Installing a lock sounds simple until you are standing at a door that has no bore, a frame that has been painted over six times, or a brand new smart lock that does not fit the prep. Azusa has all of those situations. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has seen how different the doors can be from one neighborhood to the next.

Our lock installation service covers fresh installs: a new entry door, a gate, a side door or garage service door that never had a lock, a room addition, or a home that needs better hardware where only a knob existed. We handle deadbolts, keyed entry sets, mortise locks, multipoint hardware and smart locks, and we fit them so the bolt throws cleanly into a properly reinforced strike.

We are fully mobile. There is no storefront to visit, so you never have to carry a door anywhere. We work at your property, day or night, and we explain what we are doing and why before we drill anything.

How it works in Azusa

  1. 1

    Tell us about the door

    Call (323) 997-8867 and describe the door: material, thickness, whether it is new or existing, and what you want it to do. A hollow-core bedroom door, a solid wood bungalow door and a fiberglass foothill entry each need different hardware, so this call shapes the job.

  2. 2

    We come to you

    Because we are 24/7 and fully mobile, a technician drives to your Azusa address with a range of deadbolts, handlesets, strikes and installation tools. Nothing needs to be ordered unless your door calls for something unusual, such as a particular mortise body.

  3. 3

    Inspect the door and frame

    Before cutting anything, we check door thickness, edge condition, frame strength and alignment. A strong lock in a weak frame is only half a solution, so we note whether the jamb needs reinforcing.

  4. 4

    Prepare and install

    We mark and bore the door with proper templates, cut the latch and strike mortises cleanly, and mount the lock. On frames that need it, we use a longer strike screws and reinforcement so the bolt bites into the structure and not just the trim.

  5. 5

    Test and key setup

    We operate the lock repeatedly with the door open and closed, check the throw and alignment, and make sure keys work smoothly. For smart locks we pair the device, confirm the settings, and show you how everything works.

  6. 6

    Walk-through and care tips

    We hand over keys, explain how to maintain the hardware, and point out any other doors where a quick upgrade would help. You leave knowing exactly what was installed.

What affects the price

  • The type of lock: a basic keyed deadbolt, a high-security cylinder, a mortise set and a smart lock sit at very different points in cost.
  • Whether the door is already prepped. A door with existing bores is quicker than one that needs new holes cut from scratch.
  • Door material and condition: solid wood, steel, fiberglass and aged historic doors each take different tools and care.
  • Frame and strike reinforcement, which may be needed if the jamb is thin, split or worn.
  • The number of locks and whether they should be keyed alike so one key opens several doors.
  • The hour and location of the call, since after-hours mobile service involves different scheduling than a planned daytime appointment.

Why Azusa chooses us

  • Serving the region since 1987, so older door types like original mortise setups on 1920s bungalows are familiar territory, not a surprise.
  • Fully mobile and available 24/7, with the work done at your door rather than at a shop counter.
  • Owner-led: David Shar stands behind the work, and we explain what we are doing in plain language.
  • We pay attention to the frame and strike, not just the lock body, because that is where many break-ins actually succeed.
  • Comfortable with both traditional hardware and newer smart-lock and multipoint systems, so we can recommend what fits your door rather than push one product.
  • We do not quote by guesswork. We look at the door and tell you honestly what it needs.

Lock Installation across Azusa

Azusa is a layered city, and lock installation here changes depending on where you live. Downtown Azusa along Azusa Ave and Foothill Blvd, the old Route 66 corridor, has 1900s to 1920s bungalows and brick commercial buildings, some with original mortise hardware. Installing a lock there often means working with thick old wood, unusual prep, and the character of the door, so we fit new hardware without butchering the original. If you are in ZIP code 91702 near downtown, we can help you add security while keeping the charm.

On the other side of town, Rosedale is a 2010s master-planned community in the foothills, where new construction often arrives with smart-lock-ready doors. Homeowners there tend to want a smart lock added to a side or garage entry, or a multipoint system upgraded on a main door. Further up at the canyon mouth, gated Mountain Cove has its own access concerns, and a solid deadbolt on every exterior door remains a sensible layer behind the gate.

Azusa also has post-war tract homes and student-rental housing near Azusa Pacific University and Citrus College, where landlords and tenants may want added locks on bedroom doors, side gates or newly converted spaces. Whether you are off the I-210 at Azusa Ave, near the Metro A Line station, up Gladstone St or Alosta Ave, or heading toward San Gabriel Canyon on SR-39, we come to you. Call (323) 997-8867.

Lock Installation in Azusa — FAQs

Can you install a lock where there has never been one?
Yes. We can bore a new door, cut the latch and strike mortises, and fit a deadbolt or handleset on a door that never had hardware. Call (323) 997-8867 and describe the door so we bring the right tools.
Do you install smart locks on newer Rosedale homes?
Yes. Many newer homes in Rosedale and similar developments are prepped for smart locks. We install and pair them, check that the bolt aligns well, and show you how the settings work.
Can you work on the old mortise locks in downtown Azusa bungalows?
We can install, service or upgrade mortise hardware common on 1900s to 1920s doors. We aim to preserve the door while improving its security, and we will tell you honestly if a part needs special sourcing.
Is lock installation available at night or on weekends?
Yes. We are 24/7 and fully mobile. Call (323) 997-8867 any time and we will talk through the work.
Do I need to bring the door or visit a shop?
No. We have no storefront. Everything happens at your property in Azusa, so there is nothing to carry or drop off.
How is the price of installation decided?
It depends on the lock type, door material, whether the door is already prepped, frame reinforcement, number of locks and the time of the call. We assess the door and explain the work before starting.
Can you key several new locks alike?
Yes. We can set multiple new locks to the same key, which is handy for a house with front, side and garage doors, or for a landlord managing a property near APU.
Should I reinforce the door frame too?
Often it is worth it. A strong deadbolt only helps if the strike and jamb can take force. We check the frame during installation and recommend reinforcement when it is weak.
