A master key system lets different keys open different locks in a planned hierarchy. A property manager might carry one key that opens every door, while a tenant or employee carries a key that opens only their own space. Done well, it cuts down the ring of keys people carry and gives you a clear record of who can get in where. Done badly, it creates confusion and security gaps. The difference is almost entirely in the planning.

Agoura Hills has a mix of properties where this makes sense. Aluminum-storefront retail and office space along Agoura Rd and Kanan Rd, condo and townhome communities around Lake Lindero, and horse properties with barns, gates and outbuildings in Old Agoura all have the same underlying problem: too many locks and too many people who need access to some of them, but not all of them.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are mobile only, so there is no shop to visit. We come to your site, look at your doors, gates and padlocks, and build a system around how your property is actually used. We can also set up restricted keyways, which means keys that cannot be copied at a typical hardware-store kiosk without authorization, and that is the foundation of real key control.

How it works in Agoura Hills

  1. 1

    Walk the property and list every lock

    We start on site. We note each door, gate, padlock, mailbox lock and cabinet, along with the hardware brand and condition. For a Lake Lindero cluster that might mean common-area doors and mailbox banks. For a ranch it might mean the main house, barn, tack room and driveway gate.

  2. 2

    Map who needs access to what

    We sit down with you and sketch the hierarchy: who holds a top-level key, who holds a group key and who holds a single-door key. We ask about staff turnover, tenants, vendors and contractors, because those groups shape how the system should be built.

  3. 3

    Choose the keyway and level of key control

    We recommend hardware that fits your goals. A restricted keyway limits who can duplicate keys, while a standard keyway is simpler and more flexible. We explain the tradeoffs plainly so you can decide how tight the control needs to be.

  4. 4

    Pin and install the cylinders

    We rekey compatible existing locks into the system and replace any that are worn, mismatched or unable to be pinned for master keying. Worn gate locks and weathered padlocks are common trouble spots and are replaced rather than patched.

  5. 5

    Test every key and every lock

    Before we leave, we run each key through each lock it should and should not open. A master key system only works if the hierarchy behaves exactly as designed, so we verify it on site.

  6. 6

    Hand over the key records

    We give you a key chart and a clear way to track who holds what. We also explain how to order additional keys so that duplication stays under your control as your staff or residents change.

What affects the price

  • The number of locks and doors that need to be included in the system.
  • How many levels the hierarchy has, such as a grand master, sub-masters and individual keys.
  • Whether you choose a restricted keyway with controlled duplication or a standard keyway.
  • The condition of your existing hardware and how many locks must be replaced rather than rekeyed.
  • The type of hardware involved, such as deadbolts, commercial cylinders, padlocks, gate locks or mailbox locks.
  • The number of keys you need cut, and whether you want us to manage future key orders.

Why Agoura Hills chooses us

  • We are fully mobile and available 24/7, so we work around your business hours or your HOA schedule instead of asking you to come to a shop.
  • We have served Greater Los Angeles and Ventura County since 1987, and David Shar leads the design work.
  • We plan around how your property is used, not around a one-size template, whether it is a retail strip, a townhome community or a horse property.
  • We test every key against every lock before we finish, so you do not discover a hierarchy mistake later.
  • We explain the tradeoffs of restricted versus standard keyways honestly, including when a simpler system is the better choice.
  • We can handle the mixed hardware found on real properties, from commercial doors to rural gates and padlocks.

Master Key System across Agoura Hills

Agoura Hills properties vary a lot, and a good key system reflects that. Along Agoura Rd and Kanan Rd, aluminum-storefront retail and office suites often share a landlord and several tenants. A master key plan lets a property manager reach common areas while each tenant controls their own suite. Near Whizin's Market Square and the Canyon club area, that kind of layered access is a natural fit.

Around Lake Lindero, condos and townhomes are usually managed by an HOA with shared doors, gates and cluster mailboxes. Rekeying those common-area locks into one organized system, with a restricted keyway to discourage unauthorized copies, helps a board keep track of who has access as residents and vendors come and go. We serve addresses across both 91301 and 91376.

Out in Old Agoura, the needs are different. Horse properties may have a main house, a barn, a tack room and a driveway gate that has seen years of weather. Morrison Ranch and the 1970s and 80s tract homes off Kanan Rd often have aging deadbolts that benefit from being brought into one keying plan. Whether you are near Chumash Park, close to the US-101 corridor or up toward Ladyface Mountain, we come to you at any hour. Call (323) 997-8867.

Master Key System in Agoura Hills — FAQs

What is a master key system?
It is a keying plan where each lock has its own key, and higher-level keys can open groups of locks or all of them. It reduces the number of keys people carry while keeping control over who can enter which areas.
Can my Agoura Hills HOA use a master key system for common areas?
Yes. HOAs, such as those around Lake Lindero, often use one for common-area doors, gates and cluster mailbox locks. Call (323) 997-8867 and we can talk through what your community has.
What is a restricted keyway?
It is a keyway whose blanks are not sold openly, so keys generally cannot be copied at a typical key kiosk. Duplication goes through an authorized process, which gives you real key control.
Can you convert my existing locks into a master key system?
Often yes. Many cylinders can be re-pinned into a system, but worn or incompatible locks need replacing. We inspect on site and tell you which is which before any work begins.
Does a horse property in Old Agoura need a master key system?
It can help. A ranch with a house, barn, tack room and gate can have a plan where family and ranch hands carry only the keys they need. We can also replace worn gate locks and padlocks.
Do you offer this service outside business hours?
Yes. We are a 24/7 mobile locksmith, so we can schedule work in the evening or on weekends, or respond if a lock fails. Call (323) 997-8867.
What happens when an employee or tenant leaves?
A well-designed system can limit the impact. Depending on which key was lost, we can rekey only the affected locks instead of the whole property, which is a main benefit of the hierarchy.
Do you have a shop I can visit?
No. We are mobile only and come to your home, business or community. That lets us see your actual doors and gates, which is how we design the system properly.
