A master key system sounds simple: one key opens many doors, and individual keys open only their own. In practice, a good system is a piece of planning. Someone has to decide who needs access to what, how the doors are grouped, how many levels of keys the building really needs, and what happens when a key goes missing. In Pacoima that planning looks different from one block to the next. A warehouse on the industrial corridor has different needs than a small retail suite on Van Nuys Boulevard or a multi-unit property with shared doors and individual units.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has seen what happens when keys are handed out without a plan. Employee turnover leaves unaccounted-for keys. A shop foreman carries a ring that opens everything because nobody ever separated the yard gate from the office. A property manager rekeys one door and discovers the rest of the building is still open to former tenants. A properly designed system is meant to prevent those situations.

We are a mobile-only locksmith, so there is no storefront to visit. We come to your building, walk the doors with you, and talk through how people actually move through the space. From there we design the key hierarchy, install or rekey the cylinders, and set up key control so duplicates cannot simply be made at any hardware counter. You can reach us any hour at (323) 997-8867.

How it works in Pacoima

  1. 1

    Walk the site and list every opening

    We start on location, whether that is a San Fernando Road shop, an office suite, or a multi-building property. We count every door, gate, padlock, roll-up and cabinet that needs to be keyed, note the hardware already in place, and identify which locks can be rekeyed and which should be replaced.

  2. 2

    Map who needs access to what

    Together we sketch the hierarchy: a grand master for ownership, masters for managers or departments, and individual change keys for employees, tenants, or vendors. We ask practical questions, such as who opens the yard, who closes, and which doors contractors or cleaning crews need.

  3. 3

    Choose key control level

    We explain the options, from a standard master-key setup to restricted keyways whose blanks and duplication are controlled. For a business worried about unauthorized copies, a restricted system with authorization-based duplication is usually the better fit than a conventional keyway.

  4. 4

    Install, pin, and rekey the hardware

    We bring the cylinders, pinning kits, and padlocks to your site. Existing locks are rekeyed into the system where it makes sense, and weak or worn hardware is replaced. Roll-up doors, warehouse man-doors, and gate padlocks can be brought into the same scheme.

  5. 5

    Test every key against every lock

    Before we leave, each key is tested on each door it should open and on those it should not. Mistakes in a master system are easy to introduce and hard to spot later, so we confirm the whole matrix with you present.

  6. 6

    Document and hand over key records

    You receive a clear key schedule showing which key opens which doors and how the hierarchy is organized, plus guidance on issuing, tracking, and retrieving keys. Good records are what keep a system useful years after installation.

What affects the price

  • The number of doors, gates, and padlocks to be included in the system.
  • How many levels the hierarchy needs, since adding grand master and sub-master tiers increases design and pinning work.
  • Whether you choose a standard keyway or a restricted keyway with controlled key duplication.
  • The condition of existing hardware, and how much can be rekeyed versus replaced with commercial-grade or high-security cylinders.
  • Specialty openings such as roll-up doors, yard gates, and hardened padlocks that need different hardware than standard doors.
  • The number of keys to be cut, and whether the work is planned in advance or needed after hours.

Why Pacoima chooses us

  • Fully mobile service: we work at your building, which matters when the doors in question are gates and roll-ups that cannot be carried anywhere.
  • Experience since 1987, with the owner personally involved in system design rather than handing it off.
  • We design around how your people actually work, not around a one-size-fits-all chart.
  • Honest recommendations: if a few doors need a simple rekey rather than a full system, we will say so.
  • Coverage for mixed properties, from commercial yards and warehouses to residential units that share common doors.
  • 24/7 availability for urgent follow-up, such as a lost master key or a sudden employee departure.

Master Key System across Pacoima

Pacoima's commercial life is spread across very different environments. Along San Fernando Road and the Pacoima industrial corridor, auto-repair shops, recycling yards, and warehouses depend on roll-up doors, padlocked gates, and man-doors that many different people touch in a week. After employee turnover or a theft, the question is rarely just one lock; it is whether the whole key structure still makes sense. A master or restricted system lets an owner pull back control without handing every worker a full ring.

Further toward Van Nuys Boulevard and the 'Mural Mile', small retail and office spaces have a different pattern: a few storefront doors, a back entrance, perhaps a storage room. Property managers around San Fernando Gardens and the apartment stock in Hansen Hills face another version, with shared entries, utility rooms, and individual units that need to stay separate. We work in ZIP codes 91331, 91333, and 91334, and the same planning approach adapts to each.

The area's geography makes mobile service practical. Whether you are near Whiteman Airport, close to Ritchie Valens Recreation Center & Park, or off Glenoaks or Laurel Canyon Boulevard, we come to you with the hardware needed. Contractors and vendors based in Pacoima often add fleet vehicle keys to the conversation too, and we can talk through keeping vehicle and building keys organized. Call (323) 997-8867 to start.

Master Key System in Pacoima — 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 lets owners and managers control access by role rather than carrying a separate key for every lock.
Can my existing locks be part of the system?
Often yes. Many commercial cylinders can be rekeyed into a master system. Worn, residential-grade, or mismatched hardware may be better replaced. We assess this on site. Call (323) 997-8867 to schedule a walkthrough.
What does a restricted key system add?
Restricted keyways limit who can obtain duplicate keys, because blanks are not freely available and copies require authorization. This is valuable for shops, yards, and properties where uncontrolled copies are a real concern.
Can roll-up doors and yard gate padlocks be included?
Yes. Roll-up door locks, gate padlocks, and warehouse man-doors can be brought into the same scheme, often with hardened padlocks suited to exposed yard conditions. We review each opening during the site visit.
What should I do if an employee leaves with keys?
If you have a master system, you can often rekey only the affected locks and reissue keys, rather than redoing the building. If you do not have a system yet, call (323) 997-8867 and we can discuss rekeying and designing one.
Do you come to Pacoima, or do I visit a shop?
We are fully mobile and have no storefront. We come to your location in Pacoima, including the industrial corridor, Van Nuys Boulevard, and residential properties, and we are available 24/7.
Is a master key system a security risk?
A master system does add some theoretical vulnerability compared with fully independent locks, which is why design and key control matter. Using quality cylinders, limited master key distribution, and restricted keyways reduces that risk.
Can you also help with vehicle keys for my business?
Yes. We handle van key duplication, transponder programming, and ignition work for tradespeople and vendors. It is common to review building and vehicle key control together.
