Rekeying is the practical answer when you want old keys to stop working but the locks themselves are still in good shape. Inside each cylinder are small pins; we change them so a new key operates the lock and every previous key becomes useless. The hardware stays on your door, the finish stays untouched, and nobody who held a copy of the old key can get in. In Simi Valley it is a common request after buying a house, after a tenant moves out, after a breakup or roommate change, or when a set of keys has gone missing and you would rather not wonder who found them.

Because so much of Simi Valley was built as tract housing between the 1960s and 1990s, many homes still carry original or well-worn Kwikset and Schlage hardware. Rekeying is often the smartest first step on those doors: it resets who has access without the expense of replacing everything. When a deadbolt is badly worn, loose, or sticking, we will tell you honestly whether rekeying is enough or whether swapping in new hardware makes more sense.

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, with no storefront to visit. We bring the tools and key stock to your driveway, work on your schedule, and can match several doors to one key so you carry a single key instead of a ring of them.

How it works in Simi Valley

  1. 1

    Call and describe your doors

    Phone (323) 997-8867 and tell us how many locks you have, what brands they are if you know, and why you are rekeying. Knowing whether it is a move-in, a tenant turnover, or lost keys helps us bring the right parts.

  2. 2

    We come to you

    We are fully mobile and available around the clock, so there is nothing to drop off. A technician meets you at the property, whether that is a ranch home near Tapo Canyon Rd or a gated community in Wood Ranch.

  3. 3

    Inspect each lock

    Before touching a pin, we check each cylinder for wear, loose mounting, and bad latch alignment. A lock that is worn out is better replaced than rekeyed, and we will say so plainly.

  4. 4

    Rekey the cylinders

    We remove each cylinder, replace the pins to match a new key, and reinstall it. Entry knobs, deadbolts, and often side-gate or garage-entry locks can be keyed alike so one key opens them all.

  5. 5

    Test and hand over keys

    We test every new key in every lock, confirm the old key no longer turns, and give you the new keys. Extra copies can be cut on the spot.

What affects the price

  • The number of cylinders being rekeyed, since each lock takes its own bench work.
  • Whether you want all doors keyed alike or each lock on its own key.
  • The brand and condition of the existing hardware, because worn or unusual locks can take more time or may be better replaced.
  • How many extra keys you need cut.
  • Time of day and urgency, since after-hours and same-day calls differ from scheduled daytime appointments.
  • Whether any smart locks or specialty cylinders are included, which can involve extra programming or parts.

Why Simi Valley chooses us

  • Fully mobile service: the work happens at your door, and there is no shop to travel to.
  • Experience since 1987, with an owner-led approach under David Shar rather than an anonymous dispatch.
  • Honest advice on rekey versus replace, so you do not pay for new hardware when a rekey will do.
  • Familiarity with Simi Valley's mix of 1970s tract hardware, HOA-standardized gated-community locks, and older cabin-style homes.
  • Key-alike options so a whole house runs on a single key.
  • Available 24/7, including evenings and weekends, without any timing promises we cannot keep.

Lock Rekeying across Simi Valley

Simi Valley's housing tells you what rekeying usually involves here. In the Texas Tract and across the older tract neighborhoods in ZIP 93065 and 93063, 1970s ranch homes often still have original Kwikset deadbolts that have seen decades of use. After a tenant moves out or a house changes hands, rekeying those doors is a straightforward way to cut off every old key, and if a lock is too worn we can step up to newer SmartKey or Grade-2 hardware.

In Wood Ranch and Big Sky, newer 1990s and 2000s developments often come with HOA-standardized hardware, and more homes are adding smart locks. We work to keep the approved look and finish intact when rekeying or reprogramming, which matters when the neighborhood has rules about exterior appearance. Further into the hills, Santa Susana Knolls has early-twentieth-century cabin-style homes on winding lanes, where older mortise or unusual lock types may need a closer look before we recommend a path. Bridle Path properties can also have gates and outbuildings worth keying alike.

We reach customers across the city, from near the Ronald Reagan Presidential Library and Rancho Simi Community Park to neighborhoods off Madera Rd, Sycamore Dr, and the SR-118 corridor, including ZIP codes 93062, 93064, and 93094. If you are not sure whether rekeying fits your situation, call (323) 997-8867 and we will talk it through.

Lock Rekeying in Simi Valley — FAQs

What does rekeying a lock actually do?
Rekeying changes the internal pins of the lock so a new key works and the old key does not. The lock hardware stays on your door. It is a good choice after moving in, after a tenant leaves, or when keys are lost.
Is rekeying cheaper than replacing locks?
Often it costs less than buying and installing new hardware, but it depends on how many locks you have and their condition. We do not quote numbers on this page. Call (323) 997-8867 and describe your doors for an honest recommendation.
Should I rekey after buying a home in Simi Valley?
Yes, it is a smart habit. You cannot know who has copies of the previous owner's keys, including family, neighbors, contractors, or agents. Rekeying makes sure only the keys you hold will work.
Can you rekey my doors so they all use one key?
In most cases, yes. We can key entry doors, deadbolts, and many side or garage-entry locks alike, provided the locks are compatible brands and in workable condition.
Can you rekey locks in a gated Wood Ranch community?
Yes. We work to preserve the finish and keep to HOA-standard hardware. Smart locks may need reprogramming rather than rekeying, and we can handle that as well. Call (323) 997-8867 to discuss your setup.
When is replacing a lock better than rekeying?
If a lock is loose, badly worn, damaged, or no longer secure, new hardware is the better choice. Older 1970s tract-home deadbolts sometimes fall into this category. We will tell you honestly after inspecting them.
Do you have a shop I can visit?
No. Crenshaw Lock Company is fully mobile. We come to your Simi Valley home or property, so there is nothing to bring in.
Do you rekey after hours or on weekends?
We are available 24/7. Rekeying is often scheduled during the day, but if you need it urgently at night or on a weekend, call (323) 997-8867.
