Most people think of key copying as a counter transaction at a hardware store, but in El Monte it often makes more sense to have the work come to you. Many homes here are post-war single-story tract houses with original-era Kwikset and Schlage knobs and deadbolts. Keys that have been copied from copies for decades tend to wear, and a worn copy can stick, bind or break off in the lock. Our mobile service lets us cut a fresh, accurate key on location and test it in the lock it is meant to operate.

Crenshaw Lock Company is fully mobile. There is no storefront to visit; our technician drives to your home, apartment, shop or office with key-cutting equipment and a range of blanks. That is particularly handy if you manage several units, run a business along Valley Blvd or Garvey Ave, or simply cannot leave a household member or property unattended. Because we are available around the clock, duplication does not have to wait for a weekday.

Owner and lead technician David Shar has worked in this trade since 1987, and the approach is simple: look at the key and the lock, tell you plainly what can be copied, and test the result before we leave. Some keys are straightforward. Others, such as restricted or patent-protected keys, carry rules about who may authorize copies. We explain those up front so there are no surprises.

How it works in El Monte

  1. 1

    You call and describe the key

    Call (323) 997-8867 and tell us what you need copied: a house key, an office key, a mailbox key or something stamped with a restriction. Any brand name or markings on the head of the key help us bring the right blanks.

  2. 2

    We come to your location

    Our technician travels to you anywhere in El Monte, whether that is a single-family home near Norwood, an apartment complex off Garvey Ave or a storefront on Valley Blvd. There is no shop to visit, since the service is entirely mobile.

  3. 3

    Inspect the original and the lock

    We look at the original key for wear and check how it operates in the lock. If a key is badly worn, we may suggest cutting the copy from the lock's actual specifications rather than copying the worn shape.

  4. 4

    Verify authorization for restricted keys

    Restricted keys are controlled for a reason. Before copying one, we confirm that you are the person entitled to authorize duplicates, such as the property owner or an authorized manager. If a key cannot be legitimately copied, we say so and discuss alternatives.

  5. 5

    Cut and test

    We cut the key on location and try it in your lock several times, checking that it enters smoothly, turns freely and retracts the bolt fully. Any rough edges are cleaned up before you receive it.

  6. 6

    Hand-off and advice

    We give you the original and the copies, and can suggest practical steps such as keeping a spare with someone you trust or rekeying if keys have gone missing.

What affects the price

  • The type of key: a standard house key is a simpler job than a high-security, restricted or specialty key that needs particular blanks.
  • How many copies you need, and whether they are all for the same lock or for several locks across a property.
  • The condition of the original key, since a badly worn original may call for extra work to get a copy that operates smoothly.
  • Your location and the time of day, because we are mobile and available 24/7, including nights, weekends and holidays.
  • Whether the job involves restricted keys, which may require authorization checks and special blanks.
  • Whether the lock itself needs attention, such as a sticking cylinder that is damaging keys, which would be quoted separately.

Why El Monte chooses us

  • Fully mobile: we cut keys at your door, so you do not need to leave a home, tenants or a business unattended.
  • Serving Greater Los Angeles and Ventura County since 1987, with an owner-led approach under David Shar.
  • Familiarity with the hardware common in El Monte's tract homes, courtyard apartments, mobile-home parks and aluminum-storefront shops.
  • Every key is tested in your actual lock before we leave, instead of being handed over untried.
  • Honest about restricted keys: we explain authorization rules clearly and will not copy a controlled key without proper authority.
  • Available 24/7, so duplication can happen outside normal retail hours.

Key Duplication across El Monte

El Monte is a dense mix of residential and commercial blocks, and key needs vary a great deal from one part of town to another. Around Norwood, where some 1920s and 1930s bungalows still stand beside later tract homes, we often see original hardware that has been rekeyed or re-copied many times, and keys that no longer match the lock cleanly. In Mountain View, the typical single-story stucco home with a Kwikset or Schlage knob and deadbolt is a quick, familiar job for on-site duplication.

Near Downtown El Monte and Valley Mall, and along Valley Blvd and Garvey Ave, businesses use aluminum-storefront doors and roll-up security gates, where keys for gate locks and storefront cylinders may need copying for new employees or managers. Courtyard and garden apartment buildings off Garvey Ave are another common scenario: after a move-out, a property manager may need extra keys cut for a unit. We also work with residents in the city's mobile-home parks, which use their own narrow-stile and park-model latch systems that standard keys and blanks do not always suit.

We serve ZIP codes 91731, 91732, 91733, 91734 and 91735, including addresses near the El Monte Bus Station, the Metrolink station on Railroad St, Gibson Mariposa Park and the Rio Hondo and San Gabriel River corridor. Whether you are close to Interstate 10, Interstate 605, Peck Rd or Santa Anita Ave, call (323) 997-8867 and we will come to you.

Key Duplication in El Monte — FAQs

Do you really come to my home in El Monte to copy keys?
Yes. We are fully mobile and have no storefront. Our technician brings the equipment to your home, apartment or business, cuts the key there and tests it. Call (323) 997-8867 to set it up.
Can you copy a key marked "Do Not Duplicate"?
That marking is not always a legal barrier, but we take it seriously. We look at the key, confirm you have the authority to request copies, and explain what is possible. If a key is truly restricted, we discuss the proper route for getting authorized duplicates.
Can you duplicate keys at night or on weekends?
Yes, we are available 24/7. If you need a spare key outside normal hours, call (323) 997-8867 and we will talk through the job and schedule it.
Can you copy mailbox keys?
Generally yes, when you are the person entitled to access the mailbox. Cluster or apartment mailboxes may be controlled by the postal service or property management, so we may ask about authorization first.
My key is worn and the copy might not work. What can be done?
A copy of a worn key inherits the wear. We check the original and the lock, and where appropriate we can cut a key based on the lock's proper specifications rather than copying the worn shape, so it operates smoothly.
Do you handle keys for mobile-home parks in El Monte?
Yes. Park-model units often use narrow-stile latches and their own deadbolt styles. Tell us what you have when you call (323) 997-8867 so we bring suitable blanks.
Can you make extra keys for a tenant turnover at my apartment building?
Yes. Property managers often have us cut additional keys or, if previous tenants may still hold keys, suggest rekeying the locks. We can work through multiple units in one visit.
Can you copy keys for a roll-up gate or storefront lock?
We can copy many storefront and gate-lock keys on site. If a cylinder is jammed or damaged, we inspect it first, since forcing a copy into a failing lock can make the problem worse.
