Most people think of key duplication as a quick stop at a hardware counter. In West Covina that usually means a drive along Azusa Ave or Vincent Ave, a wait in line, and a handful of copies that sometimes turn out not to work. We do it differently. Crenshaw Lock Company is entirely mobile, so the key machine, the blanks and the know-how arrive at your home, office or apartment complex.

That approach matters more than it sounds. A copy of a copy loses accuracy, and a poorly cut key that sticks in the lock gets worse over time. When we cut on location, we can test each new key in the actual lock it is meant for, right then, and adjust before we leave. If a key turns roughly, we fix it while we are standing at your door instead of sending you home to find out.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987 under owner and lead technician David Shar. Key duplication is one of the simplest jobs we do, but we treat it carefully, because every spare key is another way into your property. We also handle the harder cases: restricted keyways that ordinary shops cannot copy, mailbox keys, and office keys that need to be tracked and accounted for.

How it works in West Covina

  1. 1

    Tell us what needs copying

    Call (323) 997-8867 and describe the keys: house, office, mailbox, padlock, or something stamped with a restriction notice. Tell us roughly how many copies you want and where you are in West Covina. Because we are mobile and available 24/7, you can ask at whatever hour suits you.

  2. 2

    We identify the key and keyway

    On arrival we look at the original key and the lock it belongs to. Brand, keyway and condition all matter. A worn original is a poor template, so we point it out and sometimes suggest rekeying or cutting from the lock instead of copying the worn key.

  3. 3

    Confirm authorization for restricted keys

    Restricted and high-security keys are controlled for a reason. If your key is marked do not duplicate or uses a protected keyway, we will talk through what authorization is needed. We will not copy restricted keys for someone who cannot show they are entitled to them.

  4. 4

    Cut the keys on location

    We cut the new keys with our mobile equipment using the right blank for your lock. Brass, nickel-plated and specialty blanks differ, and the correct match affects how smoothly the key works over the years.

  5. 5

    Test every key in the lock

    Each new key is tried in the real lock, several times, including the deadbolt and any secondary latch. If one drags, catches or does not turn fully, we recut or deburr it until it works cleanly. You see it work before we finish.

  6. 6

    Hand over and advise

    We give you the keys and the original, and mention anything we noticed, such as a sticky cylinder or a deadbolt that could use attention. If the number of unknown keys in circulation worries you, we can discuss rekeying so old copies stop working.

What affects the price

  • The type of key: a standard house key is a simpler job than a high-security, restricted or specialty-profile key that needs a particular blank.
  • How many copies you need, since a single spare and a full set for a household or small office are different amounts of work.
  • The condition of the original, because a worn or damaged key may need to be cut by code or from the lock, which takes more time.
  • Whether the key is restricted and requires authorization checks, factory-controlled blanks or additional verification.
  • The time of day you call, since we are available around the clock and after-hours visits are handled differently from daytime appointments.
  • How many different locks are involved, such as a house, a mailbox, a garage side door and an office suite on the same visit.

Why West Covina chooses us

  • Fully mobile: we cut keys at your door, so you never have to leave the house or business to get a spare.
  • Every copy is tested in your actual lock before we leave, not just compared visually to the original.
  • We can handle restricted and high-security keyways, with a straightforward authorization process instead of a flat refusal or a careless copy.
  • Serving Greater Los Angeles and Ventura County since 1987, led by owner and lead tech David Shar.
  • Available 24/7, so a key problem that crops up at night or on a weekend does not have to wait until a shop opens.
  • We will tell you when rekeying makes more sense than copying, such as when a key has been lost or given to someone you no longer trust.

Key Duplication across West Covina

West Covina is a big, varied city and the key work we see reflects that. Much of it is post-war single-family tract housing from the 1950s and 60s, where the original locks have often been through decades of use. Families in neighborhoods like Woodside Village frequently ask for extra house keys for kids, relatives or a dog walker, and worn older locks are exactly where a careful, tested copy pays off. In the South Hills, between the I-10 and SR-60 freeways, view and hillside homes often have higher-end hardware, and some sit behind gates, so matching the correct blank and keyway matters.

Apartment living is another big part of the city. Garden-style and mid-rise complexes near Azusa Ave and Amar Rd generate steady requests for duplicate unit keys, mailbox keys and keys for shared doors. Property managers who want several copies cut at one visit can have us come to the complex instead of sending staff across town. In the 91790, 91791, 91792 and 91793 ZIP codes, we work our way around Glendora Ave, Sunset Ave, Francisquito Ave and Vincent Ave to wherever you are.

Commercial keys matter here too. Plaza West Covina and the Eastland Center area draw a lot of retail, and the medical district near Emanate Health Queen of the Valley Hospital has offices with keys that need careful control. Whether you are a shop owner who needs extra storeroom keys or a household near Cortez Park or Galster Wilderness Park, call (323) 997-8867 and we will come to you.

Key Duplication in West Covina — FAQs

Can you come to my home in West Covina to copy keys?
Yes. We are fully mobile, so we cut keys on location at your house, apartment or business. There is no storefront to visit. Call (323) 997-8867 to arrange it.
Do you offer key duplication at night or on weekends?
We are available 24/7. If you need a spare key outside normal hours, call (323) 997-8867 and we will discuss what you need and when.
Can you copy a key marked Do Not Duplicate?
Those marks do not always mean a key cannot be copied, but restricted keys often have controlled blanks or require authorization. We will explain what is needed before cutting anything, and we do not copy restricted keys for people who are not entitled to them.
Can you duplicate mailbox keys for my apartment complex?
Yes, we handle mailbox keys as well as unit and common-door keys. If you manage a complex off Azusa Ave or Amar Rd and need several copies, call (323) 997-8867 and we can plan a single visit.
My original key is worn. Will the copy work?
A worn original can produce a copy that sticks or fails. We test every new key in the lock, and if the original is too worn we may suggest cutting by code or from the lock, or rekeying. We will explain the options on site.
What affects the cost of key duplication?
Key type, number of copies, condition of the original, restrictions on the keyway and time of day all play a part. We do not quote figures on this page, but we will explain the factors when you call.
Should I rekey instead of copying if I lost a key?
Often yes. A copy gives you another working key, but it does not stop the lost one from working. Rekeying changes the lock so the old key no longer fits. We can discuss both options when you call.
Can you copy high-security keys for South Hills homes?
In many cases, yes, depending on the brand and keyway. Some high-security systems require authorization or special blanks. Tell us the brand when you call and we will tell you what to expect.
