Most people think of key copying as a quick errand at a hardware counter, but in Northridge the job is often more involved. A 1960s ranch tract home may have original hardware that has worn smooth over decades, so a copy of a copy can turn out sluggish or fail to turn at all. A student apartment near CSUN may have a stack of keys passed between roommates and subletters. A horse property in Sherwood Forest may need a dozen identical keys for barn, tack room and gate. Our key duplication is built around those realities.

Crenshaw Lock Company is fully mobile. There is no shop to visit; David Shar and our technicians bring the cutting equipment to you, any hour of the day or night, since we operate 24/7. That means you can hand us the original, watch the copy get cut, and test it in your own lock before we leave. If the copy binds, we know right away and can fix the problem on the spot instead of sending you home to try again.

We have served Greater Los Angeles and Ventura County since 1987, and that experience matters for duplication. We can tell when a worn original needs to be cut by code or by a fresh read of the lock rather than copied as is, and when a key is a restricted type that can only be duplicated with proper authorization. Here is how the work goes and what to expect.

How it works in Northridge

  1. 1

    Tell us what needs copying

    Call (323) 997-8867 and describe the keys: front door, mailbox, office, padlock, gate, or a restricted keyway. Tell us how many copies you want and whether the lock has been sticking. That lets us bring the right blanks and equipment.

  2. 2

    We come to your location

    Because we are mobile only, a technician drives to your home, apartment complex, office or property. We are available 24/7, so a late-night request after a lockout or an early-morning one before a move-in is handled the same way.

  3. 3

    Inspect the original and the lock

    Before cutting, we look at the original key for wear and check how it operates in the lock. A badly worn key can produce a poor copy, and a lock with a settled frame can make even a perfect key feel stiff. Spotting this first saves repeat visits.

  4. 4

    Cut and fit the copies

    We cut the new keys on location and test each one in the actual lock. Where needed we deburr and adjust so the key turns smoothly. For mailbox, padlock and office keys, we confirm each copy works with the specific hardware.

  5. 5

    Handle restricted keys properly

    Restricted keyways are protected so copies cannot be made casually. If your key is stamped do not duplicate or uses a controlled keyway, we will talk through what authorization is needed and the proper route to additional keys.

  6. 6

    Final check and advice

    We test every key one more time, tell you if a lock is wearing out, and suggest rekeying or hardware replacement only when it will genuinely help, such as when keys have been lost or too many people hold copies.

What affects the price

  • The type of key: a standard house key differs from a high-security, restricted or specialty key that needs particular blanks and equipment.
  • How many copies you need, since larger batches such as a block of apartment units or a set for a horse property involve more cutting and testing.
  • Condition of the original: a heavily worn key may need to be cut by code or have the lock read directly, which takes more effort than a simple copy.
  • Time and location of the visit, including late-night or holiday service, because we are available around the clock.
  • Whether the lock itself needs adjustment, for example a deadbolt binding in a settled door frame, which adds work beyond the copy.
  • Authorization requirements for restricted keyways, which can affect the steps and materials involved.

Why Northridge chooses us

  • Fully mobile: we cut keys at your door, so you never have to leave a property unattended or drive to a counter.
  • In business since 1987, with owner and lead technician David Shar guiding the standards we work to.
  • Every copy is tested in your actual lock before we leave, not handed over untested.
  • We are upfront about restricted keys and will not cut them without proper authorization, which protects your security.
  • We recommend rekeying or replacement only when it makes sense, not as an automatic upsell.
  • Available 24/7, so urgent copies after a lockout or before a deadline do not have to wait for business hours.

Key Duplication across Northridge

Northridge is a varied place for locks. Around CSUN and the university district, student rentals turn over constantly, and a property manager preparing a complex on Reseda Blvd before fall move-in may need a large batch of keys cut and tested efficiently. We can work through a block of units on site rather than having keys shuttled back and forth. In the Devonshire residential area and Northridge Village, many homes are 1950s and 60s ranch tract houses whose original hardware has seen decades of use, so copies often come out best when we inspect and adjust the lock as well.

The 1994 earthquake that took Northridge's name, with its epicenter in neighboring Reseda, left a documented legacy of frame settling. In some older homes a deadbolt binds because the door and strike no longer line up, and a new key will feel just as stiff as the old one. When we copy keys at a home in ZIP code 91324 or 91325, we check for this and can realign hardware if a stubborn lock is the real problem.

In Sherwood Forest, where horsekeeping estates are common, key needs look different: barn doors, tack rooms and driveway gates, often best keyed alike so one key does the job. We serve those properties and the rest of Northridge, including ZIP codes 91327, 91328 and 91330, from the area near Northridge Fashion Center and Northridge Hospital Medical Center to the stretches along Nordhoff St, Devonshire St, Balboa Blvd and the Ronald Reagan Fwy (SR-118). Call (323) 997-8867 any time.

Key Duplication in Northridge — FAQs

Can you really cut keys at my home or apartment in Northridge?
Yes. We are fully mobile, so we bring the equipment to your door and cut the keys on location. Call (323) 997-8867 and tell us what you need copied.
Do you have a shop I can visit?
No. Crenshaw Lock Company is mobile only, with no storefront. That is deliberate: we come to you, whether you are near CSUN, in Sherwood Forest or anywhere else in Northridge.
Are you available at night or on weekends?
We operate 24/7. If you need an extra key late at night or on a weekend, call (323) 997-8867 and we will arrange service.
Can you copy a key marked Do Not Duplicate?
Those and other restricted keys are protected for a reason. We will not copy them without proper authorization, but we can explain what is required and help you through the correct process.
My old key barely works. Will a copy fix that?
Not always. A worn key makes a poor copy, and in some older Northridge homes the real issue is a door frame that settled after the 1994 earthquake and binds the deadbolt. We check both and can adjust the lock or cut the key more precisely.
I manage student rentals near CSUN. Can you handle many keys at once?
Yes. We can cut and test larger batches on site, and if tenants have changed we can talk through rekeying so old keys no longer work. Call (323) 997-8867 to discuss the number of units.
Can you make matching keys for a horse property?
Yes. For barns, tack rooms and gates, such as in Sherwood Forest, we can set locks to be keyed alike so one key operates them all, then cut the copies you need.
Do you copy mailbox and office keys too?
Yes. We duplicate house, office, mailbox and padlock keys, and we test each copy in the lock it is meant for before finishing the job.
