A standard builder-grade lock is designed to keep honest people honest. A high security lock is built for a different job: resisting the methods that actually defeat ordinary cylinders, including picking, bumping, drilling, and the casual copying of keys. In Artesia, where a modest post-war home on a compact lot sits only a few blocks from a busy commercial strip, that difference matters for very different reasons depending on which door you are protecting.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has spent decades fitting hardware to real buildings rather than selling one product to everyone. We are a fully mobile service. There is no storefront to visit; we bring the tools, cylinders and keyways to your door, day or night, and we assess the door, frame and strike before recommending anything.

In Artesia that conversation often splits two ways. Shop and restaurant owners along Pioneer Boulevard want hardened cylinders, controlled keys, and gate or safe hardware that stands up to heavy daily use and to attempted break-ins. Homeowners in the older residential core usually want a worn deadbolt replaced with something that cannot be bumped or easily drilled, along with keys that cannot be duplicated at any hardware counter.

How it works in Artesia

  1. 1

    Talk through the doors and the risk

    Call (323) 997-8867 and tell us what you are protecting: a front door, a rear service entrance, a roll-down gate, a safe room. We ask about past break-in attempts, how many people hold keys and whether staff have changed recently, so we know what level of protection fits.

  2. 2

    On-site inspection of door, frame and strike

    A strong cylinder in a weak door is a wasted upgrade. We come to you, check the door thickness, the frame, the strike plate and the screws, and look for signs of earlier forced-entry damage. If the surrounding hardware is the weak point, we say so plainly.

  3. 3

    Choose the lock and key system

    We explain your options in plain language: pick- and bump-resistant cylinders, drill-resistant hardened inserts, and restricted keyways where duplication requires authorization. For businesses we can discuss master-keyed or tightly controlled key arrangements; for homes, simpler single-key setups.

  4. 4

    Installation and reinforcement

    We fit the new hardware, and where needed add reinforcement such as a heavier strike plate, longer screws or a frame reinforcer. Gate locks, safe locks and time-delay mechanisms are handled with the same attention to the surrounding structure.

  5. 5

    Testing, key handover and guidance

    We test every lock repeatedly from both sides, hand over your keys and any key-control paperwork or cards, and explain how to order additional keys properly. If staff leave, you will know how to have the system rekeyed rather than guessing.

What affects the price

  • The grade and type of lock chosen, since restricted-keyway and drill-resistant systems differ widely in construction and cost.
  • The number of doors, cylinders or gates being upgraded in a single visit.
  • The condition of the door, frame and strike, and whether reinforcement is needed before the lock can do its job.
  • Whether the work involves specialty hardware such as safe locks, time-delay mechanisms or roll-down gate locks.
  • The number of keys required and whether they are restricted keys that need authorized cutting.
  • Whether you need after-hours or emergency service rather than a scheduled visit.

Why Artesia chooses us

  • Fully mobile, 24/7 service: we come to your door in Artesia instead of asking you to bring anything to a shop, because we have no storefront.
  • Serving Los Angeles and Ventura County since 1987, with owner David Shar personally involved in how the work is done.
  • We evaluate the whole door assembly, not just the cylinder, so you are not paying for protection a weak frame would defeat.
  • Experience with both residential deadbolts and commercial needs such as jewelry-store safes, time-delay locks and reinforced gate locks.
  • Plain explanations of what each lock resists and what it does not; no inflated claims about any product being unbeatable.
  • We can set up key control that suits staff turnover, which matters for restaurants, groceries and retail shops that see frequent changes.

High Security Locks across Artesia

Artesia is compact, and its character shows in its doors. Around Downtown Artesia and the residential streets near Artesia Park, many homes are modest post-war single-family houses on small lots, with deadbolts that have often been in place for decades. Wear, shared keys over the years and old copies floating around make an upgrade to a pick- and bump-resistant deadbolt a practical step, especially after a lockout or a change in who lives or works at the property. These homes fall mostly within ZIP codes 90701 and 90702.

The commercial picture is different. Little India on Pioneer Boulevard is a dense strip of jewelry stores, groceries, restaurants and sari and retail shops, and many of them depend on hardware beyond a basic lock: safes, time-delay locks, reinforced steel roll-down gate locks and cylinders that take heavy daily use. A jewelry store that has had an attempted break-in might need its safe serviced, its time-delay lock checked and its gate lock reinforced. A restaurant or grocery after staff turnover often needs a rekey and new high-use commercial cylinders so former employees no longer hold working keys.

We reach Artesia easily from SR-91 and work along Pioneer Blvd, South St and Gridley Rd. Whether you are near the Artesia Historical Museum, the DES Portuguese Hall or on a quiet residential block, we come to you at any hour. Call (323) 997-8867 and we will talk through what your building actually needs.

High Security Locks in Artesia — FAQs

What makes a lock "high security"?
High security locks are designed to resist common attack methods such as picking, bumping and drilling, and many use restricted keys that cannot be copied freely. Call (323) 997-8867 and we can explain which features suit your door.
Do you offer high security locks for Pioneer Boulevard businesses?
Yes. We work with shops, restaurants and groceries in Little India on Pioneer Blvd, including hardened commercial cylinders, safe and time-delay lock service, and roll-down gate lock reinforcement.
Can a high security lock be installed on my older Artesia home?
Usually yes. Many post-war homes in Artesia can take a high security deadbolt. We check the door, frame and strike first, and reinforce them if needed so the new lock performs properly.
Do I need to replace all my locks at once?
No. Many customers begin with the main entry or the most exposed rear door and add more later. We can advise which doors matter most when we inspect the property.
Can you rekey my restaurant after staff turnover?
Yes. We can rekey existing cylinders or install new high-use commercial cylinders so old keys stop working. Call (323) 997-8867 to arrange service for your Artesia business.
Are restricted keys really harder to copy?
They are designed so that duplication requires authorization, which makes casual copying at a hardware counter much harder. No system is perfect, so we also explain good key habits.
Do you have a shop I can visit in Artesia?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to your home or business in Artesia, 24/7.
How is the price of a high security lock determined?
It depends on the lock grade, how many doors or gates are involved, the condition of the door and frame, key requirements and whether you need emergency service. We explain these factors before work begins.
