I'm installing a deadbolt to a steel door. There is only a sheet of metal and it is hollow (empty inside). I also need to drill the hole in the door jamb (frame of the door) so the bolt can go inside when locked.
Considering that I already drilled the 2-1/8 inches hole on both sides of the door (exterior and interior), and also the 1 inch hole for the bolt:
The inner side of the door (where bolt sleeve/plate would be attached) is flat. The bolt sleeve would not embed inside the door, and would prevent the door to fully/soft close. How to fix this? How to prepare this side of the door to embed the bolt sleeve? If it was wood, I could simply chip the wood to the required depth, but how to do it with metal/steel door (specially considering it is hollow/empty inside)?
Same question above for the door jamb. Same thing, it is flat. If I install the strike plate, it would prevent the door from closing properly. How to embed the strike plate into the door jamb?
