Most people think of key copying as a quick errand at a hardware counter. In Alhambra, it often isn't that simple. A lot of the city's homes date to the 1910s through 1930s, and many still carry original mortise locks and period doorsets whose keys are not the common blanks hanging on a wall. Add mid-century apartment courtyards with shared entries and mailboxes, plus aluminum storefronts along Main Street and Valley Blvd, and you get a wide range of keys that need careful handling.

Crenshaw Lock Company is fully mobile. There is no shop to drive to; we bring the cutting equipment to you, whether you are in a bungalow in the Bean Tract, an office near the Alhambra campus, or a restaurant getting ready to open. Owner and lead tech David Shar has run the business since 1987, and that long history with older hardware shapes how we approach duplication: look at the lock first, then cut the key.

We are available around the clock. That matters when a spare is needed because you are down to one key, a tenant is moving out, or a key has snapped and you cannot get in. Call (323) 997-8867 and we will help you work out the right way to get a working copy in your hand.

How it works in Alhambra

  1. 1

    Tell us what you need copied

    Call (323) 997-8867 and describe the key: a front door key, a mailbox key, an office key, or something stamped with a restriction notice. Knowing the type up front lets us bring the right blanks and equipment to your Alhambra address.

  2. 2

    We come to you

    Because we are fully mobile, there is no store to visit. We arrive at your home, business or building and work right there, which is especially handy if you only have one key and do not want to hand it off or leave a property unattended.

  3. 3

    Inspect the key and the lock

    Before cutting, we look at the original key for wear and at the lock it operates. A worn key makes a poor master for copying, and older mortise locks sometimes need attention so a fresh copy turns smoothly instead of binding.

  4. 4

    Cut and match the copy

    We cut the new key on location to match the original, using the right blank for the keyway. For restricted keys, we confirm authorization requirements first, since those systems are designed to prevent casual copying.

  5. 5

    Test in the actual lock

    A copy is only good if it works. We try it in the door, mailbox or cabinet it belongs to, several times, and adjust if it sticks. If a key proves too worn to copy well, we will tell you honestly and discuss alternatives such as rekeying.

What affects the price

  • The type of key: a standard house key differs from a high-security, restricted or specialty key, and the blanks and cutting method vary accordingly.
  • How many copies you need, since a single spare and a full set for an apartment building or office are very different jobs.
  • The condition of the original key and lock; a worn original or a stiff vintage mortise lock may need extra work before a copy performs well.
  • Whether the system is restricted and requires authorization or proof of right to copy before we can cut anything.
  • The time of day and location of the call, since we are available 24/7 and travel to you as a mobile service.
  • Whether duplication is paired with other work, such as rekeying a building between tenancies or replacing mailbox and common-area locks.

Why Alhambra chooses us

  • Fully mobile: we cut keys at your door in Alhambra, so you never need to leave a property or surrender your only key.
  • Experience with older hardware: since 1987 we have worked on mortise locks and period doorsets like those in Bean Tract and Midwick Tract bungalows.
  • Available 24/7, including nights and weekends when a lost or broken key will not wait.
  • Honest about limits: if a key is too worn to copy reliably or a restricted system requires authorization, we say so plainly instead of cutting something that will fail.
  • Able to handle residential, mailbox, office and restricted keys in one visit, which helps landlords and small business owners consolidate the job.
  • Every copy is tested in its real lock before we consider the job finished.

Key Duplication across Alhambra

Alhambra has long been called the City of Homes, and the key situations here reflect that. In the Bean Tract and Midwick Tract, two of the city's designated historic neighborhoods, many Craftsman and Spanish or Mediterranean Revival bungalows still have original wood-frame doors and mortise locks. Their keys can be old, worn and unusual, so we copy them with care and check that the lock itself is turning freely. Emery Park and the Airport Tract have their own mix of older houses where a fresh spare is often overdue.

Downtown Alhambra and the Main Street dining and entertainment corridor, near spots like the Garfield Theatre, are full of businesses with aluminum storefronts and mixed-use space above retail. Owners there often need extra employee keys cut or a worn key replaced before opening. Along Valley Blvd, Fremont Ave and Atlantic Blvd, mid-century apartment and courtyard buildings call for multiple copies, mailbox keys and common-area keys, often between tenants.

Whether you are in ZIP 91801 near Main Street or in 91803 closer to the Airport Tract, we come to you, with easy access from I-10 and the main boulevards. Even with the SR-710 stub nearby shaping local traffic, we are mobile and available 24/7. Call (323) 997-8867 and we will head your way with the right equipment.

Key Duplication in Alhambra — FAQs

Do I have to bring my key to a shop?
No. Crenshaw Lock Company is fully mobile with no storefront, so we come to your Alhambra home or business and cut the copy on location. Call (323) 997-8867 to arrange it.
Can you copy keys for older Craftsman or Spanish Revival homes?
Often yes. Many Alhambra homes from the 1910s to 1930s have original mortise locks and older keys. We inspect both the key and lock, and if the key is too worn to copy well, we will explain options like repair or a historically appropriate rekey.
Can you duplicate a key marked Do Not Duplicate?
That marking is not a legal barrier by itself, but restricted key systems are designed to control copying. We confirm authorization where required before cutting. Call (323) 997-8867 to discuss your specific key.
Do you cut mailbox keys?
Yes. We handle mailbox keys for houses and apartment buildings, and can replace the lock if a key is lost. This is common for landlords between tenancies in Alhambra's apartment stock.
I only have one key. Is it safe to copy it?
Usually, but a heavily worn key can produce a copy that works poorly. We inspect it first and test the new key in the lock. If the original is too worn, we will recommend a better route, which may be rekeying.
Can you copy keys for my Main Street business?
Yes. We work with offices, shops and restaurants, including aluminum storefront doors. We can cut extra employee keys, and if a key has broken we can discuss extraction. Call (323) 997-8867.
Are you available outside normal business hours?
Yes, we operate 24/7. If you are down to your last key late at night or on a weekend, call (323) 997-8867 and we will help.
Should I copy keys or rekey after a tenant moves out?
Copying makes more keys that open the same lock, so it does not stop a previous tenant's key from working. Rekeying changes the lock so old keys no longer fit. Many landlords do both: rekey first, then cut new copies.
