Your door, opened and then made right.

Getting you back in is twenty minutes of work. The more useful conversation is the one after: whether the lock that just failed you was ever any good.

The California number worth knowing

California Civil Code section 1941.3 requires a landlord to fit a deadbolt on a rental's main entry with a throw of at least thirteen-sixteenths of an inch, plus working locks on windows and a locking mechanism on other exterior doors.

Thirteen-sixteenths. Not one inch. The one-inch figure is repeated everywhere and it is wrong as a statement of state law.

It is right in several cities on this Peninsula, because they adopted stricter codes of their own. The city pages say which rule applies where you are.

There is also a carve-out people miss. The state deadbolt duty does not apply to a building designated as a historical structure. In San Francisco, with hundreds of landmarked buildings, that is not hypothetical.

California Civil Code §1941.3, read via a secondary publisher. The State's own site was unreachable at the time of writing, so check the official text before relying on the wording.

Words you will hear

DeadboltA bolt you throw with a key or thumbturn. No spring. The lock that actually holds.
LatchThe sprung, angled bolt that clicks shut on its own. Not a security device.
BacksetEdge of the door to the center of the hole. Almost always 2⅜ or 2¾ inches.
Strike plateThe metal plate on the frame. With long screws into the stud, the cheapest upgrade there is.

Before you buy a lock online

Measure the backset and the door thickness first. A lock for the wrong backset will not fit, and smart locks have real limits on door thickness.
