Lock installation sounds simple until you stand in front of the actual door. In Sun Valley, that door might be a hollow-core slab on a modest postwar house, a steel man-door at the back of a warehouse, a chain-link yard gate behind San Fernando Road, or a solid original door on a 1920s stone home in Stonehurst. Each one calls for different hardware, different prep work, and a different idea of what 'secure' means.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are a fully mobile operation. There is no storefront to visit; we bring tools, hardware options and the know-how to your property, any hour of the day or night, every day of the year.

This page covers what a lock installation involves here in Sun Valley, how the work usually goes, what moves the price, and the local situations we see most: industrial yards and warehouses that need heavy-duty hardware, and older homes that deserve careful, sympathetic upgrades rather than a hole saw and a prayer.

How it works in Sun Valley

  1. 1

    Talk through the door and the goal

    When you call (323) 997-8867, we ask what the door or gate is, what it is made of, and what you want from the lock: basic privacy, real theft resistance, keyed-alike convenience, or controlled access for employees. For an industrial site we also ask about insurance requirements and who needs keys.

  2. 2

    Inspect the door, frame and surroundings on site

    A lock is only as strong as what holds it. We check door thickness, material, the strike area, hinges and the frame. A new deadbolt in a split frame or a thin door skin is a weak upgrade, so we tell you plainly if reinforcement should come first.

  3. 3

    Choose hardware that fits the situation

    We go over grades and styles with you. A yard gate near the San Fernando Road corridor may need a hardened padlock with a shielded shackle and a heavy hasp. A house may need a quality deadbolt and strike plate. Historic homes may call for finishes that suit the era.

  4. 4

    Prep and install cleanly

    We drill, bore and mortise with the right jigs so the bolt throws smoothly and the latch lines up. On a door that never had a lock, that means careful layout. Where possible we avoid unnecessary damage, especially on original wood doors.

  5. 5

    Reinforce the weak points

    Where it makes sense, we add a longer strike plate with long screws into the framing, a door edge reinforcer, or a better hasp on a gate. These small details usually decide whether a door holds up against a kick or a pry bar.

  6. 6

    Test, key and hand over

    We cycle every lock several times with the door open and closed, confirm the keys work smoothly, and show you how everything operates. If you have several doors, we can key them to work together so you carry fewer keys.

What affects the price

  • The type of door or gate: wood, steel, aluminum storefront, roll-up or chain-link all demand different prep and hardware.
  • Lock grade and style: a basic residential deadbolt differs from a high-security cylinder, a hardened padlock or a mortise lockset.
  • Whether the door needs new boring or modification, versus replacing an existing lock in a prepared opening.
  • The number of locks and whether they should be keyed alike or on a controlled key system for staff.
  • Reinforcement needs such as strike plates, frame repair, hasps or door edge guards.
  • Timing and location: after-hours or emergency calls, and how difficult the site is to reach, can affect the final quote.

Why Sun Valley chooses us

  • Fully mobile, 24/7: we come to the property, whether that is a home in Stonehurst or a yard off San Fernando Road, with no storefront detour.
  • Operating since 1987, with the owner, David Shar, leading the work, so experience with unusual doors and older hardware is built in.
  • Comfortable on both sides of the Sun Valley divide: residential deadbolts and heavy commercial gate and roll-up hardware.
  • Honest about the door: if the frame or door is the real problem, we say so rather than sell you a lock that will not hold.
  • Sympathetic work on older homes, choosing hardware and installation methods that respect original wood and period character.

Lock Installation across Sun Valley

Sun Valley is one of the more industrial parts of Los Angeles, tucked against the Verdugo Mountains and the flight paths of Hollywood Burbank Airport. Along San Fernando Road and the corridor behind the airport, warehouses, manufacturing shops, auto-dismantlers and recycling yards are everywhere, and most need locks that can take abuse. A yard that has just been hit by thieves often needs hardened padlocks, a sturdier gate lock and better man-door hardware, installed correctly so they actually resist cutting and prying. We work throughout ZIP code 91352 and can install on new doors or add locks where none existed.

It is a different story in the residential pockets. Many homes are modest, working-class postwar houses where a solid deadbolt and reinforced strike plate make a real difference. Then there is Stonehurst, with its 1920s stone and clinker-brick houses and original hardware. Cutting into an old door for a modern deadbolt takes care, and we aim for a clean, sympathetic upgrade that keeps the home's character while improving security.

Whether you are near the Stonehurst Recreation Center, up toward La Tuna Canyon, or off Glenoaks Boulevard, Sunland Boulevard, Vineland Avenue, I-5 or CA-170, we come to you. Call (323) 997-8867 and we will talk through what your door, gate or building needs.

Lock Installation in Sun Valley — FAQs

Can you install a lock on a door that never had one?
Yes. That is a core part of lock installation. We lay out and bore the door for the lock and latch, then fit the strike in the frame. Call (323) 997-8867 and describe the door so we can bring suitable hardware.
Do you install locks for warehouses and yards in Sun Valley?
Yes. We handle man-doors, roll-up door locks, gate locks and hardened padlocks for the industrial properties along San Fernando Road and near the airport corridor, along with residential work.
Are you available at night or on weekends?
We are available 24/7. If a break-in has left a door or gate unsecured, call (323) 997-8867 any time and we will work out the right fix.
Can you add a deadbolt to my historic Stonehurst home without ruining the door?
We take a careful approach with older doors: precise drilling, hardware that suits the period, and minimal damage to original wood. We will also check whether the frame needs reinforcement.
Do I need to come to a shop to pick out locks?
No. We are fully mobile and have no storefront. We bring options to your property and recommend what fits your door and security needs.
Can all my doors use the same key?
Usually yes. We can install locks keyed alike so one key works for several doors, which is useful for homeowners and for businesses managing staff.
How much will a lock installation cost?
It depends on the door material, lock grade, any modification the door needs, the number of locks and reinforcement. Describe your situation when you call (323) 997-8867 and we will explain what drives the quote.
Will a new lock fix a weak door frame?
Not by itself. A strong lock in a weak frame can still fail. We inspect the frame and strike area and can add reinforcement so the whole assembly holds up.
