A deadbolt is the single most useful upgrade you can make to an exterior door, but only if it is the right bolt, fitted properly into a door and frame that can actually hold it. In Santa Monica that second part matters more than people expect. Many homes here are 1920s Craftsman and Spanish bungalows with original doors, old mortises, and thin strike plates, and the salt air off the Pacific quietly eats exterior hardware until a bolt that once turned smoothly will not move at all.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar has fitted deadbolts on everything from beach bungalows to mid-century courtyard apartments to newer downtown condos. We are a mobile-only service. There is no shop to visit; we bring the hardware, drill guides, and tools to your door, day or night.

Whether you are adding a first deadbolt, replacing one that has corroded or been compromised, or choosing between single and double cylinder, we explain the tradeoffs plainly and install what suits your door, your building, and how you live in it.

How it works in Santa Monica

  1. 1

    Call and describe the door

    Phone (323) 997-8867 any hour and tell us about the door: wood, metal, or aluminum, whether there is already a bolt, and what is going wrong. Details like age, a stuck bolt, or a landlord or HOA requirement help us arrive with the right hardware.

  2. 2

    Look at the door and frame

    On site we check door thickness, the existing bore holes, the edge, and the jamb. Older Santa Monica bungalow doors are sometimes worn or previously cut for other hardware, and we tell you honestly whether the door can take a new bolt cleanly.

  3. 3

    Choose single or double cylinder

    A single cylinder turns with a thumbturn inside and is the easier choice for fast exit. A double cylinder needs a key on both sides, which can suit doors with glass nearby but is a real consideration for emergency exit. We talk through it and you decide.

  4. 4

    Install and reinforce

    We fit the bolt, align the latch and bolt cleanly, and install a strike plate with long screws that reach the framing rather than just the thin jamb trim. Where corrosion or an old bolt must come out first, we remove it and clean up the opening.

  5. 5

    Test and hand over keys

    We cycle the bolt several times with the door open and closed, check that it throws fully without binding, and hand you the keys. We can key the new deadbolt to match your other locks where the hardware allows, so you carry fewer keys.

What affects the price

  • Whether you are adding a new deadbolt to a bare door or replacing an existing or seized one, since removal and repair add work.
  • The hardware grade and brand you select, from standard residential bolts to heavier, higher-security cylinders.
  • Door material and condition, including wood, metal, or aluminum, and whether the bore or edge needs correcting.
  • Single versus double cylinder, and whether you want several locks keyed alike.
  • How many doors are being done in one visit, such as a front door, back door, and gate-side entry.
  • Whether the frame or strike area needs reinforcement, and the time of day you need us, since we operate around the clock.

Why Santa Monica chooses us

  • Fully mobile since 1987: we come to your door in Santa Monica rather than asking you to bring anything to a shop.
  • Owner-led experience: David Shar has worked on older coastal doors and knows how salt air, paint buildup, and settling affect fit.
  • We replace seized, corroded exterior deadbolts and can point you toward hardware better suited to a coastal environment.
  • We explain single versus double cylinder honestly, including the emergency-exit tradeoff, instead of pushing the most expensive option.
  • We reinforce the strike and frame, not just the lock, because a deadbolt is only as strong as what it bolts into.
  • Available 24/7, so a broken or compromised lock can be secured outside business hours.

Deadbolt Installation across Santa Monica

Santa Monica's housing makes deadbolt work varied. In Ocean Park, the 1920s Craftsman and Spanish bungalows a few blocks from the sand often have exterior bolts that salt air has frozen in place; replacing one usually means removing the seized hardware and fitting a fresh bolt into the existing door. Around Sunset Park and Wilmont, you will find mid-century courtyard apartments and a large rent-controlled stock where deadbolts are added or swapped between tenants, and North of Montana, period-revival homes often deserve a bolt that suits the door's original character.

We work across all of the city's ZIP codes, including 90401 downtown near Third Street Promenade and Santa Monica Place, 90402 along the Palisades Park bluffs and Montana Avenue, 90403, 90404 near Santa Monica College and Bergamot Station, and 90405 in Ocean Park and Pico. Newer mixed-use condos downtown are often governed by HOA rules, so it is worth checking which hardware is allowed before we start.

We reach customers along Wilshire Boulevard, Lincoln Boulevard, Pico Boulevard, Ocean Avenue, and the I-10 terminus near the pier. Because we are mobile only, there is no storefront; call (323) 997-8867 and we come to you.

Deadbolt Installation in Santa Monica — FAQs

Can you replace a deadbolt that salt air has seized?
Yes. Corroded exterior deadbolts are common near the coast in Ocean Park and elsewhere in Santa Monica. We remove the seized bolt, check the door and bore, and install a new one. Call (323) 997-8867 to arrange it.
Should I choose a single or double cylinder deadbolt?
A single cylinder has a thumbturn inside, so you can leave quickly in an emergency. A double cylinder needs a key on both sides, which may suit a door with nearby glass but is a safety consideration. We help you weigh it for your door.
Do you install deadbolts at all hours?
Yes, we are available 24/7 and fully mobile. If a lock has failed or been compromised overnight, call (323) 997-8867 and we will work on securing your door.
Can a deadbolt go on my older bungalow door?
Often yes, but we inspect first. Older doors may be thin, previously drilled, or worn at the edge. We tell you if the door can take a bolt cleanly or needs some correction.
Can you key the new deadbolt to match my existing lock?
In many cases we can key the new deadbolt alike with your other locks, depending on the brands involved, so you carry one key for more doors.
I rent in a rent-controlled building. Can I add a deadbolt?
That depends on your lease and landlord. Check with your landlord or property manager first, as some require approval or specific hardware. We can install what is permitted.
Do you also reinforce the door frame?
Yes. We install strike plates with long screws that reach the framing, since a strong bolt in a weak jamb can still fail. We will point out any frame weaknesses we find.
Do you have a shop in Santa Monica?
No, we are mobile only. We come to your home or business anywhere in Santa Monica. Call (323) 997-8867 to schedule.
