Installed the early birthday present from my sister: a new lock for the back door. I'm having the porch deck out front redone so at the moment that door isn't practically usable, but getting home from work last night I discovered that the outside of the back door lock which worked well enough to lock the door on my way out no longer unlocked from that side (inside still worked). Needed to find a ladder to climb up to the front door to get in last night and would rather not repeat that.
