A master key system lets one key open many doors while each door keeps its own individual key. Done well, a property manager carries one key instead of a ring of forty, a tenant's key opens only their space, and a lost key is a contained problem rather than a building-wide emergency. Done badly, it creates a tangle of overlapping keys nobody can account for. The difference is almost entirely in the planning.

Redondo Beach has a mix of properties that benefit from this kind of planning. There are small commercial buildings and shops in Riviera Village, marina storage and gate hardware around King Harbor, apartment and condo buildings near the pier, and the many attached townhome communities across North Redondo with shared gates, garages and common doors. Each has different access questions: who needs to go everywhere, who needs to go only one place, and who should never go past a certain door.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile, with no storefront, so every system is designed on site, where we can see the doors, the hardware and the way people actually move through the building. We also pair the hardware with key control, meaning restricted keyways and clear records, so copies cannot be made casually at a hardware store counter.

How it works in Redondo Beach

  1. 1

    Walk the property and learn who needs what

    We come to your building and look at every door that will be part of the system: suites, units, utility rooms, gates, garages, storage and exterior entries. We ask who needs access to what, such as owner, manager, maintenance, tenants, cleaning crews or HOA board, so the system matches real roles instead of a generic template.

  2. 2

    Design the key hierarchy

    We map out the levels of the system: individual keys, group masters for a floor or wing, and a grand master where appropriate. We keep the hierarchy as simple as the property allows, because every extra level adds complexity and some added security tradeoff. You get the plan in writing before any hardware is touched.

  3. 3

    Choose hardware and keyway restriction

    We evaluate your existing locks and decide what can be pinned into the system and what should be replaced. For properties that want key control, we recommend a restricted keyway so duplicates require authorization. Near the harbor, we also account for salt air and choose finishes and cylinders suited to corrosion.

  4. 4

    Install and pin the cylinders

    We install or rekey the cylinders to the agreed design, test each key against each door, and confirm that no key opens something it should not. Gates, padlocks and hardware that are weathered or sticking get addressed at this stage rather than left to fail later.

  5. 5

    Set up key control and hand over records

    We label and organize the keys, document the key schedule and explain how to order additional or replacement keys safely. You leave with a clear understanding of who holds which key and how to add or retire one without redoing the whole system.

  6. 6

    Support changes over time

    Tenants leave, staff turn over and keys go missing. Because the system is documented, we can rekey a single door or suite, add new cylinders, or expand to a new space, and you can reach us any hour at (323) 997-8867.

What affects the price

  • The number of doors, suites or units that will be part of the system, since each cylinder has to be pinned and tested.
  • 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 integrated or need to be replaced, including older or corroded hardware.
  • The level of key control chosen, such as a restricted keyway with authorized duplication versus a standard keyway.
  • Hardware type and grade, including gates, padlocks, deadbolts and outdoor-rated finishes for coastal exposure.
  • Site conditions and scheduling, such as work spread across several buildings or done after hours to avoid disrupting tenants.

Why Redondo Beach chooses us

  • Fully mobile service: we design the system standing in your building, not from a catalog or counter.
  • Serving Greater Los Angeles and Ventura County since 1987, with owner David Shar closely involved.
  • We plan the hierarchy in writing first, so you see exactly who will have access to what before work starts.
  • Key control is part of the conversation from the beginning, not an afterthought, including restricted keyways and clear records.
  • We account for coastal conditions, choosing hardware that handles salt air near the pier, marina and harbor.
  • Available 24/7, so a lost master key or an urgent rekey does not have to wait for business hours.

Master Key System across Redondo Beach

Redondo Beach splits naturally into two worlds, and master key needs differ between them. In South Redondo (ZIP 90277), Riviera Village's shops and offices, pier-area condos and the commercial and marina activity around King Harbor and the Redondo Beach Pier often need tidy, controlled access: staff keys, storage rooms, shared back-of-house doors and gates. Hollywood Riviera adds older hillside homes and small multi-door properties where corroded hardware has to be addressed before it can join any system.

North Redondo (ZIP 90278) is dense with attached townhomes and small-lot communities in El Nido, Golden Hills and The Avenues. Here the question is often shared access: HOA common gates, garage entries, mail and trash areas, and individual units with several exterior doors. A well-planned system can let a board or property manager reach common areas while owners keep their own keys, and a unit's front, garage and patio doors can be keyed alike to one key.

Whether the job is near Pacific Coast Hwy, along Artesia Blvd or Torrance Blvd, or close to Aviation Blvd and Inglewood Ave, we come to you. The salt air is a constant factor everywhere near the water, so we check gate hardware, padlocks and exterior cylinders for corrosion as part of the design instead of building a system on parts that are already failing.

Master Key System in Redondo Beach — FAQs

What is a master key system?
It is a set of locks designed so each door has its own key, while higher-level keys open groups of doors or all of them. A manager can carry one key, while a tenant's key opens only their own space.
Can you add my existing locks to a master key system in Redondo Beach?
Often yes, if the cylinders are in good condition and compatible. We inspect them on site and tell you what can be integrated and what should be replaced, especially older or salt-corroded hardware. Call (323) 997-8867 to schedule a visit.
What is the difference between a master key system and keyed-alike locks?
Keyed-alike locks all open with the same key and nobody has a separate key. A master system gives each door its own key plus higher-level keys that open more. Keyed-alike suits a single household, such as a townhome with front, garage and patio doors; master systems suit multi-user buildings.
What is a restricted keyway and do I need one?
A restricted keyway uses a key blank that is not freely available, so duplicates require authorization. It is worth considering for HOAs, multi-tenant buildings and businesses where uncontrolled copies would be a risk.
Can a master key system work for an HOA or townhome community?
Yes. It can organize common gates, garages, utility rooms and shared doors so the board or manager has appropriate access while each owner keeps private keys. We help plan which doors belong in the system.
What happens if a master key is lost?
It depends on the level of key lost. A lost individual key usually means rekeying one door. A lost grand master is more serious and may require rekeying much of the system. Call (323) 997-8867 any hour and we will assess it.
Do you handle marina gates and padlocks near King Harbor?
Yes. We are mobile and can service gate hardware, storage padlocks and unit locks, and we choose corrosion-resistant options because of the salt air. These can be tied into a key plan when it makes sense.
Do I need to come to a shop to set this up?
No. We are fully mobile with no storefront, so we come to your property in Redondo Beach, assess your doors in person and do the work there, any time of day or night.
