Copying a key sounds like the simplest job in the lock trade, but in Westmont it is rarely just a matter of running a blank through a machine. Many homes here are small stucco and California bungalows built between the 1920s and 1950s, and plenty of their locks have been turning for decades. A worn original key makes a worn copy, and a copy of a copy can drift far enough from the factory cut that it sticks, binds, or fails in the cylinder. We take that into account whenever we duplicate a key.
Crenshaw Lock Company is fully mobile. There is no storefront to drive to. Our technician comes to your home, duplex, apartment building or business, brings the key-cutting equipment, and makes the copies on location. That means you can test every new key in the actual lock before we leave, which is the only real way to know a copy works. It also means you do not have to hand a key to a stranger at a counter and hope for the best.
The service covers more than standard house keys. We copy office keys, mailbox keys, and many restricted keys that hardware-store kiosks will not touch. Owner and lead technician David Shar has been in this trade since 1987, and the company has worked across Greater Los Angeles and Ventura County for all of that time. If your key will not copy cleanly, we will explain why and tell you whether rekeying or a new lock makes more sense.
How it works in Westmont
- 1
You call and describe the key
Call (323) 997-8867 at any hour. Tell us what kind of key it is: house, office, mailbox, or one stamped with a restriction such as Do Not Duplicate. Mention how many copies you need and the address in Westmont. Honest details up front help us bring the right blanks and equipment.
- 2
We come to you
Because we are mobile, the work happens at your home, rental unit, or commercial space. Whether it is a bungalow off Vermont Avenue or a unit in a strip along Western Avenue, you do not need to travel anywhere or leave the property unattended.
- 3
Inspect the original key
Before cutting, we look at the key you want copied. Heavy wear, bent shoulders, or rounded cuts are common on keys from older Westmont homes. If the original is badly worn, we may suggest cutting from a better reference or rekeying the lock so the new keys match a fresh, accurate pin pattern.

Identify restricted or special keys
Restricted keys are controlled systems, so we check what you have and who is authorized to request copies. Some can be duplicated with proper authorization, and others cannot be copied at all. We will tell you plainly which category yours falls into rather than guessing.
- 5
Cut and match the blank
We select the correct blank for the lock brand and keyway, cut the copy, and remove burrs so the key slides smoothly. Matching the blank matters on older hardware, where a close-but-wrong keyway can catch or wear the pins.
- 6
Test in the lock
Every copy is tested in the actual lock, front door, deadbolt, gate or mailbox, before we consider the job done. If a copy hesitates or sticks, we adjust or recut it on the spot.

What affects the price
- The type of key: a standard house key is a different job than a high-security, restricted or specialty key that needs particular blanks or authorization.
- The number of copies requested, since more keys mean more cutting and testing time.
- The condition of the original, because a worn or damaged key may need extra work, a better reference, or rekeying instead of simple duplication.
- Whether the lock itself needs attention, such as a sticking cylinder on an older bungalow door that should be serviced before new keys are cut.
- The time of day and the location of the call, since we are available 24/7 and after-hours service is handled differently than a scheduled visit.
- The hardware involved, such as commercial cylinders, gate locks or mailbox locks, which can require different blanks or tooling.
Why Westmont chooses us
- Fully mobile: the keys are cut at your door and tested in your own lock, so there is no counter handoff and no guesswork.
- In business since 1987, with owner David Shar leading the work and decades of familiarity with older residential hardware.
- We handle restricted and specialty keys, not just standard house keys, and we are upfront about what can and cannot be duplicated.
- We recommend rekeying when it is the better answer, for example after tenant turnover in a duplex, instead of selling you extra copies of keys you cannot account for.
- Available 24/7, so a lost or locked-away spare is not stuck waiting for store hours.
- We can cover related needs on the same visit, from reinforced strike plates on a 1940s door to locks on a roll-down security gate.
Key Duplication across Westmont
Westmont is an unincorporated community in Los Angeles County, and its housing tells you a lot about the keys we copy. In the 90047 ZIP code and the blocks around the Vermont Avenue corridor, you find dense rows of older single-family homes, small stucco bungalows on modest lots, plus duplexes and small apartment buildings. Many of those doors still carry original or decades-old hardware. Copies for family members, a house sitter, or a caregiver often need a careful hand, because the cylinders inside have seen a lot of use.
Along the Western Avenue corridor and the Imperial Highway commercial strip, the picture changes. Mini-malls, markets and auto shops are common, and many are secured with roll-down gates and padlock or cylinder locks. Business owners often need duplicate keys for employees, a manager, or a landlord, and need them cut without closing up shop. A mobile visit lets us handle it at the storefront. The same goes for properties near Jesse Owens Community Regional Park on South Western Avenue, in the 90044 ZIP code, and for residents near Washington Preparatory High School.
We also work with landlords and tenants around Vermont Knolls and West Athens, which border Westmont. Rental turnover is a frequent reason for a call: a duplex or apartment unit changes hands, and the owner wants fresh keys for the new tenant rather than trusting that old copies are all accounted for. With Western, Vermont, Manchester, Florence and Imperial all running through the area, we can reach most of Westmont directly, any hour of the day or night.
