Irwindale is an unusual place to need a spare key. Most of the land is given over to gravel quarries, aggregate yards, distribution centers, beverage and food plants and sound stages, and the residential population is small, a few hundred homes tucked into the long-established original townsite. That mix means key duplication here covers a wide range, from a worn front-door key on an older single-family house to a stack of copies for a facility manager who needs to hand keys to a new shift.

Crenshaw Lock Company is fully mobile. We have no storefront for you to drive to, which is a real advantage in a city where the nearest hardware counter may be a freeway ride away and where many of our customers cannot easily leave a gate, a plant floor or a job site. We bring the key-cutting equipment to you, copy the key where you stand, and test it in the lock it is meant to open. David Shar has run the business since 1987, and that experience matters most on the awkward jobs: a tired original that will not copy cleanly, or a restricted keyway that needs proper authorization.

We are available around the clock, which suits Irwindale's working rhythm. Plants and quarries run early shifts, late shifts and weekend crews, and a missing copy does not wait for business hours. Whether you need one spare for a house or a controlled set for a facility, a call to (323) 997-8867 starts the conversation.

How it works in Irwindale

  1. 1

    Tell us what you need copied

    Call (323) 997-8867 and describe the key: house, office, mailbox, padlock, gate or something stamped as restricted. Tell us how many copies you want and where in Irwindale you are located.

  2. 2

    We come to your location

    Because we are fully mobile, a technician drives to your home, office, plant or yard with the cutting equipment on board. There is no shop visit and no need to leave your site unattended.

  3. 3

    Inspect the original and the lock

    Before cutting, we look at the original key for wear and check that the lock operates smoothly. A badly worn key copies its own wear, so we flag this early and suggest a fresh cut from the lock if that is the better route.

  4. 4

    Verify authorization for restricted keys

    Restricted and controlled keyways are designed so that copies cannot be made casually. For these we confirm that you are authorized to request duplicates before proceeding, which protects your property and your facility.

  5. 5

    Cut, deburr and test

    We cut the new key, clean off burrs so it does not drag in the cylinder, and try it in the actual lock. If it sticks or turns roughly, we adjust or recut it on the spot.

  6. 6

    Hand over and advise

    You get working keys and practical advice: how to label and track copies, whether an older lock is worth rekeying, and when a high-security system would suit your property better.

What affects the price

  • The type of key: a standard house key is a simpler job than a high-security, dual-sided or restricted key.
  • How many copies you need, since a larger set for a facility or crew takes more time and material than a single spare.
  • The condition of the original, because a heavily worn key may need to be recut or originated from the lock itself.
  • Whether the key is restricted and requires authorization checks or special blanks.
  • The kind of lock involved, such as a mailbox, heavy quarry padlock, gate lock or commercial cylinder.
  • The time of day and the location of the job, as after-hours mobile visits differ from daytime appointments.

Why Irwindale chooses us

  • Fully mobile service: the equipment comes to your door, plant or gate, so nothing needs to be left unattended while you run to a shop.
  • In business since 1987, with owner and lead technician David Shar bringing long experience to difficult or unusual keys.
  • Comfortable with both worlds in Irwindale: older residential locks in the original townsite and commercial cylinders, padlocks and gate hardware at industrial sites.
  • Every copy is tested in the real lock before we leave, instead of being handed over untried.
  • Straight advice about restricted keys and authorization, so you understand why some copies need extra steps.
  • Available 24/7, which fits shift work, early crews and event schedules.

Key Duplication across Irwindale

Irwindale's original townsite, centered roughly around Irwindale Avenue and Los Angeles Street in ZIP code 91706, is where most of the city's homes stand. These are typically older single-family houses with long-tenured owners, and their locks have often been turning for decades. Key duplication here frequently means copying a well-worn original, so we pay close attention to how the copy feels in the cylinder and recommend rekeying when an old lock has outlived its usefulness.

The rest of the city looks very different. The Santa Fe Dam and quarry and industrial district, along with active gravel and sand pits, distribution centers and food and beverage plants like Huy Fong Foods, relies on commercial cylinders, heavy yard padlocks, perimeter gate locks and access-control systems. Managers near the I-605 and Arrow Highway interchange or off Irwindale Avenue often need several matching keys for supervisors and crews, and we can cut them on site. Other Irwindale addresses fall under 91702 and 91010, and we serve those too.

Event venues and public spaces add their own needs. Facilities around the Irwindale Speedway and Event Center, the Santa Fe Dam Recreation Area on Arrow Highway and the Metro A Line station area may need spare keys or gate keys on short notice. With I-210, I-605 and Live Oak Avenue giving easy access in every direction, we can reach most of the city around the clock. Call (323) 997-8867.

Key Duplication in Irwindale — FAQs

Do I need to bring my key to a shop in Irwindale?
No. Crenshaw Lock Company is fully mobile and has no storefront. We come to your home, office, plant or yard and cut the copy there. Call (323) 997-8867 to arrange it.
Can you duplicate keys at night or on weekends?
Yes. We are available 24/7, which helps businesses in Irwindale that run early, late or weekend shifts. Call (323) 997-8867 any time and we will talk through what you need.
Can you copy a key marked Do Not Duplicate?
That marking alone does not always prevent copying, but truly restricted keyways are controlled. We confirm you are authorized before duplicating them, and we will explain what is possible for your specific key.
Can you make multiple copies for a quarry, plant or warehouse?
Yes. We can cut sets of matching keys for supervisors and crews on site, including keys for commercial cylinders and heavy padlocks. We can also discuss whether a keyed-alike setup or access control would be easier to manage.
What if my original key is badly worn?
A worn original can produce a copy that sticks or fails to turn. We inspect it first, and if needed we recut the key or make a new one from the lock. This is common with older homes in the original townsite.
Can you duplicate mailbox keys?
Yes, we copy mailbox keys on location along with house and office keys. If you have lost the only key, tell us when you call (323) 997-8867 so we can plan the right approach.
How is the cost of key duplication determined?
Cost depends on the type of key, the number of copies, the condition of the original, whether it is restricted, and the time and place of the visit. We do not guess over the phone, so call (323) 997-8867 and describe the job.
Do you serve all Irwindale ZIP codes?
Yes, we serve Irwindale addresses in 91706, 91702 and 91010, from residential streets near the townsite to industrial and quarry properties across the city.
