Sun Valley is not a place where a basic builder-grade lock does much work. Between the warehouses, auto-dismantlers and recycling yards along San Fernando Road and the older homes tucked below the Verdugo Mountains, the properties here face real pressure from theft, copied keys and tampering. High security hardware is built for that pressure, and choosing it well matters more than simply buying the most expensive cylinder on the shelf.

A high security lock differs from a standard one in how it is built inside. Pick-resistant cylinders use tighter tolerances and extra security pins. Bump-resistant designs defeat the common key-bumping trick. Drill-resistant units add hardened inserts that protect the shear line from a drill bit. Many systems also use restricted keyways, meaning keys can't be duplicated at a hardware-store kiosk without authorization. That last feature is often the one business owners value most after staff turnover.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, under owner and lead technician David Shar. We are mobile only, with no storefront, which means the work happens at your door, gate or roll-up. This page explains how we approach high security installs in Sun Valley, what affects the cost, and what to expect when you call.

How it works in Sun Valley

  1. 1

    Talk through the threat and the property

    We start with a phone conversation at (323) 997-8867. Tell us what happened or what worries you: a break-in at a yard, lost keys after an employee left, or an old home with weak hardware. We ask about door or gate type, current locks and who needs keys.

  2. 2

    Assess the hardware on site

    Because we are mobile, we examine the actual door, frame, gate or hasp where you are. A strong cylinder in a weak door or loose strike plate gains little, so we look at the whole point of entry and tell you honestly where the weak link is.

  3. 3

    Recommend a matching lock and key system

    We explain the options in plain terms: pick-, bump- and drill-resistant cylinders, hardened padlocks, restricted keyways and master-key layouts for multiple staff. We match the grade of hardware to the risk instead of upselling.

  4. 4

    Install and fit the hardware

    We install the new cylinders, deadbolts or gate locks, reinforce strike plates where appropriate, and make sure everything operates smoothly. On older homes we work carefully to preserve original character wherever possible.

  5. 5

    Cut keys and test everything

    We cut and test keys, confirm each lock throws and retracts cleanly, and walk you through key control: who holds which keys and how to request more under a restricted system.

  6. 6

    Follow-up guidance

    We leave you with practical advice on maintenance and key policy so the upgrade keeps doing its job long after we leave.

What affects the price

  • The lock grade and keyway type: restricted, patent-protected keyway systems cost more than standard high-security cylinders.
  • The number of locks involved, such as one front door versus a roll-up door, man-door and several gates across a yard.
  • Hardened padlocks and gate hardware, which vary widely in material, shackle protection and weather resistance.
  • Door, frame or strike reinforcement needed so the new lock isn't undermined by a weak surrounding structure.
  • How many keys you need and whether a master-key or multi-user key system is required.
  • Time of day and urgency, since we work 24/7 and after-hours emergency calls differ from scheduled upgrades.

Why Sun Valley chooses us

  • Fully mobile service: we do the work on your property, which suits yards, warehouses and sites you can't easily leave.
  • In business since 1987, with owner David Shar leading the technical work.
  • We assess the door and frame as well as the lock, so you aren't sold a cylinder that a weak door will defeat.
  • We are comfortable with both heavy commercial hardware and delicate older residential hardware.
  • Available 24/7, which matters after a break-in when a gate or door can't be left unsecured.
  • We recommend only what the risk justifies, and we explain the tradeoffs plainly.

High Security Locks across Sun Valley

Sun Valley's character shapes its lock needs. The San Fernando Road industrial corridor, running past the Pink Motel and Cadillac Jack's Cafe and toward the LADWP Valley Generating Station smokestacks, is lined with auto-dismantlers, junkyards, recycling yards and warehouses. A yard hit by a break-in often needs hardened padlocks, reinforced gate locks and restricted-key cylinders on the office and man-door. Properties off Glenoaks Boulevard, Sunland Boulevard and Vineland Avenue face similar concerns, and easy access from I-5 and CA-170 is part of why theft prevention matters here.

Near Hollywood Burbank Airport, warehouses commonly change staff and need roll-up doors and man-doors rekeyed or upgraded to restricted keys so former employees can't keep working copies. Many addresses in ZIP code 91352 are commercial or industrial, and we regularly look at hardware built for constant daily use.

On the residential side, the historic Stonehurst neighborhood, near the Stonehurst Recreation Center, has 1920s stone and clinker-brick homes, often with original hardware. Owners usually want better security without gutting period character, so we favor sympathetic deadbolt upgrades and careful rekeying. Up toward La Tuna Canyon, more isolated homes may warrant stronger door hardware too. Wherever you are in Sun Valley, call (323) 997-8867 and we will come to you.

High Security Locks in Sun Valley — FAQs

What makes a lock "high security"?
High security locks resist common attacks: picking, bumping and drilling. They use tighter tolerances, extra security pins and hardened inserts, and often a restricted keyway that prevents unauthorized key copying.
Do you serve auto-dismantlers and recycling yards on San Fernando Road?
Yes. We install hardened padlocks, gate locks and restricted-key cylinders for yards and industrial properties in Sun Valley. Call (323) 997-8867 to describe your site and we'll talk through options.
Can you rekey a warehouse after staff turnover?
Yes. We can rekey roll-up door and man-door locks, or upgrade to a restricted keyway so former staff can't have keys copied. Call (323) 997-8867 to arrange it.
Will a high security lock work on my old Stonehurst home?
Usually, yes. We choose deadbolts and hardware that fit the door and respect the home's 1920s character, and we can rekey existing hardware where it makes sense.
Do I need to replace my door too?
Not always. We inspect the door, frame and strike plate. Often reinforcement is enough, but if the door is weak we will tell you honestly.
Are you available at night or on weekends?
Yes. We are 24/7 and fully mobile, which is helpful after a break-in or when a gate must be secured right away.
Can extra keys be copied anywhere?
With restricted keyway systems, no. Duplicates require authorization, which is the point. We can cut additional keys for you as needed.
Do you have a shop I can visit?
No, we are mobile only. We come to your property anywhere in Sun Valley; call (323) 997-8867 to get started.
