A tip about keys..

I keep the whole mess on a carabiner. It's further divided to several keyrings to simplify access to other stuff without having to shut vehicles off. This will come in handy if I'm ever in the forest being pursued by axe murderers or something. Beyond that, I could clip the carabiner full of keys to my belt (after removal) for a makeshift flail. On two occasions, it has been used in hauling heavy furniture up to a 3rd story balcony**. In any case, it's convenient to pull off the key I need for something and clip the rest to the corner of a pocket.

**using robust screw gate locking carabiners instead of crappy ones lends to the multi-purpose gear thing
