A master key system lets one key open many doors while other keys open only their own. For a West Hills property manager, school office, medical suite, HOA, or multi-building owner, that means fewer keys on a ring, clearer control over who can go where, and a clean way to handle staff turnover. A well-designed system is planned before a single cylinder is touched.

West Hills has a mix of properties where this matters. Offices and medical suites sit along Victory Blvd, Roscoe Blvd, and Sherman Way. Gated communities off Valley Circle Blvd have gates, clubhouses, and utility rooms. Many 1960s-80s homes and small rental portfolios also benefit from a simpler arrangement, such as one key for all exterior doors with a separate key for a detached garage or workshop.

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, so every project starts with a conversation and a walkthrough at your site. We explain the options in plain language, including where a master key system adds convenience and where it adds risk, so you can choose what fits.

How it works in West Hills

  1. 1

    Talk through your needs

    We start with a call to (323) 997-8867. We ask how many doors you have, who needs access to what, and whether people like tenants, staff, vendors, or cleaners need separate levels of access.

  2. 2

    Walk the property and inventory the hardware

    Because we are mobile, we come to your site and look at every door, cylinder, and gate lock. We note what brands you have, what condition they are in, and which locks can be rekeyed versus replaced.

  3. 3

    Design the key hierarchy

    We map out the structure: change keys for individual doors, sub-masters for groups such as a floor or department, and a grand master where appropriate. We talk through the security tradeoffs of each level and put the plan in writing.

  4. 4

    Choose key control level

    You decide between standard keyways and restricted keyways, where duplication requires authorization. For sites with turnover or shared access, restricted keys make it harder for unauthorized copies to circulate.

  5. 5

    Install, pin, and test

    We rekey or install cylinders to match the design, then test every key against every lock it should and should not open. We fix anything that binds or misbehaves before we leave.

  6. 6

    Document and hand over

    You get a key schedule showing who holds what, along with guidance on issuing, tracking, and returning keys. We stay available for additions as your property changes.

What affects the price

  • The number of doors, cylinders, and gate or padlock locations included in the system.
  • The depth of the hierarchy, such as change keys only versus sub-masters and a grand master.
  • Whether existing hardware can be rekeyed or needs replacing, which is common with aging builder-grade locks.
  • The level of key control chosen, including restricted keyways and authorized-duplication programs.
  • The number of keys to be cut and how many users need them.
  • Site conditions such as multiple buildings, hillside access, gated entry, or work needed after hours.

Why West Hills chooses us

  • Mobile only: we come to your West Hills property, so the design is based on the actual doors rather than a guess.
  • Serving Greater Los Angeles and Ventura County since 1987, with owner David Shar involved in the work.
  • We explain the tradeoffs honestly, including that more levels in a master system can mean more exposure if a key is lost.
  • We test every key against every lock and leave you a written key schedule.
  • We can mix systems with smart locks, gate locks, and standard deadbolts so a property is not stuck with mismatched hardware.
  • Available 24/7, so urgent rekeys after a lost master key or staff departure do not have to wait.

Master Key System across West Hills

West Hills was part of Owensmouth and Canoga Park until it took its own name in 1987, and its buildings reflect that history. Around the Shadow Ranch area and Shadow Ranch Park, you find 1960s-80s tract homes where the original Kwikset and Schlage builder hardware is wearing out. For landlords with several rentals in 91307 or 91304, a master key system can put each property on its own key while giving the owner or manager one key that reaches all of them.

Along the Platt Ave corridor and Platt Village, along with the commercial stretches of Victory Blvd, Sherman Way, Vanowen St, and Roscoe Blvd, small offices, medical suites, and retail spaces often share keys informally. We help turn that into a structured system. Near West Hills Hospital & Medical Center, practices with staff turnover often want restricted keys so copies cannot be made at a hardware kiosk.

Up toward the Valley Circle foothills and the Bell Canyon edge in 91307 and 91308, gated developments and hillside homes bring gate, call-box, and pedestrian-gate locks into the picture. Matching a gate lock and a front door to one key, or setting up a clubhouse and utility-room hierarchy for an HOA, is a typical job. Schools like Chaminade College Preparatory and properties near Orcutt Ranch have their own access needs, and we plan around how the people there actually use their doors.

Master Key System in West Hills — FAQs

What is a master key system?
It is a set of locks designed so each lock has its own key, while higher-level keys open groups of locks or all of them. It reduces the number of keys people carry and gives you structured control over access. Call (323) 997-8867 to discuss your layout.
Can my existing locks be part of the system?
Often yes. Many quality cylinders can be re-pinned into a master system. Worn or mismatched hardware may need replacing, which we identify during the walkthrough.
What does restricted-key control mean?
Restricted keyways use blanks that are not freely sold, so duplication requires authorization. This helps in offices, rentals, and HOAs with turnover. We explain the options when we design the system.
Is a master key system a security risk?
It can add some risk because a master key opens many doors, and a lost one matters more. Good design, limited issuance, and key tracking reduce that risk, and we are upfront about the tradeoffs.
Can a homeowner in West Hills use one?
Most homes just need all exterior doors rekeyed to one key, which we do often for new owners of tract homes. A true master system makes more sense for multiple properties, a home office, or a detached structure.
Can you include gate locks in a gated community?
Yes, in many cases. We can match pedestrian gate locks, clubhouse doors, and utility rooms into one plan, depending on the gate hardware. Call (323) 997-8867 so we can look at your setup.
What happens if a master key is lost?
We can rekey the affected locks and reissue keys, sometimes redesigning the hierarchy to limit exposure. We are available 24/7, so you do not have to wait if a key goes missing.
How is pricing determined?
It depends on the number of doors, the depth of the hierarchy, hardware condition, the key control level, and the number of keys. We review these on site and explain the scope before work begins.
