A lock that sticks, spins loosely, or refuses to latch rarely fails at a convenient moment. In Pomona it usually happens when you are leaving for the 10 or the 60, hauling groceries up to the door, or coming home late. The good news is that many of these problems can be fixed on the spot, without replacing the whole lock. A bit of cleaning, adjusting, re-aligning or swapping a worn internal part is often all it takes.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business around being fully mobile. We do not have a shop for you to visit. We bring the tools and parts to your door, diagnose what is actually wrong, and tell you whether repair makes sense or whether replacement would serve you better.

Pomona is a good example of why local knowledge matters. Within a few miles you can find original brass mortise locks in century-old Victorians, standard cylinders in 1970s and 80s tract homes, and aluminum-storefront hardware along Holt and Garey. Each needs a different approach, and we treat them that way instead of defaulting to a one-size-fits-all deadbolt swap.

How it works in Pomona

  1. 1

    Call and describe the problem

    Call (323) 997-8867 and tell us what the lock is doing: sticking, spinning, not latching, key hard to turn, or fully jammed. Tell us the door type and roughly how old the hardware is. That helps us bring the right parts to Pomona on the first trip.

  2. 2

    On-site diagnosis

    We inspect the lock, strike plate, latch and the door itself. Many lock problems are really alignment problems caused by a sagging door, a swollen frame or a shifted strike. Finding the true cause keeps you from paying to replace a lock that was never the issue.

  3. 3

    Repair, adjust or service

    Depending on the findings, we may realign the strike, tighten or replace loose mounting hardware, clean and lubricate the mechanism, replace worn internal components, or service a mortise body. For older hardware, we prioritize keeping the original piece working when that is practical.

  4. 4

    Honest repair-or-replace advice

    If a lock is worn past the point of reliable repair, or the hardware is not secure enough for the door, we say so plainly and explain the options. You decide. We do not push replacement when a repair will do the job well.

  5. 5

    Test and hand-off

    We cycle the lock repeatedly with the door open and closed, check every key, and confirm the latch and deadbolt engage fully. If you want, we can rekey it at the same visit so old keys no longer work.

What affects the price

  • The type of lock involved: a standard residential cylinder, a deadbolt, a mortise lock, or commercial storefront hardware each call for different labor and parts.
  • Whether the problem is the lock itself or the door alignment, since fixing a strike plate or latch position differs from rebuilding internal components.
  • The age and availability of parts, especially for older or specialty hardware in historic homes where matching pieces may take extra effort to source.
  • The time of day and urgency of the call, because after-hours and emergency requests are handled differently from scheduled visits.
  • How many locks or doors are being serviced in one visit, which matters for landlords handling multiple units or businesses with several entrances.
  • Whether you add related work at the same visit, such as rekeying, new keys, or upgrading a worn deadbolt after we assess the repair.

Why Pomona chooses us

  • Fully mobile and available 24/7, so a jammed lock at night is handled at your door without any trip to a shop.
  • Experience with older hardware, including mortise locks and skeleton-key sets, so historic-home owners are not pushed toward unnecessary replacement.
  • Repair-first thinking: we diagnose before recommending parts, and we tell you when a simple adjustment will solve the issue.
  • Serving Greater Los Angeles and Ventura County since 1987 under owner and lead technician David Shar, so you are dealing with a long-running local business.
  • Able to handle multi-unit visits for landlords, rekeying or repairing several doors in one trip to keep turnover on schedule.

Lock Repair across Pomona

Pomona's housing makes lock repair a varied job. In the Lincoln Park Historic District, large Queen Anne Victorians and Craftsman homes often still carry original brass mortise locks and skeleton-key door sets. When one of those jams, the right answer is usually careful on-site mortise servicing or a period-appropriate rekey, not a modern deadbolt that changes the look of the door. Ganesha Hills' period revival homes from the 1920s to 40s can have similar aging hardware, while Phillips Ranch is mostly 1970s and 80s tract homes and newer stucco subdivisions with standard residential cylinders that respond well to quick adjustment or part replacement.

Near Cal Poly Pomona and Western University of Health Sciences, mid-century stucco apartment courts and student rentals see heavy wear and frequent tenant turnover. Landlords there often need several units repaired or rekeyed in a single mobile visit before new move-ins arrive. Downtown around the Arts Colony, the dA Center for the Arts and Antique Row on 2nd Street, brick commercial buildings and loft conversions bring their own door and latch challenges, and aluminum-storefront retail along Holt Avenue and Garey Avenue has its own hardware.

We work across Pomona's ZIP codes, including 91766, 91767, 91768 and 91769, and reach Westmont, the Fairplex area and the neighborhoods near Pomona Valley Hospital Medical Center via I-10, SR-60, SR-57 and SR-71. During LA County Fair setup, a seized padlock on a vendor container at Fairplex is the kind of urgent job we can handle on site. Call (323) 997-8867 wherever you are in town.

Lock Repair in Pomona — FAQs

Can you repair a lock instead of replacing it?
Often, yes. Sticking, loose, misaligned or worn locks can frequently be fixed with adjustment, cleaning or replacement of internal parts. We diagnose first and only recommend replacement if repair would not be reliable. Call (323) 997-8867 to describe the issue.
Do you work on old mortise locks in Lincoln Park homes?
Yes. Many Victorian and Craftsman homes in Pomona have original brass mortise locks and skeleton-key sets. We can service them on site or discuss a period-appropriate rekey, so you can keep the original character of the door.
Is lock repair available at night in Pomona?
Yes. We are 24/7 and fully mobile, so a jammed or failing lock can be addressed any time. Call (323) 997-8867 and tell us what is happening with the door.
My key turns hard or gets stuck. What causes that?
Common causes include debris or dried lubricant inside the cylinder, a worn key, worn pins, or a door that has shifted so the bolt binds in the strike. We check each of these to find the real cause before fixing anything.
Why does my deadbolt not fully extend?
Usually the door and frame have moved slightly, so the bolt no longer lines up with the strike plate hole. Seasonal changes and settling are common causes. Realigning the strike or adjusting the door often fixes it without a new lock.
Can you repair several apartment locks in one visit?
Yes. Landlords near Cal Poly Pomona and Western University often need multiple units repaired or rekeyed between tenants. We can handle multiple doors in one mobile visit. Call (323) 997-8867 to plan it.
Do you repair business and storefront locks?
Yes. We service commercial-style hardware, including aluminum-storefront doors along Holt and Garey, as well as latches and padlocks. Describe the door and lock when you call so we can bring suitable parts.
Do I need to come to a shop?
No. Crenshaw Lock Company is mobile only and has no storefront to visit. We come to your door anywhere in Pomona and handle the repair there.
