be recognized from accessory position up to start position. Apparently it is not.
Cleaning the battery posts could help. Worth a look. Also need to make sure the battery is in good shape. Things will work, even when it is slightly under 12 volts. Even at 10 volts, like when there is a dead cell in the battery, lights and other items may still work. But will not start the engine. This is most likely an electronic problem, whether it be a battery, module, key cylinder, or wiring. Using a scanner to look at what is happening may also be helpful, but you will likely not have an advanced scanner and will need a mechanic.
