San Dimas is not a cookie-cutter suburb, and the locks on its homes aren't either. Between the 1960s and 70s ranch-style houses, the HOA-managed hillside homes of Via Verde, and the larger lots near San Dimas Canyon and Bonelli Park with barns, outbuildings and gated drives, a home locksmith here sees a wider mix of hardware than in most places. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on showing up prepared for exactly that kind of variety.
Our residential service covers the full life of a home's security: rekeying after you buy or move, replacing worn or damaged deadbolts and knobs, repairing sticky or failing locks, getting you back inside after a lockout, and upgrading to stronger or smarter hardware when you want it. We are 24/7 and entirely mobile. There is no storefront to visit, because the work happens at your door, your gate or your barn.
We try to explain things in plain language. If a lock can be rekeyed and still do its job, we will say so rather than push a replacement. If old hardware is past saving or a door is poorly protected, we will tell you that too, and let you decide what makes sense for your home and budget.
How it works in San Dimas
- 1
Call and describe the situation
Call (323) 997-8867 any hour. Tell us what is happening: a lockout, a new purchase that needs rekeying, a failing deadbolt, or a gate padlock on a rural property. Details like the type of door or lock help us bring the right parts.
- 2
We come to you
Because we are fully mobile, a technician travels to your San Dimas address with tools, key-cutting capability and a range of common residential hardware. We do not make any promises about arrival timing, but we will keep you informed about what to expect when you call.
- 3
Assess the hardware and the door
Before any work begins, we look at the locks, strike plates, door condition and, on larger properties, gates, barn doors and outbuildings. We confirm what is wrong and explain the options in plain terms.
- 4
Rekey, repair, replace or upgrade
We carry out the work you approve. That may mean rekeying cylinders so old keys stop working, swapping a worn deadbolt, repairing a sticking latch, reinforcing a strike plate, or fitting new hardware that matches your HOA or household needs.
- 5
Test everything and hand over keys
We operate each lock repeatedly, check door alignment, and confirm every key works smoothly. You leave with working keys and a clear understanding of what was done and why.

What affects the price
- The type of work: a lockout, a rekey, a repair and a full replacement involve different labor and parts.
- The number of locks involved, such as a single front door versus every exterior door plus a garage entry, side gate and barn.
- Hardware grade and style, including whether you need to match HOA-standard finishes or want higher-security or smart hardware.
- Door and frame condition, since a worn strike or misaligned door may need extra attention to make a lock work properly.
- Property type and layout, as gated drives, padlocked outbuildings and multiple structures can add scope compared with a standard single-door job.
- Time of service, because after-hours, weekend and holiday calls can be handled differently from scheduled daytime work.
Why San Dimas chooses us
- Serving the Los Angeles area since 1987, with David Shar as owner and lead technician.
- Fully mobile and available 24/7, so service comes to your door rather than requiring a trip anywhere.
- Comfortable with the mix of San Dimas properties: ranch homes, HOA hillside communities, small downtown buildings and rural lots with gates and barns.
- Honest recommendations: we rekey when rekeying is enough and only suggest replacement when it actually helps.
- Clear explanation of the work and options before we begin, with no pressure to add things you don't need.
- One company for every lock on the property, from the front door deadbolt to the side gate and barn padlock.
Residential Locksmith across San Dimas
In San Dimas, ZIP code 91773, homes range from 1960s and 70s ranch-style houses along streets off San Dimas Ave and Foothill Blvd to the hillside homes of Via Verde on the southern side of town. A common call there is an HOA-standard rekey after a home purchase: previous owners, agents and contractors may still hold keys, and rekeying the locks while keeping the community's hardware expectations in mind is a sensible first step as a new owner.
Near San Dimas Canyon and Frank G. Bonelli Regional Park, properties are often larger, with horse-keeping zones, barns, outbuildings and gated drives secured by padlocks. We handle barn, gate and padlock service on these properties, whether a lock has seized from dust and weather or you simply want keyed-alike hardware so one key works across the property. Having a mobile technician matters here, since these locks are rarely near the house.
Downtown and Old Town San Dimas, with its western-themed facades along Bonita Ave, has its own small shops and civic buildings. While our focus on this page is residential work, we are familiar with the area and its mix of older and newer doors. Whether you are near Puddingstone Reservoir, close to Arrow Hwy, or just off the 210, 57 or 10 freeways, call (323) 997-8867 any time.
