A master key system lets different people open different doors with different keys, while a select few keys open many of them. In Marina del Rey that is rarely an abstract idea. A single property may include apartment units, a leasing office, a fitness room, a pool gate, trash and storage rooms, mailboxes, and a dock gate, all managed by a small staff and used by hundreds of residents and their guests.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are a mobile-only business, so there is no storefront to visit. We come to your property, walk the doors with you, and talk through who needs access to what before any hardware is chosen. That conversation matters more than the keys themselves, because a master key system is only as good as the plan behind it.

The harbor adds its own demands. Salt air, moisture, and constant sun wear on hardware, so cylinders, padlocks, and gate locks chosen for an inland office park may not last here. We factor that into the design from the start, whether you are managing a condo association, a marina-side business, or a mixed-use building near Admiralty Way.

How it works in Marina del Rey

  1. 1

    Walk-through and access discussion

    We meet you at the property and look at every opening that will be part of the system: unit doors, common areas, equipment rooms, perimeter gates, and any dock or storage access. We ask who holds keys today, who should hold them, and where past problems have come from, such as lost keys or former tenants who never returned theirs.

  2. 2

    Designing the key hierarchy

    We map out the levels of access, from a single-door change key up through area masters, a building master, and, if needed, a grand master. We explain the tradeoffs plainly: more levels add convenience but also add some security complexity, so we only recommend what your operation will actually use.

  3. 3

    Choosing hardware and key control

    We help you choose cylinders and keyways suited to the location. Where doors face the water or weather, we discuss corrosion-resistant options. If you want restricted keys, we explain how a protected keyway makes unauthorized duplication harder, and how that depends on keeping good records and authorization lists.

  4. 4

    Installation and rekeying

    We install or rekey the cylinders on site so the system works as designed. Each key is tested against the locks it should open and, just as importantly, the ones it should not. Work can be scheduled around tenant turnover, property-management hours, or quieter times at a business.

  5. 5

    Documentation and key issuing

    We provide a clear record of the system layout and which keys operate which locks, so your team is not guessing later. We recommend a sign-out routine for master keys and can talk through what to do when a key goes missing.

  6. 6

    Ongoing support and expansion

    Properties change. When you add a gate, convert an office, or turn over a block of units, we can extend the system rather than starting over, as long as the original design left room to grow. Call (323) 997-8867 any time, day or night.

What affects the price

  • The number of doors, gates, and padlocks that will be included in the system, since each opening needs a cylinder that is pinned or replaced.
  • How many levels of access the hierarchy needs, from simple change keys to multiple masters and a grand master.
  • Whether you choose standard keyways or a restricted, patent-protected key system with tighter duplication control.
  • Environmental demands, such as marine-grade cylinders and padlocks for dock gates, waterfront doors, and exposed storage.
  • Whether existing locks can be rekeyed or must be replaced, which depends on their condition and compatibility.
  • Scheduling and site conditions, including after-hours work, multiple buildings, and coordination with property management.

Why Marina del Rey chooses us

  • Fully mobile and available 24/7, so work and urgent lock problems can be handled at your property rather than at a shop.
  • In business since 1987, with owner David Shar directly involved in how local properties are keyed and secured.
  • We start with who needs access to what, not with a hardware catalog, so the system fits how your property actually runs.
  • We take salt air and moisture seriously for harbor-side doors, dock gates, and padlocks, and plan hardware around them.
  • We document the system clearly and explain its limits honestly, including what a master key system cannot do on its own.
  • We can handle related needs on the same visit, such as rekeying after tenant turnover or replacing a seized gate lock.

Master Key System across Marina del Rey

Marina del Rey is dominated by multifamily living, which is where master key systems earn their keep. Large gated communities like Mariners Village involve many buildings, shared amenity gates, and regular tenant turnover. A well-planned hierarchy lets maintenance staff reach what they need, leasing staff reach the units they manage, and residents carry only their own keys, with property-management authorization guiding any changes. Along the Admiralty Way and Via Marina apartment corridor, the dense 1970s and 80s complexes often have accumulated mixed hardware over decades, and a clean, documented system can replace that patchwork.

Then there is the water. Around the boat basins, dock gates and slip-area storage face constant salt exposure, and a padlock that has frozen solid is a familiar problem. When we design a system for a marina-adjacent property, we plan for corrosion-resistant hardware and keep in mind which locks may have to be drilled out and replaced. Businesses near Fisherman's Village, Burton Chace Park, and the Waterside and Marina Marketplace shopping areas have their own needs, such as back-of-house rooms, staff-only areas, and shared storage.

We serve addresses throughout ZIP codes 90292 and 90295, including the Silver Strand and Marina Peninsula, where some single-family beach homes and small multi-unit buildings can also benefit from a simple, restricted-key setup. Whether your property is off Lincoln Boulevard, Washington Boulevard, Culver Boulevard, or Fiji Way, we come to you. Call (323) 997-8867 to talk it through.

Master Key System in Marina del Rey — FAQs

What is a master key system?
It is a lock setup in which each lock has its own key, and higher-level master keys can open groups of locks. A property manager might hold a master for all units while each tenant's key opens only their own door.
Do you have a shop I can visit in Marina del Rey?
No. Crenshaw Lock Company is fully mobile only. We come to your property, available 24/7. You can reach us at (323) 997-8867 to arrange a visit.
Can a master key system work for a large gated apartment community?
Yes. Communities like Mariners Village often have unit doors, amenity gates, and service rooms that can all be organized under a hierarchy. We work with property-management authorization and plan around tenant turnover.
What is a restricted-key system?
A restricted-key system uses a protected keyway so keys cannot be casually copied at an ordinary key counter. It adds key control, though it works best alongside good record-keeping and a clear policy about who may authorize new keys.
Will the system hold up near the water?
Salt air is hard on hardware, so we talk with you about corrosion-resistant cylinders and padlocks for dock gates and exposed doors. No hardware is maintenance-free, but better materials help. Call (323) 997-8867 to discuss your location.
Can you add to our system later?
Often, yes. If the original design left room to grow, we can add new doors, gates, or key levels without redoing everything. We will tell you honestly if an older system cannot be extended.
Can you rekey locks as part of the installation?
Yes. Where existing locks are in good shape and compatible, rekeying can bring them into the system. Locks that are worn, corroded, or incompatible may need to be replaced.
How do I get a quote for my property?
Because pricing depends on the number of doors, key levels, hardware, and site conditions, we usually start with a conversation and a walk-through. Call (323) 997-8867 and we will help you work out the scope.
