Installing a lock where none existed is different from replacing one. There is no old cylinder to match and no existing bore to reuse, so the details matter: door thickness, edge condition, frame strength, and how the door is actually used every day. In San Dimas those details vary a lot, from a ranch-style house on a larger lot to a small shop in the western-themed downtown to a barn at the back of an equestrian property.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar leads the work. We are fully mobile, so there is no storefront to visit. We come to you, look at the door or gate in person, and install hardware that fits the opening and the way you will use it.

New installs happen for many reasons: a freshly built addition, a converted garage, a new side gate, a workshop that was never secured, or a front door replaced with a slab that arrives with no hardware. Whatever the case, we aim to leave you with a lock that works smoothly, is keyed the way you want, and is set into a door that can actually support it.

How it works in San Dimas

  1. 1

    Talk through the opening

    When you call (323) 997-8867, we ask what is being secured: an entry door, interior room, gate, barn, or shop. We ask about door material, whether it is new or existing, and who needs keys, so we arrive with suitable hardware.

  2. 2

    Inspect the door or gate on site

    We check thickness, material, frame condition, and the strike area. A new lock is only as strong as what holds it, so we point out weak jambs, thin frames, or worn hinges before we drill anything.

  3. 3

    Choose the right hardware

    We go over options such as deadbolts, knob or lever sets, keyed gate locks, and padlock-ready hasps. We explain trade-offs in plain terms, including how each handles weather, which matters for outdoor and barn use.

  4. 4

    Drill, fit, and align

    We bore the door with proper templates, set the latch and bolt, and install the strike plate with screws long enough to reach framing. The goal is a bolt that throws freely without forcing the door.

  5. 5

    Key, test, and hand over

    We test the lock repeatedly with the door open and closed, confirm the keys operate smoothly, and show you how everything works. If you want multiple locks keyed alike, we can set that up.

What affects the price

  • The type of lock chosen, from a basic keyed knob to a higher-security deadbolt or a weather-rated gate lock.
  • Door or gate material, since solid wood, metal, and hollow-core doors each require different prep and fasteners.
  • Whether the opening is already bored or needs fresh holes cut for the lock and latch.
  • Frame or jamb reinforcement needed so the new lock has something solid to hold against.
  • The number of locks and whether they should be keyed alike for one set of keys.
  • Time of day and the distance to your property, since we are mobile and available around the clock.

Why San Dimas chooses us

  • Fully mobile service: we bring the tools and hardware to your door, barn, or gate rather than asking you to come to a shop.
  • Operating since 1987, with owner David Shar leading the work and bringing decades of hands-on door experience.
  • We look at the frame and strike, not just the lock, and tell you honestly if reinforcement would make the install worthwhile.
  • Experience with rural-style setups like barn doors, gated drives, and padlock hardware, as well as standard residential entries.
  • We can match hardware to HOA expectations when a planned community has finish or style standards.
  • Available 24/7, so a door left unsecured after a late move-in or repair does not have to stay that way overnight.

Lock Installation across San Dimas

San Dimas has a mix of building types that call for different installs. The ranch-style homes built in the 1960s and 1970s often have original doors and frames that take new hardware well, but may need a fresh strike plate or reinforced jamb. Around San Dimas Canyon and the larger lots near Frank G. Bonelli Regional Park, we think about barns, outbuildings, and gated drives where weather and padlock-friendly hardware matter as much as the lock itself.

In Via Verde, the planned community on the southern hills, homes tend to follow HOA-standard hardware. If you are adding a lock to a new door or side entry, we can talk through finishes and styles so the installation looks consistent with the neighborhood. In Old Town San Dimas along Bonita Ave, small retail and civic buildings with western-style facades may need locks added to back rooms, storage, or newly built-out spaces.

We serve addresses throughout 91773, whether you are near Puddingstone Reservoir, close to Arrow Hwy and San Dimas Ave, or just off the Foothill Freeway (I-210) or SR-57. Call (323) 997-8867 any hour and we will plan the install around your property.

Lock Installation in San Dimas — FAQs

What is the difference between lock installation and a lock replacement?
Installation adds a lock where none existed, such as a new door, gate, or shed, so the opening may need to be bored and the strike set from scratch. Replacement swaps an existing lock. Call (323) 997-8867 if you are not sure which applies.
Can you install locks on a barn or outbuilding in San Dimas?
Yes. We work with barn doors, sheds, and gates, including properties near San Dimas Canyon. We choose hardware suited to outdoor exposure and can set up padlock-ready hasps or keyed gate locks.
Do you install locks on a brand-new door that came without hardware?
Yes. We check that the door is prepared properly, bore it if needed, and fit the latch and deadbolt. We also check the frame so the new lock is held securely.
Will the new lock match my HOA requirements in Via Verde?
We can discuss finishes and styles with you so the hardware fits the look your community expects. Check your HOA guidelines first, and we will help select suitable options.
Do you install locks for businesses in Old Town San Dimas?
Yes. We can add locks to back rooms, storage areas, or newly built-out spaces along Bonita Ave and elsewhere in town. Call (323) 997-8867 to describe the space.
Can all my new locks use one key?
Often yes. We can key multiple locks alike so one key covers your entry, gate, and outbuilding, depending on the hardware you choose.
Do I need to reinforce the door frame?
Sometimes. If the jamb is thin or damaged, a new lock can be undermined. We inspect it on site and tell you honestly whether reinforcement is worth doing.
Are you available at night or on weekends?
Yes, we are available 24/7 and fully mobile. We do not have a storefront, so we come to your San Dimas property wherever it is.
