A master key system lets one key open many doors while each person carries only the key they need. A property manager might hold a key that opens every unit, a maintenance worker a key for utility rooms, and a tenant a key for one apartment only. Done well, it replaces a jangling ring of keys with a clear structure. Done badly, it creates security gaps no one notices until a key goes missing.

Valley Glen has plenty of places where this matters. Small apartment and condo buildings near Burbank Boulevard, rental properties around Los Angeles Valley College, offices and light-commercial spaces along Victory Boulevard and Oxnard Street, and owners with several rental houses all deal with the same problem: too many keys, too little control. A master key system, paired with a restricted keyway where it makes sense, gives you an organized way to manage that.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, with David Shar as owner and lead technician. We are mobile only, with no storefront, so the work starts with a conversation and a walk through your property. We would rather design a system that fits how you actually run your building than sell you a larger one than you need.

How it works in Valley Glen

  1. 1

    Talk through your property and your people

    We start by learning how many doors you have, who needs access to which ones, and how often occupants change. A landlord with student-adjacent rentals has different needs than an office with a few staff. Call (323) 997-8867 and we will plan a visit.

  2. 2

    On-site walk-through of existing hardware

    We come to you and look at every lock: cylinders, deadbolts, knobs, levers, and gates. Worn or mismatched hardware is noted, because a master key system is only as dependable as the locks it runs on.

  3. 3

    Design the key hierarchy

    We map out the levels: individual change keys, group or floor masters, and a grand master if you need one. We also talk about which doors should stay off the master entirely, such as a owner's storage room or an electrical closet.

  4. 4

    Choose key control level

    You can use a standard keyway or a restricted one, where blanks are not sold openly and duplication is limited to authorized people. We explain the tradeoff between convenience and control so you can decide what suits the property.

  5. 5

    Pin, install, and test every lock

    We rekey or replace cylinders to match the design, cut the keys, and test each key on each door it should open and on each door it should not. Mistakes in a master system often hide in the combinations, so testing matters.

  6. 6

    Document the system and hand over keys

    You receive a clear record of the hierarchy and key assignments, along with advice on tracking who holds what. When tenants turn over, individual doors can be changed without rebuilding everything.

What affects the price

  • The number of doors and cylinders included in the system, since each one must be pinned or replaced to fit the design.
  • How many levels the hierarchy has: a simple master over a handful of doors is less involved than a multi-level system with group and grand masters.
  • Whether you choose a standard keyway or a restricted keyway with tighter key control and authorized-duplication rules.
  • The condition and type of existing hardware, including whether older knobs, deadbolts, or cylinders can be reused or need replacing.
  • How many keys you need cut for staff, tenants, and managers, and whether you want spare sets prepared in advance.
  • Whether the work is planned during business hours or requested urgently outside normal hours, given our 24/7 mobile availability.

Why Valley Glen chooses us

  • Fully mobile service: we bring the tools and key-cutting capability to your Valley Glen property, with no storefront trip required.
  • Operating since 1987, with owner and lead technician David Shar involved in how the work is approached.
  • We design around your real situation, whether that is a condo building off Burbank Boulevard or a landlord managing college-area rentals.
  • We test every key against every door, including the doors it should not open, before we call the system finished.
  • We explain when a master key system is not the right answer, and suggest simpler rekeying or restricted keys instead.
  • Available 24/7, so if a master key is lost, we can talk through next steps at any hour on (323) 997-8867.

Master Key System across Valley Glen

Valley Glen is a quiet, stable residential neighborhood, carved out of Van Nuys and North Hollywood and recognized as its own community in the late 1990s. Most of it is 1940s and 50s single-family ranch and traditional homes on tree-lined streets, but there are pockets of apartments and condos, notably near Burbank Boulevard and around Los Angeles Valley College. Those pockets are where master key systems come up most often: multi-unit buildings, rental clusters, and small commercial spaces where several people need different levels of access.

The college district brings steady tenant turnover. A landlord with several student-adjacent rentals near Los Angeles Valley College may want each unit on its own key while keeping a single manager key, so a lost tenant key means changing one door instead of many. Along Victory Boulevard and Oxnard Street, small offices and shops can use a master system to separate staff, management, and storage areas. Properties near the Tujunga Wash and the Great Wall of Los Angeles corridor, or close to Valley Glen Community Park, have the same needs in a quieter setting.

We serve Valley Glen across ZIP codes 91401, 91405, and 91606, reaching properties from Coldwater Canyon Avenue to the CA-170 side of the neighborhood. Because we are mobile, we meet you at the property, look at the actual doors, and build the system around what is there. To start, call (323) 997-8867.

Master Key System in Valley Glen — FAQs

What is a master key system?
It is a lock arrangement where each door has its own key, and higher-level master keys open groups of doors or all of them. It lets managers, staff, and tenants have the right access without carrying many keys.
Do I need a master key system for a small Valley Glen apartment building?
Often it helps, especially if you manage several units and want one manager key plus separate tenant keys. For very small properties, simple rekeying may be enough. Call (323) 997-8867 and we can talk through what fits.
What is a restricted keyway?
It is a key profile where blanks are not freely sold, and duplication is limited to authorized people. It makes unauthorized copies harder, which is useful for rentals, offices, and shared buildings.
Can you convert my existing locks to a master key system?
Often yes. Many existing cylinders can be rekeyed into the system. Worn or incompatible hardware may need replacing, and we check this during the walk-through.
What happens if a tenant loses their key?
Because each unit has its own change key, we can rekey just that door rather than the whole system. A lost master key is more serious and may require rekeying more doors.
Do you handle college-area rentals near Los Angeles Valley College?
Yes. Landlords near the college often need tenant-turnover lock changes alongside a key structure. We can set up a system that makes turnover simpler. Reach us at (323) 997-8867.
Do I have to come to a shop?
No. We are fully mobile with no storefront. We come to your Valley Glen property, assess the doors, and do the work on site.
Can I request service outside business hours?
We are available 24/7. Planned installations are usually best scheduled in advance, but if there is an urgent key-control problem, call (323) 997-8867 any time.
