Will not start

Hi, I just drove my car and came home as usual, parked it and a few minutes later I wanted to go somewhere. I swing the key but it wouldn't start, I tried again and again but nothing. I then checked the fuel and sparks but there is no spark and the fuel does not go through as there is no fire. Do you have any idea why it wont start because I rely on it for daily uses, work etc? I thank you in advance. The car just will not start only it only swing if I turn the key
