A master key system lets the right people open the right doors with the fewest keys. A manager's key opens every room, a cleaner's key opens only the units on their route, and a tenant's key opens only their own door. Done well, it cuts the ring of keys on every belt and makes it easy to cut off access when someone leaves.

Hermosa Beach puts that need under unusual pressure. It is a dense beach town of about 1.4 square miles, and many buildings pack shared entries, side gates and multiple units onto small lots. Restaurants and bars around Pier Plaza see staff turnover. Rental owners near Downtown Pier Avenue and along The Strand / Sand Section turn over guests and cleaners constantly. Each change is a chance for keys to wander.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead tech David Shar. We are mobile only, with no storefront. We work at your property, look at the doors you actually have, and build a system around them rather than selling a one-size package.

How it works in Hermosa Beach

  1. 1

    Walk the property and list every door

    We come to your building and note each opening: front doors, back-of-house doors, storage rooms, shared gates, utility closets and unit doors. We check the condition of the existing hardware, because salt air in Hermosa Beach often leaves exterior locks corroded or sticking.

  2. 2

    Map who needs access to what

    We talk through your people: owners, managers, staff, cleaners, maintenance, tenants. From that we draft a key hierarchy showing which keys open which doors, and which levels sit above others.

  3. 3

    Choose the key system and restriction level

    We recommend a pin configuration and keyway that fit your hardware and your security goals. For properties that want tighter control, a restricted keyway means keys cannot be casually duplicated at a hardware store.

  4. 4

    Install, rekey or replace the cylinders

    We fit new cylinders or rekey existing ones to the planned hierarchy. Where a lock is too worn or corroded to hold a good system, we replace it and explain why. Panic hardware and gate locks get tested as part of the work.

  5. 5

    Cut keys, tag them and test everything

    We cut and label the keys, then test each one on each door it should open and each it should not. You get a clear key chart so you know what was issued.

  6. 6

    Set up key control going forward

    We go over simple habits: a sign-out log, who may request duplicates, and what to do when staff or tenants change. When you need a rekey or an added door later, we work from the same chart.

What affects the price

  • The number of doors and cylinders that need to be included in the system.
  • How many levels the hierarchy has, such as grand master, master and individual keys.
  • Whether you choose a standard keyway or a restricted keyway with duplication control.
  • The condition of existing hardware, since corroded or worn locks may need replacing instead of rekeying.
  • The number of keys to be cut and whether they must be stamped or tagged.
  • Whether the work is done during normal hours or needs after-hours scheduling around a business's operation.

Why Hermosa Beach chooses us

  • Fully mobile: we work on-site at your building, and there is no storefront to visit.
  • Available 24/7, which suits restaurants and bars that can only be worked on after closing.
  • Serving the area since 1987, with the owner, David Shar, leading the work.
  • We plan around coastal conditions, flagging corroded exterior hardware before it undermines a new system.
  • We write up a key chart so you know exactly who can open what.
  • We tell you honestly when rekeying existing locks will do and when replacement is needed.

Master Key System across Hermosa Beach

In Hermosa Beach, a good master key plan usually starts with how tight the properties are. Around Downtown Pier Avenue and Pier Plaza, restaurants, bars and shops share buildings and back alleys, and a staff change can mean rekeying after hours. Near the Comedy & Magic Club and the Hermosa Beach Pier, foot traffic is heavy and doors get used hard, so hardware that holds up matters.

In The Strand / Sand Section, walk-street cottages and newer three-story townhomes sit close together, often with shared pedestrian gates and entries. Rental owners here may want one key arrangement for owners, cleaners and property managers, while keeping guest access separate. Salt air is tough on every exterior lock, so we check gates and entry hardware before building a system on top of them.

East Hermosa (the Hills) has older bungalows, condos and small multi-unit buildings where a master key can simplify life for landlords and HOAs. Whether you are in ZIP code 90254 near Pacific Coast Hwy, Aviation Blvd, Artesia Blvd, Pier Ave or Hermosa Ave, call (323) 997-8867 and we will come to you.

Master Key System in Hermosa Beach — FAQs

What is a master key system?
It is a set of locks and keys arranged in a hierarchy. Individual keys open only their own doors, while master keys open groups of doors. It reduces the keys people carry and makes access easier to manage.
Can you set up a system for a restaurant or bar on Pier Plaza?
Yes. We are mobile and available 24/7, so we can work after closing. Call (323) 997-8867 to talk through back-of-house doors, storage and panic hardware.
Is a master key system useful for rental properties?
It can be. Owners, cleaners and managers can each carry keys with the right reach. Some owners near Pier Avenue prefer keypad or smart locks for guests, and we can combine those with a keyed system for staff.
What is a restricted key?
A restricted key uses a keyway with controlled distribution, so copies cannot be made easily without authorization. It adds key control, which helps when many people have had keys over time.
Can my existing locks be used?
Often yes, if they are in good shape. In Hermosa Beach, salt air corrodes exterior hardware, so we check each lock first and recommend replacement only when needed.
Do you have a shop I can visit?
No. Crenshaw Lock Company is mobile only. We come to your property anywhere in Hermosa Beach, including ZIP code 90254.
What happens when an employee or tenant leaves without returning a key?
We can rekey the affected locks so the old key no longer works. With a key chart, we can often limit the work to only the doors that person could open. Call (323) 997-8867 to arrange it.
How do I get started?
Call (323) 997-8867. We will ask about your doors and the people who need access, then visit to look at the hardware and plan the system.
