A standard builder-grade deadbolt is built to be affordable, not to resist someone who knows what they are doing. High security locks are different. They use tighter tolerances, hardened steel inserts, more complex pin and sidebar designs, and restricted key blanks, so the lock resists picking, bumping and drilling, and keys cannot be casually copied at any hardware counter. For the right door, that is a meaningful upgrade.

Hermosa Beach is a particular place to do this work. It is a dense beach town of roughly 1.4 square miles, with walk-street cottages and newer three-story townhomes pressed up against the sand, older 1920s to 1950s bungalows on the flats and in the east-side hills, condos, and a steady mix of long-term and vacation rentals. Entries are close together, gates are shared, and nearly every piece of exterior hardware lives in salt air. A lock that is perfect in a dry inland suburb can seize or corrode here within a few seasons.

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, with no storefront to visit, so the consultation, the hardware and the installation all happen at your door. We will tell you honestly when a high security cylinder is worth it and when a better-installed standard lock, a reinforced strike plate or a smart lock fits your situation better.

How it works in Hermosa Beach

  1. 1

    Talk through the door and the risk

    Call (323) 997-8867 any hour. We ask about the door type, who has keys now, whether it is a primary residence, rental or business, and what prompted the upgrade. A recent break-in attempt, a tenant turnover or a lost key set each point toward different solutions.

  2. 2

    Inspect the door, frame and existing hardware

    At your property we look at the door material, thickness, bore holes, strike plate, frame condition and any corrosion. A drill-resistant cylinder does little good in a weak frame or with short strike screws, so we check the whole assembly, not just the lock.

  3. 3

    Choose the right lock and key system

    We explain options such as restricted keyways with patent-protected key control, hardened cylinders with anti-drill and anti-bump features, and compatible deadbolts. For rentals and multi-user doors we discuss key control, rekeying flexibility and whether a keypad or smart option belongs alongside.

  4. 4

    Install and fit it properly

    We install the lock, reinforce the strike and frame where needed, and use corrosion-appropriate finishes and hardware for coastal exposure. We check that the bolt throws smoothly, the latch aligns and the door closes without forcing.

  5. 5

    Key issuance and handoff

    We test every key with you and explain how restricted blanks are duplicated, which is usually through authorization rather than a quick walk-in copy. We note any registration or card requirements so you know how to order more keys later.

  6. 6

    Maintenance guidance for salt air

    We finish by showing you how to care for the lock in a beach environment, including appropriate lubrication and rinsing habits, and what early signs of sticking or corrosion mean you should call us before a lockout happens.

What affects the price

  • The lock grade and key system you choose, since restricted keyways with key control cost more than a hardened cylinder alone.
  • The number of doors and cylinders, and whether they should all be keyed alike or kept separate.
  • Door and frame condition, including whether a reinforced strike plate, longer screws or frame repair is needed to support the new lock.
  • Corrosion and finish requirements for beach exposure, since marine-grade or specially finished hardware differs from standard options.
  • Whether existing hardware must be drilled out or removed because it has seized or corroded.
  • Timing of the visit, including after-hours or urgent service, and how many extra keys or key cards you order.

Why Hermosa Beach chooses us

  • Fully mobile service, so the whole consultation and installation happen at your door in Hermosa Beach with no shop trip.
  • In business in Greater Los Angeles and Ventura County since 1987, with owner David Shar leading the work.
  • We assess the door and frame, not just the lock, because a strong cylinder in a weak frame is a false sense of security.
  • Honest recommendations: if a standard deadbolt installed well or a smart lock suits you better, we say so.
  • Familiarity with coastal conditions, including salt-air corrosion on gate locks, mortise hardware and exterior deadbolts.
  • Available 24/7 for urgent situations such as a break-in damage repair, a lost key set or a staff change at a business.

High Security Locks across Hermosa Beach

Hermosa Beach packs a lot of different lock situations into a small footprint. Along The Strand and the Sand Section, walk-street cottages and three-story townhomes sit close to the ocean, where salt spray eats through exterior hardware and pedestrian gate locks. A corroded mortise lock on a shared walk-street gate often cannot be saved, and replacing it with a corrosion-resistant, drill-resistant unit is usually a smarter fix than repeating the same cheap swap. Many of these lots are tight, with shared entries, so key control matters when several households rely on one gate.

Downtown around Pier Avenue and Pier Plaza, the needs shift toward rentals and businesses. A rental owner near Pier Avenue may want to move away from physical keys altogether and use keypad or smart locks with rotating codes for cleaners and permitted guests, particularly given the city's rules on short-term rentals and the high turnover in the area. For bars and restaurants near the Hermosa Beach Pier, the Comedy & Magic Club and the Pier Plaza dining and nightlife district, a staff change often means after-hours rekeying and sometimes panic-hardware repair. High security cylinders with restricted keys make it much harder for former employees' copies to linger.

In East Hermosa, the hills and the older 1920s to 1950s bungalows bring wood doors, aging frames and older hardware that benefit from a careful upgrade. We serve all of 90254, from homes near South Park and the Hermosa Beach Community Center to properties off Hermosa Ave, Pier Ave, Pacific Coast Hwy, Aviation Blvd and Artesia Blvd. Call (323) 997-8867 and we will come to you.

High Security Locks in Hermosa Beach — FAQs

What makes a lock "high security"?
High security locks use tighter tolerances, hardened components, and more complex pin or sidebar mechanisms to resist picking, bumping and drilling. Most also use restricted keys that cannot be easily copied. Call (323) 997-8867 and we can explain which features suit your door.
Do high security locks hold up against salt air in Hermosa Beach?
Quality hardware with the right finish holds up much better than builder-grade locks, but no lock is immune to coastal corrosion. We recommend appropriate finishes, and simple care such as periodic cleaning and proper lubrication helps extend the life of exterior hardware.
Can you install high security locks on a walk-street gate?
Yes, in most cases. Gate locks take heavy weather exposure, so we look at the gate, latch and any shared-use needs, then recommend corrosion-resistant hardware. If an old mortise lock has seized, we may need to drill it out and replace it.
Will a new lock stop someone from copying my key?
Restricted key systems make unauthorized copying much harder because blanks and duplication are controlled. Standard hardware-store copying generally will not work. You can order additional keys through the proper authorization process, which we can walk you through.
I own a rental near Pier Avenue. Should I use high security locks or a smart lock?
It depends on how you manage guests and cleaners. Smart or keypad locks allow rotating codes without handing out keys, while high security cylinders offer strong physical resistance. Some owners combine both. Call (323) 997-8867 and we will help you weigh the trade-offs.
Can you rekey my restaurant or bar after a staff change?
Yes. We offer after-hours rekeying and can also repair panic hardware. For businesses near Pier Plaza, upgrading to a restricted keyway can help keep old keys from lingering in circulation.
Do I need a new door or frame for a high security lock?
Not always. We check the door, frame and strike first. Sometimes a reinforced strike plate and longer screws are enough, while a badly worn or damaged frame may need repair so the lock can do its job.
Do you have a storefront in Hermosa Beach?
No. Crenshaw Lock Company is fully mobile and available 24/7. We come to your home, rental or business, so there is no shop to visit. Call (323) 997-8867 to get started.
