Most people think of key duplication as a quick errand at a hardware counter. In Rowland Heights that errand often means a drive down Colima Rd or Fullerton Rd, a search for parking, and a kiosk that cannot handle the key you actually have. Our work is different: we are fully mobile, so the key machine comes to you, whether you are in a two-story tract home on a Powder Canyon hillside or in a suite above a restaurant in the Colima and Nogales commercial core.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business around doing this kind of work properly. A good copy is not just a matching shape. It is a key cut cleanly from a sound original, checked in the lock it is meant to operate, and tested so that it turns smoothly rather than binding or wearing the cylinder.

Rowland Heights has an unusual mix of keys. The hillside neighborhoods are mostly 1970s and 1980s tract homes with standard residential cylinders, and a growing number of smart locks that still rely on a mechanical backup key. The retail plazas bring aluminum-storefront deadbolts, roll-gate padlocks, mailbox keys and the occasional restricted key system. We handle all of these on location, at any hour.

How it works in Rowland Heights

  1. 1

    You call and describe the keys

    Call (323) 997-8867 and tell us what you need copied: house keys, a suite key, a mailbox key, a padlock key or something stamped with a do-not-duplicate marking. Knowing the lock brand and how many copies you want helps us bring the right blanks.

  2. 2

    We come to your location

    Because we are mobile, there is nothing to drop off. We drive to your home, office or plaza suite with key-cutting equipment and a range of blanks, any hour of the day or night.

  3. 3

    We inspect the original key and lock

    Before cutting, we look at the original. A worn, bent or heavily copied key can pass its flaws to every duplicate, so if the original is tired we may suggest cutting from the lock's code or making a fresh key instead.

  4. 4

    We cut and finish the copies

    We match the correct blank to your keyway and cut the new keys, then remove burrs so they enter and turn smoothly. Restricted or high-security keys may need authorization, and we will explain what that involves.

  5. 5

    We test every key in the actual lock

    Each copy is tried in the lock it belongs to, multiple times, including a smart lock's mechanical override if it has one. If something sticks, we adjust or recut it before we leave.

What affects the price

  • The type of key: a standard residential key is a simpler job than a high-security, restricted or tubular key that requires special blanks or equipment.
  • How many copies you need, and whether you are duplicating one key or setting up a full set for a household or several tenants.
  • The condition of the original key, since a worn original may call for a code-based cut or a replacement rather than a simple copy.
  • Whether the key is restricted and requires proof of authorization before it can be copied.
  • The time of day, since after-hours and overnight visits differ from scheduled daytime appointments.
  • Whether several locations are handled in one visit, such as multiple suites in a single plaza.

Why Rowland Heights chooses us

  • We are fully mobile, so there is no storefront. The cutting happens at your door, which matters when you cannot leave a restaurant or a building unattended.
  • We have served the Los Angeles area since 1987, and that experience shows in how we judge a worn original or an unfamiliar keyway.
  • We test every copy in the real lock before leaving, rather than handing you a key and hoping it works.
  • We are comfortable with both residential hardware and commercial plaza hardware, from tract-home cylinders to aluminum-storefront deadbolts and roll-gate padlocks.
  • We are honest about restricted keys. If a key requires authorization, we will say so plainly instead of bypassing the system.
  • We are available 24/7, so a lost spare or a new tenant's key need does not have to wait for business hours.

Key Duplication across Rowland Heights

Rowland Heights stretches from the busy Colima Rd and Nogales St corridor up into the hillside tracts near Powder Canyon, and the keys on each end of that stretch are very different. Around Diamond Plaza, Hong Kong Plaza and Pearl Plaza, in the area many people call Little Taipei, restaurants, markets and offices above retail depend on aluminum-storefront deadbolts, roll-gate padlocks and exit hardware. A property manager there might need several suite keys copied or rekeyed between tenants, and we can do that in one mobile visit instead of sending anyone to a shop.

Up in the Powder Canyon hillside tracts and around the Fairway Dr area, the homes are mostly two-story 1970s and 1980s builds on view lots. Standard residential cylinders are common, and more owners are adding smart deadbolts. Those smart locks usually have a mechanical backup key, and a dead battery can leave a homeowner outside, so having a good spare cut ahead of time is worth the effort. We can copy that backup key and test it against the lock.

We serve ZIP code 91748 and the surrounding area, reaching you from SR-60, Fullerton Rd or wherever you happen to be, whether that is near Schabarum Regional Park, the Powder Canyon trails or a plaza parking lot. Call (323) 997-8867 any hour.

Key Duplication in Rowland Heights — FAQs

Can you copy keys at my home in Rowland Heights?
Yes. We are fully mobile and bring key-cutting equipment to your door in 91748 and nearby areas. Call (323) 997-8867 and tell us what keys you need.
Do you have a shop I can visit?
No. Crenshaw Lock Company is mobile only, so there is no storefront. Everything happens at your home, office or business.
Can you duplicate keys for a restaurant or plaza suite?
Yes. We work with storefront deadbolts, padlocks, mailbox locks and office keys, and we can handle several suites in one visit. Call (323) 997-8867 to describe the job.
Can you copy a key marked Do Not Duplicate?
That marking is not always a legal barrier, but restricted key systems often require authorization. We will explain what is needed and will not bypass a legitimate restriction.
I have a smart lock. Do I still need a spare key?
Usually yes. Most smart deadbolts keep a mechanical key as backup, and when the battery dies that key may be your only way in. We can copy and test it.
What if my original key is worn out?
A copy of a worn key can inherit its flaws. We may recommend cutting from the lock's code or making a fresh key so the new one works smoothly.
Do you offer key duplication at night or on weekends?
Yes, we are available 24/7. Call (323) 997-8867 at any hour and we will work out a time with you.
Can you make mailbox keys?
In many cases, yes. Bring the lock details or the original key, and we can cut a replacement on location. Tell us about the mailbox type when you call.
