Key duplication sounds like a counter job at a hardware store, but in North Hills it rarely fits that mold. Many homes here are postwar tract houses with decades-old locks and keys that have been copied from copies. Many of the apartments in the dingbats and garden complexes have a mix of deadbolts, mailbox locks and gate keys. Many commercial doors along Nordhoff Street and Roscoe Boulevard use hardware that a big-box kiosk cannot cut. We bring the cutting equipment to you, so the work happens at your door.

Crenshaw Lock Company has been serving Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile and available 24/7. There is no storefront to drive to; the locksmith comes to the property, checks the lock the key is meant to operate, and cuts the copy there so we can confirm it turns smoothly before we leave.

That last step matters. A copy that looks right can still bind, stick or wear out a lock quickly if it was cut from a worn original. When we duplicate on location, we can test the new key in the actual lock, and if the original is badly worn we will tell you honestly whether a fresh key cut by code or a rekey is the better path.

How it works in North Hills

  1. 1

    Tell us what needs copying

    Call (323) 997-8867 and describe the key: a front door key, a mailbox key, an office key, or one stamped with a restricted or do-not-duplicate marking. Let us know how many copies you need and whether it is a house, apartment or business.

  2. 2

    We come to your location

    Because we are fully mobile, a locksmith travels to your home, unit or storefront with a cutting machine and a range of key blanks. You do not need to leave the property or hand your only key to anyone.

  3. 3

    Inspect the key and the lock

    We look at the original for wear and identify the keyway. We also check the lock itself, since a sticky or worn cylinder can make even a good copy hard to use. If something is off, we explain it plainly.

  4. 4

    Verify authorization for restricted keys

    Restricted keyways are controlled for a reason. Before copying one, we need to confirm that you are authorized, such as through the property owner, manager or the registered account for that system.

  5. 5

    Cut, test and adjust

    We cut the copies and try each one in the lock it belongs to. If a key drags or needs smoothing, we adjust it on the spot so you are not left with a copy that works only after jiggling.

  6. 6

    Review options before we leave

    We can suggest sensible next steps, like keeping a spare with someone you trust, rekeying if keys have gone missing over the years, or setting up a master-key arrangement for multiple units.

What affects the price

  • The type of key: a standard house key is simpler than a high-security, restricted or specialty key that needs particular blanks or equipment.
  • The number of copies requested, since more keys mean more cutting and testing time.
  • Condition of the original key, because a worn original may need to be cut by code or replaced rather than traced.
  • Time of day and urgency, as after-hours and same-day requests differ from scheduled daytime visits.
  • Whether additional work is needed, such as rekeying a cylinder, replacing a worn screen-door lock, or servicing a sticking mailbox lock.
  • The scope of a multi-unit job, including how many locks and keys are involved and whether a master-key system is wanted.

Why North Hills chooses us

  • Fully mobile service: we cut keys at your door instead of asking you to bring the only key to a shop.
  • In business since 1987, with owner David Shar leading the work and knowing older residential and commercial hardware.
  • Testing in the real lock, so the copy is checked against the cylinder it will actually be used in.
  • Honest advice on whether a duplicate, a fresh code-cut key or a rekey makes more sense for your situation.
  • Comfortable with apartment and multifamily needs, including mailbox and cluster-box keys and master-key planning.
  • Careful handling of restricted keys, with authorization confirmed before any copy is made.

Key Duplication across North Hills

North Hills, ZIP code 91343, has two quite different lock profiles. North Hills West is mostly 1950s and 60s single-family tract homes, often with a security screen door in front of the main entry. Those screen-door locks wear out, and the house keys have usually been copied several times over. Key duplication here is often a household project: a spare for a family member, a dog walker or a neighbor, tested against a deadbolt that may have been in place for years.

North Hills East is denser, with extensive 1960s and 70s dingbat and garden-apartment buildings and more tenant turnover. For managers and owners, duplication often connects to larger questions: how many keys are out there, which units should be rekeyed, and whether a master-key system would simplify things. Mailbox and cluster-box keys are part of that picture too, and they are easy to overlook until one goes missing.

Along Nordhoff Street, Roscoe Boulevard and Sepulveda Boulevard, small businesses with aluminum-frame glass doors often rely on Adams Rite-style hardware, which calls for the right blanks and know-how. Whether you are near North Hills Community Park, close to the Sepulveda Basin Recreation Area, or off the I-405 corridor, we come to you at any hour. Call (323) 997-8867.

Key Duplication in North Hills — FAQs

Do you really copy keys at my home in North Hills?
Yes. We are a fully mobile locksmith, so we bring cutting equipment and blanks to your house, apartment or business. Call (323) 997-8867 to describe what you need.
Can you duplicate mailbox keys for an apartment building?
Often, yes. Mailbox and cluster-box keys are common in North Hills East apartment buildings. Note that postal-controlled locks may have their own rules, so tell us about the lock when you call.
Can you copy a key marked Do Not Duplicate?
That marking is not always a legal barrier, but restricted keyways are controlled systems. We need to confirm you are authorized before copying one, which may involve the property owner or manager.
Is it better to copy a worn key or have a new one made?
If the original is badly worn, a copy of it may inherit the problem. We can sometimes cut a fresh key by code or recommend rekeying so the new keys work smoothly.
Do you offer key duplication at night or on weekends?
We are available 24/7. If you need keys cut outside normal hours, call (323) 997-8867 and we will talk through the situation.
Can you copy keys for several apartment units at once?
Yes. For multi-unit properties we can duplicate keys, rekey units after tenant turnover, and discuss a master-key system so one key can open multiple doors where appropriate.
How is the price determined?
It depends on the key type, number of copies, condition of the original, timing, and whether other work like rekeying is involved. We explain the factors when you call.
Can you replace a worn security screen door lock while you are there?
In many cases, yes. Screen-door locks on North Hills West single-family homes wear out, and we can often address one during the same visit as your key work.
