    Hi,
    I have a couple of aluminium doors, one single rear door and a double porch door.

    I have been trying to find replacement locks and John D has provided me with some very useful links, but I could not find anything that will fit.

    So, I'd like to ask for some guidance on adding locks to old aluminium doors.

    The main problem I have is that, unlike wooden doors, you don't have a solid body that you can just cut out a new location for the lock to fit into. Instead the original locks have specific fixing points, of course.

    I considered bolts attached to the frame, but I need something, front and back that I can lock externally, but with the lock body internal.

    That lead me to wonder if something like these garage bolts could be repurposed as internal bolts that can be locked from the outside.

    I though I could put one top and bottom on each door. For the single door, the bolt would go into the wall, and on the double door I would have to add a keep for the bolt. They would be in these locations.

    I would have to drill three holes for each lock, two for the bolts and one for the key hole.

    Does that seem like a reasonable idea? Are there any lock that are especially designed for this? Alternatively, is there a good way to add firm fixing positions locks within the frame, so that new locks can be added?

    Any thoughts would be much appreciated.
