Installing a lock sounds simple until you meet the door. In San Gabriel the door might be a divided-light wood door on a 1920s bungalow near the Mission, a hollow-core door in a mid-century apartment, or an aluminum storefront on Valley Boulevard. Each one calls for different hardware, different drilling, and a different level of care. A lock that is the wrong size or poorly aligned will bind, wear out early, or fail to secure the door at all.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar and the team bring that experience to every installation. We are fully mobile. There is no storefront to visit, because we bring the tools, hardware and know-how to your door. That works well for new construction, remodels, added rooms, converted garages, side gates, and doors that were never fitted with proper security.

We start by looking at what you actually need: a deadbolt for an exterior door, a keyed entry set for a home office, a privacy lock for a bedroom, or commercial-grade hardware for a shop. Then we install it cleanly, test it, and show you how it works. We are available around the clock, so you can call at any hour.

How it works in San Gabriel

  1. 1

    Tell us about the door

    Call (323) 997-8867 and describe the door: material, thickness if you know it, whether it is interior or exterior, and what you want the lock to do. Photos of the door and frame help us bring the right hardware.

  2. 2

    Assess the door and frame

    On site, we check the door for solidity, the frame for wear or warping, and the clearances around it. Older San Gabriel homes often have doors that have shifted over decades, and we account for that before drilling anything.

  3. 3

    Choose the right hardware

    We go over options for your use: a single-cylinder deadbolt, a keyed knob or lever set, a smart-capable lock, or heavier commercial hardware. We explain tradeoffs plainly so you can pick what fits your door and budget.

  4. 4

    Prepare the door carefully

    We mark and bore the cross-bore and edge holes with proper templates, then cut the strike mortise in the frame. On wood doors, especially period ones, we work slowly to avoid splintering or damaging original finishes.

  5. 5

    Install, align and reinforce

    We mount the lock, set the strike, and confirm the bolt extends fully without binding. Where the frame is weak, we can add a reinforced strike plate with longer screws that reach the framing.

  6. 6

    Test and hand over keys

    We cycle the lock repeatedly, check the door closes properly, and hand over your keys. If you have several doors, we can key them alike so one key works throughout.

What affects the price

  • The type of lock: a basic keyed knob, a deadbolt, a high-security cylinder, or an electronic lock all differ in hardware cost.
  • Door material and condition: solid wood, hollow-core, metal, and glass-panel doors each require different prep work.
  • Whether the door is already bored or needs new holes drilled, which changes labor.
  • Frame condition and any reinforcement needed, such as a heavier strike plate or repairs to a worn jamb.
  • The number of locks and whether you want them keyed alike, which affects hardware and time on site.
  • Residential versus commercial hardware, including storefront and aluminum-frame doors that need specialized parts.

Why San Gabriel chooses us

  • Fully mobile and available 24/7, so installation comes to your door at a time that works for you.
  • In business since 1987, with experience across everything from older wood doors to modern commercial entries.
  • Care with period homes: we know how to work around original wood and avoid unnecessary damage on Craftsman and Spanish Colonial doors.
  • Honest recommendations: we tell you if a cheaper lock will do the job, or if a door needs reinforcement first.
  • Residential and commercial capability, from apartment units to restaurant storefronts.
  • Clean, tested installs with keys handed over and operation explained before we leave.

Lock Installation across San Gabriel

San Gabriel has a mix of door types that rarely appear together in one city. Around the Mission District and the streets near Mission San Gabriel Arcangel, founded in 1771, many homes are 1900s to 1920s Craftsman and Spanish Colonial Revival bungalows. Their doors are often solid wood or divided-light, and adding a modern deadbolt means careful drilling so the original character is preserved. We take our time on these.

Elsewhere, the housing is mostly mid-century single-family homes and apartment buildings, including those off Las Tunas Drive in the Las Tunas area. Remodels, added units and converted spaces frequently need new locks installed where none existed. Along the Valley Boulevard Golden Mile and San Gabriel Boulevard, restaurants and shops rely on aluminum storefronts and roll-gates, which need hardware designed for those frames.

We serve all of San Gabriel, including ZIP codes 91775, 91776 and 91778, whether you are near Vincent Lugo Park, the Mission Playhouse district along Del Mar Avenue, or close to the I-10. Because we are mobile only, we come to wherever the door is. Call (323) 997-8867 any time.

Lock Installation in San Gabriel — FAQs

Can you install a lock on a door that has never had one?
Yes. That is a core part of lock installation. We bore the necessary holes, fit the lock and strike, and test it. Call (323) 997-8867 to describe your door.
Can you install a deadbolt on an older wood door near the Mission?
In most cases, yes. Older wood doors in San Gabriel's historic core need careful drilling and sometimes extra support, and we work to preserve the door's appearance while adding security.
Do you install locks for businesses on Valley Boulevard?
Yes. We handle commercial hardware for storefronts and shops. Call (323) 997-8867 and tell us what kind of door you have, such as aluminum-frame glass or solid.
Can you key several new locks to the same key?
Yes. We can key multiple locks alike so one key works across your doors, which is useful for homes, small offices and multi-unit buildings.
Do you offer installation at night or on weekends?
We are available 24/7. Call (323) 997-8867 any time to discuss your installation.
Do I need to buy the lock first?
You do not have to. We can bring suitable hardware and help you choose. If you have a lock already, tell us the brand and type so we can confirm it fits your door.
How is the price determined?
Price depends on the lock type, door material, whether holes need drilling, frame reinforcement, and how many locks you want. We explain the factors before work begins.
Do you have a shop I can visit?
No. We are fully mobile and come to you anywhere in San Gabriel. Call (323) 997-8867 to get started.
