Where’s the banana for scale? This hand is useless

This actually might be the quickest solution even if he opens the door he won’t be able to go through. I’ll look into see if there’s any gates that would work! Thank you!

My little guy is more interested in how things move and what they do when used. Like flicking light switches turning knobs, pressing buttons ect and seeing what happens when they are engaged/disengaged. Our worry is that he’ll open the door to explore to find more things to try and get lost or wander towards the river in search of more switches or nobs to turn

To be completely honest my only solution might be to rip out the door and put in a regular door so normal child locks will work. With home and safety checks we will be subjected to, having the door requiring a key on both sides won’t work and will be flagged as a danger. Thank you for your response all input has been extremely helpful including your insight

If I’m able to build a landing/porch on the outside this is the easiest solution. But at the moment my stairs make it 1.5 feet lower than the inside floor which means it’ll to high on the outside but to low on the inside.

Yes I’m in a trailer and it’s a stupid door that the Manufacturer put in to “add more natural light” if I have to stay in this trailer for more than a year I’ll take it out and put in an actual door

Yes the current lock is a simple toggle that grabs an edge of the door on the inside. There is a keyhole on the outside which pushes the lever up unlatching the clasp from the edge of the door edited spelling errors

Yes this is why I need it to be accessible on both sides of the door. 1 for emergency access and 2 so I and my partner can unlock it coming home from work if the other is sleeping edit added missing word

This is an option however Ill be moving beside a river and my child is autistic so a lock would be best if I can figure out a way to do it

I’ll look at cross posting thanks for the advice!

I like this idea and it could work well. I was considering a latch system but the issue is it would need to go at the top of the door and would be problematic on the outside with the stairs and there can be leverage at the bottom popping the door out of the tracks

Idk.. looks like he’s up to no good “ψ (｀∇´) ψ
