A master key system lets one key open many doors while each door keeps its own individual key. Done well, a property manager carries a single key, a tenant carries a key that opens only their suite, and a contractor or cleaning crew gets access to exactly the areas they need and nothing more. Done badly, it becomes a tangle of duplicated keys nobody can account for. In Studio City the need shows up in very different places: a row of shops along Ventura Boulevard, a 1970s condo complex off Laurel Canyon, a production office near Radford Studio Center, or a private estate with a main house, guest house, and pool house.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar and our team design these systems on site. We are fully mobile, so there is no storefront to visit. We walk your property, look at the hardware you already have, talk through who needs access to what, and then lay out a key hierarchy that fits how your building actually runs.

A master key system is only as good as the control around it. That is why we pair the design with restricted keyways where appropriate, meaning key blanks that cannot be casually copied at a hardware store kiosk. We also help you set up a simple record of who holds which key, so that when a tenant moves out or an employee leaves, you know exactly what to change and what can stay the same.

How it works in Studio City

  1. 1

    Walk-through and access needs

    We come to your property and review every door, gate, and cabinet that should be part of the system. We ask who needs access to what: owners, managers, tenants, staff, vendors, and emergency personnel. This conversation shapes everything that follows.

  2. 2

    Key hierarchy design

    We map out the levels of the system, such as individual keys, area or floor keys, a building master, and a grand master if the property warrants one. We explain the tradeoffs plainly, because more levels of access can mean more security considerations, and we only recommend what your property needs.

  3. 3

    Hardware assessment and keyway choice

    We check whether your existing cylinders can be reused or pinned into the system, or whether new cylinders are better. For properties that want tighter control, we discuss restricted keyways that limit unauthorized duplication.

  4. 4

    Installation and pinning

    We install or rekey the cylinders on site and pin them to the agreed hierarchy. Because we are mobile, the work happens at your doors, and we can schedule around business hours, tenant schedules, or showings.

  5. 5

    Testing every lock

    Each key is tested against every lock it should open, and against the locks it should not. Master systems fail quietly when pinning is off, so we verify the whole matrix before we consider the job done.

  6. 6

    Key control and records

    We hand over the keys, help you organize a key log, and explain how to add, retire, or reissue keys later. When your needs grow, the system can be extended rather than rebuilt.

What affects the price

  • The number of doors, gates, and other locks that need to be part of the system.
  • How many levels of access the hierarchy needs, from a single master to a multi-tier layout with area keys.
  • Whether your existing cylinders can be reused or you need new hardware, including commercial-grade or high-security cylinders.
  • The keyway type: standard keyways versus restricted keyways with tighter duplication control.
  • How many keys of each level must be cut, and whether keys need to be stamped or tracked.
  • Scheduling needs, such as after-hours work around a restaurant, retail business, or occupied apartments, and the complexity of mixed hardware like aluminum storefront doors, gates, and smart locks.

Why Studio City chooses us

  • Fully mobile service: we do the design and pinning at your property, so you never have to bring locks to a shop.
  • Operating since 1987, with owner and lead tech David Shar involved in how we approach system design.
  • We work with the hardware you already have where it makes sense, rather than pushing a full replacement.
  • We explain the security tradeoffs of each access level in plain language, including when a simpler system is the better choice.
  • We test the full key matrix on site, so you find out about a problem before your tenants or staff do.
  • Available 24/7, so if a key goes missing and you need a lock changed or a system adjusted urgently, you can call (323) 997-8867 any time.

Master Key System across Studio City

Studio City is a mix of property types, and a good master key system looks different for each. Along Ventura Boulevard, the long corridor of aluminum-storefront shops and restaurants often has mixed hardware, with front doors, back-of-house doors, storage rooms, and sometimes shared alley access. A landlord with several tenants in the 91604 ZIP code can have each tenant keyed separately while keeping a single landlord key for emergencies and maintenance. Near Tujunga Village and the Studio City Farmers Market area, smaller businesses can benefit from a simple two-level system that keeps office and stockroom keys separate.

Residential and multi-unit properties have their own needs. Many 1960s to 80s condo and apartment complexes across 91602 and 91607 have common-area doors, mail rooms, garages, and laundry rooms that deserve their own key control, apart from individual units. In the Colfax Meadows and Silver Triangle neighborhoods, owners of duplexes or small rental properties sometimes want one key for themselves and separate keys for each tenant, along with a clean way to reissue keys when a tenant changes. Production-adjacent offices near Radford Studio Center often add the need to limit access by department or project.

The hillside side of Studio City adds another layer. Contemporary estates in the Fryman Canyon area and toward Laurel Canyon and Coldwater Canyon can have a main house, guest quarters, gates, and equipment rooms, along with smart locks and intercom systems. We can tie the mechanical side together, including driveway gate locks and secondary entries in 91604 and 91614, so household staff or property managers get the right access without a ring of unlabeled keys. We reach all of these areas from US-101 and the canyon roads without any storefront trip on your part, and we are available around the clock.

Master Key System in Studio City — FAQs

What is a master key system?
It is a lock arrangement where each lock has its own key, but a higher-level key can open multiple locks. A property manager might have one key that opens every unit, while each tenant's key opens only their own door.
Can you convert the locks I already have in my Studio City building?
Often, yes. Many commercial and residential cylinders can be rekeyed or repinned into a master system. We check your existing hardware during the walk-through and tell you honestly what can be reused and what should be replaced. Call (323) 997-8867 to schedule a visit.
What is a restricted keyway and do I need one?
A restricted keyway uses key blanks that are not freely available, so keys are harder to duplicate without authorization. It is a good fit for multi-tenant buildings, offices, and anywhere you want tighter key control. We will tell you whether it makes sense for your property.
Is a master key system secure?
It can be, when it is designed and managed carefully. More access levels mean more things to control, so we keep the hierarchy as simple as your needs allow and help you set up key tracking. Poorly managed key copies are the main weakness, not the system itself.
Can you set up a system for a Ventura Boulevard storefront or restaurant?
Yes. Retail and restaurant properties commonly need separate keys for the front door, back door, storage, and office, with an owner or landlord key above them. We work around your business hours so operations are not disrupted.
Do you come to me, or do I have to visit a shop?
We are fully mobile and do not operate a storefront. We come to your property anywhere in Studio City, and the work is done on site. You can reach us at (323) 997-8867.
What happens if a master key is lost?
A lost key should be addressed quickly. Depending on its level, we may rekey the affected locks or adjust parts of the system. We are available 24/7, so call (323) 997-8867 and we will talk through the options.
Can a master key system include gates and smart locks?
The mechanical locks, such as gate locks, padlocks, side doors, and the override cylinders on many smart locks, can usually be included. Electronic credentials are managed separately, but we can coordinate the mechanical side so everything works together.
