When you move into a house in San Fernando, buy a building, or part ways with a tenant, roommate, or employee, you rarely know how many copies of the old keys are still out there. Rekeying solves that. We alter the pin configuration inside your existing cylinders so they work with a new key, and every older key becomes useless. It is usually the most sensible way to regain control of your property, because your current locks, handles, and deadbolts stay in place.

San Fernando has a mix of buildings that makes rekeying more interesting than it sounds. The city is about 2.4 square miles, incorporated in 1911, and full of early-20th-century bungalows, craftsman and Spanish-style homes, postwar tract houses, and old brick storefronts downtown. Each of these can have different hardware, from original mortise sets to modern deadbolts from a recent remodel. Part of our job is looking at what you actually have and telling you honestly whether rekeying fits or whether something else makes more sense.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile, so there is no storefront to visit. We bring the tools and parts to your door, day or night, and do the work on site while you watch.

How it works in San Fernando

  1. 1

    Call and describe the situation

    Phone (323) 997-8867 and tell us what you have: a house, an apartment, or a storefront, how many locks need attention, and why you are rekeying. A recent move, a sale, or a lost key each shape the plan a little.

  2. 2

    We come to you

    We are 24/7 and fully mobile, so we travel to your San Fernando address with the equipment on board. Nothing needs to be dropped off, and you do not have to take your locks anywhere.

  3. 3

    Inspect each lock

    We check every cylinder: front door, back door, side gates, garage entries, and any storefront or transom-era door. Some locks, like worn or damaged cylinders, may not rekey well, and we will say so plainly before we start.

  4. 4

    Rekey the cylinders

    We remove the cylinders, replace the internal pins to match a new key cut, and reassemble. Where you want it, we can key several locks alike so one key opens your front and back doors.

  5. 5

    Test and hand over the keys

    We test each lock with the new key, confirm the old key no longer turns it, and make sure doors latch and deadbolts throw smoothly. You get your new keys and a clear understanding of what was done.

What affects the price

  • The number of locks or cylinders being rekeyed, since each one is individually disassembled and repinned.
  • The type of hardware: standard residential deadbolts differ from older mortise sets or commercial storefront cylinders.
  • Whether you want all locks keyed alike or separate keys for different doors.
  • How many extra copies of the new key you want cut.
  • Condition of the existing locks; worn or damaged cylinders may need replacement rather than rekeying.
  • Time of day and location of the call, because after-hours service is part of how a 24/7 mobile operation is priced.

Why San Fernando chooses us

  • Fully mobile service: we come to your door, with no storefront and no need to transport your hardware.
  • In business since 1987, with owner David Shar leading the work, so experience with older hardware is not guesswork.
  • Familiarity with older San Fernando building stock, including early-1900s bungalows and brick downtown storefronts with original mortise hardware.
  • Honest assessments: if a lock is too worn to rekey well, we tell you instead of selling you work you do not need.
  • Available around the clock, which matters when you discover a key problem late at night or right after a closing.
  • We work to preserve what is worth keeping, such as vintage doors, while still giving you modern key security.

Lock Rekeying across San Fernando

San Fernando sits entirely within Los Angeles County, surrounded by the City of Los Angeles, yet it runs as its own city with its own city hall and police department. It is fully reachable by road via San Fernando Road, Truman Street, Maclay Avenue, Brand Boulevard, I-5, and CA-118, so a mobile locksmith can reach any address in ZIP code 91340 without trouble.

Downtown, around the San Fernando Mall and the corner of Truman Street and San Fernando Road, many businesses occupy early-1900s brick buildings with older storefront doors and transoms. When a shop changes hands, rekeying is a practical first step so former owners and staff no longer hold working keys. Not far from Lopez Adobe and San Fernando City Hall, those older commercial locks sometimes need repair as well, and we look at that during the visit.

In the residential areas, such as the Las Palmas Park neighborhood and the streets around Layne Park and Recreation Park, you find bungalows, craftsman and Spanish homes, and postwar single-family houses. Some still carry original mortise or skeleton-key locks. If you want modern security without losing the look of a vintage door, we can talk through rekeying existing hardware or adding a modern deadbolt. Mission San Fernando Rey de España is just across the line in Mission Hills, and we serve that side too.

Lock Rekeying in San Fernando — FAQs

What does rekeying a lock actually do?
Rekeying changes the pins inside the lock cylinder so a new key operates it and the old keys no longer work. The lock hardware itself stays on your door. Call (323) 997-8867 if you want to talk through your situation.
Should I rekey after moving into a San Fernando home?
Yes, that is one of the most common reasons. You cannot know who still has copies of the previous owner's or tenant's keys. Rekeying is a straightforward way to start fresh.
Is rekeying better than replacing the locks?
Often it is, if your locks are in good condition, since you keep the hardware and only change the key. Replacement makes sense when locks are worn, damaged, or you want an upgrade.
Can you rekey the older locks in my early-1900s bungalow?
Many older mortise locks can be rekeyed or serviced, though it depends on their condition and design. We inspect them on site and tell you honestly what is possible. Skeleton-key locks may be better served by adding a modern deadbolt.
Can you rekey a storefront on the San Fernando Mall after an ownership change?
Yes. We handle older commercial and storefront hardware and can repair and rekey doors in downtown buildings. Call (323) 997-8867 to describe the doors involved.
Can I get all my doors to use the same key?
In most cases, yes. We can key compatible locks alike so one key opens the front, back, and other entries.
Do I need to bring my locks to a shop?
No. We are fully mobile and have no storefront. We do the work at your property.
Do you work nights and weekends?
We are available 24/7, including nights, weekends, and holidays, anywhere we serve in San Fernando.
