Rekeying changes the inner workings of a lock so that a new key operates it and every previous key becomes useless. The lock itself stays on the door. You keep the hardware you already like, and you end the question of who might still be holding a copy. It is usually the sensible first step after buying a home, ending a tenancy, a breakup, a lost key ring, or a departing employee.

Pomona is a good example of why rekeying should be matched to the building. A Queen Anne Victorian in the Lincoln Park Historic District might have an original brass mortise lock. A 1970s tract home in Phillips Ranch likely has standard residential cylinders. A student rental near Cal Poly Pomona may have several units that all need new keys before the next lease starts. Each of these calls for a different approach, and we plan for that.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile. There is no storefront to visit, because the work happens at your door, whenever you need it, day or night.

How it works in Pomona

  1. 1

    Tell us about the property

    When you call (323) 997-8867, we ask what kind of locks are involved, how many doors, and what prompted the change. A single front door after a home purchase is different from a block of apartment units, and a few questions up front help us bring the right tools and parts.

  2. 2

    We come to you

    Because we are fully mobile and available around the clock, we travel to your address in Pomona with the equipment on board. There is nothing to drop off and no shop to visit, and you stay at the property.

  3. 3

    Inspect each lock

    Before touching anything, we check the brand, condition, and type of each lock. Modern deadbolts and knob sets are usually straightforward to rekey. Older mortise sets, common in historic districts, need a closer look to see whether rekeying is practical or whether servicing is needed first.

  4. 4

    Rekey the cylinders

    We remove the cylinder, replace its pin configuration, and cut new keys to match. Where it makes sense, we key several locks alike so you carry one key for the front, back, and garage entry. Doors can also be keyed separately if you prefer.

  5. 5

    Test and confirm

    We test each lock with the new key, confirm the bolt throws smoothly, and verify that an old key no longer turns the cylinder. If we find a worn latch or a sticky deadbolt, we tell you plainly and explain the options.

  6. 6

    Hand over keys

    You receive the new keys and a clear explanation of what was done. For landlords, we can organize keys by unit so move-in day goes smoothly.

What affects the price

  • The number of locks or cylinders being rekeyed, since each one takes hands-on work.
  • The type and condition of the hardware, such as a standard deadbolt compared with an antique mortise lock that needs servicing.
  • How many keys you need cut and whether you want locks keyed alike or separately.
  • Whether you are booking a regular visit or calling during late-night, weekend, or holiday hours.
  • Multi-unit jobs, where several apartments are done in one visit, which differ from a single-door job in scope and planning.
  • Any repairs found along the way, such as a worn latch, loose strike, or damaged cylinder.

Why Pomona chooses us

  • Fully mobile service: we do the work at your door, with no storefront and no need to bring locks anywhere.
  • Serving the Los Angeles area since 1987, so older hardware in places like Lincoln Park is not unfamiliar territory.
  • Open 24/7, which helps when a lease ends at midnight or you discover a lost key on a Sunday.
  • Honest recommendations: if a lock is worn out and rekeying will not solve the problem, we say so rather than sell you work you do not need.
  • Able to handle multi-unit rekeying in one visit for landlords and property managers with tenant turnover.
  • Matching the method to the building, from period-style mortise sets to modern tract-home cylinders.

Lock Rekeying across Pomona

Pomona's housing mix shapes how we rekey. In the Lincoln Park Historic District, large Victorians and Craftsman homes often still have original brass mortise locks and skeleton-key sets that pre-date modern deadbolts. These are often worth keeping, and a period-appropriate rekey or on-site servicing can preserve the look of the door while giving you fresh keys. Ganesha Hills has period revival homes from the 1920s to the 1940s, where a mix of original and updated hardware is common.

Out in Phillips Ranch and the stucco subdivisions near Cal Poly Pomona, locks are typically standard residential cylinders, which makes rekeying after a home purchase quick and clean. Near Cal Poly Pomona and Western University of Health Sciences, landlords with student rentals and mid-century apartment courts often need several units rekeyed between tenants. We can do that in one mobile visit before new move-ins, including properties in ZIP code 91768 and 91767. Downtown near the Arts Colony and Antique Row on 2nd Street, loft conversions and brick buildings have their own door setups, which we assess on arrival.

We serve all of Pomona, including ZIP codes 91766, 91767, 91768, and 91769, and neighborhoods such as Westmont. Whether you are off Holt Ave or Garey Ave, or just off the I-10, SR-60, SR-57, or SR-71, call (323) 997-8867 and we will come to you.

Lock Rekeying in Pomona — FAQs

What is the difference between rekeying and changing locks in Pomona?
Rekeying changes the internal pins of your existing lock so a new key works and old keys do not. Replacing a lock swaps the hardware itself. Rekeying is often more economical and lets you keep hardware you like. Call (323) 997-8867 if you are unsure which fits.
Should I rekey after buying a home in Pomona?
Yes, it is a smart step. You cannot know how many copies of the old keys exist, including those held by previous owners, contractors, or agents. Rekeying makes sure only the keys you hold will work.
Can you rekey the original mortise locks in Lincoln Park Victorians?
Often yes, though it depends on the lock's condition. Many antique mortise sets can be serviced and rekeyed to keep the period look. We inspect on site and tell you honestly whether rekeying, servicing, or replacement makes the most sense.
Can you rekey several apartment units at once?
Yes. For landlords with student rentals near Cal Poly Pomona or other multi-unit properties, we can rekey multiple units in a single mobile visit and organize the keys by unit for tenant turnover.
Do I need to bring my locks to a shop?
No. We are fully mobile, with no storefront. We rekey the locks right on your door in Pomona, so you never have to remove hardware or travel anywhere.
Do you offer rekeying at night or on weekends?
Yes, we are available 24/7. Late-night, weekend, and holiday visits are part of what we do, and the timing can affect how a job is priced. Call (323) 997-8867 any time.
Can all my doors use one key?
In most cases, yes. We can key your front door, back door, and other entries alike, provided the locks are compatible. If you want certain doors on a separate key, we can arrange that as well.
What if my padlock seizes or a lock fails during an event at Fairplex?
That is a different problem from a standard rekey, but we can help. A seized padlock may need to be cut and replaced on site. Call (323) 997-8867 and describe what you have, and we will plan the visit.
