Car won't start

i have a 1999 honda accord. sometimes, it start, sometimes not. when it won’t start, the next day i try & it starts, have no idea for this. on the dash, it’ll show a pic that doors are open, i’ll check all the doors & they will be closed. do u have any insight on this. thank you

Take it to your local Honda mechanic and have him perform an electrical system diagnostic test.
