Most people think of key duplication as a quick errand: walk into a hardware store, hand over a key, walk out with a copy. In Tarzana that errand is rarely that simple. A hillside estate south of Ventura Boulevard may have high-security keys, gate hardware and smart locks that all need to work together. A medical suite on the Boulevard may run on a master-key system where one wrong copy affects an entire floor. And a 1950s ranch home on the flats may carry a mix of builder-grade and later-added hardware that nobody has a record of.

Crenshaw Lock Company is fully mobile. We have no storefront for you to visit, and that is on purpose: our owner and lead technician, David Shar, and our team bring the key-cutting equipment to you, at any hour, every day of the week. We have served Greater Los Angeles and Ventura County since 1987, and the work is the same whether it is a single spare for a mailbox or a set of copies for a growing household.

This page explains how on-location duplication works, what affects the cost, what is different about copying keys in Tarzana, and what to expect when you call. We would rather you understand the process before we arrive than be surprised by it afterward.

How it works in Tarzana

  1. 1

    Tell us what you are copying

    Call (323) 997-8867 and describe the key: a front-door key, a deadbolt key, an office key, a mailbox key, a gate key, or something stamped with a restricted or do-not-duplicate marking. Mention the building type and whether the lock is part of a master-key system. That helps us bring the right blanks and equipment.

  2. 2

    We come to your location

    We are fully mobile and available 24/7, so we travel to your home, suite or property rather than asking you to come to us. We do not make timing promises over the phone that we cannot guarantee, but we will tell you honestly what to expect when you call.

  3. 3

    Verify the key and the right to copy it

    Before cutting, we examine the original key and the lock it operates. For restricted or master-keyed keys, we ask for reasonable confirmation that you are authorized to have copies made. This protects you, your tenants and your building.

  4. 4

    Cut and fit the copy on site

    We cut the new key to match the original, then deburr it and test it in the actual lock. A copy that looks right but sticks or turns roughly is not finished, so we test in the door, gate or mailbox it is meant for.

  5. 5

    Check the original and the lock

    Worn originals produce worn copies. If the original key is badly worn or the lock is sticky, we tell you plainly. Sometimes the better fix is a fresh key cut from the lock itself, or a rekey, instead of copying a copy.

  6. 6

    Hand off and advise

    We give you the finished keys, confirm each one works, and offer practical advice on how many copies to keep and where. If a rekey would make more sense, such as after a staffing or housekeeper change, we explain the option without pressure.

What affects the price

  • The type of key: a basic house key is a different job from a high-security, restricted or sidebar key, which needs special blanks and equipment.
  • How many copies you need, since a set of several keys is handled differently from a single spare.
  • Whether the key is part of a master-key system, which can require added verification and careful cutting to preserve the hierarchy.
  • The condition of the original key, because a worn or damaged key may need to be cut by code or from the lock instead of simply traced.
  • The time of day you call, since we are available 24/7 and after-hours service differs from a scheduled daytime visit.
  • Your location and access, including gated hillside properties where reaching the lock takes extra coordination.

Why Tarzana chooses us

  • We are fully mobile, so there is no trip to a store, no waiting in line and no leaving a door unsecured while you run an errand.
  • We have worked in Greater Los Angeles and Ventura County since 1987, which means we have seen the wide range of hardware found in Valley homes and offices.
  • We handle more than basic keys: house, office, mailbox and restricted keys are all part of the service.
  • We test every copy in the real lock before we leave, instead of handing you a key and hoping it works.
  • We tell you honestly when a copy is not the right answer, such as when a rekey would better address a lost key, a staffing change or a worn lock.
  • David Shar and the team keep the process straightforward, with no dollar figures promised over the phone that we cannot back up.

Key Duplication across Tarzana

Tarzana splits into distinct lock environments, and key duplication looks different in each. South of the Boulevard, in the Santa Monica Mountains hillside near Mulholland Drive and the El Caballero area, many properties are custom or gated estates. Keys here often open high-security cylinders, and a gate or intercom may sit alongside smart locks. A duplicate has to fit into that whole setup, and when a household changes, such as after housekeeper turnover, a rekey is often smarter than another copy.

North of Ventura Boulevard, the Tarzana flats are dominated by 1950s ranch homes and apartments along streets feeding off Reseda Boulevard, Tampa Avenue, Lindley Avenue, Wilbur Avenue and Corbin Avenue. Hardware in these homes is often a patchwork of original builder locks, later upgrades and aging mortise sets. Copies of old keys can be unreliable, so we check the lock as well as the key. Homes in ZIP code 91356 and the surrounding area frequently benefit from this kind of check before a worn key fails for good.

Along the Ventura Boulevard medical and commercial corridor, near Providence Cedars-Sinai Tarzana Medical Center, suites often use master-keyed systems and restricted keys. Duplicating those keys correctly matters for security and accountability. Whether you are in ZIP code 91356 or 91357, near the Tarzana Recreation Center or close to the US-101 on-ramps, we come to you, cut on site and make sure each key works before we leave. Call (323) 997-8867 any time.

Key Duplication in Tarzana — FAQs

Do you really cut keys at my Tarzana home or office?
Yes. We are fully mobile and bring key-cutting equipment to you. There is no storefront to visit. Call (323) 997-8867 and tell us what you need copied.
Are you available outside normal business hours?
Yes, we are available 24/7. If you need a spare key late at night or on a weekend, call (323) 997-8867 and we will work out how to help.
Can you copy a key marked Do Not Duplicate?
Often we can, but restricted and marked keys require verification that you are authorized to have copies. We may also need specific blanks. Call us with details about the key before we visit.
Can you duplicate a master key for my Ventura Boulevard office suite?
Master-keyed systems need care so the key hierarchy stays intact. We confirm your authority to copy, cut precisely and test in the lock. If staffing has changed, we may suggest a rekey instead.
Can you copy a mailbox key?
Yes, mailbox keys are part of our service. We can cut them on site. Some cluster mailboxes are controlled by the postal service or property management, so we may ask about authorization.
My old key is worn. Should I copy it?
Copying a worn key can pass the wear along. We examine the key and the lock, and may recommend cutting a fresh key from the lock or rekeying so you get a copy that works smoothly.
When is a rekey better than another copy?
If a key was lost, a housekeeper or employee left, or you are unsure who holds copies, a rekey makes old keys stop working. Many Tarzana estates and offices choose this after turnover.
How do I get a price for key duplication?
Pricing depends on the key type, the number of copies, whether it is master-keyed or restricted, the key's condition, timing and access. Call (323) 997-8867 and describe the job, and we will explain what applies.
