These don't sound like keys for opening doors they sound like track components to me? Or have I misunderstood.
I imagine LT is London Transport. The S is likely standard. I do not know this but it's an educated guess.

LT22 should be a key for a London Underground padlock as per this museum collection item:

S1 is what's used to start a steam engine...

When I worked for LUL S1 was thought to mean "security level 1".
How much detail do you want? You’ve previously asked this question elsewhere and if you were given any more detail than you were given there, you’d be getting details which aren’t for public knowledge.
Agreed.
You previously asked this question on another forum. Considering this appears to be content which isn't appropriate to go into too much detail into, was it really necessary to ask the same question (rather the same question and another question on a different type of key) on a different forum because you weren't given a conclusive answer in your original question?
I don't know what the forums rules are on this, but I would assume that speaking about how these keys are used/where they are used is strictly prohibited. I doubt management wants to wake up tomorrow to see that how an S1/LT22 key is or where it's used has been leaked on some railway forum.
