Locks do not fail all at once. A deadbolt starts to stick in cold mornings, a key needs a little jiggle, a knob wobbles, or a latch no longer catches the strike plate. In Santa Clarita, where so many homes were built in tracts from the 1970s through the 2000s, a lot of the original hardware is still on the doors. Builder-grade cylinders do their job for years, but they wear, and eventually replacement makes more sense than another repair.

Lock replacement is different from rekeying. Rekeying changes the pins inside a cylinder you already have so a new key works and old keys do not. Replacement means removing the hardware and installing new locks: deadbolts, knobsets, levers, handlesets, or keypad and smart locks. Replacement is the right call when parts are damaged or corroded, after a break-in attempt, when you want a higher-security grade, or when you simply want a different look or a keyless option.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no storefront to visit. We bring the tools and hardware to your door in Santa Clarita, assess what you have, and tell you plainly whether new locks or a simpler fix is the better choice. If a rekey will do the job, we will say so.

How it works in Santa Clarita

  1. 1

    Call and describe what you have

    Call (323) 997-8867 any hour. Tell us which doors are involved, what the locks are doing, and whether you want matching keys across the house. Photos of the hardware help, but are not required.

  2. 2

    On-site inspection

    We look at each door: the lock, the strike plate, the latch, the door edge and the frame. Sagging doors and misaligned strikes are common causes of locks that seem broken, so we check these before recommending replacement.

  3. 3

    Choose the hardware

    We go over options in plain terms: standard deadbolts, higher-grade hardware, lever handles, keypad locks, or smart locks. We consider your budget, your HOA's rules if any, and how you actually use the door.

  4. 4

    Remove the old lock and install the new one

    We remove the old hardware, check the bore holes and edge preparation, and install the new lock so it throws smoothly and fully engages the frame. If the door needs minor adjustment to work properly, we handle it.

  5. 5

    Key matching and testing

    If you want every exterior door on one key, we set the new locks to work together. We test every lock repeatedly with the door open and closed, and hand over all keys or codes.

  6. 6

    Walkthrough and old-lock disposal

    We show you how the new locks work, including any keypad codes or app settings, and can take the old hardware with us.

What affects the price

  • How many locks are being replaced, and whether they are deadbolts, knobsets, levers or handlesets.
  • The grade and brand of hardware you choose, from standard residential to heavier-duty or smart and keypad models.
  • Whether you want all locks keyed alike, which affects how the hardware is ordered and set up.
  • Door condition: a door that needs boring, alignment or strike plate work takes more time than a clean swap.
  • Time of service: after-hours and urgent calls are handled differently than scheduled daytime visits.
  • Special requirements such as HOA-approved finishes, gate hardware or commercial exit devices.

Why Santa Clarita chooses us

  • Fully mobile, so replacement is done at your door in Santa Clarita with no need to bring locks anywhere.
  • In business since 1987, led by owner and lead technician David Shar.
  • We tell you when a rekey or a small adjustment will solve the problem instead of selling new hardware.
  • We are familiar with the builder-grade Kwikset and Schlage cylinders common on Santa Clarita tract homes and can match or upgrade them.
  • We can key several new locks alike so one key works for the front door, side door and garage entry.
  • Available 24/7, including when a break-in attempt or broken lock means a door cannot be secured.

Lock Replacement across Santa Clarita

Santa Clarita's housing is dominated by master-planned suburban tracts, and that shapes the work we do. In Saugus and Plum Canyon, we often see two-story single-family homes with attached garages where the front door, a back slider and the garage entry all carry builder-grade hardware. New buyers frequently want those locks changed right away, and when a cylinder is worn or the finish is failing, replacing the set is cleaner than rekeying pieces that are already tired. In Valencia, newer developments and townhomes often call for upgrades to keypad or smart deadbolts.

Older areas such as Newhall and Old Town Newhall have a mix of vintage homes, small commercial buildings and storefronts where original hardware may be decades old and not match modern standards. In Canyon Country, many neighborhoods sit behind gates, so we also deal with pedestrian-gate locks and keypad or fob systems alongside the front door. If you live in an HOA, check finish and style rules before choosing hardware, and we can help match what is allowed.

We serve homes and businesses across ZIP codes including 91321, 91350, 91351, 91354, 91355, 91387 and 91390, and reach you whether you are off Soledad Canyon Road, near Bouquet Canyon Road, close to Valencia Boulevard or Newhall Ranch Road, or within reach of I-5 and CA-14. Our work also covers light commercial needs, such as exit-device and panic-bar repair at warehouse and industrial spaces in Valencia.

Lock Replacement in Santa Clarita — FAQs

What is the difference between lock replacement and rekeying?
Rekeying changes the internal pins so a new key works with your existing lock. Replacement installs new hardware. Rekeying suits locks in good condition; replacement suits worn, damaged or outdated ones. Call (323) 997-8867 and we can help you decide.
Can you replace locks at night or on weekends in Santa Clarita?
Yes. We are 24/7 and fully mobile, so you can call (323) 997-8867 at any hour for a damaged lock, a break-in aftermath or a door that will not secure.
Can all my new locks use the same key?
Yes. We can set the front door, back door, side entry and garage entry deadbolts to work with one key. This is popular with new homeowners in tract neighborhoods.
Should I replace or rekey the locks after buying a home?
If the existing locks work smoothly and look sound, rekeying is often enough. If they are worn, sticky, mismatched or you want an upgrade, replacement is better. We will look at what is on your doors and advise honestly.
Can you install smart or keypad locks?
Yes. We install keypad and smart deadbolts and walk you through setting codes. We also check that the door and strike are aligned so the lock performs reliably.
Do I need HOA approval to change my locks?
Many Santa Clarita HOAs have rules on exterior hardware finish or style. Check your community guidelines first. We can recommend hardware that fits typical requirements.
What affects the cost of lock replacement?
The number of locks, the hardware grade and type, whether keys are matched, the condition of the door, and the time of service. We explain these factors when you call (323) 997-8867.
Do you have a shop I can visit?
No. We are mobile only and come to your home or business anywhere we serve in Santa Clarita.
