Re: Deadbolt installation in basement door
If I'm reading you properly, the issue is that the strike screws won't have purchase.
Depending on the amount of security you need, you could install a security strike plate, which is much longer and should allow better anchoring into the concrete with at least two of the screws. If you want more than that, then I would suggest installing something along the lines of a 1x on the face of the wall next to the door jamb with a metal strap over the top of it. This will beef up the strike region quite well and give a place for the strike screws to have purchase.
Keep in mind that no matter what you do to the door, it's only going to keep the honest people out.
