A standard builder-grade deadbolt does its job on a quiet street, but it was never designed to resist someone who knows how to pick, bump or drill a cylinder. High security locks are built differently. They use tighter tolerances, more complex pin or sidebar mechanisms, hardened inserts that frustrate drilling, and keys that cannot be copied at a kiosk. In Thousand Oaks, where homes range from 1960s ranch houses to gated hillside estates, the right upgrade depends a great deal on the door, the frame and the people who use it.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar and our team bring that experience to every installation. We are a mobile-only service. There is no storefront to visit; we bring the hardware and tools to your property, look at the door in person, and recommend what actually makes sense rather than selling the most expensive cylinder on the truck.

This page explains how a high security lock project typically works in the Conejo Valley, what affects the cost, how restricted keys protect you, and what to ask before you commit. If you would rather talk it through, call (323) 997-8867 any time of day or night.

How it works in Thousand Oaks

  1. 1

    Talk through your goals and your doors

    We start by asking what you are protecting and why. A homeowner worried about key duplication has different needs than a tenant managing many employees. We ask about every exterior door, the garage entry, side gates and any current lock brands, so the recommendation covers the whole picture.

  2. 2

    On-site inspection of the door and frame

    A strong cylinder in a weak door is still a weak door. When we arrive, we check the door material, the strike plate, the screws, the frame and the latch alignment. Many Thousand Oaks homes have short strike screws or worn frames that matter as much as the lock itself.

  3. 3

    Choose the right system

    We explain the options in plain language: high-security cylinders with restricted keyways, multipoint locks common on European-style doors, and keyed-alike or master-keyed arrangements for several doors. You decide how much key control you want, including whether duplicates must be authorized through a card or registration process.

  4. 4

    Installation and fitting

    We install the new cylinders or hardware, reinforce strike plates when needed, and confirm the bolt throws smoothly without binding. Doors that have settled or swelled over the years sometimes need adjustment so the lock works as designed.

  5. 5

    Key issuing, testing and handover

    We test every key on every lock, review which keys are restricted, and explain how to order additional copies safely. We also walk through any follow-up we suggest, such as upgrading a garage entry door or a gate latch.

What affects the price

  • The lock series you choose: restricted-keyway cylinders with patented key control differ in cost from basic high-security upgrades.
  • The number of cylinders and doors, including garage entry, side doors, gates and any outbuildings.
  • Door and frame condition: strike reinforcement, adjusting a sagging door or replacing worn hardware adds labor and parts.
  • Key quantity and control: extra keys, keyed-alike sets and master-key hierarchies affect pricing.
  • Hardware type: multipoint systems, smart-lock integration or specialty mortise cylinders require different parts and time.
  • Timing and location: after-hours or urgent calls may be priced differently than scheduled appointments, and we confirm before work begins.

Why Thousand Oaks chooses us

  • Fully mobile: we bring the hardware to your door and do the work on site, so there is no shop trip and no leaving your property unsecured.
  • In business since 1987, with owner David Shar directly involved in how we approach installations.
  • Door-first thinking: we inspect the frame, strike and latch, not just the cylinder, so the upgrade truly improves security.
  • Honest recommendations: if a standard quality deadbolt will serve a particular door, we say so instead of upselling.
  • Experience across residential and commercial work, from single-family rekeys to master-key planning for multi-suite offices.
  • Available 24/7, so a lockout or a break-in repair can be handled at any hour with a lasting fix rather than a temporary one.

High Security Locks across Thousand Oaks

Thousand Oaks is a Conejo Valley city with a wide mix of housing, and the right high security setup changes from one neighborhood to the next. In Lynn Ranch and older central areas around 91360, many 1960s to 80s ranch and split-level homes still have original deadbolts and thin strike plates. A restricted-keyway cylinder paired with a reinforced strike is often the most meaningful upgrade there. In Newbury Park, including homes in 91320 and 91362, large tract developments mean many neighbors share the same door and lock layouts, which makes rekeying after a purchase especially worthwhile.

Further north and west, North Ranch and Dos Vientos Ranch have higher-end gated and custom estates where multipoint European-style locks, high-security cylinders, and gate and intercom systems are common. A typical project might be a high-security rekey using Medeco or Mul-T-Lock hardware while we also troubleshoot a gate or intercom that is not communicating with the entry. Hillside custom homes throughout the area often have heavy doors and unusual hardware, so on-site assessment matters.

Commercial needs are strong too. Business parks along Thousand Oaks Blvd and Rancho Conejo Blvd, near the biotech and office presence that includes the Amgen campus, drive demand for master-key systems and access control for multi-suite tenants. Whether you are near The Oaks mall, the Civic Arts Plaza, or just off US-101 or SR-23, we reach you wherever you are. Call (323) 997-8867 and we will come to you, any hour.

High Security Locks in Thousand Oaks — FAQs

What makes a lock high security instead of standard?
High security locks resist picking, bumping and drilling through tighter tolerances, more complex internal mechanisms and hardened components. Many also use restricted keys that cannot be duplicated without authorization. Call (323) 997-8867 to discuss which level suits your door.
Can you install high security locks at my Thousand Oaks home at night?
Yes. We are available 24/7 and fully mobile, so we can come to your property whenever you need us. For non-urgent upgrades, many people prefer a scheduled daytime visit so we can inspect all doors calmly.
Do you work with Medeco and Mul-T-Lock?
We install and rekey high-security systems including Medeco and Mul-T-Lock, depending on your door and needs. We will explain the key control differences before you choose.
Will a new lock help if my door frame is weak?
Not fully. A strong cylinder can still be defeated if the strike plate or frame fails. We inspect the door, frame and strike and reinforce them as part of the job where needed.
I just bought a home in Newbury Park. Should I rekey?
Rekeying after a purchase is a smart move because you cannot know who holds old keys. Upgrading to a restricted-key cylinder at the same time adds protection against copying. Call (323) 997-8867 to arrange a visit.
Can you set up a master-key system for an office or biotech suite?
Yes. We plan master-key hierarchies so tenants or departments have their own keys while management retains broader access. We also discuss access control options for larger spaces.
Can you help with gates and intercoms at North Ranch or Dos Vientos estates?
We can troubleshoot gate and intercom entry problems alongside lock upgrades, depending on the system. Describe the issue when you call and we will tell you what we can address on site.
How is the price determined?
Price depends on the lock series, number of doors, door and frame condition, key quantity and timing. We discuss the factors and confirm the approach before beginning work.
