Locks wear out quietly. A deadbolt that needs a shoulder push, a knob that spins freely, a key that sticks halfway in: these are signs that the hardware is near the end of its life, or that it was never a good fit for the door. In Arcadia, where many homes date from the 1950s and 1960s, original hardware is still common, and so are mismatched locks left over from years of piecemeal repairs.

Lock replacement means removing the old hardware and installing new locks that suit the door, the frame and the way you live. Sometimes that is a single deadbolt. Sometimes it is every exterior door on a house, a condo unit after a tenant leaves, or the cylinders in a shop space. It is also different from rekeying, which changes the inside of an existing lock so old keys stop working. If your hardware is still in good shape, rekeying may be all you need, and we will say so honestly.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no storefront to drive to. Owner and lead technician David Shar and our team bring the tools and a range of hardware to your door, so the job can be done where the problem is, including at night or on a weekend.

How it works in Arcadia

  1. 1

    Tell us what is going on

    Call (323) 997-8867 and describe the doors involved, what the locks are doing, and why you want a change. A lost key, a break-in, a move, a remodel and plain wear each point toward different hardware, so a few questions up front help us bring the right parts.

  2. 2

    Inspect the doors and existing hardware

    On site, we look at the lock, the strike plate, the door edge and the frame. Worn or misaligned parts are often the real cause of a sticking lock, and a new lock on a bad door will not last. We tell you what we see before any work starts.

  3. 3

    Choose hardware that fits

    We go over options for each door: deadbolts, knobs, levers, smart-ready locks, and higher-security cylinders. We talk about how many people need keys, whether you want keyed-alike doors, and whether a master-key arrangement makes sense for a larger property.

  4. 4

    Remove the old lock and install the new one

    We take out the old hardware and fit the new lock, adjusting the latch, strike and bolt throw so it closes smoothly and fully. If the door needs minor preparation to accept the new hardware, we handle that during the visit.

  5. 5

    Key, test and hand over

    We cut or set the keys, then test every lock repeatedly from both sides with the door open and closed. You receive working keys and a clear understanding of how each lock operates. Old keys to replaced locks no longer matter.

What affects the price

  • How many locks are being replaced, and whether they are deadbolts, handlesets, knobs or cylinders.
  • The grade and type of hardware you choose, from standard residential locks to high-security or electronic models.
  • Whether doors need adjustment, such as a misaligned strike, a damaged edge or a bore that needs to be enlarged.
  • Keying requirements, including keyed-alike sets or a master-key system across many doors.
  • Time of service, since nights, weekends and holidays are handled differently from a scheduled daytime visit.
  • Whether the job is residential, a multi-unit property, or commercial work involving specialty cylinders.

Why Arcadia chooses us

  • Fully mobile service. We work at your door rather than asking you to bring hardware to a shop, because we have no storefront.
  • Available around the clock, so a broken lock or a security concern does not have to wait for business hours.
  • In business since 1987, which means long experience with the older ranch-style hardware still found throughout the San Gabriel Valley foothills.
  • We tell you when rekeying or a simple repair will do the job, rather than pushing a full replacement.
  • Experience with keyed-alike and master-key setups for new custom homes, multi-unit buildings and commercial tenant spaces.
  • Every lock is tested before we leave, and you are walked through how it works.

Lock Replacement across Arcadia

Arcadia has a mix of housing that makes lock replacement a regular need. In Upper Rancho, Lower Rancho and Highland Oaks, older ranch homes are steadily being torn down and rebuilt as large custom estates. A new build often calls for a full lockset package across many doors, usually keyed alike or tied into a master-key system so the owner, family and household staff each carry only what they need. Owners of older homes nearby, in areas like Baldwin Stocker, often have decades-old original hardware that is overdue for replacement.

Closer to Santa Anita and along Huntington Drive, condos and apartments create a different pattern. A tenant who gets locked out late at night may need help in the moment, and a new move-in is a good time to replace or rekey locks, since previous residents may still hold keys. Properties in ZIP code 91006 and 91007 are among the areas we serve, along with 91066 and 91077, and we travel to homes in Peacock Village as well.

Commercial tenants around Westfield Santa Anita and the strip centers off Baldwin Avenue and Santa Anita Avenue also need cylinder service when a tenant changes or keys are lost. Whether you are near the Arboretum, close to Methodist Hospital, or just off the I-210 or Rosemead Boulevard, call (323) 997-8867 and we will come to you.

Lock Replacement in Arcadia — FAQs

What is the difference between lock replacement and rekeying?
Rekeying changes the internal pins of your existing lock so a new key works and old keys do not. Replacement installs entirely new hardware. If your locks are in good condition, rekeying is often enough. If they are worn, damaged, or you want a different style or security level, replacement makes more sense. Call (323) 997-8867 and we can help you decide.
Do you offer lock replacement in Arcadia at night?
Yes. We are available 24 hours a day, 7 days a week, and we are fully mobile, so we come to your home, condo or business. Call (323) 997-8867 any time, including after a break-in or lockout.
Can you replace the locks on a newly built home?
Yes. Arcadia has a lot of teardown-and-rebuild construction, and we can supply and key a full lockset package, including keyed-alike doors or a master-key system. Tell us how many doors and who needs access, and we will plan the keying around that.
I just moved into an Arcadia condo. Should I change the locks?
It is a smart idea. You cannot know how many keys previous residents or others kept. We can replace or rekey the locks at move-in so only the keys you hold will work.
Do I need to be home during the replacement?
Someone authorized should be present, at least at the start and end, so we can confirm which locks to change and hand over keys. We will go over the work with you before and after.
Can you replace locks at a shop near Westfield Santa Anita?
Yes. We handle commercial cylinder service and rekeying for tenant spaces in shopping centers. Details about the lease and any building requirements are worth sharing when you call (323) 997-8867.
Will new locks fit my older door?
Usually yes. Most doors from the 1950s and 1960s accept modern deadbolts and locksets, though some need minor adjustments to the bore, edge or strike plate. We inspect the door first and tell you if anything extra is needed.
Do you have a shop I can visit?
No. We are a fully mobile locksmith with no storefront. We bring hardware and tools to your location anywhere in Arcadia, including ZIP codes 91006, 91007, 91066 and 91077.
