by "key" he's referring to a kilo

I doubt he's referring to a kilo, that amount of any substance ain't exactly for daily personal use.

I think he's literally talking about a key - getting up, using it to open the front door and start his day. Girls' always sing about leading a ghost life, giving up, sitting around doing nothing, wallowing in their pity. I think he's saying he makes the pain stop by sucking it up and going on with his day (which is, in a way, numbing it with a substance). When he sings "But if I had love, I'd throw it all away",...

it's much more literal than that, he's refering to the method of taking the substance. using a key to dip into the bag/inhale off the key is common practice.
