A master key system lets different people open different doors with the right key, while one key, held by the right person, opens many. In Encino that might be an office building on Ventura Blvd, a medical suite near Balboa, a property manager's portfolio of apartments, or a large estate with a main house, guest house, pool house, and staff entrances. The goal is the same: give each person only the access they need, and keep a clear record of who has what.

Good system design happens before any cylinder is pinned. We start by mapping your doors and asking who needs access to what. We also ask how often people change and what would happen if a key went missing. A tenant turnover problem, a contractor schedule, and a family with household staff all call for different hierarchies. A system built around your real situation is easier to run and safer than one copied from a template.

At Crenshaw Lock Company we have been serving Greater Los Angeles and Ventura County since 1987, under owner and lead tech David Shar. We are mobile only, with no storefront to visit. We bring the tools and knowledge to your Encino property, whether you are starting a new system, expanding an old one, or fixing a mess of unlabeled keys that nobody can account for.

How it works in Encino

  1. 1

    Walk the property and list every door

    We meet you on site and go through every opening: exterior doors, suites, utility rooms, gates, storage, and shared areas. We note the existing hardware, its condition, and which doors are used by whom. This inventory is the foundation for the whole system.

  2. 2

    Design the key hierarchy

    Together we decide the levels: individual change keys, group or floor keys, and a grand master where it makes sense. We discuss how many levels you truly need, since each added level adds some complexity and some trade-offs in security. You get a plain-language diagram of who opens what.

  3. 3

    Choose key control: standard or restricted

    For basic needs a conventional keyway may be enough. If you want to prevent unauthorized copying, we can discuss restricted keyways with controlled blanks and authorization requirements for duplicates. We explain how each option works so you can pick based on risk and budget.

  4. 4

    Install, rekey, and pin the cylinders

    We rekey existing hardware where it is sound and replace cylinders or locksets that are worn or unsuitable. Older hardware, like original mid-century locksets, may need rebuilding or replacement before it can hold a system reliably. Each cylinder is pinned to the plan and tested with its keys.

  5. 5

    Label, record, and hand over keys

    We test every key against every intended door, and just as importantly against doors it should not open. Keys are issued in an organized way, and we help you set up a key log. You leave knowing the structure and how to add or retire keys later.

  6. 6

    Support as your needs change

    Staff turn over and tenants move out. We can rekey affected cylinders, add new key levels, and extend the system while keeping the existing hierarchy intact, as long as the system was designed with room to grow.

What affects the price

  • The number of doors and cylinders in the system, and whether existing hardware can be reused or needs replacement.
  • How many levels the hierarchy has, since a simple master arrangement is less involved than a multi-level system with grand master and sub-masters.
  • Whether you choose standard keyways or a restricted, patent-protected system with controlled key duplication.
  • The condition and type of existing locks, including older mid-century locksets, high-security cylinders, or specialty hardware that may not accept master pinning.
  • The number of keys to cut and the way they are issued, labeled, and recorded.
  • Timing and site conditions, such as after-hours work, gated hillside access, or coordination with building management.

Why Encino chooses us

  • Fully mobile service: we come to your Encino property, so there is no shop to visit and nothing to transport.
  • In business since 1987, with owner and lead tech David Shar directly involved in how we approach systems.
  • We design around how your people actually use the property, not around a one-size-fits-all package.
  • We are honest about trade-offs, including that adding master levels can slightly reduce the pin security of a cylinder, and we explain when a simpler setup is the better choice.
  • We assess existing hardware first and tell you plainly if older locks should be rebuilt or replaced instead of pinned into a system.
  • Available 24/7, so urgent needs like a lost master key or a departed employee can be handled without waiting for business hours.

Master Key System across Encino

Encino is a mix of property types that each call for a different approach. Along Ventura Blvd, around Encino Commons, offices, medical suites, and luxury condos often need clearly defined access levels for tenants, management, cleaning, and maintenance. In 91436 and 91316, where commercial and residential areas sit close together, we often see buildings that have layered on keys over the years with no consistent plan. A master key system cleans that up.

North of Ventura, the flats of Encino Village hold many mid-century ranch homes and 1950s-60s houses, and some have been converted to offices or rentals. Original locksets from that era can be worn, and a remodel is a good time to rebuild or replace them before building a key system around them. In the hills south of Ventura and along Mulholland, including Amestoy Estates and Royal Oaks, larger properties often have a main house, guest quarters, gates, and storage, which suits a restricted key system that separates family, staff, and contractors. In 91436 and 91316 we regularly work with owners who also want a residential safe serviced or a high-security rekey at the same visit.

Whether you are near the Balboa Sports Complex in 91316, close to Los Encinos State Historic Park, or off Hayvenhurst, White Oak, or Burbank Blvd, we come to you. Encino is easy to reach from US-101 and I-405, and as a mobile locksteam we handle gated driveways and building check-ins as part of the job. Call (323) 997-8867 to plan your system.

Master Key System in Encino — FAQs

What is a master key system?
It is a lock arrangement where each door has its own key, and higher-level keys open groups of doors or all of them. A tenant key opens one suite, a floor key opens several, and a master opens everything. Call (323) 997-8867 to discuss what structure fits your Encino property.
Can you convert my existing locks to a master key system?
Often yes. We check whether your current cylinders and locksets can be repinned. Worn or older hardware, like original 1950s locksets, may need rebuilding or replacement first. We tell you which doors can be reused during the walk-through.
What is a restricted key system?
A restricted system uses a keyway whose blanks are controlled, so keys cannot be casually copied at a hardware store or kiosk. Duplicates require authorization. It is useful for offices, rental portfolios, and estates where you want real control over who can make keys.
Does a master key system make my locks less secure?
Adding levels does introduce some trade-offs in how cylinders are pinned, so we do not add levels you do not need. Good design, quality cylinders, and key control largely manage that. We will explain the balance honestly for your situation.
Can you set up a system for a large estate with staff and contractors?
Yes. Estates in the Encino hills commonly benefit from separate access for family, household staff, and vendors, with the owner holding the top level. We can also service safes and rekey high-security locks during the same visit. Call (323) 997-8867 to arrange it.
What if an employee or tenant leaves with a key?
Rekeying the affected cylinders can cut off that key without redoing the whole system, provided it was designed with that in mind. For a lost master key, a broader rekey may be needed. We are available 24/7 for urgent cases.
Do you have a storefront in Encino?
No. We are fully mobile and come to your location anywhere in Encino, from Ventura Blvd offices to hillside homes. That means we can do the survey and installation right where your doors are.
Can you work with building access control and condos?
For luxury condos and buildings with electronic access control, we coordinate with building management on mechanical key work like unit deadbolts and shared doors. Electronic systems are usually managed by the building, so we plan around them.
