Most homes in West Hills were built between the 1960s and 1980s, and a lot of them still carry the original builder-grade Kwikset or Schlage hardware. Those locks did their job for decades, but the pins, springs and latches are wearing out, and the basic cylinders inside them can be picked, bumped or drilled by someone with the right know-how. A high security lock replaces that weak point with a cylinder built to resist those methods.

High security hardware is more than a stronger-looking deadbolt. The real differences are inside: tighter tolerances, hardened inserts that frustrate drilling, pin designs that resist picking and bumping, and in many systems a restricted keyway, meaning copies can only be made with authorization rather than at any hardware-store kiosk. That last point matters in a neighborhood where houses change hands, contractors come and go, and old keys float around for years.

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, so every job happens at your property. We look at the door, the frame, the strike and the way you actually live, then recommend hardware that fits rather than selling the most expensive option by default.

How it works in West Hills

  1. 1

    Talk through what you want to protect

    Call (323) 997-8867 and tell us about the doors in question: front entry, garage-to-house door, side gates, or a pedestrian gate in a community. We ask about your current locks, who has keys, and whether you also want smart-lock features, so we arrive with the right options.

  2. 2

    Inspect the door, frame and strike

    A strong cylinder can't make up for a weak frame. We check door thickness, bore holes, the strike plate, the screws that anchor it, and whether the door has settled over the years. On older tract homes, worn latches and loose strikes are common and are worth fixing at the same visit.

  3. 3

    Choose the right level of hardware

    We explain the options in plain terms: pick- and bump-resistant cylinders, drill-resistant hardened components, and restricted keyway systems with controlled key duplication. You decide how much protection suits the door and your budget.

  4. 4

    Install and align everything

    We remove the old hardware, fit the new deadbolt or cylinder, reinforce the strike where needed, and make sure the bolt throws smoothly into the frame. A high security lock that binds is a lock people stop using, so alignment is part of the job.

  5. 5

    Cut and test keys, then walk you through it

    We cut your keys, test them in each lock, and explain how the restricted key system works, including how to request additional copies. If several doors are being done, we can key them alike so one key handles the house.

What affects the price

  • The grade and brand of lock chosen, since restricted-keyway and drill-resistant systems differ in construction and cost.
  • How many doors or gates are being upgraded, and whether they are being keyed alike to a single key.
  • The condition of the door and frame, including whether the strike, latch bore or door edge needs reinforcement.
  • Whether you want smart-lock or electronic features layered on top of a high security cylinder.
  • The number of keys you need and any restricted or authorized-only duplication cards that come with the system.
  • Time of day and urgency, such as a late-night service call after a break-in attempt versus a scheduled daytime upgrade.

Why West Hills chooses us

  • Fully mobile and available 24/7, so upgrades and emergency lock changes happen at your home with no trip to a shop.
  • In business since 1987, with the owner, David Shar, leading the work rather than handing it off.
  • We assess the door and frame first, because the best cylinder is wasted in a loose or split frame.
  • We understand local housing, from 1970s tract homes with aging builder hardware to hillside properties and gated communities.
  • We explain trade-offs honestly, including when a mid-level upgrade is enough and when higher security is worth it.
  • We can match gate locks, deadbolts and keys so one system covers the whole property.

High Security Locks across West Hills

West Hills sits at the western edge of the San Fernando Valley, and its housing reflects that. Around the Shadow Ranch area, many homes are 1960s to 1980s tract houses that are on their second or third owner. New owners often want every exterior door rekeyed to one key and a better deadbolt at the front, and a high security cylinder is a natural starting point since nobody knows how many old keys exist. Over in the Platt Village and Platt Ave corridor, we see the same aging Kwikset and Schlage hardware wearing out, along with garage-to-house doors where a failed deadbolt can jam shut and require careful drilling and replacement.

Towards the Valley Circle foothills and the Bell Canyon edge, homes are larger, more private and often sit inside gated developments. A lost key there can affect more than the front door, because the pedestrian gate lock and the house deadbolt may need to be matched again. Properties backing up to the Santa Susana foothills and the Upper Las Virgenes Canyon Open Space Preserve also tend to feel more isolated, which is a good reason to invest in drill- and pick-resistant hardware on the doors that face the street and the yard.

We serve ZIP codes 91307, 91304 and 91308, from the streets near Shadow Ranch Park and Orcutt Ranch Horticultural Center to homes along Fallbrook Ave, Platt Ave, Roscoe Blvd, Victory Blvd and Valley Circle Blvd. Because we are mobile only, we come to wherever you are in West Hills, whether that is a home near West Hills Hospital & Medical Center or a family house close to Chaminade College Preparatory.

High Security Locks in West Hills — FAQs

What makes a lock "high security"?
It is built to resist common attacks such as picking, bumping and drilling, usually with tighter tolerances, hardened inserts and specialized pin designs. Many also use restricted keyways so keys cannot be copied freely. Call (323) 997-8867 and we can talk through options for your doors.
Is my older West Hills tract home a good candidate for an upgrade?
Yes. Homes built from the 1960s to the 1980s often still have original builder-grade hardware that is wearing out. We check the door and frame first, then upgrade the cylinder, deadbolt and strike as needed.
Can you key all my doors the same?
Yes. We can rekey or replace locks so every exterior door works with one key. This is common for new owners near Shadow Ranch who do not know who holds old keys.
What is a restricted key?
A restricted key uses a keyway that is protected, so copies are generally made only with authorization instead of at any key kiosk. That helps you control who has access over time.
Can you match a gate lock to my house key?
In many cases, yes. For gated communities off Valley Circle, we can often match a pedestrian gate lock and the front deadbolt so one key works. Call (323) 997-8867 so we can plan around your specific hardware.
Can a high security lock be combined with a smart lock?
Often yes. Many homeowners keep a strong mechanical cylinder and add smart features, or choose a smart deadbolt with a quality cylinder. We will explain what works with your door.
What if my garage-to-house deadbolt is jammed?
We can assess the lock and, if needed, drill or extract it and install a replacement. We also check the strike and door alignment so it does not fail again.
Do you have a shop I can visit?
No. Crenshaw Lock Company is fully mobile, so we come to your home anywhere in West Hills, 24/7.
