A lock is only as strong as its weakest part, and in Lomita that is often the original hardware. Many homes here date from the 1940s through the 1960s, and plenty of them still carry builder-grade deadbolts that have been turned thousands of times. High security locks address the ways ordinary pin-tumbler cylinders get defeated: picking, bumping, drilling and unauthorized key copying.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are mobile only. There is no storefront to visit, so the work happens at your door, whether that is a single-family home off Narbonne Avenue, a small apartment building near Lomita Boulevard, or a detached garage out back.

High security is not about piling on hardware for its own sake. It is about matching the lock to the real risk: a door that faces an alley, a unit with frequent tenant turnover, a garage holding tools, or a home where you want control over who can copy a key. We walk through those questions first, then install what actually fits.

How it works in Lomita

  1. 1

    Talk through your situation

    Call (323) 997-8867 any hour. We ask about the door, who has keys now, whether you have lost keys, and what worries you. That helps us recommend a sensible level of protection rather than the most expensive one.

  2. 2

    Inspect the door and frame

    A strong cylinder in a weak door does little. On site we look at the door material, the strike plate, the screws, the frame and the gap around the latch, since older Lomita homes often have worn wood or shallow strike screws.

  3. 3

    Choose the lock and key system

    We explain options such as drill-resistant hardened cylinders, bump-resistant pin designs and restricted keyways, where key blanks are controlled and cannot be freely copied at a hardware kiosk. You choose what suits the property.

  4. 4

    Install and reinforce

    We remove the old hardware, fit the new deadbolt or cylinder, and reinforce the strike plate and frame where needed. If you want the house and garage keyed alike, we set that up so one key works for both.

  5. 5

    Test, hand over keys, explain copying

    We check the lock operates smoothly from both sides, confirm the door latches properly, and hand over your keys. We also explain how additional keys can be made for restricted systems so you know how to get copies later.

What affects the price

  • The grade and type of lock chosen, since restricted-keyway and drill-resistant cylinders differ in construction and cost from standard deadbolts.
  • How many doors or cylinders are involved, including whether a garage, side door or laundry room should be keyed alike to the main entry.
  • The condition of the door and frame, because worn strike plates, loose frames or damaged bores may need reinforcement or repair before a new lock performs well.
  • Whether you need rekeying of existing compatible hardware versus full replacement of the lock body.
  • The number of keys you want cut and whether they come from a restricted system with controlled duplication.
  • Timing and location of the visit, such as an after-hours call versus a scheduled appointment.

Why Lomita chooses us

  • Fully mobile service: the work is done at your door in Lomita, with no shop trip and no leaving the property unsecured.
  • In business since 1987, so David Shar and the team have seen decades of Southern California hardware, including the aging post-war locks common here.
  • We start with the door and frame, not just the cylinder, because security depends on the whole assembly.
  • We explain tradeoffs honestly, including when a standard quality deadbolt is enough and when a restricted system makes sense.
  • Multi-unit friendly: we can handle rekeys and replacements for small apartment properties between tenants while keeping key records organized for the manager.
  • Available 24/7, so a break-in scare or a lost key does not have to wait for business hours.

High Security Locks across Lomita

Lomita is a compact city of roughly 1.9 square miles, incorporated in 1964, and its housing mix shapes the locks people ask about. In the Harbor Hills area and on the streets around the Narbonne Avenue corridor, modest single-family homes from the 1940s to 1960s are common. A typical call is an owner whose worn exterior deadbolts need replacing and who wants the house and detached garage keyed alike so one key does everything.

Along Lomita Boulevard and the City Center area, small apartment buildings and condos from the 1960s to 1980s create a different need. Property managers often want two units rekeyed between tenants and a laundry-room padlock swapped out. A restricted key system can help here, since keys cannot easily be copied without authorization. If you manage a building in ZIP code 90717, we can plan the work unit by unit.

Lomita also sits at the gateway to the Palos Verdes Peninsula, just off Pacific Coast Highway, with Western Avenue and Narbonne Avenue leading uphill. Some residents head to gated communities and need a lost mailbox or gate key duplicated, or a lockout resolved. Whether you live near Lomita Park, the Railroad Museum, or the foothill horse-keeping parcels, we come to you around the clock. Call (323) 997-8867.

High Security Locks in Lomita — FAQs

What makes a lock high security?
High security locks are built to resist common attacks: picking, bumping and drilling. Many also use restricted keyways so key blanks and copying are controlled. We can explain which features apply to each lock we offer.
Do I need high security locks for an older Lomita home?
Not always, but older post-war homes often have worn original deadbolts and thin strike plates. After inspecting your door, we will tell you honestly whether an upgrade is worthwhile. Call (323) 997-8867 to discuss it.
Can you key my house and detached garage alike?
Yes. We can set up the main entry and garage locks to work with one key, which is a frequent request for 1950s single-family homes near Narbonne Avenue.
Can you rekey apartment units between tenants?
Yes. We can rekey individual units and replace shared-area padlocks, such as a laundry room, so previous tenants' keys no longer work. Managers can call (323) 997-8867 to plan it.
How do I get extra copies of a restricted key?
Restricted keys are intentionally harder to copy. We explain the process at handover so you know how to get additional keys authorized and cut, without using an ordinary copy machine.
Will a better lock help if my door frame is weak?
A strong lock needs a solid door and frame. We check the strike plate, screws and frame and can reinforce them, since that is often where forced entry succeeds.
Do you have a shop I can visit in Lomita?
No. We are fully mobile and do all work at your location. We are available 24/7, so just call (323) 997-8867 and we will come to you.
Can you help if I am locked out and also want better locks?
Yes. We can resolve the lockout first, then talk through upgrades if you want them. Many customers deal with both in a single visit.
