A standard builder-grade deadbolt is designed to keep honest people honest. It is not designed to stand up to someone who knows how to pick, bump or drill a cylinder, and in a dense city like Lynwood, where older single-family homes sit beside large apartment complexes and busy commercial areas, plenty of doors are protected by little more than that. High security locks are a different category of hardware. They use tighter tolerances, more complex internal pin arrangements, hardened inserts that resist drilling, and key blanks that cannot be copied at a hardware-store kiosk.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar brings that experience to every job. We are fully mobile, so there is no storefront to visit. We bring the hardware, assess your door and frame on site, and install the lock that fits your situation, whether that is a single front door in a 1950s bungalow or a full set of cylinders for a medical office.
The lock is only part of the picture. A high security cylinder in a weak door, a loose strike plate or a short screw can undo the benefit. So we look at the whole assembly: the cylinder, the deadbolt body, the strike, the door edge and the frame. Then we explain what we found in plain language, so you decide what makes sense for your property and your budget.
How it works in Lynwood
- 1
Talk through your needs
Call (323) 997-8867 and tell us what you are protecting: a house, an apartment unit, a building with many tenants or a medical office. We ask about your current locks, any recent break-in or key-control concerns, and whether you need keyed-alike or master-keyed cylinders.
- 2
On-site door and frame assessment
Our technician comes to you and inspects the door, the frame, the strike plate and the existing hardware. A high security cylinder performs best in a solid door with a reinforced frame, so we note any weak points before recommending a lock.

Choose the right level of protection
We explain the options in plain terms: pick- and bump-resistant cylinders, drill-resistant hardened components, and restricted keyways where duplicates can only be made with authorization. You choose the approach that fits your property and how many keys you need.
- 4
Install and reinforce
We remove the old hardware and fit the new lock, then address the supporting parts where needed, such as a stronger strike plate, longer screws into the framing or a reinforced door edge. We check the alignment so the bolt throws smoothly and fully.
- 5
Test, cut and hand over keys
We operate the lock repeatedly from both sides, confirm every key works and walk you through how key control works for your system. If you manage multiple units or staff, we help you set up a clear record of who holds which key.

What affects the price
- The grade and brand of the lock itself, since cylinders with more advanced pick-, bump- and drill-resistance cost more than basic upgrades
- How many doors or cylinders are being converted, and whether they can be keyed alike or need a master-key structure
- Whether the door and frame need reinforcement, such as a stronger strike plate, door edge repair or frame work, to support the new lock
- Restricted or patented key systems, which involve controlled key blanks and additional keys for staff, tenants or family
- Time of day and urgency of the visit, since we are available 24/7 and after-hours calls differ from scheduled appointments
- Whether the job also includes related work such as rekeying existing locks, adding security bars or setting up access control
Why Lynwood chooses us
- Fully mobile service: we come to your door in Lynwood with hardware on board, so you are not driving anywhere or waiting at a shop

High Security Locks across Lynwood
Lynwood has a mix of properties that each call for different thinking. Along the Long Beach Boulevard corridor and the Atlantic Avenue corridor, many of the 1960s-80s apartment complexes see regular tenant turnover. For property managers there, high security cylinders with restricted keys make it much harder for unauthorized copies to circulate, and a master-key structure keeps maintenance access manageable while protecting individual units. We can handle back-to-back rekeys and cylinder upgrades as units turn over.
The neighborhoods around Lynwood Park and the older streets of 1920s-50s single-family homes have a different profile. Original doors and frames are often worn, and a break-in nearby is usually what prompts homeowners to act. In those cases a high security deadbolt is often paired with a reinforced strike plate and, where wanted, window and door security bars. If you are in 90262, we can look at the whole entry, from the front door to side and rear access points.
The area around St. Francis Medical Center also has medical offices and clinics with their own needs. Staff changes can mean a master-key system needs to be reset and new cylinders installed so former employees no longer have access. We work with offices like these to design key hierarchies that fit the way the practice operates. Whether you are off I-105, near I-710, along Imperial Hwy or Martin Luther King Jr Blvd, or close to Plaza Mexico and Lynwood City Hall, call (323) 997-8867 any hour.
