Six things worth knowing about a door that reads a fob, a few minutes each.
What opens the lobby when the reader has gone dark, why the little cylinder under the panel will not turn after ten years, what actually happens to a credential when a resident moves out, how the four doors between the sidewalk and the apartment differ for a locksmith, which keys to sort out in the first month in a house on the old streets, and what a Castro Street shop door is really asked to do. Written for these streets and no others.

A Castro Street Storefront: What Is on the Door and What Is Asked of It
Closing time on a narrow shop front: a glass door in an aluminum frame, a brass push bar worn pale in one spot, a closer arm overhead, chairs stacked inside. Four pieces of hardware, each doing a different job, and one of them takes almost all the punishment.

An empty kitchen in a house from the thirties or fifties, late afternoon light on bare floors, and a ring of eleven mismatched keys on the counter. Nobody can tell you what four of them open. Four weeks in order, what each step costs, and what is worth leaving alone.

Four Doors Between the Street and the Apartment, and How Each Differs for a Locksmith
From the sidewalk you can see three of them at once through the glass: the lobby leaf, the inner door behind it, and the ramp down to the vehicle gate off to one side. The fourth is upstairs. Four locks, four different ways to be stuck outside, four different jobs.

A Resident Moves Out: Credentials Are Revoked, Not Re-Cut
On move-out day the counter holds two fobs, a garage remote, a small flat key on a paper tag and a printed checklist. Nothing on that counter gets re-cut. Most of it gets switched off in a list somebody else keeps, and a short part of it is still metal and still ours.

The Mechanical Key Under the Panel, and Why It Will Not Turn After Ten Years
Behind a small cover plate beside the reader sits a plain brass cylinder. It is the way in when the electronics stop, and on most buildings nobody has turned it since the day the doors were hung. What ten years without a turn do to a lock, and what it takes to put one back in service.

The Reader Has Gone Dark: What Opens the Door When the Electronics Do Not
The fob is fine. The plate beside the lobby door has no light in it, and the building is standing on the sidewalk. What actually failed, why the door still lets people out but not in, where the metal way in is hiding, and which call to make first.

Say what the door reads, and the rest of the call is short
Mountain View and the mid-Peninsula, at any hour. A fob, a card, a code or a plain key, and how many doors stand between the sidewalk and you — that decides the work, and the work decides the number. The number comes back on the same call with the $89 call-out and the clock already inside it, and it is the number on the receipt. The labor carries 90 days, in writing.
