The apartment folks rekeyed the exterior door locks this weekend. Without me noticing, even (I suppose I was gone all day Saturday...). I knew this was coming at some point; when I moved in last August I was given two keys and told that eventually my unit key would be the only one I needed. Oddly enough, when I tried the lock this evening I pulled out my unit key and tried it first, without thinking. It was only after the lock opened and I saw which key I'd used, that I was very surprised. Anyway, I can now ditch yet another key from my ring. "Guess I'll have room for a car key now."
