A standard builder-grade deadbolt is built to a price, and most can be defeated by someone with a little practice and the right tools. High security locks are a different category. They use tighter tolerances, hardened steel inserts, more complex pin and sidebar designs, and restricted keyways, so they resist picking, bumping and drilling far better than the hardware most properties start with. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar and our team bring that experience to every installation.

In North Hills the need shows up in a few different ways. Single-family homeowners in North Hills West often want a stronger lock on a front door that has had the same hardware since the tract was built. Property managers in North Hills East deal with frequent tenant turnover and want keys that cannot be casually copied at a hardware store. Business owners along Nordhoff Street, Roscoe Boulevard and Sepulveda Boulevard want their aluminum-frame glass doors secured with hardware that holds up after an attempted break-in.

We are mobile only, so there is no shop to drive to. We bring the hardware and tools to your door, look at the door and frame, and recommend a lock that fits the way you use the property. Sometimes that means a high security deadbolt. Sometimes it means a restricted keyway system across several doors. We will tell you honestly when a better lock will help and when the real weakness is somewhere else, like a loose strike plate or a thin door frame.

How it works in North Hills

  1. 1

    Talk through the problem

    Call (323) 997-8867 and tell us what you are protecting and what worries you: a past break-in attempt, tenant turnover, lost keys, or simply an old lock. We will ask about the door type and how many locks are involved so we arrive prepared.

  2. 2

    Assess the door, frame and existing hardware

    At your property we inspect the door material, the frame, the strike plate and the screws. A high security cylinder is only as strong as what surrounds it, so we point out weak spots like short strike screws or a worn latch before installing anything.

  3. 3

    Choose the right level of protection

    We explain the options: pick-, bump- and drill-resistant cylinders, restricted keyways that limit who can legally duplicate keys, and how they can work with a master-key system for multi-unit buildings. You decide what fits your property and comfort level.

  4. 4

    Install and reinforce

    We remove the old hardware, fit the new high security lock, and reinforce the strike and frame where needed. For storefronts with aluminum-frame glass doors, we work with the narrow-stile hardware, including Adams Rite-style deadlatches, that those doors require.

  5. 5

    Test, cut keys and hand over

    We test the lock repeatedly with the door open and closed, confirm the keys operate smoothly, and explain how to order additional keys through the proper authorization process. For multi-unit jobs we document the key hierarchy so you know who holds what.

What affects the price

  • The lock grade and brand you choose, since pick-, bump- and drill-resistant cylinders vary widely in their internal design and materials.
  • How many doors or units are involved, which matters for apartment buildings in North Hills East needing several locks or a master-key system.
  • Whether the door and frame need reinforcement, such as a stronger strike plate, longer screws or a security-screen-door replacement.
  • Door type, since a wood residential door, a steel door and an aluminum storefront door each call for different hardware and installation work.
  • Key control level, including restricted keyways and the number of keys you need cut at the time of service.
  • Time of day and urgency, as after-hours or same-day service differs from a scheduled installation.

Why North Hills chooses us

  • Fully mobile service: we come to your North Hills home, apartment complex or Nordhoff Street storefront, with no shop to visit.
  • In business since 1987, with owner and lead tech David Shar overseeing the work.
  • Available 24/7, which matters when a break-in attempt means you need a lock upgraded the same night.
  • We inspect the door and frame first and tell you plainly if a high security lock is the right fix or if something else needs attention.
  • Experience across residential, multifamily and commercial doors, from 1960s tract homes to aluminum-frame storefronts.
  • We explain key control clearly, so you understand who can and cannot duplicate your keys.

High Security Locks across North Hills

North Hills, formerly known as Sepulveda, grew out of the Mission Acres agricultural tract into postwar suburbia, and the housing reflects that history. In North Hills West, many homes are 1950s and 60s single-family tract houses, often still carrying decades-old deadbolts and worn security screen door latches. A high security deadbolt paired with a solid strike plate is a practical upgrade for these front doors. We have handled situations like a lockout at a 1960s home where the worn screen door lock was replaced at the same visit.

North Hills East is denser, with extensive 1960s and 70s dingbat and garden-apartment buildings and higher rental turnover. For property managers, restricted-keyway high security locks and a well-planned master-key system can reduce the worry about unaccounted-for keys after tenants move out, and mailbox and cluster-box locks can be addressed on the same visit. An apartment complex that has just gone through a wave of turnover is a typical candidate for rekeying multiple units and establishing a master-key system.

Along Nordhoff Street, Roscoe Boulevard and Sepulveda Boulevard, small businesses commonly have aluminum-frame glass doors that depend on Adams Rite-style deadlatches. After an attempted break-in, replacing and rekeying that hardware with a more resistant option is often the first step. Whether you are near the VA Sepulveda Ambulatory Care Center, North Hills Community Park, the Sepulveda Basin Recreation Area, or just off the I-405 or Devonshire Street, we serve all of ZIP code 91343 and the surrounding area. Call (323) 997-8867.

High Security Locks in North Hills — FAQs

What makes a lock "high security"?
High security locks use tighter tolerances, hardened components and more complex internal designs to resist picking, bumping and drilling. Many also use restricted keyways so keys cannot be freely duplicated. Call (323) 997-8867 to discuss which type suits your door.
Do you install high security locks on North Hills apartment buildings?
Yes. We work with property managers in North Hills East on rekeying multiple units, restricted keyways and master-key systems, which helps after periods of tenant turnover.
Can a high security lock be installed on my existing door?
Usually, yes, but we check the door, frame and strike first. If the door is thin or the frame is weak, we will recommend reinforcement so the new lock actually delivers the protection you are paying for.
Will you come out at night?
We are a 24/7 mobile locksmith, so you can call (323) 997-8867 at any hour. We do not make claims about specific arrival times, but we will tell you what to expect when you call.
Can you secure a storefront glass door on Nordhoff Street?
Yes. Aluminum-frame glass doors typically use narrow-stile hardware such as Adams Rite-style deadlatches. We can replace and rekey that hardware, which is common after an attempted break-in.
Can I get extra keys cut at a hardware store?
With restricted keyway systems, generally not. Duplication is controlled through authorization, which is the point. We explain the process during installation, and you can call (323) 997-8867 for additional keys.
Can you replace a worn security screen door lock too?
Yes. Security screen doors on North Hills West single-family homes often have worn latches, and we can replace them during the same visit as a lock upgrade or lockout service.
Do I need to visit your shop?
No. We are mobile only and there is no storefront. We bring everything to your home, building or business in North Hills.
