A master key system lets different people open different doors with different keys, while one key tier can open them all. A property manager might carry a master, a maintenance worker might carry a key for the service areas only, and each tenant or staff member might carry a key for one suite or room. Done well, it cuts down on key rings that weigh a pound and on the guesswork over who can get in where.

In View Park-Windsor Hills, the need often looks different from a downtown office tower. There are small multi-unit buildings and duplexes, churches and community organizations, professional offices along Slauson Avenue, La Brea Avenue, and Crenshaw Boulevard, and owners who manage several homes or rental properties across the neighborhood. Many of these properties have older doors and hardware, so the design has to fit what is actually on the door rather than assuming a modern commercial setup.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are a mobile-only business, so there is no storefront to visit. We walk your property, talk through who needs access to what, and build a system around that, including restricted keyways and key control where you want to limit unauthorized copying.

How it works in View Park-Windsor Hills

  1. 1

    Walk the property and map your doors

    We come to you and look at every door that will be part of the system: entries, interior offices, utility rooms, gates, and storage. We note the existing hardware, its condition, and its brand so we know what can be rekeyed and what needs replacing.

  2. 2

    Define who needs access to what

    We talk through your people and roles: owner or manager, staff, tenants, contractors, cleaners. From that we sketch an access hierarchy, such as individual keys, group keys, and a master, so every key opens only what it should.

  3. 3

    Choose the keyway and level of key control

    You can use a standard keyway or a restricted one. Restricted keyways limit duplication to authorized requests, which matters when keys have a habit of wandering. We explain the tradeoffs so you can decide how tight control needs to be.

  4. 4

    Install and pin the locks

    We install new cylinders or rekey suitable existing ones according to the plan. On older doors, including period mortise hardware common in the area, we aim to work with the existing hardware where it makes sense rather than defaulting to replacement.

  5. 5

    Test every key on every door

    Before we leave, each key is tested on every lock in the system, including the ones it should not open. Any binding or misaligned latch gets corrected on the spot.

  6. 6

    Hand over a key record and a control plan

    We provide a clear key schedule showing which key opens which doors, plus guidance on issuing, tracking, and retrieving keys. That record is what makes future changes, like a departing employee or tenant, easy to handle.

What affects the price

  • The number of doors and cylinders included in the system, since each lock must be keyed into the plan.
  • The depth of the hierarchy, such as how many separate key levels and groups you need beyond a single master.
  • Whether you choose a standard keyway or a restricted keyway with tighter key control and authorized duplication.
  • The condition and type of existing hardware: reusable cylinders cost less effort than replacing older or worn locks and latches.
  • How many keys you need cut and issued at the outset, and whether you want extras held in reserve.
  • Whether doors need related work, such as repairs to strikes or latches, to make the system function smoothly.

Why View Park-Windsor Hills chooses us

  • Fully mobile service: we work at your property, so the design is based on the doors you really have and not a catalog guess.
  • Experience since 1987 means we have seen older mortise locks, mixed-brand hardware, and years of unmanaged keys, and we plan around them.
  • We respect period hardware. In areas with 1920s to 1940s homes and buildings, we try to preserve original character where the lock can be serviced rather than ripped out.
  • Owner-led: David Shar leads the work, so the person who understands your plan is the person standing at your door.
  • We give you a written key schedule so you are not dependent on us to understand your own system later.
  • Available 24/7, so if a key goes missing and you need locks changed or rekeyed urgently, you can call (323) 997-8867.

Master Key System across View Park-Windsor Hills

View Park-Windsor Hills sits in the hills above the Crenshaw corridor, in ZIP codes 90043, 90008, and 90056. View Park is known for its Spanish Colonial Revival, Tudor, and other period-revival homes from the 1920s through the 1940s, and the View Park Historic District, listed on the National Register of Historic Places on July 12, 2016, includes about 1,752 homes. Windsor Hills adds 1940s and 1950s mid-century houses. That mix means many doors here carry original or older hardware, and a master key plan has to be fitted to it carefully.

Who needs a system like this? Owners who manage several rentals or small apartment buildings, churches and community groups with multiple rooms and volunteers, and offices and shops on Slauson Avenue, La Brea Avenue, Overhill Drive, and Crenshaw Boulevard. A family with a large hillside property on Angeles Vista Boulevard, with a main house, guest quarters, and outbuildings, can also benefit from a simple tiered key setup.

Because we are mobile only, we come up the hills to you, whether you are near the Baldwin Hills Scenic Overlook, close to Kenneth Hahn State Recreation Area, or elsewhere in the neighborhood. In historic homes, we look at what the existing locks can support before recommending changes, so you keep the look of the door while gaining organized, controlled access.

Master Key System in View Park-Windsor Hills — FAQs

What is a master key system?
It is a lock arrangement where each lock has its own key, and one or more higher-level keys can open multiple locks. A master key can open every door in the system, while individual keys open only their assigned door.
Who in View Park-Windsor Hills typically uses one?
Landlords with multiple units, churches, community organizations, small offices along Slauson and Crenshaw, and owners with several buildings on one property. Anyone juggling many keys and many users can benefit.
Can you work with older mortise locks?
Often, yes. Many homes and buildings here have older hardware. We assess each lock and, where it can be serviced or rekeyed, we try to preserve it. If a lock cannot reliably be part of the system, we explain why and offer options.
What is a restricted key system?
It uses a keyway that is not freely available for duplication, so copies generally require authorization. It adds key control on top of the master key structure, which is useful when you need to know who holds keys. Call (323) 997-8867 to discuss options.
Do I have to replace all my locks?
Not necessarily. Some existing cylinders can be rekeyed into the system. Others may need replacement due to wear or incompatibility. We check each door during the walkthrough.
Can a master key system be changed later?
Yes. Systems can be expanded or rekeyed when staff, tenants, or needs change. Having the key schedule we provide makes later changes simpler.
Do you offer 24/7 service for this?
Yes. We are available around the clock. Planning work is usually scheduled, but if a key is lost or an urgent rekey is needed, call (323) 997-8867 any time.
Do I need to visit a shop?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to your property in View Park-Windsor Hills for the walkthrough, installation, and testing.
