A spare key is one of those small things that feels unimportant until the day it saves you a long, frustrating evening. In Sierra Madre, where many homes are early-1900s Craftsman cottages, Victorians and bungalows, the keys in people's pockets are often decades old, worn smooth, and copied from copies. A duplicate cut from a tired original can pass through several generations of wear until it sticks, spins, or fails in the lock. Getting a clean, accurate copy matters.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business around being fully mobile. We have no shop to drive to. Our technicians bring the cutting equipment to your home, office, or shop, check the new key in your actual lock, and make sure it turns smoothly before we leave. That matters in a town of old hardware, where a key that looks right can still bind in a century-old cylinder.

We handle standard house keys, office and commercial keys, mailbox keys, and restricted or keyed-by-code keys that ordinary hardware counters will not copy. If you are not sure what kind of key you have, call (323) 997-8867 and describe it. We will tell you honestly what can be duplicated on location and what may need extra steps, such as proof of authorization for a restricted system.

How it works in Sierra Madre

  1. 1

    Tell us what you are copying

    Call (323) 997-8867 and describe the key: house, office, mailbox, padlock, or a restricted key with a stamped no-duplicate marking. Tell us where you are in Sierra Madre and how many copies you want. We will explain what is possible on site.

  2. 2

    We come to you

    Because we are fully mobile and available 24/7, the work happens at your door. For homes up in Sierra Madre Canyon, where lanes are narrow and steep, we park where we can and carry the tools needed up to you.

  3. 3

    Inspect the original key and lock

    Before cutting, we look at the key for wear, bends, and damage, and at the lock it operates. A worn original can produce a poor copy, so when needed we may recommend cutting from the lock's actual specification instead of copying the worn key.

  4. 4

    Cut and finish the duplicate

    We cut the new key to match, then deburr and finish the edges so it slides in cleanly and does not shed brass shavings in your lock. Restricted keys are handled according to the rules of their keyway system.

  5. 5

    Test in the real lock

    Every copy is tried in the lock it is meant for, several times, along with the original. If something binds, we recut or adjust before you pay attention to it later at the worst possible moment.

  6. 6

    Label and hand off

    We hand over the originals and the copies, and suggest simple ways to keep spares safe, such as giving one to a trusted neighbor rather than hiding it under a flowerpot.

What affects the price

  • The type of key: a basic house key is a different job from a high-security, restricted, or transponder-style key.
  • How many copies you need, since multiple cuts in one visit are handled more efficiently than separate trips.
  • Whether the original is worn or damaged enough that we should cut from the lock's specification rather than copy it.
  • Authorization requirements for restricted keyways, which can add steps before we are allowed to duplicate.
  • Access to the property, such as hillside lanes in Sierra Madre Canyon where we may need to carry equipment a distance.
  • The time of day or night of the visit, given that we are available 24/7 for urgent needs.

Why Sierra Madre chooses us

  • Fully mobile, so there is no shop trip: the key is cut at your door and tested in your own lock.
  • In business since 1987, with long experience on old hardware, including worn cylinders and non-standard doors common in older foothill homes.
  • Comfortable with original skeleton-key mortise locks, and honest about when a duplicate is practical versus when rekeying or a careful retrofit is the better choice.
  • We copy restricted keys only within the rules of the system, rather than pretending any key can be copied by anyone.
  • Every duplicate is tested in the real lock before we leave, not just compared against the original.
  • A real person answers (323) 997-8867 around the clock, so a late-evening spare-key problem does not have to wait for business hours.

Key Duplication across Sierra Madre

Sierra Madre is a compact, walkable foothill town, and its keys reflect that. Around the village core and Kersting Court, many small shops and cafes need extra keys for new employees or managers, while nearby Craftsman cottages and bungalows near the famous wisteria vine often have older locks and keys that have been copied many times. A fresh, accurate duplicate in the 91024 area can make a stubborn front door work smoothly again.

Sierra Madre Canyon is its own world. Narrow, steep lanes, old cabins, and hillside homes mean parking is limited and the van may have to stay below while we carry tools up. Many of these homes keep original skeleton-key mortise locks or non-standard doors, so we look first at what the hardware actually is before suggesting a copy, a rekey, or a careful retrofit. Properties in the 91025 area range from canyon cabins to homes closer to Sierra Madre Blvd and Michillinda Ave.

Whether you are heading out to Bailey Canyon Wilderness Park or training on the Mount Wilson Trail, or simply getting through a normal week along Baldwin Ave, a spare key is cheap insurance. We serve Sierra Madre at any hour and come to wherever you are, with I-210 nearby for quick access from the surrounding foothill communities.

Key Duplication in Sierra Madre — FAQs

Do you really cut keys at my home in Sierra Madre?
Yes. We are fully mobile with no storefront, so the cutting equipment comes to your door. Call (323) 997-8867 and tell us your address and the type of key.
Can you duplicate the old keys on my Craftsman cottage?
Often, yes. Older keys can be worn, so we inspect them first. If the original is too worn to copy well, we may cut from the lock's specification or suggest rekeying so you get keys that work reliably.
What about skeleton-key mortise locks in Sierra Madre Canyon?
Many canyon cabins have original skeleton-key mortise locks. We can discuss duplicating, rekeying, or carefully retrofitting them while preserving the character of the door. Call (323) 997-8867 to describe your lock.
Can you copy a key marked Do Not Duplicate?
That marking does not always legally or mechanically prevent copying, but restricted keyways are controlled systems. We follow the rules of the system and may need authorization before duplicating. We will tell you plainly what applies.
Do you copy mailbox and office keys?
Yes. We duplicate mailbox, office, and commercial keys, including for small shops around Kersting Court. If you are unsure what your key is, call (323) 997-8867 and we will help identify it.
Is it better to copy a key or rekey the lock?
If you simply want spares and trust everyone who has a key, duplication is enough. If keys were lost or a tenant has moved out, rekeying is the safer choice because old copies stop working.
Are you available at night or on weekends?
Yes, we are available 24/7. Spare-key problems do not keep business hours, and neither do we.
How do you price key duplication?
Price depends on factors like key type, quantity, restricted-key requirements, and access to the property. We do not quote numbers on this page, but we will talk through the specifics with you when you call.
