Installing a lock where none existed before is a different job from swapping an old one. There is no existing hole pattern to lean on, so the door itself matters: its material, thickness, edge, and frame. In Pomona that range is wide. A 1970s tract home in Phillips Ranch, a Craftsman near Lincoln Park, and a loft conversion downtown each need a different approach, and the right hardware depends on what the door and frame can actually support.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads our work. We are mobile only. There is no storefront to visit, so we bring tools, hardware options, and drilling equipment to your door. That means a new side gate, a freshly framed garage entry, a converted back room, or a new commercial door can be fitted and tested in one visit.

We start by asking what the door protects and who needs access. A bedroom privacy lock, a front-door deadbolt, and a keyed entry for a rental unit are all different jobs. Once we understand the goal, we recommend hardware that fits the door and your daily routine instead of upselling.

How it works in Pomona

  1. 1

    You call and describe the door

    Call (323) 997-8867 any hour. Tell us the door type (wood, hollow-core, metal, or aluminum storefront), its approximate thickness, and whether it is interior or exterior. Photos help if you can send them. This lets us bring suitable hardware to the visit.

  2. 2

    We come to you

    Because we are fully mobile, a technician drives to your home, apartment, or business in Pomona with drilling tools, door-prep equipment, and a range of deadbolts, knobsets, and lever handles. We do not make timing promises, but we are available around the clock.

  3. 3

    Inspect the door and frame

    Before drilling, we check the door for thickness, condition, and any internal framing or wiring. We also examine the strike side of the jamb, since a strong lock in a weak frame offers little protection. If the frame needs reinforcement, we explain it before work begins.

  4. 4

    Mark, drill, and fit the hardware

    We use a template to mark the bore and edge holes so the lock sits square and the bolt lines up with the strike plate. Clean cuts matter, especially on older wood doors where a sloppy hole can split the surface. We then install the latch, lock body, and trim.

  5. 5

    Install the strike and reinforce

    The strike plate is set into the jamb and secured with screws long enough to reach the framing behind it. Where appropriate, we add reinforcement hardware to the door edge or frame to make the installation stand up to real use.

  6. 6

    Test, key, and hand over

    We operate the lock repeatedly with the door open and closed, confirm smooth bolt travel, and hand over your keys. If you have several locks, we can key them alike so one key works throughout. We walk you through any adjustments you may need later.

What affects the price

  • Door material and thickness: solid wood, hollow-core, metal, and aluminum storefront doors each require different tools and time.
  • Whether the door is already bored: a fully new installation with fresh holes takes more work than fitting a lock into existing prep.
  • Lock grade and type: a basic knobset, a deadbolt, a smart lock, and a commercial-grade lever set differ in hardware cost and installation effort.
  • Number of locks and keying: several locks keyed alike, or a set of rental units, involve more hardware and setup than a single door.
  • Frame condition and reinforcement: a damaged or thin jamb may need repair or reinforcement before the new lock is secure.
  • Time of day and urgency: after-hours and same-day service differ from scheduled daytime visits.

Why Pomona chooses us

  • Fully mobile service: we bring the workshop to your Pomona door, so there is no trip to a store and no door to remove and carry anywhere.
  • Serving Greater Los Angeles and Ventura County since 1987, we have fitted locks in many eras of construction, from older wood doors to modern steel.
  • Honest recommendations: if your door cannot support the lock you asked for, we say so and suggest what will actually work.
  • We look at the frame, not just the lock, because most weak installations fail at the jamb and strike plate.
  • Available 24/7, so a new door that arrives on a Friday evening or a unit that needs a lock before a move-in does not have to wait for business hours.
  • One lead technician, David Shar, sets the standard for the work, and we explain what we are doing and why.

Lock Installation across Pomona

Pomona's housing makes lock installation a varied job. In the Lincoln Park Historic District, Victorians and Craftsman homes often have additions, converted rooms, or side doors that were never fitted with modern hardware. We pay attention to the age and grain of the wood, and we choose finishes and trim that sit comfortably on an older door rather than looking bolted on. Over in Ganesha Hills, period-revival homes from the 1920s to 1940s often have solid wood doors where careful boring matters.

In Phillips Ranch and the stucco subdivisions near Cal Poly Pomona, homes tend to have standard residential doors and frames, which makes installing a new deadbolt on a garage entry, side gate, or converted bedroom straightforward. Landlords near Cal Poly Pomona and Western University of Health Sciences often need locks fitted on added or refurbished units before a new tenant arrives, and we can handle several doors in one visit. Downtown near the Arts Colony and Antique Row on 2nd Street, loft conversions and brick commercial spaces may call for storefront or commercial-grade hardware.

We serve ZIP codes 91766, 91767, 91768, and 91769, including Westmont and the corridors along Holt Ave and Garey Ave, with easy access from I-10, SR-60, SR-57, and SR-71. Whether the job is a new door in 91767 or a business entry near Pomona Valley Hospital Medical Center, call (323) 997-8867 and we will talk through the right lock for the door.

Lock Installation in Pomona — FAQs

What does lock installation cover that a rekey or replacement does not?
Installation is for doors that have no lock, or new doors that need hardware fitted from scratch. That can include drilling the bore and edge holes and setting the strike. A rekey changes the pins in an existing lock, and replacement swaps one lock for another in existing holes. Call (323) 997-8867 if you are unsure which you need.
Can you install a lock on a door that has never had one?
Yes. We measure and template the door, drill the holes, fit the latch and lock body, and set the strike plate in the frame. We check the door and frame first to be sure they can support the lock you want.
Do you install locks in older Lincoln Park homes?
Yes. Older wood doors need careful boring so the surface does not split, and we choose hardware that suits the door. If a historic door has existing mortise hardware, we can discuss whether servicing or rekeying is a better fit than adding something new.
Can you do several apartment doors in one visit?
Yes. Landlords near Cal Poly Pomona and Western University often need multiple doors done before move-ins. We can install and key locks alike or separately. Call (323) 997-8867 with the number of doors so we can plan the visit.
Do I need to bring the lock, or do you supply it?
We can supply hardware and bring several options to the visit. If you have already bought a lock, we are happy to look at it first and confirm it fits your door's thickness and prep.
Will the new lock work with my existing keys?
Often we can key a new lock to match your existing keys, depending on the brand and keyway. We will tell you what is possible before we start.
Do you install locks on commercial or storefront doors in Pomona?
Yes. We install commercial-grade hardware on retail and office doors, including aluminum storefront doors along Holt Ave and Garey Ave. Door type determines which hardware fits, so describe it when you call.
Are you available outside normal business hours?
Yes, we are available 24/7 and fully mobile. If a new door needs securing right away, call (323) 997-8867 at any hour.
