Locks wear out quietly. A deadbolt that needs a shoulder-push to throw, a knob that spins freely, a key that has to be wiggled just right: these are signs that the hardware is near the end of its life, and that a lockout or a failed break-in resistance test may be coming. Lock replacement is the planned fix, and in Pomona it rarely looks the same twice, because the city's housing spans well over a century of construction.

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 drives to you with hardware and tools, looks at the door in person, and replaces the lock right there. That matters in a city where one job might be a 1900s Craftsman front door and the next a stucco apartment unit with a standard cylinder.

Replacement is not always the right answer, and we will say so. A period mortise lock in a historic home can often be serviced or rekeyed instead of ripped out. A lock that is simply compromised because an old tenant still has a key may only need rekeying. We look at what you actually have, explain the options plainly, and then do the work you choose, whether that is a full swap, a repair, or a rekey. Call (323) 997-8867 any hour.

How it works in Pomona

  1. 1

    Call and describe the door

    Tell us what is happening: a sticking deadbolt, a broken knob, a lost key set, a tenant turnover. Tell us the kind of property, such as a Victorian, a tract home, an apartment unit, or a storefront. That lets us bring the right hardware on the first trip.

  2. 2

    On-site assessment

    We examine the door, the strike plate, the latch, and the existing lock. We check whether the door is square and the bore holes fit modern hardware. Sometimes the problem is the door or frame and not the lock, and we will tell you before replacing anything.

  3. 3

    Choose the hardware

    We walk through options: standard deadbolts, handlesets, smart or keypad locks, or period-appropriate hardware for older homes. We explain differences in security grade, finish, and how the lock works day to day, so the decision is yours.

  4. 4

    Remove and install

    The old lock comes out and the new one goes in, with the latch, strike, and bolt aligned so it throws smoothly. On older doors we take care with original wood and finishes, and where a mortise lock can be saved we discuss servicing it instead.

  5. 5

    Key setup and testing

    We cut or set keys, and can key several locks alike so one key works your front and back doors. We test every function with the door open and closed, and confirm that the bolt fully engages the frame.

  6. 6

    Walkthrough and handoff

    Before we leave, we show you how the new lock operates, hand over all keys, and mention anything worth watching, like a loose frame or worn weatherstripping that could affect the lock over time.

What affects the price

  • The type of lock: a basic cylinder deadbolt, a high-security grade, a smart or keypad model, and a specialty mortise set all differ in hardware cost.
  • The number of locks being replaced in one visit, since multi-door or multi-unit jobs spread the travel and setup across more work.
  • Door and frame condition: a door that needs boring, reinforcing, or strike plate repair takes more time than a clean like-for-like swap.
  • Whether locks need to be keyed alike or to a master system, which adds key cutting and pinning work.
  • Age and rarity of existing hardware, such as original mortise locks where parts or servicing take specialized skill.
  • The time of day and the urgency of the call, since after-hours and emergency visits differ from scheduled daytime work.

Why Pomona chooses us

  • Fully mobile service: we bring the shop to your door, so replacement happens in one visit without you driving anywhere.
  • Operating since 1987, with owner and lead technician David Shar bringing decades of hands-on experience to older and unusual hardware.
  • Open 24/7, so a broken lock after a late move-in or an attempted break-in does not have to wait until morning.
  • Honest recommendations: if rekeying or servicing will do the job, we say so instead of selling a full replacement.
  • Comfort with both historic and modern hardware, from original brass mortise sets to current tract-home cylinders and electronic locks.
  • Multi-unit capability for landlords and property managers who need several doors handled in a single mobile visit.

Lock Replacement across Pomona

Pomona's housing tells the story of the city. In the Lincoln Park Historic District, large Queen Anne Victorians and Craftsman homes often still carry original mortise locks and skeleton-key sets that predate modern deadbolts. When one of those jams, the right move is often on-site mortise servicing or a period-appropriate rekey, not a bolt-on replacement that drills out historic wood. Ganesha Hills has period revival homes from the 1920s to 1940s with their own mix of aging hardware, while Phillips Ranch is mostly 1970s and 80s tract homes and newer stucco subdivisions where standard cylinders are easy to swap.

Near Cal Poly Pomona and Western University of Health Sciences, student rentals and mid-century stucco apartment courts turn over tenants often. Landlords in ZIP codes like 91768 and 91767 frequently call us to replace or rekey several units in one trip before move-in day, which saves repeated visits. Downtown near the Arts Colony, brick commercial buildings and loft conversions bring a different mix, from aluminum-storefront doors along Holt Avenue and Garey Avenue to residential-style lofts above street level.

We also handle the unexpected. During LA County Fair setup at Fairplex, a vendor's seized padlock on a storage container can need emergency cutting and replacement on site. Whether you are in Westmont, near Pomona Valley Hospital Medical Center, or off the I-10, SR-60, SR-57, or SR-71, we are a phone call away at (323) 997-8867, including ZIPs 91766 and 91769.

Lock Replacement in Pomona — FAQs

Do I need a full lock replacement, or can my lock just be rekeyed?
If the lock still works smoothly and is in good shape, rekeying changes the key without new hardware and is often enough after a tenant change or lost key. If the lock is worn, damaged, or outdated, replacement makes more sense. Call (323) 997-8867 and we will help you decide.
Can you replace the original mortise lock on my Lincoln Park Victorian?
Often we can service or rekey an original mortise lock so you keep the period look. If the lock is beyond saving, we can discuss replacement hardware suited to the door. We assess it in person before recommending anything.
Do you come out at night or on weekends in Pomona?
Yes. Crenshaw Lock Company is available 24/7 and fully mobile, so you can call at any hour. Reach us at (323) 997-8867 and we will take it from there.
Can you replace locks on several apartment units at once?
Yes. Landlords near Cal Poly Pomona and Western University often have us replace or rekey multiple units in one visit before new tenants arrive. We can key units individually or alike, depending on how you manage the property.
Is there a shop I can visit?
No, we are mobile only. Our technician comes to your home, rental, or business with the hardware and tools needed to do the work on site.
Can you help if a padlock seizes on a storage container at Fairplex?
Yes. We can cut a seized padlock on site and fit a replacement, which is useful during LA County Fair setup when time is short. Call (323) 997-8867 to arrange it.
Can you install smart or keypad locks?
Yes, we can install keypad and smart locks as well as traditional deadbolts. We will check that your door and frame suit the hardware and explain how it works before we finish.
How is the price of a lock replacement determined?
It depends on the lock type, how many locks are involved, the condition of the door and frame, any keying requirements, and the time of the visit. We explain the factors for your situation before work begins.
