Most Downey homes were built when a basic knob lock and a single-cylinder deadbolt were considered plenty. Walk through the mid-century ranch tracts and you will still find original hardware that has been turned thousands of times, sticks in cold mornings, wobbles on its backplate, or opens with a key that has been copied so often nobody knows who holds one. Replacing a lock is often the simplest way to restore both smooth operation and peace of mind.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar built the business around coming to the customer. We are fully mobile, so there is no storefront to visit. We bring a range of hardware to your door, look at what is actually installed, and help you decide whether a new lock, a rekey or a combination of the two makes sense.

Replacement is not always the right answer, and we will say so when a rekey would solve your problem for less. When replacement is the better call, such as a damaged cylinder, a failed latch, a break-in attempt, or a wish to move up to a Grade-1 deadbolt or a smart lock, we install it cleanly, test it with the door closed and open, and make sure every key you receive works as it should.

How it works in Downey

  1. 1

    Tell us what is going on

    Call (323) 997-8867 any hour. Describe the doors, what the lock is doing, and what you want from the new hardware, whether that is better security, a matching set, a keypad or simply a lock that works again.

  2. 2

    We come to you

    Because we are fully mobile, a technician drives to your Downey address with hardware on board. No shop visit is needed, and you do not have to take the door off or bring the old lock anywhere.

  3. 3

    Inspect the door and existing hardware

    We check the lock, strike plate, latch bolt, door thickness, bore holes and frame condition. On older ranch-home doors, we look for loose screws, worn strikes and short strike screws that weaken even a good deadbolt.

  4. 4

    Choose the right replacement

    We go over options such as Grade-1 deadbolts, standard knobs and levers, keypad locks and smart locks, and explain the tradeoffs plainly so you can pick what fits your door and household.

  5. 5

    Install and align

    We remove the old hardware, fit the new lock, reinforce the strike if needed, and align everything so the bolt throws fully without forcing. If you want several doors to share one key, we rekey or key them alike.

  6. 6

    Test and hand over keys

    Before we leave, we operate each lock repeatedly, confirm each key works, and show you how any keypad or smart features are set up. You get working keys and a lock you can trust.

What affects the price

  • The type of lock chosen: a basic knob set, a Grade-1 deadbolt, a keypad lock and a smart lock sit in very different cost ranges.
  • How many doors are being replaced, and whether you want them keyed alike so one key opens every entry.
  • The condition of the door and frame, since damaged bore holes, worn strikes or a misaligned latch may need extra repair work.
  • Whether the job is residential or commercial, as master-key systems and multiple-cylinder retail setups take more planning.
  • The time of day or night you call, because 24/7 service outside normal hours can affect the final quote.
  • Any extra features such as high-security cylinders, restricted keyways or additional key copies.

Why Downey chooses us

  • Fully mobile, so everything happens at your door and there is no storefront trip or leaving your home unsecured.
  • In business since 1987, which means decades of experience with older door hardware like what is found in Downey's mid-century homes.
  • Honest recommendations: if a rekey does the job, we will tell you instead of selling a full replacement.
  • Owner-led operation under David Shar, with clear communication from the first call through the final test.
  • Experience across residential, commercial and automotive work, useful when a single visit involves a home, a shop and a vehicle.
  • We explain hardware grades and features in plain language so you understand what you are buying.

Lock Replacement across Downey

Downey's housing mix shapes what we see. The mid-century ranch homes and Googie-era tracts that fill much of the city, including Orange Estates, often still carry original knob locks and single deadbolts. Near Downtown Downey, 1920s homes can have older doors and mortise-style hardware that need careful fitting rather than a one-size-fits-all swap. In North Downey (90240), larger and some semi-gated custom homes frequently call for a smart lock paired with a Grade-1 deadbolt, with the other doors rekeyed to match.

Residential work is only part of it. Retailers near Stonewood Center and the Downey Landing redevelopment, on the former aerospace site, sometimes need commercial lock replacement or master-key setups after a management change so former staff no longer hold working keys. New owners of ranch homes in 90241 and 90242 often ask us to replace or rekey every lock right after closing, since nobody knows how many copies of the old keys exist.

We reach customers across the city by way of I-5, I-105 and I-605, and local routes like Firestone Blvd, Lakewood Blvd, Florence Ave, Imperial Hwy and Paramount Blvd. Whether you are near the Columbia Memorial Space Center, around the Rives Mansion neighborhood, or anywhere else in Downey, call (323) 997-8867 and we will come to you.

Lock Replacement in Downey — FAQs

Do I need a full replacement or would a rekey be enough?
If your lock works smoothly and is not damaged, a rekey changes which key fits without replacing hardware. Replacement makes sense when the lock is worn, broken, outdated or you want an upgrade. Call (323) 997-8867 and we can help you decide.
Can you upgrade my original mid-century knob lock to a deadbolt?
Yes. Many Downey ranch homes still have original knob-only entry hardware. We can add or upgrade to a Grade-1 deadbolt, check the strike and frame, and make the door noticeably more resistant to forced entry.
Do you install smart locks and keypads?
Yes. We install keypad and smart locks, and are happy to pair them with a solid deadbolt. This is a popular choice for larger North Downey homes. We will walk you through setup before we leave.
Can all my doors use the same key after replacement?
Usually, yes. We can key new locks alike or rekey existing ones to match, so one key opens the front, back and side doors. Tell us how many doors you have when you call (323) 997-8867.
Do you work on commercial locks near Downey Landing or Stonewood Center?
Yes. We handle commercial lock replacement, rekeying and master-key setups for retailers and offices, including after a management change when old keys need to stop working.
Are you available at night or on weekends?
We are available 24/7 and fully mobile. If a lock fails or a break-in damages your door after hours, call us and we will arrange service.
I just bought a house in Downey. Should I replace the locks?
It is a smart move. You cannot know who has copies of the old keys. Depending on the hardware's condition, we can rekey or replace the locks so only the keys you hold work.
Do I need to be home during the replacement?
Someone should be present, or we should coordinate access, so we can confirm the work and hand over keys. We test every lock before finishing so you know it operates correctly.
