A master key system lets one key open many doors while each person carries only the key they need. A landlord with several duplexes, a shop owner with a front door, a back office, and a storage room, or a property manager with a small apartment building can all benefit. Done well, it cuts down on key rings that look like jailers' collections and makes it clear who can get in where.

In Athens, the building stock is varied. There are 1920s to 1950s bungalows and stucco homes, small apartment buildings and duplexes, and commercial strips along Broadway, Main Street, Figueroa, and Imperial Highway with roll-up security gates. Many of these properties have aging locks, mismatched keys from years of piecemeal replacement, and keys no one can account for. A master key system is a chance to clean that up and start with a clear record.

Crenshaw Lock Company has served Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are mobile only, so there is no storefront to visit. We meet you at the property, look at the doors and hardware you actually have, and design a system around how your people really use the building.

How it works in Athens

  1. 1

    Walk the property and list every door

    We come to your Athens location and go through each door, gate, padlock, and cabinet that needs keyed access. We note the existing hardware, its condition, and whether it can take the new cylinders or needs replacing.

  2. 2

    Map who needs access to what

    We sit down with you and sort out the access levels: an owner or manager key, keys for individual tenants or staff, and any shared areas like laundry rooms, utility closets, or gates. This map becomes the blueprint for the keying.

  3. 3

    Choose the system and key control level

    We explain options, from a standard master key setup to restricted keyways where duplicates can only be made with authorization. You decide how tight control needs to be, based on your risk, your turnover, and your budget.

  4. 4

    Install and rekey the cylinders

    We fit or rekey the locks so every cylinder follows the plan. Older deadbolts and worn knobs that cannot hold up are replaced rather than patched. Roll-up gate locks and storefront hardware are included when they are part of the scope.

  5. 5

    Test every key and cut the working set

    We test each key against each lock it should and should not open, then cut the keys you need. Nothing is left to guesswork, and any door that does not behave is fixed on the spot.

  6. 6

    Document the system for the future

    We give you a clear record of which key opens which doors so you can manage turnover, lost keys, and future expansion without starting from scratch.

What affects the price

  • The number of doors, gates, and cabinets that will be on the system.
  • How many access levels you need, such as tenant, staff, manager, and owner.
  • Whether you want standard keyways or restricted keyways with stronger key control.
  • The condition of existing hardware, since worn or mismatched locks may need replacing instead of rekeying.
  • The grade and type of cylinders and deadbolts chosen, including commercial-grade options for storefronts.
  • How many keys you need cut, and whether any work falls outside regular hours.

Why Athens chooses us

  • We are fully mobile and come to the Athens property, so we see the real doors before recommending anything.
  • Our work spans homes, rentals, and commercial strips, so we understand both a duplex and a Figueroa storefront with a roll-up gate.
  • We replace tired hardware honestly rather than building a system on locks that will fail.
  • We explain restricted versus standard keying plainly so you pay for the control you actually need.
  • Serving the region since 1987, with owner David Shar leading the work.
  • We provide a written record of the keying so the system stays manageable after we leave.

Master Key System across Athens

Athens sits in unincorporated Los Angeles County, wrapped by the I-110 Harbor Freeway and the I-105 Century Freeway, with Broadway, Figueroa Street, Imperial Highway, and Vermont Avenue carrying most of the traffic. We work with property owners in the Athens Park neighborhood and in neighboring West Athens, where single-family bungalows share blocks with duplexes and small apartment buildings.

For landlords in ZIP codes like 90044, 90047, and 90061, a master key system helps with a familiar problem: tenant turnover. When a unit changes hands, rekeying that one cylinder keeps the building's overall system intact, and a restricted keyway makes it harder for old copies to circulate. Near Athens Park and its community park on South Broadway, many small properties benefit from simple, durable setups rather than complicated ones.

Along the Broadway and Figueroa commercial strips, shop owners often juggle a front door, a back entry, and a roll-up security gate. We can organize those under one coherent plan so employees carry the right key and the owner keeps control. If you are ready to start, call (323) 997-8867 any time, day or night.

Master Key System in Athens — FAQs

What is a master key system?
It is a keying arrangement where each lock has its own key, and a higher-level master key opens a defined group of locks. It reduces the number of keys people carry while keeping access organized.
Is a master key system a good fit for a small rental property in Athens?
Often yes. A landlord with a few duplexes or a small apartment building can use one manager key plus individual unit keys. Call (323) 997-8867 and we can talk through your layout.
What does restricted key control mean?
Restricted keyways use key blanks that are not freely available, so duplicates generally require authorization. This helps prevent unauthorized copies from circulating among past tenants or former employees.
Can you include a roll-up security gate or storefront door?
Yes, where the hardware can be keyed into the system. Commercial strips along Broadway and Figueroa commonly have gates and doors that we can include after inspecting them.
Do my existing locks need to be replaced?
Not always. Many can be rekeyed or fitted with new cylinders, but worn or damaged hardware is better replaced. We assess each door on site before recommending anything.
What happens when a tenant moves out or an employee leaves?
You rekey only the affected lock instead of the whole property. The rest of the system continues to work, and your key record stays current.
Do you offer service outside normal business hours?
Yes. We are available 24/7 and fully mobile, though a planned master key design is usually scheduled ahead. For urgent needs, call (323) 997-8867.
Do I need to come to your shop?
No. We are mobile only and have no storefront. We come to your Athens property, do the work there, and test everything before we leave.
