A standard builder-grade deadbolt keeps honest people honest, but it was never designed to resist someone who knows how to pick, bump or drill a lock. High security hardware is built differently: tighter tolerances, hardened steel inserts, security pins, restricted keyways and, in the better systems, key control so copies cannot be cut at just any hardware counter. For many Valley Glen households, that upgrade is a sensible, quiet improvement rather than an extreme one.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on practical advice. Sometimes the right answer is a high security cylinder in your existing door hardware. Sometimes it is a better deadbolt with a reinforced strike plate. And sometimes your current lock is fine and the weak point is the door frame. We will tell you which applies.

We are a fully mobile locksmith. There is no storefront to visit; we bring the hardware and tools to you, day or night, and do the work on site. That matters in a neighborhood like Valley Glen, where many people are juggling work, classes and family and cannot spend an afternoon shopping for locks.

How it works in Valley Glen

  1. 1

    Talk through your situation

    Call (323) 997-8867 and tell us about the door, the lock you have now, and what worries you: a recent break-in nearby, a tenant change, a home purchase, or simply old hardware. We will explain what to expect before anyone drives out.

  2. 2

    Inspect the door, frame and existing lock

    On site we look at more than the cylinder. We check the door thickness and condition, the strike plate, the screws and the frame, since a pick-resistant lock in a weak frame is a missed opportunity. On many 1940s-50s ranch homes, original frames and short strike screws are worth addressing.

  3. 3

    Choose the right level of protection

    We go over options such as pick-, bump- and drill-resistant cylinders, restricted keyways and key control, and how they fit with graded deadbolts or smart-lock hardware. You choose based on how you live, not on a sales script.

  4. 4

    Install and reinforce

    We install the lock, fit it cleanly to your door and add reinforcement where it helps, such as a longer-screw strike plate. Everything is tested so the bolt throws smoothly and the door closes properly.

  5. 5

    Cut and test keys, then walk you through it

    We provide your keys, confirm they operate the lock correctly, and explain how restricted keys work and how to order duplicates. If you have several exterior doors, we can discuss keying them alike so you carry one key.

What affects the price

  • The grade and type of lock chosen, since restricted-keyway and key-control systems differ in construction and cost from a basic upgraded deadbolt.
  • How many doors or cylinders are being upgraded, including whether you want them all keyed alike.
  • The condition of the door and frame, and whether reinforcement such as a new strike plate or door repair is needed.
  • Whether you are adding extra keys or a key-control card for duplicates, which depends on the system selected.
  • Whether the lock needs to work alongside smart-lock or electronic hardware.
  • The time of the call, as after-hours and emergency service differ from a scheduled daytime appointment.

High Security Locks across Valley Glen

Valley Glen sits between Van Nuys and North Hollywood, and much of it is made up of 1940s-50s ranch and traditional homes on tree-lined streets. Many of those doors still have original frames and hardware that has been rekeyed or swapped over decades. Around the Los Angeles Valley College district, we also see condos, apartments and student-adjacent rentals, where hardware gets heavy use and keys can end up in many hands. In those settings, a restricted-key high security lock gives landlords and owners more control over who can copy a key.

A common job here is a resale or move-in project: a 1950s ranch home near the college where every exterior lock is rekeyed alike and the front door gets a stronger deadbolt or smart lock. Another is a rental near campus where locks must change between occupants. We also help condo and townhome owners off Burbank Boulevard who are moving from a worn knob lock to a graded deadbolt, sometimes after a lockout. Along the Tujunga Wash and Great Wall corridor, homes back onto a quieter stretch where owners often want added peace of mind at side and rear doors.

We serve ZIP codes including 91401, 91405 and 91606, and travel along Burbank Boulevard, Victory Boulevard, Oxnard Street, Coldwater Canyon Avenue and CA-170. Whether you are near Valley Glen Community Park or closer to the campus, call (323) 997-8867 and we will come to you.

High Security Locks in Valley Glen — FAQs

What makes a lock high security?
A high security lock resists common attacks such as picking, bumping and drilling, using features like security pins, hardened inserts and tighter tolerances. Many also use restricted keyways so keys cannot be casually copied. Call (323) 997-8867 to discuss which type suits your door.
Do I need a high security lock for a Valley Glen home?
Not every home needs one. Valley Glen is a quiet residential area, but an upgrade makes sense after a break-in nearby, a move, a tenant change or if you simply want stronger protection. We will give an honest opinion about your door.
Will a high security lock help if my door frame is weak?
The lock is only part of the system. A weak frame or short strike screws can be the real vulnerability, especially on older ranch homes. We inspect the frame and strike and can reinforce them during the same visit.
Can you key all my exterior locks alike?
Yes. Keying exterior doors alike is popular for new owners and resale situations, so you carry one key. We can discuss doing it with high security cylinders. Call (323) 997-8867 to plan it.
Is this useful for rental properties near Los Angeles Valley College?
It can be. Restricted-key systems limit unauthorized duplication, which helps landlords when occupants change. We can also change or rekey locks between tenants. Pricing depends on the hardware and number of doors.
Do you have a shop I can visit?
No. We are fully mobile only, with no storefront. We bring the locks and tools to your home, condo or rental in Valley Glen and complete the installation on site.
Can high security locks work with a smart lock?
Often yes, depending on the products. Some setups pair a high security deadbolt with electronic hardware on another door, or use a smart lock with a strong mechanical backup. We will recommend what fits your door.
Are you available at night or on weekends?
Yes, we are available 24/7. If you are locked out or worried about security after a break-in, call (323) 997-8867 at any hour.
