A master key system sounds like a hardware purchase, but it is really a set of decisions about who can open what, and who can never open what. A good system lets an owner carry one key that opens every door, lets a manager open only the areas they supervise, and lets a part-time employee open exactly one door. When someone leaves, you deal with one key rather than rekeying the whole building by guesswork.

In Canoga Park these decisions come up constantly. Sherman Way is lined with mid-century aluminum-storefront strip retail, and the businesses inside change hands, hire seasonally, and turn over staff. Add the apartment buildings and rental stock around the neighborhood, where one tenant moves out and the next moves in, and you can see why unmanaged key rings pile up. Keys get copied at hardware counters, nobody remembers who has what, and the building's real security slowly erodes.

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, with no storefront to visit. We walk your property, learn how it is used, and build a system on paper before any cylinder is touched. Then we install and test it on site, so you leave with a key plan you can actually follow.

How it works in Canoga Park

  1. 1

    Walk the property and list every door

    We visit your location and inventory the doors: storefront entries, back doors, storage rooms, offices, utility closets, gates, and any panic hardware. We note the hardware already in place, including storefront mortise locks, deadbolts, and padlocks, and what can be rekeyed versus what should be replaced.

  2. 2

    Map who needs access to what

    We sit down with you and sort people into levels: owner, managers, staff, cleaning or maintenance crews, and outside vendors. This becomes the access hierarchy. Decisions made here determine how many key levels the system needs and where it should stay simple.

  3. 3

    Design the key plan and choose the keyway

    We lay out the system on paper: a grand master, sub-masters where useful, and change keys for individual doors. We discuss restricted keyways, which prevent keys from being casually duplicated at a hardware counter, and how that supports real key control.

  4. 4

    Install, pin, and rekey on site

    We bring the hardware to you. Existing cylinders are rekeyed to the new plan when they can be, and new cylinders are fitted where needed. Each lock is pinned to its place in the hierarchy so the master, sub-master, and change keys work as designed.

  5. 5

    Test every key against every door

    Before we leave, each key is tested on every lock in the plan, including doors it should not open. We confirm that panic hardware, door closers, and latching still work smoothly alongside the new cylinders.

  6. 6

    Hand over keys and a record

    You receive the keys and a written key schedule showing which key opens which door. We talk through issuing keys, logging who holds them, and how to add a door or a new level later without starting over.

What affects the price

  • The number of doors and cylinders in the system, since each one needs to be keyed and tested to the plan.
  • How many access levels you want: a simple master with change keys is a different job from a grand master with several sub-masters.
  • Whether you choose a restricted keyway with duplication control, or a standard keyway.
  • The condition of the existing hardware, including whether worn or mismatched locks can be rekeyed or should be replaced.
  • How many keys you need cut and issued, and whether they must be stamped or tracked.
  • Whether the work happens during normal hours or at night or on a weekend to avoid disrupting your business.

Why Canoga Park chooses us

  • We are fully mobile, so the whole design and installation happens at your property rather than through a drop-off counter.
  • We have worked in this field since 1987, and the owner, David Shar, is directly involved as lead technician.
  • We design the system on paper first and explain it plainly, so you understand your own key plan.
  • We can work with older and mixed hardware, from aging builder-grade deadbolts to storefront mortise locks and panic devices.
  • We are available 24/7, which matters when a key goes missing or an employee leaves on bad terms.
  • We provide a written key schedule, so the system can be maintained and expanded without guesswork.

Master Key System across Canoga Park

Canoga Park grew from the original 1912 Owensmouth townsite, and the building stock shows it. Around the old Sherman Way historic downtown district, near the Madrid Theatre, you find small businesses in older buildings and mid-century aluminum-storefront strips. These commonly use storefront mortise locks and panic hardware, and a master-key plan has to respect that mix. Many owners there want one clean system covering the front door, rear door, stockroom, and office without rekeying piecemeal every time staff changes.

The commercial and multi-unit picture extends beyond Sherman Way. Along Roscoe Blvd, Vanowen St, and Saticoy St, you find small offices, light commercial space, and apartment properties, including 1950s dingbat buildings and post-war courtyard complexes that have rotated through many tenants. Up toward the Gault Street and Topanga area near Warner Center, businesses sit close to Westfield Topanga and Topanga Canyon Blvd (SR-27), with different mixes of staff and vendors. For landlords, a master system lets maintenance reach common areas without carrying a ring of keys for every unit.

We serve ZIP codes 91303, 91304, 91305, and 91309, reaching sites from Victory Blvd to De Soto Ave and Canoga Ave, and from the US-101 (Ventura Fwy) corridor through the neighborhood. Whether you run a shop in 91303 or manage rental buildings elsewhere in Canoga Park, we come to you and design the system around how your property is actually used.

Master Key System in Canoga Park — FAQs

What is a master key system?
It is a keying plan in which each lock has its own key, and higher-level keys also open groups of locks. A grand master opens everything, sub-masters open sections, and change keys open single doors. Call (323) 997-8867 to discuss how it could fit your property.
Can you set up a master key system for my Sherman Way storefront?
Yes. We work with aluminum-storefront doors, storefront mortise locks, and panic hardware. We inspect what you have, then determine what can be rekeyed into the system and what should be replaced.
What is a restricted keyway and do I need one?
A restricted keyway uses key blanks that are not freely sold, so copies are harder to make without authorization. It supports stronger key control. It is a good option when employee turnover is a concern, and we can help you weigh it for your property.
We had staff turnover. Do we have to rekey everything?
Not necessarily. Often we can rekey the affected locks to a new plan and issue fresh keys. A master system makes future changes easier, since you can retire one key level instead of replacing every lock.
Can you add doors to an existing system later?
Generally yes, provided the system was designed with room to expand. This is why we leave you a written key schedule. If your current system is poorly documented, we can evaluate it first.
Do you work with landlords and apartment owners?
Yes. Many Canoga Park rentals have older builder-grade deadbolts and frequent tenant changes. A master system lets maintenance reach common areas, while tenants keep individual unit keys. Call (323) 997-8867 to talk through your buildings.
Do I need a storefront visit to start?
No. We are mobile only and have no storefront. We come to your property, walk the doors, and plan from there, at times that suit your business, including after hours.
Can you work outside normal business hours?
Yes, we are available 24/7. If you want installation done after closing so your business is not interrupted, or you need urgent help after a lost key, call (323) 997-8867.
