Rekeying is the simplest way to take back control of who can open your doors. Instead of replacing a lockset, a technician alters the inside of the cylinder so it works with a new key and the old keys become useless. It is a sensible step after buying a house, ending a lease, losing a key, or parting ways with a roommate, contractor, or former employee. In Claremont, where many owners care about keeping original hardware, it is often the best option.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on practical, honest locksmithing. We are fully mobile. There is no storefront to visit; we come to your door in Claremont with the tools and key blanks needed to do the work on site, day or night.

This page explains how rekeying works, what affects the cost, and what is specific to Claremont: Craftsman bungalows near the Village with older hardware, hillside homes in North Claremont and Claraboya, and the commercial and institutional properties around Yale Ave and the Claremont Colleges.

How it works in Claremont

  1. 1

    Tell us about your locks

    Call (323) 997-8867 and describe what needs rekeying: how many doors, whether they are deadbolts, knob sets, or older mortise locks, and why you want the change. Details like the brand and age of the hardware help us bring the right parts.

  2. 2

    We come to you

    Because we are mobile and available 24/7, we travel to your Claremont address with pinning kits, key-cutting equipment, and common replacement parts. Nothing needs to be dropped off, and your doors stay in place.

  3. 3

    Check the hardware

    Before changing anything, we look at each lock to confirm it is in good working order. A cylinder that is worn, damaged, or poorly fitted may not hold a rekey well, and we will tell you plainly if a repair or replacement would serve you better.

  4. 4

    Rekey the cylinders

    We remove each cylinder, replace the pins to match a new key cut, and reassemble it. Where you want convenience, we can pin several locks to one key so a single key opens the front door, back door, and garage entry.

  5. 5

    Test and hand over keys

    We test every lock with the new key and confirm the old key no longer turns. You receive the new keys, and we can cut extras on site. We also suggest keeping a spare somewhere safe, away from the property.

What affects the price

  • The number of cylinders being rekeyed, since each lock takes its own time to remove, repin, and test.
  • The type of lock: standard deadbolts and knob sets differ from mortise cylinders, high-security cylinders, or restricted keyways.
  • Whether you want all locks keyed alike, or a master-key arrangement with separate levels of access.
  • How many new keys you need cut, and whether any of the keys are specialty or restricted blanks.
  • The condition of the existing hardware, because worn or damaged locks may need repair or replacement parts before rekeying works reliably.
  • The time of day and location of the visit, as after-hours and out-of-the-way calls can affect the overall service charge.

Lock Rekeying across Claremont

Claremont's character shapes how rekeying is done here. In and around Claremont Village, many homes date from the early 1900s through the 1920s, and Craftsman bungalows often still carry original mortise locks. Owners usually want to keep that hardware, and a careful rekey lets a house change hands or a key go missing without losing period detail. Homes in ZIP code 91711 along tree-lined streets near Yale Ave, Indian Hill Blvd, and Base Line Rd are frequent candidates.

North Claremont and the hillside Claraboya area include newer homes with modern deadbolts and multiple entries, where keying everything to one key is a popular request, especially after a purchase. Residents near Claremont Hills Wilderness Park and the foothills often have side gates, garage doors, and patio entries that are worth including in the same visit.

Near The Claremont Colleges and Village shops, the needs shift. Landlords of off-campus rentals often rekey between tenants, and small retailers on Yale Ave may want locks changed after staff turnover. Large campus buildings run institutional master-key systems that we do not assume we can alter; for any property, tell us what you have and we will say what we can do. From I-10 and SR-210 to Foothill Blvd and Towne Ave, we reach Claremont day or night.

Lock Rekeying in Claremont — FAQs

What is the difference between rekeying and replacing a lock?
Rekeying changes the inside of the existing cylinder so a new key works and old keys do not. Replacing swaps the whole lock. Rekeying keeps your current hardware and is often the better choice when the lock is in good shape.
Should I rekey after buying a home in Claremont?
Yes, it is a wise step. You cannot know how many copies of the old keys exist. Call (323) 997-8867 and we can rekey the exterior doors so only keys you hold will work.
Can you rekey the original mortise locks in a Craftsman bungalow?
Often, yes, if the cylinder and lock body are sound. We assess each one first. If a mortise lock is too worn, we will explain the options, including repair, so you can preserve as much of the original hardware as possible.
Can all my locks work with one key?
Yes. We can key multiple locks alike so one key opens the front, back, and garage doors, provided the locks are compatible. Tell us which doors you want included when you call.
Do I need to be home during the rekey?
Someone with authority over the property should be present or arrange access. Rekeying is done at the door, so we need to reach each lock. Call (323) 997-8867 to plan around your schedule.
Will my old keys still work afterward?
No. Once a cylinder is rekeyed, the old key will not turn it. We test this at the end of the visit so you can see it for yourself.
Can you help with locks at a business near Yale Ave?
Yes. We handle rekeying for small commercial doors such as shops and offices, including after staff changes. Larger institutional systems vary, so describe your setup and we will tell you what is possible.
Are you available outside normal business hours?
Yes, we are available 24/7 and fully mobile, so we can come to your Claremont location when needed. We make no promises about timing over the phone beyond that, but we will give you a clear plan when you reach us.
