Yale "security" key

[ChemicalRobot]

I don't have many keys in my collection (in fact most are on their way to selim) but here is one that I've always really liked. It's a standard Yale key with a very readable bow and the blade reads "security" on it.
Anybody have an idea of its function?

[macgng]

it says it on the key so it must be true!

I think it's for opening a lock.

I stock these blanks, only mine don't say that on them, it probably was stamped to identify the key as going to something particular. Sometimes it's easy to do that when you have a few different locks with the same type of key. Looks cool though, I would keep it!
