El Segundo is a town of two very different security needs. West of Sepulveda, the residential grid is full of 1920s to 1940s bungalows and 1950s homes with older hardware, where a worn deadbolt is often the only thing between the street and the front room. East of Sepulveda, the corporate and aerospace campuses and the Smoky Hollow light-industrial district call for access control, master-key systems and tighter control over who holds a key.
High security locks address a specific weakness: standard pin-tumbler cylinders can be picked, bumped or drilled by someone with modest tools and some practice. High-security cylinders use tougher materials, more complex internal geometry and hardened inserts to resist these attacks. Many also use restricted keyways, so a key cannot simply be duplicated at a hardware store kiosk without authorization.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are mobile only, with no storefront, so every job begins with a conversation about what you are protecting and how the door is actually used. Sometimes the best upgrade is a new cylinder; sometimes the door, strike or frame is the weak point and needs attention first.
How it works in El Segundo
- 1
Talk through what you are protecting
Call (323) 997-8867 and tell us about the door, the building and your concerns. A bungalow front door, a multi-suite Smoky Hollow office and a campus interior room each call for different solutions, so we start by understanding yours.
- 2
Assess the door, frame and existing hardware
On site, we look at the whole assembly rather than just the lock. We check the door's fit, strike plate, frame strength and the condition of the current hardware. Older wood doors in west-side bungalows often need realignment or reinforcement for a high-security lock to perform as intended.
- 3
Choose the right level of protection
We explain the options in plain terms: pick-, bump- and drill-resistant cylinders, restricted keyways, and how keys are controlled and duplicated. For commercial clients, we also discuss master-key structure and whether electronic access control makes sense.
- 4
Install and fit the hardware
We install the new locks, adjust the door and strike so the bolt throws smoothly, and make sure the keys operate cleanly. Where an existing lock is corroded or worn, we replace it rather than patch it.
- 5
Test, hand over keys and explain key control
We test every lock repeatedly, hand over your keys and explain how restricted keys are duplicated. For multi-user buildings, we help you set up a sensible record of who holds which key.

What affects the price
- The number of doors or cylinders being upgraded, and whether they need to be keyed alike or on a master-key system.
- The grade and type of high-security cylinder chosen, including whether it uses a restricted keyway with controlled duplication.
- The condition of the door and frame, since realignment, reinforcement or strike upgrades add labor and materials.
- Whether the job is residential, commercial or industrial, and whether electronic access control is part of the scope.
- The time of day and urgency of the request, since after-hours and emergency service differs from scheduled work.
- The number of keys you need cut and any additional key-control or documentation requirements.
Why El Segundo chooses us
- Fully mobile service: we come to your property in El Segundo, so there is no shop to visit and the work is done where the door is.
- Available 24/7, which matters for corporate facilities teams who need after-hours rekeying without disrupting a business day.
- Serving Greater Los Angeles and Ventura County since 1987, with owner David Shar leading the work.
- We assess the door, frame and strike, not just the cylinder, because a strong lock in a weak door does not deliver real security.
- Experience with both older residential hardware and commercial master-key systems, so we fit the solution to the building rather than forcing one product on everyone.
- Straightforward explanations of what each option does and does not protect against, with no inflated claims.
High Security Locks across El Segundo
In the West Side residential grid, many homes are 1930s bungalows and mid-century houses whose original hardware has lived through decades of coastal air. Salt and moisture corrode exterior deadbolts, and doors that have shifted over the years no longer line up with the strike. Upgrading to a high-security deadbolt in ZIP 90245 often goes hand in hand with cleaning up the door fit, so the new lock turns smoothly and the bolt seats fully.
Downtown and Main Street offer a different picture, with small businesses and street-facing storefronts where key control matters as staff change. In Smoky Hollow, creative and light-industrial tenants in multi-suite buildings often want a master-key system and access-control upgrades so each tenant controls their own space while the property manager retains oversight. High-security cylinders with restricted keys help keep those arrangements tidy.
East of Sepulveda, the corporate and aerospace presence, from the area around Los Angeles Air Force Base and the Chevron refinery to Mattel's headquarters and the campuses along Aviation Blvd and Rosecrans Ave, brings heightened expectations for physical security. We can support facilities teams with after-hours rekeying of interior offices and cam-lock service on file cabinets following staff changes. Whether you are near The Point, off Imperial Hwy or close to the I-105, we come to you at any hour on (323) 997-8867.
