Most people think of key duplication as a quick errand to a hardware store counter. In Sylmar, that errand can mean a long drive down Foothill Boulevard or a detour onto the I-210 or I-5, only to find the blank doesn't match or the machine produces a copy that sticks in the lock. Crenshaw Lock Company brings the key machine and the know-how to you, so the copy is cut and tested in the lock it is meant to open.

Sylmar is a spread-out community. It runs from tract homes on the valley floor up into the San Gabriel foothills, and it includes gated subdivisions, equestrian properties with barns and outbuildings, and older modest houses. Each of these has different key needs: a gated household may need several matching copies for family members and a house sitter, a ranch may have a tack room, a barn, a trailer and a gate that all need keys, and an office near Olive View-UCLA Medical Center may have keys that need careful handling.

We have served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile and available around the clock, which matters when you discover at night that your only key is the one that just snapped in the lock. This page explains how mobile duplication works, what affects the cost, and what to expect in Sylmar.

How it works in Sylmar

  1. 1

    You call and describe the key

    Call (323) 997-8867 and tell us what you need copied: a front-door key, a mailbox key, an office key, or a key stamped with a restricted or do-not-duplicate marking. Let us know your location in Sylmar and how many copies you want. We will tell you what we may need to see, such as the original key or proof that you are authorized.

  2. 2

    We come to you

    Because we are fully mobile, there is no shop to visit. We drive to your home, ranch, office or parking lot with a key-cutting setup in the vehicle, and we are available 24/7. That means a hillside property or a gated community is handled on site rather than by you running across town.

  3. 3

    We check the key and the lock

    Before cutting, we look at the original key for wear. A key that has been used for decades can produce a copy that is worse than the original. We also test the lock. If the lock is stiff because of dust or a racked door frame, we tell you, because a perfect copy will still struggle in a lock that is binding.

  4. 4

    Cutting on location

    We select the correct blank for the keyway and cut the copy. For restricted keyways, we confirm that you are the authorized holder before proceeding, because these systems exist to control who can have copies. Some restricted or high-security keys cannot be copied by a standard method, and we will say so plainly.

  5. 5

    Testing and fine-tuning

    A fresh cut can be slightly rough. We try each copy in the actual lock several times, smooth any burrs, and confirm it turns without force. If the copy catches, we adjust it instead of handing you something that will wear out your lock.

  6. 6

    Wrap-up and advice

    We hand over the keys and, where it makes sense, suggest practical next steps such as labeling spares, keeping one off-site, or rekeying if you do not know who holds old copies. The choice is yours, and we do not push work you do not need.

What affects the price

  • The type of key: a standard house key is a simpler job than a restricted, high-security, or transponder-style key, which require different blanks and equipment.
  • The number of copies requested, since each additional cut adds a little time and material.
  • Whether the original key is worn or damaged, which can mean extra work to get a copy that operates smoothly.
  • The time of the call: after-hours, overnight and holiday requests are handled by a 24/7 service and may be priced differently from a scheduled daytime visit.
  • Travel across Sylmar's spread-out area, from the valley floor to foothill and large-lot properties, can affect the overall quote.
  • Whether other work is bundled in, such as rekeying a lock, freeing a stiff cylinder, or replacing a padlock on a barn or tack room.

Why Sylmar chooses us

  • Fully mobile service: the key machine comes to your driveway, ranch gate, or office, and there is no storefront for you to visit.
  • Experience dating to 1987 in Greater Los Angeles and Ventura County, with owner David Shar leading the work.
  • We test every copy in the lock it is meant for, rather than handing over a blank-cut key and hoping.
  • We are honest about limits: if a key is restricted, high-security, or legally protected from copying, we say so and explain the proper route.
  • We notice the lock, not just the key, and point out when a racked frame, dusty cylinder, or worn lock is the real problem.
  • 24/7 availability, which helps when a lost or broken key cannot wait until a store opens.

Key Duplication across Sylmar

Sylmar covers a lot of ground, and key needs vary by area. In Rancho Cascades and the other newer gated subdivisions, households often manage keys alongside keypads and call-boxes at the gate. When a home changes hands, a set of duplicate keys for the new owners is a common request, and it is often the right moment to consider rekeying so that old copies no longer work. Around 91342, we handle those requests at the property without you having to leave.

In El Cariso and the foothill areas toward Olive View, many properties are large-lot and semi-rural, with barns, tack rooms, trailers and detached outbuildings. Dust and grit in the air can make padlocks and older cylinders stiff, and a worn key tends to give out first. We can cut fresh copies, and when a lock is too seized to be worth saving, we can suggest a weather-resistant, shrouded replacement. Properties off Hubbard Street, Roxford Street or Foothill Boulevard often have several locks on one property, so having matching or well-organized keys makes a real difference.

Older homes in Sylmar also carry the history of the 1971 and 1994 earthquakes. Settling and racked frames can leave a deadbolt hard to throw, and people often blame the key. Before copying, we check whether the door and strike are aligned, because a new copy will not fix a bolt that no longer meets its strike. Whether you live near El Cariso Community Regional Park, Veterans Memorial Community Regional Park, or close to the Newhall Pass interchange, call (323) 997-8867 any hour.

Key Duplication in Sylmar — FAQs

Do you really come to me in Sylmar to copy a key?
Yes. Crenshaw Lock Company is fully mobile and available 24/7. We bring the key-cutting equipment to your home, ranch, or office in Sylmar, so there is no storefront to visit. Call (323) 997-8867 to arrange it.
Can you copy a key marked Do Not Duplicate?
Often that marking is not a legal barrier, but we are careful with it. We will ask about your authorization and the situation. Restricted keyways are a separate matter and generally require proof that you are the authorized holder.
Can you duplicate restricted or high-security keys?
Some, yes, but not all. Restricted systems are designed to limit copying, and certain keys can only be reproduced through the manufacturer or with specific authorization. We will tell you honestly what is possible once we see the key.
Can you copy mailbox keys?
We can cut copies of many mailbox keys. Keep in mind that postal-owned collection and cluster-box locks are controlled, so we will explain what is appropriate depending on the type of box. Call (323) 997-8867 with the details.
I have barn and tack-room padlocks that are stiff from dust. Can you help?
Yes. Grit can make older padlocks hard to turn and wear keys down. We can cut new copies if the lock is sound, or recommend a weather-resistant, shrouded padlock if it is too far gone.
Why does my new key still not work well in the door?
The lock may be the issue. On older Sylmar homes, settling and quake-related frame racking can misalign the deadbolt and strike. We check that during the visit, and can realign the hardware if needed.
Should I rekey instead of copying keys after buying a home?
If you do not know who holds old copies, rekeying is usually the better step, and then we can cut new copies for your household. Call (323) 997-8867 and we can talk through which option fits.
Do you handle keys for gated properties with keypads?
We can cut the physical keys for the house and outbuildings. Gate keypads and call-boxes are electronic, so we can discuss the access side separately. We do not claim to cover every brand, but we can look at what you have.
