Most people think of key duplication as a quick errand: take a key to a hardware counter, wait, and walk out with a copy. In Long Beach that errand is rarely that simple. A Craftsman in California Heights may have keys worn smooth by a hundred years of use. A Naples canal home may have a cylinder that salt air has stiffened until a fresh copy will not turn. A downtown condo may use a restricted key that no hardware counter is allowed to cut. Crenshaw Lock Company brings the equipment to you, so the copy is cut, tested in your actual lock and adjusted on the spot.
We are fully mobile, which means there is no storefront to visit. A technician arrives with key-cutting equipment, a range of blanks and the tools to check how the copy performs in the door it is meant for. That matters more than it sounds. A copy cut from a worn original can inherit the wear and fail within weeks, and testing it in the lock before we leave is the simplest way to catch that. Crenshaw Lock has served Los Angeles and Ventura County since 1987, under owner and lead technician David Shar, and duplication is some of the most routine, useful work we do.
We handle standard house keys, office and commercial keys, mailbox keys and restricted or patent-protected keys where the proper authorization can be shown. Whether you need one spare for a house sitter, a set for a rental turnover or copies for a small office, we can work through it with you and tell you honestly when a worn key should be replaced by a freshly generated one rather than copied again.
How it works in Long Beach
- 1
Tell us what you are copying
Call (323) 997-8867 and describe the keys: front door, deadbolt, office, mailbox, or a key stamped with a do-not-duplicate marking. Tell us the neighborhood and whether the building has an HOA or property manager, since that affects restricted keys.
- 2
We come to your location
Because we are mobile and available 24/7, a technician travels to your home, workplace or building. You do not need to leave a key at a shop or drive across the city with your only copy.
- 3
Inspect the original key and the lock
Before cutting, we look at the key for wear, bends and damage, and check whether the lock itself is sticking, corroded or worn. A copy of a tired key in a tired lock rarely solves the real problem, so we say so before cutting anything.
- 4
Identify the keyway and verify authorization
We match the right blank to your keyway. For restricted systems, we confirm that you are authorized to request copies, which may involve a card, a letter from the property manager or other proof. That protects you and the building.
- 5
Cut, deburr and test in the lock
We cut each copy to the original's code, remove burrs and try it in the actual lock multiple times. If it binds, we adjust or recut. You leave with copies that have been proven in your own door.
- 6
Label, review and advise
We hand over the keys, point out which is which and, if the original is badly worn, suggest whether to retire it. If a lock needs cleaning or a repair, we can talk through that too.

What affects the price
- The type of key: a basic house key is a different job from a high-security, dimple or restricted key that needs special blanks and equipment.
- How many copies you need, since a single spare and a full set for a rental or office are quoted differently.
- Condition of the original: a badly worn key may need to be replaced by code or by decoding the lock instead of simply copying it.
- Authorization requirements for restricted keyways, which can add steps such as verifying a property manager or HOA approval.
- Time and location: after-hours or late-night visits differ from scheduled daytime appointments, and travel depends on where in Long Beach you are.
- Whether lock work is bundled in, such as cleaning a corroded cylinder or repairing an old mortise lock so the new keys actually work smoothly.
Why Long Beach chooses us
- Fully mobile service: the equipment comes to you, so there is no waiting at a counter and no need to hand over your only key.
- Every copy is tested in your lock before we leave, which catches poorly fitting cuts that would otherwise show up at the worst moment.
- Experience with older hardware, including mortise locks on 1920s homes, as well as modern deadbolts, mailbox locks and commercial cylinders.
- Honest advice about worn keys and failing locks, including when a copy is not the right fix.
- Careful handling of restricted keys: we verify authorization rather than cutting anything for anyone who asks.
- Owner-led since 1987 under David Shar, with 24/7 availability across Greater Los Angeles and Ventura County.
Key Duplication across Long Beach
Long Beach is a big, varied city, and the keys in it vary just as much. In California Heights, a designated historic district, and in Belmont Heights, many 1920s Craftsman and Spanish Colonial homes still carry original hardware. Keys for old mortise locks can be thin, worn and hard to match, and we take care to test copies so a fragile lock is not strained. If an original lock is failing, we can discuss repair or a sympathetic retrofit that preserves the look of the door.
Near the water, salt air is the quiet enemy. In Naples, Belmont Shore and along the canals, we see cylinders that have stiffened with corrosion, where a new copy simply will not turn until the lock is cleaned, lubricated or replaced with marine-grade hardware. A homeowner in 90803 might call for a spare key and learn the real issue is the cylinder. We would rather tell you that plainly than cut a key that fails by the weekend.
Farther inland and downtown, the needs shift. Dense apartment buildings in Alamitos Beach and Wrigley (90804, 90813 and 90806 among them) often mean rental turnovers and multiple tenants needing copies. Downtown high-rise condos and converted lofts near Ocean Blvd and the Convention & Entertainment Center usually involve HOA rules and restricted keys. Students near CSULB, offices off Atlantic Ave and the I-710 corridor, and homes in Bixby Knolls all have different needs, and we come to each of them. Call (323) 997-8867 any hour.
