Rekeying changes the inside of a lock so that a new key works and every old key does not. The lock hardware stays on the door. For a lot of Sierra Madre homeowners, that is exactly the right fix: you keep the handsets and deadbolts you like, and you shut out whoever might still be carrying a copy, whether that is a previous owner, a former tenant, a contractor or an ex-roommate.

It is also one of the most practical steps after buying a house here. Many homes in town are early-1900s Craftsman cottages, Victorians and bungalows, and nobody can say how many keys have been handed out over the decades. Rekeying every exterior door to one fresh key gives you a clean starting point, usually for far less than replacing all the hardware.

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, so we come to your door with the tools and key blanks needed, whether you live in the village core, up in Sierra Madre Canyon, or run a shop near Kersting Court.

How it works in Sierra Madre

  1. 1

    Call and describe your doors

    Call (323) 997-8867 and tell us how many exterior doors you have, what kind of locks are on them, and why you want to rekey. Mention anything unusual, such as an old mortise lock, a gate lock or a door that sticks, so we bring the right tools.

  2. 2

    We come to you

    We are a mobile service with no shop to visit. A technician drives to your home or business, and if you are on a narrow canyon lane, we plan on carrying equipment from wherever the vehicle can reasonably park.

  3. 3

    Inspect each lock

    Before taking anything apart, we check that each lock is in good working order. A cylinder that is worn, damaged or poorly made may not be worth rekeying, and we will tell you plainly if replacing it makes more sense.

  4. 4

    Rekey the cylinders

    We remove the cylinders, replace the internal pins to match a new key, and reassemble them. Locks can be keyed alike so one key opens the front, back and side doors, or kept separate if you prefer.

  5. 5

    Test every lock and key

    We operate each lock with the new key several times, confirm the bolts throw smoothly, and make sure the old key no longer turns the cylinder. Then we hand over your new keys.

What affects the price

  • The number of locks or cylinders being rekeyed, since each one is worked on individually.
  • The type of lock: standard deadbolts and knobsets differ from older mortise cases or specialty hardware.
  • Whether you want all locks keyed alike or want separate keys for different doors.
  • How many extra keys you need cut once the rekey is done.
  • The condition of the existing hardware, because worn or damaged cylinders may need replacement instead.
  • Time of day and access conditions, such as after-hours calls or a hard-to-reach hillside property.

Why Sierra Madre chooses us

  • Fully mobile, 24/7: we work at your door at any hour, and there is no storefront to drive to.
  • Operating since 1987, so older and non-standard hardware is nothing new to us.
  • Honest recommendations: if a lock should be replaced instead of rekeyed, we say so rather than upsell.
  • Experience with vintage hardware, including original mortise locks found in century-old homes.
  • Owner-led: David Shar leads the work, so the person who knows the trade is the one standing at your door.
  • Keyed-alike options so you carry one key instead of a ring of them.

Lock Rekeying across Sierra Madre

Sierra Madre is a compact, walkable foothill town, and its housing tells you a lot about what rekeying looks like here. Around the village core in ZIP code 91024, you find Craftsman cottages, Victorians and bungalows, many of them near the wisteria vine that draws visitors each spring. When a home near there changes hands or a tenant moves out, rekeying all the exterior doors is a sensible way to know exactly who holds a key.

Sierra Madre Canyon is its own world. Narrow, steep lanes lead to old cabins and hillside homes, and many still have original skeleton-key mortise locks and non-standard doors. Because our service is mobile, we plan for the access: if the lane is too tight, we park below and carry tools up. For a lock like that, we look carefully at whether it can be rekeyed or carefully retrofitted so the character of the door is kept. Properties in the 91025 area and nearby streets off Sierra Madre Blvd, Baldwin Ave and Michillinda Ave get the same attention.

Businesses matter too. Small shops and cafes ring Kersting Court in the downtown, and a departing employee or a changed lease is a good reason to rekey the storefront cylinders. Whether you are near Mary's Market, heading back from Bailey Canyon Wilderness Park, or just off the I-210 Foothill Fwy, call (323) 997-8867 any time of day or night.

Lock Rekeying in Sierra Madre — FAQs

What does rekeying a lock actually do?
It changes the internal pins of the cylinder so a new key works and the old keys no longer do. The lock itself stays on the door. Call (323) 997-8867 if you want to talk through your situation.
Should I rekey after buying a home in Sierra Madre?
It is a good idea. You cannot know who has copies of the old keys, especially in a house that is a century old. Rekeying every exterior door gives you a fresh start without replacing all your hardware.
Can you rekey an original skeleton-key mortise lock?
Often we can rekey or carefully retrofit them, but it depends on the lock's condition and design. Many Sierra Madre Canyon cabins have these. We inspect first and tell you honestly which option makes sense.
What if my canyon lane is too narrow for your vehicle?
That is common in Sierra Madre Canyon. We park below and carry the tools up to your door. Mention the access when you call (323) 997-8867 so we plan accordingly.
Is rekeying better than replacing the locks?
If your locks are in good condition and you like them, rekeying is usually the more economical option. If they are worn, damaged or low quality, replacing may be wiser, and we will tell you which applies.
Can all my doors use the same key?
Yes. We can key the front, back and side doors alike so one key opens them all, as long as the locks are compatible with that approach.
Do you rekey commercial locks near Kersting Court?
Yes. We handle cylinder rekeys and lockouts for small shops and cafes, which is useful after staff changes or a lease turnover.
Can I get rekeying at night or on a weekend?
Yes. We are available 24/7 and fully mobile. Call (323) 997-8867 at any hour to reach us.
