What's the biggest thing you need a key for?

[jayemm89]

I had a random thought the other day, what is the biggest/most expensive piece of machinery that requires a key to operate it?

I was just thinking some of the airlines I had been on were so badly run it wouldnt surprise me if the pilot couldn't find the keys to start the plane, but a quick google told me that's unlikely on a 747.

However, something suitably large or expensive must still have a key. Giant earth mover, or a super yacht perhaps? Bonus points for a picture of the key

Our trains are quite long and have keys.

I still have the keys for my work place. A 100 seat pub thats currently boarded up.

Not THE biggest but possibly most powerful; Soyuz... Sort of.

The ignition sequence for Soyuz includes inserting and turning a key. However, the key and slot are in the bunker rather than the crew capsule.

I’ve got 10 driver keys on the desk infront of me right now that would allow you to drive a train if you knew what to do

There are some fenced ranches in Australia that are bigger than most UK counties. The gates are usually open but could be secured with a fairly normal padlock.

Pity the bloke who has to check the fences.

Anna Creek Station apparently is the biggest.

Slightly bigger than Israel.

I am a maintenance engineer in a huge factory, I have a master key that opens pretty much any door in the place. Does that count?

As an aside, back when the old fashioned diesel multiple unit was a daily sight the ignition key(it didn't start the engines just turned the electrics on) would also fit my Rover P5B. I'm pretty sure both had Smiths stamped on them!

I'd like to know, too. Looks suspiciously like the key to the aforementioned chastity belt.
