Here are some common solutions that worked for our users.
- Check the bottom strike plate that goes with your door handle. If there are loose screws, tighten them to flatten the strike plate against the door frame.
- Check the strike plate and dust box area on your door frame:
- The dust box is optional and can be removed if it hinders the deadbolt from fully extending.
- Some doors have two deadbolt strike plates stacked together on the door frame. If that is your case, oftentimes the strike plate underneath is larger than the one on top. Remove the one on top and try to lock your door.
- If there is room on the door frame, and the frame is made of wood, you can use a chisel or box knife to carve out extra width or depth for the dust box and strike plate. Next, drill two new holes for the strike plate screws.
- Check the hinges on your door to make sure they are screwed and hammered in completely. Over time, loose hinges can exacerbate door jamming.
