Locks do not last forever. Springs weaken, latches stick, finishes wear through, and keys get copied so many times that nobody knows who holds one. In Azusa, where a 1920s bungalow can sit a few blocks from a 2010s foothill home, the right replacement depends heavily on what is already in the door.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and our owner and lead tech, David Shar, built the business on showing up with the right parts and explaining the choices plainly. We are fully mobile. There is no storefront to visit; we bring the work to your property, day or night.

Lock replacement is different from rekeying. Rekeying changes the internal pins so old keys stop working while keeping your existing hardware. Replacement means removing the old lockset and installing a new one, which makes sense when the hardware is damaged, loose, outdated, or when you want a higher security grade, a new look, or smart features. We will tell you honestly which one fits your situation.

How it works in Azusa

  1. 1

    Call and describe the door

    Call (323) 997-8867 and tell us what you have: front door, back slider, garage entry, or a gate. Mention the age of the home and any problems, such as a sticking latch, a loose handle, or a lost key. That helps us bring suitable hardware.

  2. 2

    On-site inspection

    We look at the existing lock, the door, the strike plate and the frame. Many problems blamed on the lock are really alignment or a worn strike, and we will say so if a full replacement is not needed.

  3. 3

    Choose the hardware

    We go over options: standard deadbolts, higher-grade hardware, keyed-alike sets so one key fits several doors, mortise replacements for older doors, or smart locks where the door suits them. You decide what fits your needs and budget.

  4. 4

    Removal and installation

    We remove the old hardware and fit the new lock, adjusting the bore, latch and strike so it throws smoothly. On older doors we take extra care not to damage original wood or cutouts.

  5. 5

    Testing and key handoff

    We cycle the lock repeatedly with the door open and closed, check that every key works, and walk you through any smart features or codes before we leave.

  6. 6

    Aftercare notes

    We share simple maintenance tips and flag anything else we noticed, like a weak frame or a loose hinge screw, so you can decide whether to address it.

What affects the price

  • The type of lock: a basic keyed deadbolt, a higher-security grade, a mortise set, or an electronic smart lock all sit in different price ranges.
  • Number of locks: replacing one front door lock differs from outfitting an entire home or rental with matching, keyed-alike hardware.
  • Door and frame condition: if the bore is damaged, the strike is worn, or the frame needs reinforcing, extra work may be needed.
  • Older or specialty hardware: original mortise locks on historic doors may need specific parts or careful fitting.
  • Time of service: after-hours, weekend and holiday calls can be priced differently from daytime appointments.
  • Location and access: travel distance and whether we need to reach a gated or hard-to-access property can play a role.

Why Azusa chooses us

  • Fully mobile and available 24/7, so a broken lock at night does not have to wait until morning.
  • In business since 1987, with David Shar as owner and lead tech, so experience with older and newer hardware alike.
  • We tell you when a rekey or small repair will solve the problem instead of selling a full replacement.
  • Familiarity with Azusa's mixed housing, from mortise-lock bungalows to new-construction smart-lock-ready doors.
  • Clear explanation of options before work begins, so you know what you are paying for.
  • We test every lock and key before leaving, and we do not leave a door less secure than we found it.

Lock Replacement across Azusa

Azusa's housing is a layered mix, and lock work varies with it. Downtown Azusa along Azusa Ave and Foothill Blvd, the old Route 66 corridor, has 1900s to 1920s bungalows and brick commercial buildings, some still carrying original mortise locks. Those can often be repaired or upgraded, but modern deadbolt retrofits need care so the old wood is not split. If you are in ZIP 91702 near downtown, tell us what the door looks like when you call.

Rosedale, the 2010s master-planned community in the foothills, is a different story. Newer doors there are often well suited to smart locks or multipoint hardware, and we can swap builder-grade sets for something sturdier or more convenient. Mountain Cove, the gated canyon-mouth community, brings its own access considerations, so let us know about gate procedures when you book.

Student rentals around Azusa Pacific University and Citrus College see heavy turnover, especially at semester change. Landlords and tenants often want new or rekeyed locks between leases. Whether you are off Alosta Ave, Gladstone St, near the Metro A Line stations, or up Azusa Ave toward San Gabriel Canyon, we come to you with mobile service from I-210 to the foothills.

Lock Replacement in Azusa — FAQs

What is the difference between lock replacement and rekeying in Azusa?
Rekeying changes the internal pins so old keys no longer work, using your existing hardware. Replacement installs a brand new lock. If your lock is in good shape, rekeying is often enough. Call (323) 997-8867 and we will help you decide.
Can you replace the original mortise lock on my downtown Azusa bungalow?
Often we can repair or upgrade it, and sometimes replace it with a compatible mortise set. We look at the door first so we can protect the original wood. Call (323) 997-8867 to describe what you have.
Do you install smart locks in Rosedale homes?
Yes. Many newer homes are well suited to smart locks, and we can also fit multipoint hardware on suitable doors. We will check door compatibility and show you how the lock works before we leave.
Are you available at night or on weekends?
Yes. We are 24/7 and fully mobile, so you can call at any hour. We do not make timing promises, but we will talk through your situation right away on (323) 997-8867.
I manage student rentals near APU. Can you handle multiple units?
Yes. We can replace or rekey several locks and set them keyed alike if you want. Semester turnover is a common reason to do this, and we can discuss a plan when you call.
How is the price of lock replacement determined?
It depends on the lock type, number of locks, door and frame condition, hardware specifics, and time of service. We explain options before work begins so there are no surprises.
Do you have a shop I can visit?
No. We are mobile only. We come to your home, rental or business anywhere in Azusa, including ZIP 91702.
Should I replace locks after moving into a new home?
It is a smart step, since you cannot know who has copies of old keys. Depending on the hardware, a rekey or full replacement both work. Call us and we will suggest the right option.
