Bradbury is a quiet foothill city of large estates, horse properties and long private drives, and the security needs here look different from a typical suburban street. A single property may have a main house, a guest house, a pool house, a barn, a tack room and several gates. Standard builder-grade hardware on all of those doors is a real weak point, especially when a property sits on several acres and the nearest neighbor is out of earshot.
High security locks address that weakness. They use tighter-tolerance cylinders, hardened components and anti-drill protection to resist picking, bumping and forced drilling. Many also use restricted keyways, meaning keys cannot be copied at a hardware store without authorization. That matters on estates where gardeners, house staff, trainers, contractors and tenants may all have held a key at some point.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar leads the work. We are a fully mobile, 24/7 locksmith. There is no storefront to visit; we bring the hardware and tools to your property, assess your doors and gates, and recommend what actually makes sense rather than upgrading everything by default.
How it works in Bradbury
- 1
Talk through your property and concerns
Call (323) 997-8867 and tell us about the property: the main house, any guest house, barn or tack room, and how many gates. We ask who has had keys, whether you have had a break-in or a staffing change, and whether you want keyed, smart or both.
- 2
On-site assessment of every opening
We come to you and look at each door, gate and outbuilding. We check the door and frame, strike plates, existing cylinders and how the hardware is exposed to weather, which matters on ranch gates and barns.
- 3
Choose the right security level
We explain the difference between pick-, bump- and drill-resistant cylinders, restricted keyways and how they compare to standard locks. Main entries may call for the highest grade, while a tack room may need something tough but simpler.
- 4
Install and reinforce
We install the new high security cylinders or deadbolts, and where needed reinforce the strike plate and frame so the lock is not defeated by kicking the door. Everything is tested for smooth operation.
- 5
Key control and handover
We cut and hand over your keys, explain how restricted key duplication works, and can key multiple locks alike so you carry fewer keys across house, gates and barn.
- 6
Follow-up guidance
We leave you with practical advice on who should hold keys, when to rekey after staff or tenant changes, and how to maintain locks exposed to dust, sun and ranch conditions.

High Security Locks across Bradbury
Bradbury, ZIP 91008, sits in the foothills of the San Gabriel Mountains below Angeles National Forest. With about 900 residents, no commercial district, no traffic lights and no sidewalks, it is almost entirely large residential parcels, many of them horse-zoned. Roads like Mount Olive Dr, Royal Oaks Dr, Lemon Ave and Mountain Ave wind between estates, with the I-210 Foothill Fwy close by.
In guard-gated Bradbury Estates, with parcels of roughly five acres or more, a job often means upgrading the main house, guest quarters and pedestrian or perimeter gates together, and arranging entry through the 24-hour guard gate and HOA. On gated Woodlyn Lane, estates of about two acres frequently pair a refined residence with barns, tack rooms and ranch gates that need weather-tough, high security padlocks and deadbolts.
The lower, non-gated part of Bradbury has lots up to an acre and no guard at the entrance, so strong locks and restricted keys carry more of the protection. A common scenario is a whole-property rekey and high security upgrade after a staff or tenant change. Wherever your property sits, we come to you.
