ROTFL. I've posted "elevator shaft key" for a number of gadgets
(including this one), most of which I had more confidence than the
current one. It's always been wrong. A lot of people are guessng it
for this one... maybe it's finally right.
There's no such thing as a free lunch, but certain accounting practices can
result in a fully-depreciated one.
Well, for sure you "guessed right" on 286. That is what it is.
Forerunners to this type device were a crescent shaped section "rod"
without the knuckle, and so were referred to as "lunar keys", and
actuated a different door mechanism than these current types. Old
guys like me still tend to call these as "lunar keys" rather then
broken knuckle keys when we're not thinking. Technically, number 286
is a "double joint broken knuckle key", as earlier styles only have
one joint, and some that use a flat section instead of round, but they
all serve the same purpose. Of the two parallel roll-pins, the one
closest to the joints is to provide a penetration limit, and the
outside one is the finger-grip to turn the device in operation.
With very few exceptions, the doors arranged for this device are only
on the lowest level, and the lowest level plus one provided the
distance isn't over 4 feet from the car-top to the second level when
the car is a the lowest landing. Anything over the 4 feet requires a
I'd be interested to know how the OP came to have one of these, as in
Canada, Ontario in particular, they are not available to the public or
anyone outside the trade. Too easy to get hurt yourself, or injure
someone else, let alone damage something expensive if used
inappropriately or incorrectly.

need the "broken knuckle key" when a coat-hanger or other

Elevator racing using the inspection controls was fun,
not to mention the head games one could play taking over
the elevator from the top unbeknownst to the occupants.
