Altadena's commercial picture looks different from most of Los Angeles County right now. Along Lake Ave, Lincoln Ave, and Fair Oaks Ave you will find small shops, offices, studios, and service businesses, and across the foothills a large amount of rebuilding is under way after the January 2025 Eaton Fire. Locks, keys, and access control sit at the center of all of it: a new build needs fresh hardware, a contractor needs a secure site, and a surviving business may be dealing with doors that no longer work the way they should.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar built the business around being fully mobile. There is no storefront to visit. We drive to you, whether that is a commercial space on Lake Ave, a rebuild lot off Altadena Dr, or a workshop tucked into a side street, and we do the work on site. We are available around the clock, so a lockout or a broken door at night is not something that has to wait for morning.

Our commercial work covers rekeying after staff changes, installing and servicing deadbolts and panic hardware, setting up master-key systems, handling storefront and glass-door locks, working on gates and side-yard locks, and securing construction sites with contractor lockboxes. We explain what we find and what the options are before we start, so you can decide what makes sense for your building and budget.

How it works in Altadena

  1. 1

    Call and describe the situation

    Call (323) 997-8867 any hour. Tell us what kind of building it is, what the doors and locks are doing, and whether this is an emergency or planned work. A few specifics let us bring the right hardware and tools.

  2. 2

    We come to your location

    Because we are fully mobile, the work happens at your door. That might be a storefront, an office suite, a warehouse roll-up entrance, or a bare jobsite where the framing is still going up.

  3. 3

    Assess the doors, hardware, and risks

    We look at what is installed, how it is holding up, who has keys, and where the vulnerabilities are. On surviving buildings we check for heat or soot damage to cylinders, latches, and strike plates.

  4. 4

    Review options before work begins

    We lay out the realistic choices, such as repair versus replacement, rekeying versus new hardware, or a simple master-key layout versus individual keys, so you understand the tradeoffs before anything is done.

  5. 5

    Do the work and test every lock

    We install, rekey, or repair, then test each lock and key under real use. For master-key systems we confirm each key opens only what it should.

  6. 6

    Hand over keys and document the setup

    You get all the keys cut, a clear explanation of how the system is organized, and guidance on tracking who holds which key so future changes are easy to manage.

What affects the price

  • Whether the job is an emergency lockout or planned work, and what hour of day or night the call comes in.
  • The type of hardware involved, such as standard deadbolts, commercial-grade grade-1 locks, panic bars, or electronic access.
  • The number of doors, cylinders, and gates being rekeyed, installed, or keyed into a master-key system.
  • The condition of existing hardware, especially heat- or soot-damaged cylinders that must be freed, repaired, or replaced.
  • The complexity of a master-key layout, including how many levels of access you need and how many keys must be cut.
  • Site conditions, such as a construction site with no finished doors, hillside access, or large lots with multiple gates.

Why Altadena chooses us

  • Fully mobile and available 24/7, so we handle commercial calls at your site rather than asking you to bring anything to a shop.
  • In business since 1987, with David Shar as owner and lead tech, so the experience behind the work is long and local.
  • Familiar with the post-fire reality in Altadena, including new-construction keying, contractor lockboxes, and soot-seized hardware.
  • We explain the options plainly and do not push replacement when a repair or rekey will serve you well.
  • We build master-key systems that stay simple enough to manage, which suits small businesses and rebuild projects alike.
  • We cover both the building and its perimeter, including gates, side-yard locks, and outbuildings on larger lots.

Commercial Locksmith across Altadena

Altadena's building stock runs from 1910s to 1940s Craftsman bungalows and Spanish Colonial homes, many in the Janes Village tract, to mid-century buildings and now a growing number of new rebuilds. In ZIP code 91001, which stretches across the area west and north of Lake Ave, and in 91003 toward Fair Oaks Ave and Woodbury Rd, the commercial need has shifted toward getting properties secured and operating again. Contractors on rebuild lots need lockboxes and controlled access during construction, and owners who finish a build need all-new locksets with a simple master-key system.

Surviving properties have their own issues. In Janes Village, months of ash and smoke exposure have left some deadbolts and cylinders seized, and freeing or rekeying them often saves hardware that would otherwise need replacing. Home-based businesses and small offices in these older structures also benefit from a fresh key setup so that nobody from the construction, cleanup, or prior-ownership period still holds a working key.

We also work in the hillside areas near Christmas Tree Lane on Santa Rosa Avenue, around the Altadena Country Club, and in The Meadows, where larger lots often mean gates, side-yard locks, and detached structures that need the same attention as the main door. Whether we are meeting you near Charles White Park, Farnsworth Park, or on a lot with a view toward the Cobb Estate and Mount Lowe Railway site, we bring the work to you, any hour, at (323) 997-8867.

Commercial Locksmith in Altadena — FAQs

Do you offer commercial locksmith service in Altadena at night?
Yes. We are available 24/7 and fully mobile, so you can call (323) 997-8867 at any hour for a lockout, a broken lock, or a security concern at your business.
Can you set up locks and a master-key system on an Eaton Fire rebuild?
Yes. We supply and key all-new locksets and can set up a simple master-key system, so the owner, builder, and any managers have the access they need and nothing more.
How do you secure a construction jobsite?
We set contractor lockboxes so authorized crews can get in while the site stays controlled. We can also rekey or change locks once the building is finished so construction-era keys stop working.
Do you have a shop I can visit?
No. We are mobile only, with no storefront. We come to your business, home, or jobsite anywhere in Altadena, and you can reach us at (323) 997-8867.
Can seized deadbolts be saved after smoke and soot exposure?
Often, yes. We assess whether a cylinder can be freed, cleaned, and rekeyed or whether it should be replaced. The decision depends on how much heat and ash damage the hardware has taken.
Do you handle gates and side-yard locks on larger properties?
Yes. On bigger lots near Christmas Tree Lane or the Country Club, we can rekey or install locks on gates, side yards, and outbuildings along with the main doors.
What affects the cost of commercial lock work?
The main factors are the number of doors, the type of hardware, the condition of existing locks, how complex a master-key system is, and the time of the call. We review these with you before starting.
Should I rekey after buying or taking over a space?
Yes, it is a smart first step. Rekeying makes sure previous owners, tenants, or contractors cannot use old keys. Call (323) 997-8867 to schedule it.
