A spare key is one of those small things that feels unimportant until the day it matters. In Glendora, that day tends to arrive at inconvenient moments: a teenager heading to Citrus College without a house key, a contractor who needs temporary access to a hillside home, or a shop owner in the Village who has only one key to the front door. Having a reliable copy, cut properly the first time, saves a lot of those headaches.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business around coming to the customer. We are fully mobile, so key duplication happens at your home, office or storefront rather than at a counter. You can watch the key being cut, test it in your own lock, and make sure it turns smoothly before we leave.

Our duplication work covers standard house keys, office and commercial keys, mailbox keys, and restricted or patented keys that most hardware-store machines will not touch. Because we are on location, we can also look at the lock itself. A copy that is cut well but runs against a worn or gritty cylinder will still stick, and we would rather tell you that on the spot than hand you a key that fails in a month.

How it works in Glendora

  1. 1

    Tell us about the key and the lock

    When you call (323) 997-8867, we ask what kind of key you have: a house key, an office key, a mailbox key, or one stamped with a restricted or do-not-duplicate marking. Knowing the brand, where the lock is, and how many copies you need helps us arrive with the right blanks and equipment.

  2. 2

    We come to your location

    Because we are 24/7 and fully mobile, we travel to your home, workplace or storefront in Glendora. There is nothing to drop off and no store to visit, which matters if you only have one working key and cannot afford to part with it.

  3. 3

    Identify the key and check the original

    We confirm the keyway and look at the condition of your original. Keys that are worn, bent or previously copied from a copy often produce poor duplicates, so we inspect before cutting and let you know if a better approach, such as cutting by code or originating a fresh key, makes more sense.

  4. 4

    Cut the copy on site

    We cut the new key using the correct blank and a precise process, then deburr it so it does not catch or shed metal shavings in your lock. For restricted keys, we confirm authorization requirements before proceeding, since those systems exist to control who can copy a key.

  5. 5

    Test it in the real lock

    Every copy is tried in the actual lock it is meant for, usually several times, in both the locked and unlocked directions. If it binds, we adjust it or address the cylinder itself, which is common on locks clogged with dust and grit.

  6. 6

    Review spares and next steps

    Before we wrap up, we talk through how many copies you actually need and who should hold them. If a key has been lost or given to someone you no longer trust, 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, dimple, or restricted key that requires special blanks and equipment.
  • The number of copies requested, since cutting several keys in one visit is different from a single copy.
  • Whether the key is restricted or patented, which can involve authorization steps and specialty blanks.
  • The condition of the original key and lock, because a worn original may call for cutting by code or servicing the cylinder.
  • Whether key duplication is paired with other work, such as rekeying or cylinder repair, during the same visit.
  • The time of day and the location of the service call, since we operate 24/7 and travel to you.

Why Glendora chooses us

  • We are fully mobile, so copies are cut at your door and tested in your actual lock, rather than at a counter where you never see how the key performs.
  • We have served Greater Los Angeles and Ventura County since 1987, so we have handled everything from basic tract-home keys to older hardware in historic buildings.
  • We can handle restricted keys properly, following authorization requirements rather than cutting around them.
  • Because a technician looks at the lock as well as the key, we can flag worn or grit-fouled cylinders that would make any copy feel rough.
  • We are available around the clock, which helps when a single remaining key is the only thing between you and a locked house or shop.
  • We stick to straightforward advice: if a rekey or a new key would serve you better than another copy of a worn one, we say so.

Key Duplication across Glendora

Glendora covers a range of properties, and key needs differ across them. In North Glendora, many of the foothill estates and custom hillside homes are mid-century or newer builds, some set behind gates or at the end of long private drives. These homes often use higher-end hardware such as Baldwin and Emtek sets and multipoint patio door locks, which can have keys that are less common than the standard kind. Coming to the property means we can work with those locks directly instead of asking you to carry unusual keys around town.

In Glendora Village, the historic downtown has early-1900s buildings and boutique storefronts where one key often serves a whole business. Shop owners near the Village can have us cut spare keys for staff or a landlord without closing the doors, and we can check whether an older cylinder is wearing out. Further south, South Glendora is mostly post-war single-family tract housing, where families commonly need extra house keys for kids, relatives or pet sitters. Whether you are in ZIP code 91740 or 91741, the service works the same way: we come to you.

Local conditions matter too. Homes near the foothills and trailheads of Big Dalton Canyon deal with dust and grit after Santa Ana wind season, and that grit can make a freshly cut key feel stiff in a dirty lock. If we notice this, we can talk about cleaning or rekeying. Easy access from Interstate 210, Foothill Blvd along historic Route 66, Grand Ave, Glendora Ave and Lone Hill Ave means we can reach most parts of the city, from near Citrus College to the neighborhoods around Glendora Country Club.

Key Duplication in Glendora — FAQs

Do you really cut keys at my house in Glendora?
Yes. We are fully mobile, so we bring the equipment to your home, office or storefront. There is no shop to visit. Call (323) 997-8867 and tell us what kind of key you need copied.
Can you copy a key marked 'Do Not Duplicate'?
That marking does not always mean a key cannot be legally copied, but it is a signal to be careful. We follow authorization requirements for restricted and patented key systems. Call (323) 997-8867 and we can explain what is needed for your specific key.
Are you available at night or on weekends?
Yes, we operate 24/7. If you have a single key left and need a spare right away, you can reach us at any hour and we will arrange a visit.
Can you duplicate keys for high-end hardware on a North Glendora home?
Often, yes. Many hillside and foothill homes use brands like Baldwin and Emtek or multipoint patio door locks. Tell us the brand and lock type, and we will confirm what we need before we arrive.
My copy of a copy does not work well. Why?
Each generation of copy can lose a little accuracy, especially when the original is worn. We can inspect your key and, if needed, cut by code or make a new key so you are not relying on a degraded pattern.
Can you make extra keys for my Glendora Village shop?
Yes. We can cut spare keys for storefronts, back doors and mailboxes on site, so you do not have to close up. We can also check older cylinders for wear while we are there.
Why does my new key stick in a lock after wind season?
Dust and grit from Santa Ana winds can build up inside a cylinder, which makes even a perfect copy feel rough. We can look at the lock and recommend cleaning, repair or rekeying. Call (323) 997-8867 to set up a visit.
Should I rekey instead of just copying a key?
If a key was lost, or someone who no longer needs access has a copy, rekeying is usually the better choice because it makes old keys stop working. If you simply want more copies for trusted people, duplication is enough.
