A spare key is one of those small things that feels unimportant until the day it matters. In Mission Hills, where many homes have been lived in for decades, the key that opens the front door is often a worn copy of a copy. Each generation of duplication drifts a little from the original cuts, and eventually the key sticks, wobbles in the cylinder, or snaps off in the lock. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and fresh, accurate duplication is one of the simplest ways we help neighbors avoid a bigger problem later.

We are a fully mobile locksmith, which means there is no counter to walk up to. Our technician comes to your home, office or property with the cutting equipment and key blanks needed to do the work on the spot. That matters for people who cannot easily leave a business, for older residents, and for anyone who would rather not hand a house key to a stranger at a kiosk. You watch the key being cut, test it in your own lock, and keep the original in your hand the whole time.

Duplication is not the same for every key. A standard house key is straightforward. A mailbox key, a restricted or patent-protected key, a worn original, or a key for a high-security cylinder each calls for different handling. We will tell you honestly what can be copied on location, what requires proof of authorization, and when the better answer is rekeying the lock instead of copying a key you no longer fully trust.

How it works in Mission Hills

  1. 1

    Call and describe your keys

    Reach us at (323) 997-8867 any hour. Tell us what kind of keys you need copied: front door, deadbolt, mailbox, office, padlock, or something stamped with a restricted keyway. A photo of the key and the brand name on the lock helps us arrive with the right blanks.

  2. 2

    We come to you

    Because we are fully mobile, the work happens at your Mission Hills home or business. There is no shop to visit. We bring cutting equipment and a range of blanks so most standard copies can be finished in one visit.

  3. 3

    Inspect the original key and lock

    Before cutting, we look at the original. A badly worn key makes a poor master for a copy, and a sticking lock may be the real culprit. If the original is too worn, we may recommend making a new key from the lock itself or rekeying so the new keys fit cleanly.

  4. 4

    Cut and match the blank

    We select the correct blank for the keyway, cut it, and deburr the edges so it does not shed metal shavings into your cylinder. Mailbox and cabinet keys are handled the same way, with the right blank for each.

  5. 5

    Test in the actual lock

    Every duplicate is tried in the lock it is meant for, several times, in both locked and unlocked positions. If a copy binds or catches, we recut or replace it instead of leaving you with a key that nearly works.

  6. 6

    Restricted keys and authorization

    Restricted keyways are designed so copies are not made casually. For these, we will talk through what authorization is needed and what can be done, and we will not bypass the protections that your property manager, employer or lock owner set up.

What affects the price

  • The type of key: a basic house key differs from a high-security, restricted or transponder-style key in blank cost and cutting effort.
  • How many copies you need, since multiple keys cut during the same visit are more efficient than separate trips.
  • The condition of the original, because a worn or damaged key may need extra work or a different approach to get an accurate copy.
  • Whether the key is restricted and requires authorization checks or special blanks.
  • Time of day, since we are available 24/7 and after-hours or urgent visits are scheduled differently from a planned daytime appointment.
  • Whether other work is added on the same visit, such as rekeying, a deadbolt upgrade or lock repair.

Why Mission Hills chooses us

  • Fully mobile service: the keys are cut at your door, so you never have to leave a home or office unattended to get a spare.
  • In business since 1987, with owner and lead technician David Shar behind the work.
  • Honest advice about when copying is the wrong answer, such as when a key has been lost or a former tenant or employee may still hold one, and rekeying is safer.
  • Every copy is tested in your own lock before we finish, rather than handed over untested.
  • Respect for restricted keys: we explain authorization requirements plainly and do not work around the security your lock was installed to provide.
  • Familiarity with the mid-century cylinders and older mortise hardware common in Mission Hills homes, where worn keys are a frequent cause of trouble.

Key Duplication across Mission Hills

Mission Hills has an unusual mix of old and ordinary. Around the Historic Mission district, near Mission San Fernando Rey de Espana and the Andres Pico Adobe, you find quiet streets of late-1940s to 1960s stucco ranch and minimal-traditional homes, with some Spanish-influenced and mid-century houses mixed in. Many still carry their original cylinder locks, and a few older homes retain mortise locksets. Keys that have been copied again and again over the years are common here, and fresh duplication from a clean original can restore smooth operation to a lock that has been fighting you.

The Dennis Park tract has its own long-settled feel, with homeowners who tend to keep spare keys with family, neighbors and house cleaners. That is a good moment to ask whether every key still out there should be. Along the Sepulveda Boulevard corridor and near Providence Holy Cross Medical Center, small professional and medical offices have different needs: extra keys for staff, mailbox keys, and sometimes a conversation about whether a rekey makes more sense after people have come and gone. Properties in ZIP code 91345 are served the same way, by a technician who drives to you from wherever the road, whether Sepulveda, San Fernando Mission Boulevard, Brand Boulevard or the CA-118, happens to lead.

When you are buying or selling a home near the Mission, duplication often pairs naturally with a rekey. Rather than collecting copies of keys you cannot account for, many owners choose to have the exterior cylinders keyed alike to a new set and then cut the spares they need. We can do both in one visit. For historic-adjacent homes, we also take care to work around vintage doors and hardware without unnecessary damage.

Key Duplication in Mission Hills — FAQs

Can you really cut keys at my Mission Hills home?
Yes. We are fully mobile and bring cutting equipment and blanks to your door. Call (323) 997-8867, and we will confirm what we need to know about your key before heading out.
Do you have a shop I can visit?
No. Crenshaw Lock Company is mobile only, so there is no storefront. All duplication is done on location at your home, office or property.
Can you copy a key marked Do Not Duplicate?
That marking is not always a legal barrier, but it often signals a restricted or controlled system. We discuss authorization with you first and will not bypass the protections that a property owner or employer has put in place.
My key is badly worn. Will a copy work?
A copy of a worn key inherits the wear, so it may bind or fail. We inspect the original first and may suggest making a new key from the lock or rekeying so the new keys operate smoothly.
Can you duplicate mailbox keys?
Yes, most standard mailbox keys can be copied on location. If the mailbox is a communal or controlled unit, we may need to confirm authorization. Call (323) 997-8867 with the details.
Should I copy a key or rekey the lock?
If you know exactly where every key is, copying is fine. If a key was lost, or a former tenant, employee or contractor may still have one, rekeying is usually the safer step. We can advise on either.
Do you copy keys for older homes with mortise locks?
Often yes. Older Mission Hills homes sometimes have mortise locksets with their own key styles. We assess the lock first, and if it is failing we can discuss repair or a sympathetic upgrade.
Are you available outside normal hours?
Yes, we are available 24/7. For planned duplication you can schedule at your convenience, and for urgent needs call (323) 997-8867 at any hour.
