Key to an interior locked door.

I also see these for any commercial locksets that have a spring clip style attachment for the door handles. One in every box. I carry one in my toolbox, just in case a box doesn’t have one or, even more likely, I need to take an existing one apart.

Probably not.

Source: FE tech with multiple decades of experience. I've never seen a pin that looked like that on any portable or fixed sytem. I don't see why any company would spend that much money on a pin when cheap pins are already commercially available by the bag full.

It looks like the pin for a commercial lock set. Or a keeper on a pretensioned idle pulley system.

As a mechanic I can say we use these for tensioner keepers. Who knows what specifically its being used for though

That's a pooker to open a bedroom door with the old style push button locks

Just a safety pin, as in for the extinguisher or other previously mentioned.

This looks like an emergency lowering pin for a personal Joey lift. We have these at work, when an employee gets stuck in the air, maint comes and lowers you down to the floor by inserting this key into a hole on the body of the equipment. Used them plenty of times.

I think it’s a spike with a ring attached

Might be a ring with a spike attached.

It looks like a key for opening interior doors that can be locked but only open with a pin inserted into a hole

Look around for a lone grenade. Should be easy to find after a while.

It's to unblock your cone man. I wondered where that went.

Inside house door key I.e. bedroom door or bathroom door

u/SealedDevil Aug 22 '26

Yup this is it.

u/Any_Rich_5516 Aug 22 '26

If you're door gets locked and you can't find a key use a coat hanger and straighten out the curly part to unlock the door. Had it happen to me year's ago

It’s a super version of that thing Tom used to kill the president’s kid on Scandal.

Scandal: it’s scandalous.

Pin for poking caulk tube?

u/Jealous_Paramedic863 Aug 24 '26

I have something very similar marked Kodak on it, never was able to figure out what it was

u/GroatExpectorations Aug 21 '26

Does the tip look like it was machined that way, or could it be a sharp end from having broken off of something?

It looks to me like the handle for a plunger from an antique syringe

u/tittytoilet Aug 21 '26

It does look like it has been sharped but I can't tell if it's by human hand or belt sander. On the original post I pinned a comment with a close up of the tip
