Guests room has 2 doors:
- One that opens inside the house, to let those already in the house move to guests room.
- One that opens to the outside of the house, to let those outside to get in.
The inside door will have a lock only on the inside. The guests side will have no key hole, since it is never locked/unlocked from there. The guests also never need to know if the door is locked, so no need for red/green indicators either.
Question: what are the options for such oneside-locked doors?
I thought of cutting a cylinder/barrel in half to eliminate the key hole on the guests side. But not sure how it works.
I also thought of using door latches, but these have no locks/keys, which might be useful to limit kids going to guests' room without parents' approval (key).
I also thought of digital locks, but they cost a lot in every aspect: initial and maintenance costs are too high, and replacement parts are too hard to find for the same lock, as they evolve a lot over time, which may require cutting doors again and again to adapt to size variations.
