San Fernando is a small city with an unusually wide range of doors. Within a couple of square miles you will find early-1900s bungalows with original mortise locks, Spanish and craftsman homes, postwar tract houses, and brick commercial buildings along San Fernando Road and the San Fernando Mall with storefront hardware that has outlasted several owners. Each of these calls for a different kind of replacement, and a one-size-fits-all deadbolt from a big-box shelf is often the wrong answer.

Lock replacement is different from rekeying. Rekeying changes the internal pins so old keys stop working while the existing lock stays in place. Replacement makes sense when the hardware itself is the problem: a deadbolt that sticks or spins freely, a latch that no longer lines up, a cylinder damaged after a break-in attempt, a lock that has simply worn out, or old hardware you want to upgrade for security or convenience. We will tell you honestly which of the two your door actually needs.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile, with no storefront to visit. We bring tools and hardware to you, whether that is a front door near Las Palmas Park or a shop door downtown.

How it works in San Fernando

  1. 1

    Call and describe the door

    Call (323) 997-8867 and tell us what you have: the type of door, what the lock is doing, and whether it is a house, apartment or business. Details such as an older mortise lock or a glass storefront door help us bring the right hardware.

  2. 2

    Assess the existing hardware on site

    When we arrive, we look at the lock, the door edge, the strike plate and the frame. On older doors we check for wear, previous repairs and whether the door was bored for modern hardware or is still set up for a mortise body.

  3. 3

    Recommend the right replacement

    We explain your options in plain terms, including deadbolts, knob and lever sets, mortise replacements and smart or keypad hardware. If a repair or rekey would solve the problem, we say so rather than sell you something you do not need.

  4. 4

    Install and fit the new lock

    We remove the old hardware and install the new lock so it sits square and the bolt throws smoothly into the strike. On vintage doors we work to preserve the original wood and finish wherever possible.

  5. 5

    Key setup and testing

    We cut or set keys for the new lock and, if you wish, key several locks alike so one key works for the front and back doors. We cycle the lock repeatedly with the door open and closed before we leave.

  6. 6

    Hand-off and old hardware

    We hand over all keys and explain how the lock works. If you want to keep original hardware from an older home, tell us and we will set it aside for you.

What affects the price

  • The type of lock chosen: a basic deadbolt, a higher-security cylinder, a mortise lock or an electronic keypad each come with different hardware costs.
  • How many locks are being replaced and whether they are keyed alike, since a whole-house or whole-storefront project differs from a single door.
  • The condition and age of the door and frame, as older doors may need extra fitting, new strike plates or minor adjustments to accept new hardware.
  • Whether the work is a standard installation or involves specialty hardware, such as mortise bodies or storefront locks on commercial doors.
  • The time of day and the urgency of the visit, since after-hours or emergency calls differ from scheduled work.
  • Whether you supply your own hardware or ask us to source it, including any finish matching for a vintage look.

Why San Fernando chooses us

  • Fully mobile and available 24/7, so a broken lock at night does not have to wait until morning.
  • Serving Los Angeles and Ventura County since 1987, with experience on both older mortise hardware and modern deadbolts.
  • Honest guidance on replace versus rekey versus repair, so you pay only for what the door needs.
  • Care with historic doors: we aim to modernize security without drilling up or ruining original wood on early-1900s bungalows.
  • Comfortable with both homes and commercial storefronts, including older transom-era doors downtown.
  • No storefront overhead or showroom; we come to your door with tools and hardware in the vehicle.

Lock Replacement across San Fernando

San Fernando is its own city, surrounded by the City of Los Angeles, but it is easy to reach by road. We work from San Fernando Road and Truman Street to Maclay Avenue and Brand Boulevard, with I-5 and CA-118 nearby for getting around the area. Whether you are in ZIP code 91340 or just across the city line, we serve you the same way.

Downtown, the San Fernando Mall and the blocks along San Fernando Road are lined with early-1900s brick buildings, many with older storefront doors and transoms. When a business changes hands, replacing or rekeying the lock is often the first step, since you cannot know who still holds a copy of the old key. Older mortise and storefront hardware sometimes can be repaired, and sometimes it is time for a new lock, and we will help you decide.

In residential areas such as the Las Palmas Park neighborhood and the Layne Park and Recreation Park area, many homes are early-20th-century bungalows, craftsman and Spanish houses. Some still have original mortise or skeleton-key locks. A common project is adding a modern deadbolt while keeping the vintage door intact, so the home looks as it always has but locks the way a current home should. Postwar tract homes nearby often just need a worn knob or deadbolt swapped for something sturdier.

Lock Replacement in San Fernando — FAQs

What is the difference between lock replacement and rekeying?
Rekeying changes the pins inside your existing lock so old keys no longer work. Replacement removes the lock and installs new hardware. If your lock is worn, damaged or outdated, replacement is the better choice. If it works fine and you only want new keys, rekeying may be enough. Call (323) 997-8867 and we will help you choose.
Can you replace locks at night or on weekends in San Fernando?
Yes. We are available 24/7 and fully mobile, so we come to your home or business in San Fernando at any hour. Call (323) 997-8867 and describe the situation.
My bungalow has an original skeleton-key or mortise lock. Do I have to replace the door?
Usually not. In many cases we can add a modern deadbolt or replace the mortise hardware while keeping the original door. We look at the door's thickness and condition first, and we try to preserve the vintage look while improving security.
Can you replace the lock on a downtown storefront after a change in ownership?
Yes. We work on commercial doors, including older storefront and mortise-style hardware found in early-1900s buildings along San Fernando Road and the San Fernando Mall. Depending on the lock's condition, we may replace it or rekey it so previous keys no longer work.
How do I know if my lock needs to be replaced?
Common signs include a key that sticks or breaks, a deadbolt that does not fully extend, a loose or spinning cylinder, visible damage from a break-in attempt, or a lock that is simply very old. If you are unsure, we can inspect it and give you an honest opinion.
Can you key all my new locks to the same key?
Yes, in most cases. We can set up several new locks keyed alike so one key opens your front and back doors, for example. Ask when you call (323) 997-8867 and we will plan it with you.
Do you have a shop I can visit in San Fernando?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to you, bringing what we need to complete the job at your door.
How is the price of a lock replacement determined?
It depends on the type and number of locks, the condition of your door and frame, any specialty hardware involved, and the timing of the visit. We explain the options before starting work so there are no surprises.
