A master key system lets one key open many doors while each door still keeps its own individual key. Done well, a property manager carries one key, each tenant or department carries only theirs, and nobody can open more than they should. Done badly, it becomes a pile of unmarked keys and a lock layout nobody can explain. Moorpark has a bit of everything that benefits from the first approach: downtown commercial buildings, multi-unit properties, offices near the Moorpark Metrolink Station, and farm and ranch properties with many gates and outbuildings.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are mobile only. There is no storefront to visit, so we do the planning walk-through, the cylinder work and the key cutting at your property, whether that is a brick building on High Street or a barn complex off Los Angeles Ave.
A master key system is as much about planning as hardware. Before any cylinder is pinned, we talk through who needs access to what, how the building is organized, how likely staff or tenants are to change, and how much you want to prevent unauthorized key copying. A restricted keyway, where blanks and duplication are controlled, can be added when copying risk matters.
How it works in Moorpark
- 1
Walk-through and access mapping
We visit your property and list every door, gate and cabinet that needs a lock. Together we decide who should open what: individual tenants, department heads, maintenance, and an owner-level key. This map becomes the foundation of the whole system.
- 2
Designing the key hierarchy
From your access map we lay out the levels: change keys for single doors, group masters for sets of doors, and a grand master where it makes sense. We also flag areas, like a server closet or cash room, that should sit outside the master entirely.
- 3
Choosing hardware and keyway
We evaluate your existing locks and decide what can be rekeyed and what should be replaced. For historic mortise locks in older downtown buildings, we discuss whether to keep the original hardware or add compatible cylinders. If copying control matters, we recommend a restricted keyway.
- 4
Pinning, installing and testing
We pin cylinders to the designed hierarchy, install them on site, and test every key against every lock it should and should not open. Catching a cross-keying problem on day one is far easier than discovering it later.
- 5
Key issuance and records
We cut and label keys, and help you set up a key log recording who holds what. Without clear records the system loses its value, so we walk you through a simple method for tracking issuance and returns.
- 6
Future changes and expansion
A good system leaves room to grow. When you add a suite, replace a lost key, or onboard a new tenant, we can extend the hierarchy rather than start over, as long as the original design planned for it.

What affects the price
- The number of doors, gates and cabinets that need cylinders, since each opening adds hardware and labor.
- How many levels the hierarchy needs, from a simple master and change keys to multiple group masters and a grand master.
- Whether existing locks can be rekeyed or must be replaced, which depends on their condition, brand and age, especially in older buildings.
- Whether you want a restricted keyway with controlled blanks and duplication, which is a different product than standard keyways.
- The mix of hardware types, such as modern deadbolts, historic mortise locks, padlocks and gate locks.
- How many keys you need cut and whether you want labeling, and key records support, as part of the job.
Why Moorpark chooses us
- We are fully mobile and do the design, installation and key cutting at your Moorpark property, with no shop trip for you.
- Service since 1987 means we have worked with older mortise and skeleton-key hardware as well as modern cylinders.
- The owner and lead technician, David Shar, is involved in the work, so planning is not handed off to a call center.
- We design around how you actually operate, and tell you honestly when a simple rekey will do instead of a full master system.
- We test every key against every lock before we leave, so cross-keying surprises do not turn up later.
- We are available 24/7 for urgent lock problems, so if a key is lost or a door fails, you are not waiting for business hours.
Master Key System across Moorpark
Moorpark's mix of properties makes master keying useful in several ways. In Old Town Moorpark along High Street, early-20th-century brick and wood commercial buildings, some still carrying original mortise locks, often have a patchwork of keys built up over decades. Near the High Street Arts Center, a business owner may want a tidy system that keeps historic character while giving staff and landlords controlled access. We can work with period hardware where it makes sense rather than stripping it out.
Elsewhere in town, property managers and small commercial owners in the 93021 area, and around Tierra Rejada Rd, Spring Rd and Princeton Ave, may manage several suites or units that benefit from a master and individual keys. In neighborhoods like Peach Hill and Mountain Meadows, where newer homes increasingly use smart locks, we can help landlords or HOAs think about how mechanical master keying and electronic access fit together. Properties serving Moorpark College and Campus Park may also have many users and shared spaces, which suits layered key control.
On the agricultural fringe along Los Angeles Ave near Underwood Family Farms, ranch and farm properties often have barns, equipment sheds and gates that all need different people to have access. A master system with keyed-alike padlocks or gate locks can cut a ring of a dozen keys down to a few. Our reach extends to ZIP 93020 and across the SR-23 and SR-118 corridors, and we come to you because we have no storefront.
