What's wrong with my truck

Could be a dead battery, or the battery connections need cleaning. Check the battery connections.

Thanks but i just put a new battery and clean the terminals too but nothing happens and the alarm won't go off

Any power anywhere? Head lights, radio? And did this happen after replacing the battery? I'm thinking the security system may need to be reset.

I have power in doors head lights too just the dashboard when u turn the key on some lights have to come on but no lights at all. like check engine seat belt but i get nothing just that little noise when u put the key that it
