I like to imagine you spent more effort right-sizing the wood vs installing a door knob with a lock.

I happened to have a piece of scrap wood of the right length already. Making the hole with a hand drill took maybe 2 minutes. Don't think sourcing and installing a lock mechanism would be quicker :-)

1. Turn handle down, realizing door is locked. 2. Turn handle up to unlock door. 3. Profit.
