A standard pin-tumbler deadbolt is fine for keeping honest people honest, but it is not built to resist someone who knows how to pick it, bump it with a filed key, or drill it out. High security locks are designed differently. They use tighter tolerances, more complex or hardened internals, security pins that resist manipulation, hardened steel inserts that fight drilling, and keys that are restricted so they cannot be copied at a hardware-store kiosk. In Van Nuys, where a single day can take you from a quiet bungalow street to a busy commercial strip, that difference matters for very different reasons.

Van Nuys has a wide mix of buildings, and the right high security solution depends on which one you are in. A 1920s Spanish bungalow near Sylvan Park may have a mortise lockset and a period door you do not want to cut up. A 1950s tract home in Kester Ridge usually has a standard bored door prep that accepts a high security deadbolt cleanly. An aluminum-storefront shop on Van Nuys Boulevard or Sepulveda Boulevard has narrow stiles, Adams Rite style hardware and different needs altogether. We look at the door first and then recommend hardware, rather than selling one product for everything.

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 the work happens at your door. This page explains how an installation goes, what affects the cost, and what is specific to securing property in Van Nuys.

How it works in Van Nuys

  1. 1

    Talk through the threat and the door

    Call (323) 997-8867 and tell us what you are protecting and why. A landlord worried about lost tenant keys needs something different from a business owner worried about forced entry, or a homeowner who wants keys that cannot be duplicated. We ask about the door material, the existing hardware and who currently holds keys.

  2. 2

    On-site assessment

    Because we are mobile, the technician examines the actual door, frame, strike and surrounding hardware at your property. Weak points often sit outside the lock itself: a short strike screw, a thin jamb, a gap at the latch, or a glass panel within arm's reach of the thumb turn. We point these out honestly, including when a lock upgrade alone will not solve the problem.

  3. 3

    Choose the right hardware

    We explain the options in plain language: restricted keyways with patent-protected key control, pick- and bump-resistant cylinders, hardened drill-resistant inserts, and the grades of deadbolt body and strike. For a vintage mortise door, we discuss whether a high security cylinder can fit the existing mortise body or whether another approach protects the door better.

  4. 4

    Installation and fitting

    We install the lock, reinforce the strike or jamb where needed and confirm the bolt throws smoothly into solid framing. On older doors we work carefully to preserve original wood and finish. On commercial aluminum doors we match the cylinder to the existing deadlatch or panic hardware.

  5. 5

    Key control and handoff

    We test every key, confirm the lock operates cleanly from both sides and explain how restricted key duplication works, including who can authorize additional keys. For multi-unit or business setups, we talk through key records so you can manage who has access over time.

What affects the price

  • The type of lock: a single high security deadbolt costs differently than a full set of cylinders, a mortise upgrade or a keyed-alike or master-keyed system.
  • The level of key control: restricted keyways with patent protection and authorization cards involve different components than a basic upgraded cylinder.
  • The condition of the door and frame: reinforcing a weak jamb, replacing a strike or addressing a worn door prep adds parts and labor.
  • The number of doors and keys: a multi-unit apartment building or commercial property with several entrances differs from a single front door.
  • Door type and compatibility: vintage mortise, aluminum storefront, steel commercial and residential wood doors each need different hardware and fitting time.
  • The time of the call: 24/7 service means after-hours and urgent requests can be priced differently from scheduled daytime work.

Why Van Nuys chooses us

  • Fully mobile since 1987: the technician comes to your door in Van Nuys and works from the real conditions, not a catalog photo.
  • Door-first advice: we check the strike, jamb and surrounding hardware, not just the cylinder, and tell you honestly if a cheaper fix is enough.
  • Experience across Van Nuys building types: period mortise locks, tract-home deadbolts, apartment master-keying and aluminum-storefront commercial hardware.
  • Respect for original doors: we aim to upgrade security without cutting up a period door on a Sylvan Park bungalow.
  • Clear key-control explanation: you understand who can copy your keys and how to authorize more before we leave.
  • Available 24/7: if a break-in damages a lock or a tenant leaves with keys, you can call (323) 997-8867 any hour.

High Security Locks across Van Nuys

Van Nuys is a central San Fernando Valley community with an unusually varied building stock, and that shapes what high security looks like here. Around the original townsite near Sylvan Park, many 1920s to 1940s Spanish and California bungalows still carry vintage mortise locksets and original doors. Owners there often want better protection without losing the character of the entry, so we focus on fitting suitable high security cylinders and reinforcing the frame carefully. In the 1950s tracts of Kester Ridge, standard bored doors usually accept a high security deadbolt neatly, and the main upgrade questions are key control and strike reinforcement.

Around the Van Nuys Civic Center and Government Center, with the Valley Municipal Building and the Van Nuys Courthouse nearby, offices, legal services and small businesses cluster on aluminum-storefront buildings. These often use Adams Rite style deadlatches and panic hardware, and a tenant change is a common moment to upgrade to restricted keys so former occupants cannot keep working copies. Dense apartment corridors along Sepulveda Boulevard, Van Nuys Boulevard and Victory Boulevard raise a different issue: managing keys across many units and many residents over time.

We serve ZIP codes including 91401, 91405, 91406 and 91411, from Sherman Way up to the Sepulveda Basin edge, and from the I-405 to the US-101 corridors. Around Van Nuys Airport, aviation-adjacent industrial and hangar-area businesses have their own needs for controlled keys and durable commercial hardware. Wherever you are, call (323) 997-8867 and we will come to you.

High Security Locks in Van Nuys — FAQs

What makes a lock high security?
High security locks resist common attacks such as picking, bumping and drilling through tighter tolerances, security pins, hardened inserts and restricted keyways. Many also control key duplication. Call (323) 997-8867 to discuss which features fit your door.
Can you install high security locks on a 1920s bungalow near Sylvan Park?
Often yes. We look at whether a high security cylinder can work with the existing mortise body or whether another solution protects the door better, while keeping the original door intact as much as possible.
Will a high security lock protect me if my door frame is weak?
Not fully. A strong lock in a weak jamb can still be forced. We inspect the strike, screws and frame and recommend reinforcement where it is needed.
What are restricted keys and why do they matter for landlords?
Restricted keys can only be duplicated with proper authorization, so tenants or former employees cannot easily make extra copies. This helps landlords and property managers in Van Nuys apartments keep track of access.
Can you upgrade the Adams Rite deadlatch on my storefront?
Yes. We can fit suitable cylinders to aluminum-storefront deadlatches and panic hardware, and rekey them to restricted keys after a tenant change. Call (323) 997-8867 to describe your door.
Do I need a new lock if I just lost a key?
Not always. Rekeying may be enough, but if you want stronger protection or key control at the same time, upgrading to a high security cylinder can be a sensible step.
Do you offer emergency service for damaged locks?
Yes. We are mobile and available 24/7, so if a forced entry damages your lock, you can call (323) 997-8867 at any hour and we will help secure the door.
Do you have a shop I can visit?
No. Crenshaw Lock Company is fully mobile, so we come to your home or business anywhere we serve in Van Nuys and the surrounding area.
