Duarte is a foothill city with a lot of character in its housing. Much of the Butler and Cotter areas is made up of single-story ranch and tract homes from the 1950s and 1960s, and those houses have often gone through several owners, several sets of keys and more than a few worn-out locks. Add the newer condos and apartments near the A Line, plus custom homes climbing toward Royal Oaks and Fish Canyon, and you get a community where home lock needs vary a lot from one street to the next.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile and open 24/7, which matters for residential work because lockouts, break-ins and lost keys rarely happen at convenient times. Whether you need one stubborn deadbolt fixed or every exterior door on the house brought onto a single key, the work happens at your property.

This page explains how residential locksmith work usually goes in Duarte, what affects the cost, and what to expect when you call. We do not quote prices without knowing the job, so you will find the factors that matter instead of made-up numbers. If you want to talk it through, call (323) 997-8867.

How it works in Duarte

  1. 1

    Call and describe the situation

    Phone (323) 997-8867 and tell us what is going on: locked out, just bought the house, a door that will not latch, or a break-in attempt. Tell us the type of home and which doors are involved so we can bring the right hardware and tools.

  2. 2

    We come to you

    Because we are fully mobile, a technician travels to your home, whether it is a tract house in Butler, a condo near the A Line or a hillside property up toward Fish Canyon. There is no shop to visit. We confirm the work and the cost factors before starting.

  3. 3

    Assess the locks and doors

    We look at the existing hardware on front, back, side and garage doors, along with the door, frame and strike plate. On older ranch homes, loose strike plates, worn cylinders and mismatched brands are common, and spotting them early keeps the fix simple.

  4. 4

    Rekey, repair, replace or upgrade

    Depending on condition, we rekey cylinders so old keys no longer work, repair sticking or loose hardware, or replace the lock entirely. Upgrades like a stronger deadbolt, longer strike screws or a better gate lock are discussed with you, never forced on you.

  5. 5

    Test and hand over keys

    We operate every lock repeatedly, confirm each door closes and latches cleanly, and make sure the keys you are given work across all the doors that were rekeyed. You leave knowing exactly who can and cannot get in.

What affects the price

  • Whether the job is a rekey, a repair or a full replacement, since each involves different parts and labor.
  • The number of locks involved, such as a single deadbolt versus front, back, side and garage doors for a whole-house rekey.
  • The grade and brand of hardware you choose, from standard residential deadbolts to higher-security options.
  • Door and frame condition, because a damaged jamb or loose strike plate may need reinforcement for the new lock to do its job.
  • The type of lockout, including whether the door can be opened without damage or the lock must be drilled or replaced.
  • Time of day and urgency, since after-hours emergency calls differ from scheduled work.

Why Duarte chooses us

  • Family-style experience since 1987, with David Shar as owner and lead technician rather than a faceless dispatch center.
  • Fully mobile and 24/7, so lockouts and post-break-in repairs are handled when they happen, not when a shop opens.
  • Familiarity with the tract-home hardware common in 1950s and 1960s ranch houses, including worn cylinders and original locksets.
  • Honest recommendations: if a rekey will do the job, we will not push a full replacement.
  • Clear explanation of cost factors before work begins, with no invented or inflated quotes.
  • Experience across home types, from condos to custom foothill houses with gates and outbuildings.

Residential Locksmith across Duarte

Duarte's housing tells a clear story about its lock needs. In the Butler and Cotter neighborhoods, rows of single-story ranch and tract homes in ZIP code 91010 often change hands, and a common request is a whole-house rekey right after closing so the front door, back door and garage door all work on one key and previous owners' copies stop working. Many of these homes still have original or mismatched hardware, which makes the visit a good time to look at deadbolt quality too.

Up toward Royal Oaks and the Fish Canyon area, properties are more varied: custom homes, longer driveways, side gates and detached structures. After a break-in attempt, we often see homeowners wanting a stronger deadbolt, reinforced strike plates and a better gate lock. Homes near the Fish Canyon Falls trailhead and along Mountain Avenue can feel tucked away, which is one more reason people prefer solid hardware on every entry point. ZIP code 91009 also covers parts of the city where condos and apartments sit closer to Huntington Drive and the A Line, where rekeys and lockout help are frequent.

Duarte is also home to City of Hope, and many medical professionals who work there live nearby. Long shifts and odd hours mean lockouts happen at night or early morning, and a 24/7 mobile locksmith fits that reality. Whether you are near Encanto Park, off Buena Vista Street, or just off the I-210 or I-605, we come to you. Call (323) 997-8867.

Residential Locksmith in Duarte — FAQs

Do you offer residential locksmith service in Duarte at night?
Yes. We are available 24/7 and fully mobile, so night, weekend and holiday calls are part of the normal service. Call (323) 997-8867 and describe the situation.
Should I rekey or replace the locks after buying a home in Duarte?
Often a rekey is enough. It changes the internal pins so old keys stop working while keeping the existing hardware. If the locks are worn, damaged or low quality, which can happen in older ranch homes, replacement may be the better choice. We will look at them and tell you honestly.
Can you put the front, back and garage doors on one key?
Yes. Consolidating exterior doors onto one key is a common request after a purchase in the Butler and Cotter areas. Depending on the hardware, we rekey or swap cylinders so one key works throughout.
Do you have a shop I can visit?
No. We are a mobile-only business with no storefront. A technician comes to your home in Duarte with the tools and hardware needed for the job.
I had a break-in attempt. What should I do?
Make sure everyone is safe and report it if appropriate, then call us at (323) 997-8867. We can inspect doors, frames and strike plates, upgrade deadbolts and address gate locks, which is especially common on foothill homes toward Royal Oaks and Fish Canyon.
How much does a residential locksmith visit cost?
It depends on the work: rekey versus replacement, number of locks, hardware grade, door condition and time of day. We do not quote a number without knowing the job, but we explain the factors up front so there are no surprises.
Can you help if I work at City of Hope and am locked out?
Yes. We handle residential lockouts at any hour and can also discuss a deadbolt upgrade afterward. Call (323) 997-8867 and tell us where you are in Duarte.
Will opening my door damage the lock?
We try non-destructive entry first and often succeed. If a lock is damaged, very worn or high security, drilling or replacement may be needed, and we explain that before proceeding.
