Your third point is the kicker, that's why you're getting Peak Eiger as the answer. Ten years is a long time for something to survive on your keychain.
I swear by the Peaks for durability and functionality. Get an Eiger in SS and you'll be set.
They can be had in single mode, the electronics are fully potted in epoxy, simple twist for on/off, and they're built like tanks.
How often do you lose a light (your keys)?
You can get a Fenix E01, but you will be dissatisfied with the brightness, and blueish beam color.
Besides these, I wouldn't figure on one to last for more than a few years banging around with my keys.
