A lock that has started to fight you is giving you a warning. The key needs a jiggle, the deadbolt only throws if you lift the door, or the latch no longer catches the strike plate. Most of the time these problems can be fixed rather than replaced, and a repair costs far less than new hardware across an entire house. That is the heart of what we do in Glendora.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on diagnosing the actual cause before touching a part. A sticking lock might be a worn cylinder, a door that has shifted, a dry mechanism, a loose mounting screw or a bent strike. Each has a different fix, and guessing wastes your money.

We are fully mobile. There is no storefront to visit; we bring our tools and a range of parts to your door, whether that is a hillside home in North Glendora, a tract house in South Glendora or a shop in Glendora Village. We work around the clock, including nights and weekends, because locks tend to fail at inconvenient times.

How it works in Glendora

  1. 1

    Call and describe the symptom

    Phone (323) 997-8867 and tell us what the lock is doing: sticking, spinning, not latching, loose on the door, or a key that will not turn. We ask about the brand, the door type and whether it is a front door, patio door or storefront, so we arrive prepared.

  2. 2

    We come to you

    Because we are fully mobile and available 24/7, a technician drives to your Glendora address with tools and common repair parts. For gated North Glendora properties, we will coordinate access details with you when you call.

  3. 3

    Diagnose before disassembling

    We test the lock with the door open and closed. This separates a failing lock from a door that has sagged, a strike plate that has drifted, or a latch rubbing the frame. Often the lock is fine and the alignment is the problem.

  4. 4

    Repair, adjust or clean

    Depending on the cause, we tighten and realign hardware, reposition strike plates, replace worn springs or cylinders, and clean and lubricate mechanisms fouled by dust and grit. Higher-end hardware gets careful handling to protect finishes.

  5. 5

    Test and explain

    We cycle the lock repeatedly with the door open and closed and check every key. We then tell you plainly what we found, and if a part is truly past saving, we explain why and what your options are before any replacement.

What affects the price

  • The root cause: a simple adjustment or cleaning differs from replacing an internal cylinder, latch or spring.
  • Hardware type and brand: standard residential deadbolts are different from high-end Baldwin or Emtek sets and multipoint patio door systems.
  • Door and frame condition: if a warped door or damaged strike plate is causing the problem, carpentry-style adjustments may be needed alongside the lock work.
  • Number of locks involved: fixing one deadbolt is a different job from addressing every lock on a house or storefront.
  • Time of day and access: after-hours calls and hard-to-reach locations such as long private drives can affect the quote.
  • Parts availability: common parts are usually on the truck, while discontinued or specialty components may need to be sourced.

Why Glendora chooses us

  • Repair-first thinking: we try to save your existing hardware before suggesting replacement, which matters most with quality sets you already paid for.
  • Fully mobile and 24/7: we come to your door at any hour, with no shop visit needed.
  • Experience since 1987: decades of work across Los Angeles County means we have seen the failures common to older and newer hardware alike.
  • Comfortable with premium hardware: we handle higher-end residential brands and multipoint systems with care for the finish and function.
  • Clear explanations: we show you what failed and why, so you can make an informed decision.
  • Owner-led standards: David Shar leads the business, and the approach stays practical and straightforward.

Lock Repair across Glendora

Glendora covers a lot of different housing, and lock problems vary with it. In North Glendora, the foothill estates and custom hillside homes are often mid-century builds with upgraded hardware, patio doors and sometimes gated drives. Heavy multipoint locks and decorative handle sets need proper alignment, and houses settle over decades, so a latch that once closed smoothly can start to bind. We handle that kind of repair at homes near the foothill trailheads and Big Dalton Canyon.

Foothill living brings its own wear. After Santa Ana wind season, homes in the fire-zone areas can end up with dust and grit in exterior locks, causing stiff keys and sluggish deadbolts. A good cleaning and lubrication, or a cylinder replacement when needed, often restores smooth operation. In South Glendora, where post-war single-family tract homes are common, we regularly see aging knobs, worn deadbolts and strike plates that have loosened over the years, particularly around Glendora Ave and Lone Hill Ave.

In Glendora Village, the historic early-1900s buildings and boutique storefronts bring older doors and frames where alignment is a frequent culprit, and a business cannot afford a door that will not lock at closing time. Whether you are in ZIP 91740 or 91741, near Citrus College, off Grand Ave, or close to the Foothill Freeway (I-210) or Route 66 along Alosta Ave and Foothill Blvd, call (323) 997-8867 and we will come to you.

Lock Repair in Glendora — FAQs

Can you repair my lock instead of replacing it?
Often, yes. Many sticking, loose or misaligned locks need adjustment, cleaning or a small part rather than full replacement. We diagnose first and only recommend replacement when repair does not make sense. Call (323) 997-8867 to describe the problem.
Why does my deadbolt only work when I lift or push the door?
That usually means the door has shifted slightly so the bolt no longer lines up with the strike plate. The fix is often realigning or repositioning the strike or adjusting hinges, not replacing the lock.
Do you repair high-end hardware on North Glendora homes?
Yes. We work on higher-end brands and multipoint patio door locks, which are common on custom foothill homes. We take care to protect finishes while repairing the mechanism.
My locks got stiff after the Santa Ana winds. What can be done?
Dust and grit can foul the inside of exterior locks. Depending on severity, we clean and lubricate the mechanism or replace a worn cylinder. Call (323) 997-8867 if keys are turning hard.
Do you come out at night or on weekends?
Yes. We are a 24/7 mobile locksmith, so you can call any hour for a lock that will not secure your home or business.
Can you fix a storefront lock in Glendora Village?
Yes. We repair storefront locks, latches and deadbolts, including those on older doors where alignment is the issue. We can also address cylinder problems if a lock is failing.
Do you have a shop I can bring my lock to?
No. We are fully mobile and do all work at your location, which also lets us check the door and frame, where many problems actually start.
How is the price of a lock repair determined?
It depends on the cause, hardware type, door condition, number of locks, time of day and parts needed. We explain what we find before work begins. Reach us at (323) 997-8867.
