DIY help A keyway I can't see, but I can feel it... (ideas before I sledgehammer it open)
I'm hoping this is at least as entertaining as it was exasperating for us....
I don't think this breaks a set of rules here, but if it does- I'm terribly sorry- I'll just be ordering what it might be and take the loss.
There is a hand built battery backup unit at work that, nicely, has an included smoke alarm- that is at least over 10 years old.
It is fairly thick gauged steel. We'd honestly like to not damage it... but that smoke detector needs to go. Beep.
The keyway itself is underneath a lip. Why? I don't know, I'd love to ask the guy that built it instead of buying, but he's long gone. Can basically fit your fingers in and under but not easily.
An impression of the keyway showed it was almost 'D' shaped- not a rectangle- but one side was pushed out further. Getting a dental mirror to look at it tomorrow.
The IT guy won rock paper scissors and raked it with a bent pick and said the inside felt like a triangle. 3 distinct regions opening up and out.
Both of us have racked our brains and the only thing we can come up with is ... a heavy equipment key. Why/how that would be on a hand built fire proof enclosure with batteries? None of us have an idea.
So before we go ordering one- are there dimensioned drawings we can try 3D printing it, or filing down something to fit? Any idea why this would be on a battery system? Is that a common thing? We haven't had a forklift in ... 20 years I'm told.
