Lock Installation and Deadbolt Installation in San Francisco

A new lock only works if the door, bore and strike plate all line up. Many lock problems come from a poor install: a deadbolt that has to be forced, a latch that misses the strike, or a door that has to be pulled hard to lock. This page covers mechanical, non-electrical locks.

Lock installation jobs included

  • Installing new deadbolts, including boring new holes in a door that has none
  • Replacing existing knobs, levers and entry handle sets
  • Keyed and keyless mechanical locks (push-button models that need no wiring)
  • Privacy and passage locks on interior doors
  • Strike plates adjusted, moved or reinforced with longer screws
  • Chain locks, door guards and sliding-door security bars
  • Swapping out battery-powered smart locks that fit a standard deadbolt bore

San Francisco doors and rental units

Older San Francisco homes often have thick, solid wood doors and mortise locks built into the door edge. Replacing a mortise lock with a standard deadbolt may mean filling the old pocket and boring new holes, or finding a mortise replacement that fits. Doors in older homes may also be out of square from settling, so the strike plate often needs adjusting to get a clean throw.

If you rent, California law requires landlords to provide working deadbolt locks on main swinging entry doors, and many leases limit lock changes or require giving the landlord a key. Check your lease before changing locks. Changing locks between tenants is also a standard handyman job for landlords.

What to prepare

  • Buy the lock ahead or tell us the brand and model you want
  • Measure the door thickness and the backset (edge to center of the existing hole)
  • Note whether the door is wood, metal or fiberglass
  • Keep all keys for the new lock together

When you need a locksmith or electrician

Rekeying cylinders, master-key systems, lockouts, safes and high-security locks are locksmith work. Electric strikes, access-control systems, intercom door releases and any lock that must be wired into the building need an electrician or access-control installer. For standard lock and deadbolt installation across San Francisco and the Bay Area, book 24/7 and ask about same-day appointments when a slot is open.

Lock Installation in San Francisco: common questions

Can a handyman install a deadbolt on a door without one?

Yes. Installing a deadbolt on a door without one means boring a face hole and an edge hole with a lock installation jig, mortising the latch plate, and fitting and aligning the strike in the frame so the bolt throws fully without forcing.

Do landlords in California have to provide deadbolts?

California law requires landlords to provide operable deadbolt locks on main swinging entry doors of a dwelling, along with other basic security measures. Check your lease and local rules for details on who installs and pays for lock changes.

Can you rekey my locks?

Rekeying cylinders and setting up master-key systems are locksmith jobs. A handyman can install new locks and deadbolts that come with their own keys, and adjust doors and strikes so the locks work smoothly.

Why is my deadbolt hard to lock?

A deadbolt that sticks usually does not line up with the hole in the strike plate, often because the door has sagged or the frame has shifted. Adjusting the hinges or enlarging and moving the strike typically fixes it.

Do you install smart locks?

Battery-powered smart locks that fit a standard deadbolt bore can be installed like a regular lock. Any lock or door release that must be wired into the building, like an electric strike, needs an electrician or access-control installer.
