A lock is only as good as the cylinder inside it and the door around it. In Westmont, where so many homes date from the 1920s through the 1950s, the original hardware has often been worn down by decades of use, or swapped for a cheap builder-grade deadbolt that a bump key or a few minutes with a screwdriver can defeat. High security locks are designed to resist exactly those methods: picking, bumping, drilling and forced cylinder removal.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has seen how these upgrades play out on real doors. We are mobile only. There is no storefront to visit. We bring the hardware and tools to you, evaluate the door, and install on the spot whenever possible, at any hour.

A high security lock also comes with a restricted keyway, which means copies cannot be cut at just any hardware store kiosk. That matters for landlords, small business owners and families who want to know who holds a key. Below is how we handle these jobs in Westmont, what affects the cost, and what to expect.

How it works in Westmont

  1. 1

    Talk through the situation

    Call (323) 997-8867 any time. We ask about the door, the lock you have now, whether there has been a break-in, and what worries you most. This helps us bring the right cylinders and reinforcement.

  2. 2

    Inspect the door and frame

    On arrival we check the door material, the thickness, the strike plate and the jamb. On older stucco bungalows the wood around the latch is often cracked or loose. A strong lock in a weak frame still fails, so we tell you honestly what else needs attention.

  3. 3

    Choose the right level of protection

    We explain options such as pick-resistant and bump-resistant cylinders, drill-resistant hardening, and restricted key systems. For a storefront gate or a rental unit, we may suggest a different setup than for a private home.

  4. 4

    Install and reinforce

    We fit the new deadbolt or cylinder, and where needed add a reinforced strike plate with longer screws that reach the framing, or reinforce the door edge. For commercial roll-down gates we match the lock to the gate hardware.

  5. 5

    Test and hand over keys

    We test the lock repeatedly from both sides, confirm smooth operation, and hand you the keys along with any key card or authorization needed for later duplicates. We explain how restricted copies are ordered.

What affects the price

  • The grade and brand of the high security cylinder, including whether it has a restricted keyway with controlled duplication.
  • How many locks or doors are involved, such as a single front door versus every unit in a duplex or small apartment building.
  • The condition of the door and frame, since cracked jambs, worn strike areas or hollow doors may need reinforcement before a new lock will help.
  • Whether the job is a standard installation or a commercial application, such as a roll-down gate or storefront door with specialized hardware.
  • The number of keys you need and whether you want a master key system for a property with several units.
  • Time of day and urgency, since after-hours emergency visits following a break-in differ from scheduled upgrades.

Why Westmont chooses us

  • Fully mobile service: we come to your Westmont door, so there is no shop trip and no leaving a vulnerable entry unattended.
  • Open 24/7, which matters after a break-in when a door needs to be secured the same night.
  • Experience since 1987 with older California housing stock, including worn hardware and out-of-square doors common in 1940s bungalows.
  • We assess the whole entry, not just the cylinder, and say plainly when a strike plate, door or frame is the real weak point.
  • Comfortable with both residential and commercial work, from rental duplexes to storefront and gate locks.
  • Straightforward explanations of what a lock can and cannot resist, without exaggerated promises.

High Security Locks across Westmont

Westmont sits in unincorporated Los Angeles County, and its housing mix shapes the work we do. Along the Western Avenue corridor and the Vermont Avenue corridor, small stucco bungalows from the 1920s to 1950s sit close together on modest lots, with duplexes and small apartment buildings mixed in. Many still have original or aging locks. After a break-in on one of these homes, the usual fix is a high security deadbolt paired with a reinforced strike plate or a security door, and we carry what is needed to do that in one visit.

We also serve neighboring Vermont Knolls and West Athens, along with the commercial stretches on Imperial Highway, Manchester Avenue and Florence Avenue. Mini-malls, markets and auto shops there often rely on roll-down security gates, and a gate is only as secure as its lock. We install and repair gate locks and high security cylinders on storefronts, and we can rekey rental units when tenants turn over so old keys no longer work.

Whether you are in ZIP code 90047 near Western Avenue, in 90044, or close to Jesse Owens Community Regional Park, Washington Preparatory High School or the Vermont and Manchester area, call (323) 997-8867. We will talk through the door, the risks and the options, then come to you.

High Security Locks in Westmont — FAQs

What makes a lock high security?
High security locks use cylinders built to resist picking, bumping and drilling, and usually a restricted keyway so keys cannot be freely copied. Call (323) 997-8867 and we can explain which features suit your door.
Is a high security lock worth it on an older Westmont bungalow?
Often yes, especially if the existing deadbolt is original or builder-grade. We also check the strike plate and jamb, because on 1940s stucco homes the frame is frequently as weak as the lock.
Can you install one after a break-in at night?
Yes. We are mobile and available 24/7. Call (323) 997-8867, and we can secure the door and discuss a longer-term upgrade.
Do you handle rental duplexes and small apartments?
Yes. We can install or rekey locks between tenants and set up restricted keys so duplicates are controlled. Multiple units can also be keyed in a coordinated way.
Can you secure a storefront with a roll-down gate on Western Avenue?
We install and repair high security locks for storefront doors and roll-down gates. We look at the gate hardware first so the lock fits properly.
Will a high security lock make my door unbreakable?
No lock is unbreakable. A high security lock resists common attack methods and makes entry much harder, especially when combined with a solid door and reinforced frame.
Do I need to visit your shop?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to your home or business in Westmont.
How do I get extra keys for a restricted system?
Extra keys are typically ordered through authorized channels with proper authorization. We explain the process at handover, or you can call (323) 997-8867 later.
