A master key system solves a simple, expensive problem: too many keys, too many doors, and no clear record of who can open what. In Reseda, the problem shows up most often in two places. One is the mid-century apartment buildings along Reseda Blvd, Sherman Way and Victory, where a manager may carry a ring of keys that all look alike. The other is the small commercial building, where owners, employees, cleaners and vendors each need a different level of access.

A proper system arranges your locks in a hierarchy. Each tenant, employee or department has a key that opens only their own door. A master key opens a defined group of doors, and a grand master can open everything. Restricted keyways add a second layer: the key blanks are controlled, so a copy cannot simply be cut at any hardware counter. Together, these let you hand out access without handing out risk.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar and our technicians work from fully mobile service vehicles. We come to your property, look at the doors and hardware you have, and plan a system around how your building actually runs. There is no storefront; the whole job happens on site.

How it works in Reseda

  1. 1

    Walk the property and list every door

    We start by visiting the building and counting every opening that needs a lock: unit doors, mechanical rooms, storage, offices, gates and side entries. We note the existing hardware, door condition and which doors can accept new cylinders.

  2. 2

    Map who needs access to what

    Together we sketch the key hierarchy. For an apartment building that may be one key per unit, a manager master, and a maintenance key for common areas. For a business it may be separate levels for owners, staff and vendors.

  3. 3

    Choose the cylinders and keyway

    We recommend a pinning scheme and, where appropriate, a restricted keyway so duplicates are controlled. Older doors may need hardware upgrades first so the new cylinders fit and operate smoothly.

  4. 4

    Install, pin and test every lock

    We fit the cylinders, pin them to the plan and test each key against each door, including that the master works where it should and that individual keys do not cross over. We also check the door and strike alignment so the bolts throw freely.

  5. 5

    Cut, label and document the keys

    Keys are cut and organized by level. We provide a key schedule so you know which keys exist and who holds them, which is the foundation of good key control.

  6. 6

    Plan for the future

    Tenants move and employees leave. We explain how to rekey single doors within the system and how to add doors later without redoing the whole building.

What affects the price

  • The number of doors and cylinders included in the system
  • How many levels the hierarchy has, such as individual, area master and grand master
  • Whether you choose a restricted keyway with controlled key duplication
  • The condition of existing hardware, since worn or mismatched locks may need replacement before the system goes in
  • The grade and type of locks, such as standard cylinders versus high-security deadbolts
  • How many keys you need cut and whether you want a written key schedule and documentation

Why Reseda chooses us

  • Fully mobile service: we work at your building, with no storefront detour.
  • Serving the area since 1987, so older post-war hardware and layouts are familiar territory.
  • Systems are designed around how your building is used, not a one-size package.
  • We check door and frame alignment, which matters in Reseda where settled frames can make new hardware bind.
  • Available 24/7, including when a break-in attempt means you need a lock secured quickly.
  • Clear key documentation so you can see who holds which key.

Master Key System across Reseda

Reseda has a mix of buildings that benefit from key control. Along the Reseda Blvd commercial district and the Sherman Way corridor, you find small retail shops, offices and dense mid-century apartment buildings. A property manager rekeying several units between tenants is a classic case: a master key system lets one manager key cover the building while each tenant's key opens only their own door. A shop on Sherman Way recovering from an attempted forced entry may want a high-security deadbolt plus a restricted key system so staff keys cannot be casually copied.

The neighborhood's age matters too. Many buildings near Reseda Park and the post-war tract streets still carry original or builder-grade locks, and Reseda sat at the center of the 1994 Northridge earthquake, so decades of settling can leave frames out of square and deadbolts rubbing or jamming. Before installing a system we check strike plates and alignment, because a precise cylinder is only as reliable as the door it sits in.

We serve ZIP codes 91335 and 91337, from the blocks near Reseda Theatre and Reseda Recreation Center to properties along Vanowen, Victory, Saticoy, Tampa and Wilbur, out toward the Sepulveda Basin. Call (323) 997-8867 any hour to plan a system for your property.

Master Key System in Reseda — FAQs

What is a master key system?
It is a set of locks arranged so each door has its own key, while a master key opens a defined group of doors. A grand master can open all of them. It reduces the number of keys you carry and gives you control over access.
Is a master key system a good fit for a Reseda apartment building?
Often, yes. With many units turning over along Reseda Blvd and Sherman Way, a master system lets a manager access every unit while tenants only open their own. Call (323) 997-8867 and we can talk through your building.
What is a restricted keyway?
It is a keyway whose blanks are controlled, so duplicates generally cannot be cut at ordinary key counters. It adds protection against unauthorized copies, which is helpful for businesses and multi-unit properties.
Can you convert my existing locks into a system?
In many cases we can rekey or replace cylinders to fit a new hierarchy, depending on the hardware. We inspect the doors first. Very old or worn locks may need replacing.
Do you work on older post-war doors and frames?
Yes. Many Reseda buildings date from the 1940s and 50s and have settled frames. We check alignment and adjust strikes so the new hardware works smoothly.
Can I add doors to the system later?
Generally yes. A well-planned system leaves room to add doors or levels. We document the layout so future work fits what is already in place.
Do you come to my location?
Yes. We are fully mobile and serve Reseda 24/7, with no storefront. Call (323) 997-8867 to arrange a visit.
What if a tenant loses a key?
Individual doors can usually be rekeyed within the system without touching the rest. Call (323) 997-8867 and we will explain the options for your setup.
