In our building, someone discovered that a 2L plastic bottle can be used to open a door from the outside. This trick has come to the rescue of numerous neighbors over the years, especially when the door accidentally shuts due to the wind or playful kids.[1]
I locked my kid in the car recently too - found out that even regular car windows are pretty hard to break.
As a latchkey kid before cell phones who often misplaced small objects, I've broken into my own houses/apartments fairly regularly. (Now I do the boring 'keep a spare key at work (which is within walking distance))'
But I think my favorite ways are using a butter knife to jimmy locks + shimmying across a balcony/ledge with a neighbor's sword to cut my way in through an otherwise inaccessible window. Removing a door by the hinges is fun.
The easiest way to break into a home depends a lot on the home itself. You're basically memorizing the house as a system and noting what the system's weak parts are.
I live on the 14th floor, so "going through a window" isn't an option. I keep a spare key hidden on my vehicle where it can't fall out but can be retrieved with some effort.
My kid got locked out while I was away. Lauched Telegram, sent my Home Assistant bot a message to open the door covers; sent new message to unlock door and turn off the alarm. Done.
Can you just say "break into a house"? Such a weird way to put it, "hack". I get it's Hacker News, were all nerds here, but some things shouldn't be nerdwashed as a "hack", this is one of them.
picked an internal door lock once. because the key was locked inside. it is remarkably easy to do; taking 5
minutes having never done it before by watching youtube and using a paperclip.

[1] Looks like a "brazilian trick" should be specific to cheapish doors ofc https://www.youtube.com/watch?v=M6Ki4Uj5LAI
Btw this is the purest use of the internet... no discussion, no politics, just people needing help and thanking the guy for the help.
