Lock installation is different from a lockout or a rekey. You are starting from a door that has no hardware, a new door that needs to be prepared, or an opening that was never secured. Done well, the lock sits square in the door, the bolt throws cleanly into the strike, and the key works smoothly for years. Done poorly, it binds in humid weather, wobbles, or leaves a weak spot in the frame.

Arcadia has plenty of reasons to need new hardware. Older ranch homes in neighborhoods like Upper Rancho, Lower Rancho and Highland Oaks are regularly torn down and replaced with large custom houses, and each new build needs a full set of locks for entry doors, side gates, garage service doors and interior rooms. Condos and apartments near Santa Anita and Huntington Drive have their own needs, and commercial tenant spaces around the mall need dependable cylinders on storefront and back doors.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar leads the work. We are mobile only, with no storefront to visit. We bring the tools and hardware to your door, look at what you have, and install the lock that actually suits it.

How it works in Arcadia

  1. 1

    Tell us about the door and the goal

    Call (323) 997-8867 and describe what you are securing: a front entry, a patio slider, a side gate, an interior office door, or a whole new house. Tell us whether it is new construction, a replacement of something missing, or an added layer of security. That lets us plan the right hardware before we drive out.

  2. 2

    Inspect the door, frame, and strike area

    On site, we check the door material, thickness, and condition, plus the frame and where the strike plate will sit. Solid wood, hollow-core, metal, and fiberglass doors each take a lock differently. If the frame is cracked or too thin, we tell you so before drilling anything.

  3. 3

    Choose hardware that fits your use

    We talk through deadbolts, knob or lever sets, keyed-alike options, and master-key systems for homes or tenant spaces with several doors. For a new custom home, we can plan keying so one key works the doors you want and not the ones you do not.

  4. 4

    Prepare the door and install the lock

    We mark and bore the door to the correct backset, cut the latch and bolt mortises, and set the lock square. The strike plate is installed with screws long enough to reach the framing, not just the thin trim, which matters for kick-in resistance.

  5. 5

    Test, key, and hand over

    We cycle every lock several times with the door open and closed, check alignment, and confirm each key works. You get your keys and clear notes on how the system is set up, in case you add doors later.

What affects the price

  • The number of doors or openings, since a single deadbolt is a very different job than a full set for a new house.
  • The grade and type of hardware you choose, from standard residential deadbolts to higher-security or commercial-grade cylinders.
  • Door and frame condition, including whether boring a new door, reinforcing a thin frame, or repairing damaged wood is needed.
  • Keying complexity, such as keyed-alike sets or a master-key system with several levels of access.
  • Door material, because metal, fiberglass, and solid-core doors take more time and tooling than a basic hollow door.
  • Timing and access, including after-hours or weekend requests and how easy it is to reach the doors.

Why Arcadia chooses us

  • Fully mobile service: we come to the property with tools and hardware, and there is no storefront you have to visit.
  • Available 24/7, so a door left unsecured after a late contractor handoff or a break-in attempt does not have to wait.
  • In business since 1987, with owner David Shar leading the work and a long history across Greater Los Angeles.
  • Master-key and keyed-alike planning for new builds and multi-door properties, so access is organized from day one.
  • We inspect the frame and strike area first and tell you honestly if reinforcement is worth doing, rather than just bolting hardware onto a weak door.
  • We handle residential and commercial installs, from custom homes to condo units and shopping center tenant spaces.

Lock Installation across Arcadia

Arcadia's housing market shapes the lock work we see. In Upper Rancho, Lower Rancho, and Highland Oaks, 1950s and 1960s ranch homes are frequently replaced with large new custom estates. A new build in ZIP 91006 or 91007 can mean a full lockset package: front entry, rear doors, garage service door, pool or guest-house doors, and a master-key system so the owners, family, and any property manager have the right level of access.

Closer to Santa Anita and along Huntington Drive, condos and apartments call for a different approach. Tenants and owners may need a new deadbolt on a door that never had one, added security on a patio slider, or a fresh install paired with a rekey on move-in. Neighborhoods like Baldwin Stocker and Peacock Village have their own mix of homes and older doors, and we match the hardware to what is actually there. Properties in ZIP 91066 and 91077 get the same careful inspection.

On the commercial side, strip centers and tenant spaces near Westfield Santa Anita often need new cylinders or locks on storefront, back-of-house, and storage doors. Whether you are off Baldwin Ave, Santa Anita Ave, or near the I-210 and SR-19, call (323) 997-8867 and we will come to you.

Lock Installation in Arcadia — FAQs

What is the difference between lock installation and rekeying?
Installation puts a new lock on a door that has none or on a newly prepared door. Rekeying changes the internal pins of an existing lock so old keys stop working. Many Arcadia move-ins need both. Call (323) 997-8867 to describe your door.
Can you install locks on a brand-new home in Upper Rancho or Highland Oaks?
Yes. We supply and install locksets for new construction and can set up keyed-alike or master-key systems. Tell us how many doors there are and who needs access to which ones.
Do you install locks at night or on weekends?
Yes, we are available 24/7 and fully mobile. If a door needs to be secured after hours, call (323) 997-8867 and we will talk through the situation.
Can you add a deadbolt to a door that only has a knob lock?
Usually, yes. We check the door thickness and edge first, then bore for the deadbolt and reinforce the strike area. Some very thin or damaged doors may need repair or replacement.
What is a master-key system and do I need one?
It lets different keys open different sets of doors, with one master key opening all. It is useful for large custom homes, rental properties, and commercial tenant spaces. We can help you decide if it fits.
Do you install locks for businesses near Westfield Santa Anita?
Yes. We install and service locks and cylinders for storefront, back, and storage doors in shopping center tenant spaces. Call (323) 997-8867 to discuss your setup.
Can I provide my own lock hardware?
Often yes, as long as it suits the door. We will check that it fits and is appropriate before installing. If it is not a good match, we will explain why and suggest alternatives.
Do I need to visit a shop to arrange this?
No. Crenshaw Lock Company is mobile only. We come to your Arcadia home, condo, or business, so there is no storefront trip involved.
