I had same problem from new. take off strike plate and grind out the front entirely. file smooth and re-install, the door frame still stop the door from opening with dead bolt close, it is very tight the way they make it. my door also squeaks going down road. i fix most of it by adjusting the screen door, and level the main door. still does it but only once a while.
