Most people think of key duplication as a quick errand to a hardware counter. In Manhattan Beach, that errand rarely fits the way people actually live. Many homes sit on small lots along walk streets, parking near the Strand can be a chore, and plenty of households are second homes where the person who needs a spare is not even in town. Crenshaw Lock Company is fully mobile, so we bring the cutting equipment to your home, office or building and make the copies on location.

Key duplication covers more than a plain brass house key. We copy standard residential keys, office keys, mailbox keys, and restricted or high-security keys where the system and the proper authorization allow it. Restricted keys are designed so they cannot be copied casually, and we handle them the way they are meant to be handled, which means confirming that you are entitled to the copy before we cut it. That protects you as much as it protects anyone else on the system.

David Shar has run Crenshaw Lock Company since 1987, serving Greater Los Angeles and Ventura County, and the work in a coastal city like this has its own quirks. Salt air wears down keys and cylinders, so a copy made from a badly worn original can inherit its flaws. We check the condition of your original and the lock it operates, and we tell you honestly if a fresh key cut to the code or a lock repair will serve you better than copying a tired key.

How it works in Manhattan Beach

  1. 1

    Tell us what needs copying

    Call (323) 997-8867 and describe the keys: front door, garage side door, office, mailbox, or something stamped as restricted. Tell us how many copies you want and whether you know who originally installed the lock. This helps us bring the right key blanks and cutting tools.

  2. 2

    We come to you

    We are available 24/7 and fully mobile, so we meet you at your home, office or building anywhere in Manhattan Beach. There is no shop to drive to and no need to leave your property, which helps when street parking near the pier or on a walk street is tight.

  3. 3

    Inspect the original and the lock

    Before cutting, we look at your original key for wear, bends and corrosion, and at the lock it operates. A worn key makes a worn copy. If the lock is sticking from salt and sand buildup, we point that out so a new copy does not fail on its first use.

  4. 4

    Verify authorization for restricted keys

    Restricted keys are protected for a reason. If your key falls into that category, we confirm you have the right to authorize a copy and follow the requirements of the system before cutting. Standard house, office and mailbox keys do not need this extra step.

  5. 5

    Cut, test and adjust

    We cut the new keys on location, then test each one in the actual lock, not just on the bench. If a copy binds or turns roughly, we adjust it until it operates smoothly, and we deburr the edges so it does not chew up the cylinder.

  6. 6

    Hand over and advise

    You get your original back along with the new copies. We suggest sensible ways to manage spares, such as how many are enough and when rekeying makes more sense than adding more copies, especially after a housekeeper, contractor or tenant change.

What affects the price

  • The type of key: a basic residential key is a simpler job than a high-security, restricted or electronic-chip key that requires specialized blanks and equipment.
  • How many copies you need and how many different locks are involved, such as front door, side gate, garage and mailbox.
  • The condition of the original: a badly worn or corroded key may call for cutting to the lock's code or servicing the lock instead of copying it directly.
  • Whether authorization steps are required for restricted keyways, which can affect how the job is handled.
  • Whether you want additional work at the same visit, such as rekeying, keying alike, or adding a backup mechanical key to a smart lock.
  • The time of day you call, since we are available around the clock and after-hours visits may be priced differently than daytime ones.

Why Manhattan Beach chooses us

  • Fully mobile service: the cutting equipment comes to your door, so you do not need a trip to a store or any storefront visit.
  • In business since 1987 under owner and lead tech David Shar, with long experience across Greater Los Angeles and Ventura County.
  • We test every copy in the real lock rather than handing over an untested blank-cut key.
  • We are honest when copying is the wrong answer, and will say so if a worn original or a corroded lock means rekeying or repair is the smarter choice.
  • We understand restricted keys and handle them properly, confirming authorization instead of cutting copies without questions.
  • Familiarity with the hardware common here, from small-lot walk-street cottages to custom estates with smart locks and multipoint European-style door systems.

Key Duplication across Manhattan Beach

Manhattan Beach is a small city with very different housing from one neighborhood to the next, and the keys follow suit. In the Sand Section, dense walk-street cottages sit beside newer three-story contemporary homes on narrow lots, often with pedestrian gates and garage access that each have their own key. Salt and sand take a toll on beachfront hardware, so a key that has hung near the Strand for years is often worn smooth. We check it before we copy it, so you do not end up with two keys that both stick.

Up in the Hill Section, large custom estates often mix traditional keyed hardware with smart locks and keypads. A common request there is a backup mechanical key cut after a change in household staff, sometimes paired with reprogramming the keypad. In the Tree Section, mid-century ranch homes are steadily giving way to new builds, and remodels often end with a request to key every door alike so one key does the job. East Manhattan Beach, with its townhomes and condos, brings mailbox keys and shared-entry keys into the mix.

Whether you are in 90266 near Metlox Plaza, off Manhattan Beach Boulevard, along Sepulveda Boulevard, or close to Manhattan Village and Aviation Boulevard, we come to you. If you are near Polliwog Park or Bruce's Beach and need spares before guests arrive, call (323) 997-8867. We are available 24/7 and the work happens at your door.

Key Duplication in Manhattan Beach — FAQs

Do I have to go to a shop to get keys copied in Manhattan Beach?
No. Crenshaw Lock Company is fully mobile with no storefront, so we cut and copy your keys at your home, office or building. Call (323) 997-8867 to arrange it.
Can you copy a key stamped Do Not Duplicate?
That stamp is often just a marking and does not always mean the key is truly restricted. We look at the keyway and the system. For genuinely restricted keys, we confirm you have the authority to request a copy before cutting.
Can you copy mailbox keys?
Yes. We copy mailbox keys on location, including those for townhome and condo clusters in East Manhattan Beach. If the lock is shared or managed by a property manager, we may need their approval for the copy.
My key is worn from salt air. Is it safe to copy?
Copying a very worn key usually produces a copy that works poorly. We inspect it first, and if needed we can cut a fresh key to the lock's code or repair the lock. Call (323) 997-8867 to discuss it.
Can you add a backup mechanical key for my smart lock?
Many smart locks have a mechanical override, and we can cut a backup key for it. If you also want codes changed after a housekeeper or contractor change, tell us when you call and we can plan for both.
Can you make keys for multipoint European-style door hardware?
Often yes, depending on the cylinder and system. Tell us the door brand if you know it, or describe the hardware, and we will let you know what we can cut and what might need servicing.
Is it better to copy keys or rekey after a remodel?
If many people have had access, such as contractors, rekeying and keying all doors alike is usually the better choice, since it makes old keys useless. For simple spares, copying is enough.
Do you offer key duplication at night or on weekends?
Yes, we are available 24/7 and fully mobile. Call (323) 997-8867 any time and we will discuss what you need.
