A standard deadbolt keeps honest people honest. A high security lock is built for the person who is not: it uses tighter tolerances, hardened pins and inserts, and key control so that picking, bumping, drilling and unauthorized key copying become far harder. In a city as varied as Torrance, with its Craftsman bungalows, mid-century tract homes, hillside properties, big retail and industrial zones, the right upgrade looks different from one door to the next.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar and our technicians work entirely from mobile service vehicles. There is no storefront to visit. We meet you at the door, look at what is actually installed, and recommend hardware that suits the door, the frame and the risk, rather than selling the most elaborate cylinder by default.

A high security lock is only as strong as the door around it. We look at strike plates, frame condition, hinge placement and door thickness as part of every job, because a pick-resistant cylinder on a weak frame is a false sense of safety. We will tell you honestly when a standard quality deadbolt is enough and when a restricted keyway is worth it.

How it works in Torrance

  1. 1

    Talk through your concerns

    Call (323) 997-8867 any hour. We ask what you are protecting, who has keys today, and whether you have had a break-in, a lost key or a former tenant or employee to worry about. That shapes the whole recommendation.

  2. 2

    Assess the door, frame and existing hardware

    On site, we check the door material, thickness, frame, strike and the lock currently installed. In Torrance that might be a 1960s Kwikset set on a tract-home door, an old mortise lock on a bungalow, or an aluminum storefront door.

  3. 3

    Choose the cylinder and key control level

    We explain the options: pick- and bump-resistant cylinders, drill-resistant hardened inserts, and restricted keyways where duplication is controlled. You decide how much key control you need, from household convenience to tracked key issuance for a business.

  4. 4

    Install and reinforce

    We fit the new locks, and where needed reinforce the strike, frame and hinge side so the door can actually resist force. We work to avoid unnecessary damage, especially on historic wood doors.

  5. 5

    Key setup and function test

    We cut and test your keys, make sure every lock operates smoothly, and can key multiple doors alike so you carry one key. We cover how to order additional keys under the restricted system.

  6. 6

    Walk-through and care advice

    Before leaving, we show you how the hardware works, how to keep it lubricated and aligned, and what to do if a key goes missing.

What affects the price

  • The grade and brand of cylinder chosen, and whether it carries a restricted keyway with controlled key duplication.
  • The number of doors and locks, and whether they are keyed alike or on a master-key system.
  • Door and frame condition, including whether strike plates, frames or hinges need reinforcement.
  • Door type, such as a historic wood door that needs careful prep, a metal door, or an aluminum storefront.
  • Whether the work is a scheduled visit or an after-hours or emergency call at night, on a weekend or on a holiday.
  • Additional hardware such as electronic or keypad options, closers or panic devices that tie into the upgrade.

Why Torrance chooses us

  • Fully mobile 24/7 service, so upgrades can happen after business hours or the same night as a break-in scare.
  • In business since 1987, with hands-on experience across everything from 1920s mortise sets to modern commercial hardware.
  • We assess the door and frame, not just the cylinder, so your high security lock is not undermined by a weak strike or frame.
  • Honest recommendations: we will say when a quality standard deadbolt does the job and when restricted keys are worth it.
  • Care for historic doors, including options to retrofit modern security without wrecking original wood and period character.
  • Key control guidance for landlords, retailers and facilities, including keyed-alike and master-key planning.

High Security Locks across Torrance

Torrance spans a lot of housing and building types, and each one calls for a different approach. In Old Torrance, around the El Prado historic district, 1910s and 1920s Craftsman bungalows often still carry original mortise locks and skeleton-key hardware. Owners usually want to keep the historic doors intact, so we look at rebuilding the mortise or discreetly adding a modern high security deadbolt that does not scar the original wood.

Further south and west, Southwood and West Torrance are filled with 1950s and 1960s ranch tract homes, many still running their original Kwikset or Schlage sets. After decades, those cylinders wear, and upgrading to a pick- and bump-resistant lock with a keyed-alike setup is a practical improvement for a family that wants one key for every door. The hillside homes of Walteria and Hollywood Riviera add mid-century and coastal properties where side gates, garage entries and sliding doors deserve as much attention as the front door. In ZIP 90505, for example, that often means a full-property plan rather than one lock.

Commercial work is just as common. Tenants near Del Amo Fashion Center and along Hawthorne Blvd, Sepulveda Blvd and Torrance Blvd may need restricted-key cylinders on aluminum storefront doors, along with service on closers and panic hardware, and much of that is done after closing. Industrial sites near the I-405 and I-110 corridors, and around Torrance Municipal Airport, often benefit from master-key systems with controlled key duplication. We serve ZIP codes 90501, 90502, 90503, 90504 and 90505, coming to you wherever you are.

High Security Locks in Torrance — FAQs

What makes a lock "high security"?
High security locks use tighter tolerances, hardened components and often restricted keyways to resist picking, bumping and drilling, plus controls on who can copy the key. Call (323) 997-8867 and we can explain which level fits your door.
Will a high security lock help if my door frame is weak?
Only partly. Force-based attacks often target the frame and strike, so we inspect and reinforce those when needed. The lock and door should be strong together.
Can you upgrade the locks on my historic Old Torrance bungalow without damaging the door?
Often yes. We can rebuild original mortise hardware or add a modern deadbolt in a way that respects the wood and period look. We assess the door first and explain the options before any drilling.
Can all my doors use one key?
Yes. We can key multiple high security locks alike, so a Southwood family, for example, can use one key throughout. Call (323) 997-8867 to plan it.
Do you handle storefront and commercial high security hardware?
Yes. We service aluminum-storefront cylinders, closers and panic hardware, and can set up master-key systems with restricted keys for retail and industrial sites in Torrance.
What does restricted key control mean in practice?
Keys can only be duplicated through authorized channels, so copies cannot be made at any hardware store kiosk. It is useful for landlords, businesses and anyone worried about unknown keys.
Can you come out at night or on weekends?
Yes, we are 24/7 and fully mobile. There is no shop to visit, because we come to your location in Torrance. Pricing for after-hours work depends on the factors we discuss when you call.
How much does a high security lock upgrade cost?
It depends on the cylinder grade, number of doors, key control level, door and frame condition, and timing. We talk through those factors and give you a clear quote before work begins.
