A master key system lets one key open many doors while each person carries only what they need. A tenant opens their suite, a manager opens every suite on a floor, and the owner opens everything. Done well, it ends the ring of twenty keys and the question of who still has the one from three years ago. Done badly, it creates weak points and confusion. The design matters more than the hardware.

Woodland Hills is a mix that tests that design. Warner Center has office towers and high-rise residential buildings where electronic access sits next to mechanical keys. Ventura Blvd is a long commercial corridor of restaurants, medical suites, salons, and small offices with storefront doors, mortise locks, and panic hardware. Up in the hills south of the boulevard, larger estates and multi-building properties have their own needs. Each calls for a different hierarchy.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are mobile only, with no storefront, so we come to you, look at the actual doors, and build the system around how your property is used. Restricted keyways, which limit who can copy a key, can be added when control matters more than convenience.

How it works in Woodland Hills

  1. 1

    Walk the property and list every door

    We come to your site and go through each opening: suite doors, storerooms, back-of-house, mechanical rooms, gates. We note the hardware, its condition, and what each door needs, such as a deadbolt, mortise lock, or panic device.

  2. 2

    Map who needs access to what

    We sit down with you to sketch a hierarchy: individual keys, group masters for a department or floor, and a grand master. We ask about turnover, contractors, cleaning crews, and after-hours access, because those decide how the levels should be arranged.

  3. 3

    Choose the keyway and level of key control

    A standard keyway is simpler but copyable at many places. A restricted keyway limits duplication to authorized requests. We explain the tradeoff plainly so you pick the level of control you will actually maintain.

  4. 4

    Pin, rekey, or replace the cylinders

    We pin cylinders to the new hierarchy, rekeying sound hardware where it makes sense and replacing worn or poorly matched locks where it does not. Doors warped or damaged by heat or attempted entry get checked so the lock works smoothly.

  5. 5

    Test every key against every door

    Before we leave, each key is tried in each lock to confirm it opens what it should and nothing it should not. Mistakes in a master system hide until later, so we check them on site.

  6. 6

    Hand over records and a key-control plan

    You receive the key schedule showing which key opens which doors, plus guidance on issuing, tracking, and recovering keys. Good records make future additions straightforward.

What affects the price

  • The number of doors and cylinders in the system, since each one is pinned or replaced to fit the hierarchy.
  • How many levels the hierarchy needs, from simple individual and master keys to multiple group masters and a grand master.
  • Whether you choose a standard keyway or a restricted, patent-protected keyway with tighter duplication control.
  • The condition of existing hardware, including whether current locks can be rekeyed or need replacing, such as worn mortise locks or damaged panic bars.
  • Door and frame condition, including warping or break-in damage that must be corrected for locks to operate properly.
  • Integration with gates, electronic access, or smart locks, and the number of keys to be cut at the outset.

Why Woodland Hills chooses us

  • We are fully mobile, so we assess your actual doors on site instead of designing from a guess.
  • Operating since 1987 means we have seen master systems that grew messy over decades and know how to untangle them.
  • We explain the security tradeoffs of master keying honestly, including that more levels can mean more risk, and design only what you need.
  • We handle both mechanical systems and the mechanical side of electronic setups, which suits Warner Center buildings that mix fobs with keys.
  • We provide a written key schedule so you are never dependent on us to remember how your system works.
  • The lead technician, David Shar, is directly involved rather than leaving design decisions to someone who has never seen your property.

Master Key System across Woodland Hills

In Warner Center, many properties combine electronic fob access at lobbies and elevators with mechanical keys on suite doors, storerooms, and utility areas. A mechanical master system there can sit alongside building access control, and we coordinate with property management so doors and credentials fit together. Office suites in the 91367 area often need a clear split between tenant keys and the building's maintenance and emergency access.

Along Ventura Blvd, in 91364 and 91367, restaurants and shops have storefront mortise locks, back doors, and panic hardware that see hard daily use. Summer heat can warp older doors and frames, and a door that binds wears out a lock quickly. A master system for a business here usually has to cover front and rear entries, an office, and storage, while keeping staff keys limited. Small clusters of suites near Topanga Canyon Blvd and Canoga Ave benefit from group masters for shared landlord access.

South of the boulevard, in Vista de Oro, Walnut Acres, and the hills toward Mulholland Dr, larger homes and estates may have guest houses, pool houses, staff entrances, and driveway gates. A restricted-key system there keeps household staff, contractors, and family on a tidy hierarchy, especially after a purchase when every prior key is unknown. In 91364 and 91365 we work from the ground up with these properties, one door at a time.

Master Key System in Woodland Hills — FAQs

What is a master key system?
It is a lock arrangement where each door has its own key, while higher-level keys open groups of doors or all of them. It is common in offices, apartment buildings, and multi-door properties. Call (323) 997-8867 to discuss how it could fit yours.
Can you add a master system to the locks I already have?
Often yes, if the existing cylinders are in good shape and compatible. We inspect them on site and tell you which can be rekeyed into the system and which should be replaced.
What is a restricted keyway and do I need one?
A restricted keyway uses a key blank that is not freely sold, so copies require authorization. It suits properties where control of keys matters, like multi-tenant offices or estates. For simpler needs, a standard keyway may be enough. We will go over both.
Does a master key system make my building less secure?
It can introduce some added risk, since the master key opens many doors, and more levels add complexity. Careful design and good key control keep that risk manageable. We explain this plainly and do not push more than you need.
Can you work with Warner Center electronic access?
We handle the mechanical side, including suite and storeroom locks, and coordinate with building management on fobs and credentials. Call (323) 997-8867 and tell us about your building so we can plan around it.
My restaurant door is warped and I want a master system. Can that be done together?
Yes. We check the door and frame first, since a binding door damages new locks. Panic hardware and storefront mortise locks can be serviced or replaced as part of the same visit.
Do you come out at night or on weekends to set up a system?
We are available 24/7 and fully mobile. For businesses, scheduling outside working hours is often convenient, and we can arrange that when you call.
How do I keep track of keys once the system is installed?
We give you a written key schedule and suggest practices like numbered keys, a sign-out log, and prompt rekeying when keys go missing. Questions later are welcome at (323) 997-8867.
