A lock does not always fail dramatically. Sometimes the key starts to stick, the deadbolt takes a shoulder to throw, or a latch no longer lines up after decades of settling. In Claremont, where so much of the housing is older and so much of the daily life revolves around keys, cards and shared access, replacing a lock is often the sensible, quiet fix that restores security before a real problem arrives.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no storefront to visit. Our technician brings the tools and a range of hardware to your door, looks at what you have, and helps you decide whether a replacement is truly the right move or whether a rekey or repair would serve you better. Owner and lead tech David Shar built the business on giving straight answers, and that matters in a city with as many historic doors as Claremont.

Lock replacement covers a wide range of situations: a new deadbolt after a move, a worn knob set on a rental, hardware that was damaged in a break-in attempt, a keypad or smart lock upgrade, or the quiet retirement of a lock whose keys have been handed out too many times. Whatever brought you here, we match the new hardware to your door, your habits and the level of security you want.

How it works in Claremont

  1. 1

    Call and describe the door

    Phone us at (323) 997-8867, any hour. Tell us which door it is, what the lock is doing, and whether it is a house, apartment, shop or office. Details like an older mortise lock or a keypad help us bring the right hardware.

  2. 2

    On-site inspection

    We come to you and examine the lock, strike plate, latch and door edge. A lot of sticking problems come from door alignment or a worn strike, not the lock itself, so we check before recommending anything.

  3. 3

    Choose the right hardware

    We walk through realistic options: standard deadbolts, higher-security cylinders, lever handles, keypads or smart locks. On an older door we will also tell you honestly if restoring or rekeying the existing lock makes more sense.

  4. 4

    Remove the old lock and fit the new one

    We take out the old hardware, check the bore and edge prep, and install the new lock so it throws smoothly and the bolt seats fully in the frame. If the strike or reinforcement needs attention, we address it.

  5. 5

    Test, key and hand over

    We test the lock repeatedly from both sides, confirm each key works, and show you any settings on electronic models. You leave with working keys and a clear idea of how to care for the new hardware.

What affects the price

  • The type of lock chosen, since a basic knob set, a high-security deadbolt, a mortise lock and a smart lock all differ in hardware cost and installation effort.
  • How many locks are being replaced and whether they should all be keyed alike so one key opens every door.
  • Door and frame condition, including whether the bore, latch edge or strike plate needs modification to fit the new hardware.
  • Older or specialty doors, such as period mortise setups, that may call for careful fitting or non-standard parts.
  • Time of day and urgency, since after-hours or emergency calls are handled differently from scheduled visits.
  • Whether electronic components, such as keypads or app-connected models, require setup and programming.

Why Claremont chooses us

  • Fully mobile service: we work at your door, so there is no shop trip and no leaving a property unsecured.
  • In business since 1987, which means decades of experience with both older hardware and current products.
  • Honest recommendations: if your lock only needs a rekey or repair, we say so instead of selling a replacement.
  • Owner-led operation under David Shar, with accountability that comes from a long-standing local business.
  • Available 24/7, so a broken lock or a damaged door can be dealt with when it happens.
  • Comfort with both residential doors and commercial or institutional setups, including keyed-alike and master-key arrangements.

Lock Replacement across Claremont

Claremont is an unusual mix of old and new, and lock work here reflects that. In Claremont Village, around Yale Ave and the streets nearby, many homes are Craftsman bungalows and period houses from the early 1900s through the 1920s. Their original mortise locks are often worth keeping, and owners tend to prefer careful rebuilds or rekeying over wholesale removal. When a replacement is genuinely needed, we pay attention to the door's age, thickness and trim so new hardware fits without scarring a historic entry.

The Claremont Colleges, including Pomona, Harvey Mudd, Scripps, Claremont McKenna and Pitzer, bring a different scale of need. Dorms, labs and academic buildings rely on institutional access control and master-key systems, and swapping a lock there means thinking about how it fits a larger keying plan. Off campus, student rentals and nearby homes often just need a clean change of locks between tenants. In North Claremont and the hillside Claraboya area, newer homes tend to have modern deadbolts and keypads that people want upgraded or standardized.

We serve the 91711 ZIP code and the surrounding area, reaching homes and businesses from Foothill Blvd and Indian Hill Blvd to Base Line Rd, Towne Ave and Mills Ave, with easy access from Interstate 10 and SR-210. Whether you live near the California Botanic Garden, up toward Claremont Hills Wilderness Park, or run a shop in the Village, call (323) 997-8867 and we will come to you.

Lock Replacement in Claremont — FAQs

Do you offer lock replacement in Claremont at night or on weekends?
Yes. We are available 24/7 and fully mobile, so you can call (323) 997-8867 at any hour about a damaged or failing lock in Claremont.
Should I replace or rekey my lock?
If the lock works well and you just want new keys, rekeying is often enough. Replacement makes sense when hardware is worn, damaged, outdated or you want a different security level. We will tell you honestly which fits.
Can you replace locks on a historic Craftsman home in Claremont Village?
Yes. Many older homes have original mortise locks that are worth preserving, so we often recommend rebuilding or rekeying first. If replacement is needed, we fit hardware carefully to protect the door and trim.
Can you make all my new locks work with one key?
Yes. We can install new locks keyed alike so a single key opens your front, back and other doors. Let us know when you call so we bring the right hardware.
Do you work on buildings at the Claremont Colleges?
We handle master-key and access-related lock work for institutional and commercial buildings. Call (323) 997-8867 with details about the doors and keying system so we can plan the visit.
Can you install keypad or smart locks?
Yes. We install and set up keypad and smart locks, check that the door and strike are suited to them, and show you how to manage codes or settings.
Do I need to be there during the replacement?
Someone authorized should be present so we can verify who the property belongs to, confirm which locks to change and hand over keys.
Is there a shop I can visit?
No. Crenshaw Lock Company is mobile only. We bring the tools and hardware to you anywhere in Claremont, including the Village, North Claremont and the 91711 area.
