Installing a lock sounds simple until you look at the door in front of you. In Alhambra, that door might be a 1920s Craftsman entry with a solid wood slab, a Spanish Revival front door with decorative hardware, a hollow-core door on a mid-century apartment, or an aluminum storefront door on Main Street. Each one calls for a different approach. The lock has to fit the door, suit the building, and actually keep people out.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar and the team handle new-lock installation as a regular part of the work. Typical jobs include a new deadbolt on a door that only had a knob, locks on a freshly hung door, a gate or side-door lock where none existed, and hardware on a remodel or addition. We are mobile only. There is no shop to visit, so we do the work at your property, whenever you need it.

Because Alhambra is known as the City of Homes, much of what we see is older wood-frame construction where care matters. Drilling a new bore in a century-old door is not something to rush. We look at the door's thickness, its condition, the frame and strike area, and what hardware is already there before we cut anything, so the new lock performs well and the door stays in good shape.

How it works in Alhambra

  1. 1

    Tell us about the door

    Call (323) 997-8867 and describe what you are securing: front door, back door, side gate, garage entry, storefront, or interior room. Tell us the door material, whether it already has a bore hole, and what kind of building it is. That helps us bring the right hardware.

  2. 2

    On-site assessment

    We come to you and inspect the door, jamb and strike area. On a wood bungalow door we check for splitting, thickness and wear. On an aluminum storefront we check the stile width and what the frame can accept. We tell you what will work and what will not.

  3. 3

    Choose the right lock

    We go over options such as deadbolts, handle sets, keyed entry, and higher-security cylinders, and match them to how you use the door. For older homes we talk about finishes and styles that sit well with period character. For rentals and multi-unit buildings, we can discuss keying several locks to work together.

  4. 4

    Precise installation

    We mark, bore and mortise carefully, install the lock, and set the strike plate so the bolt throws fully into solid framing. Where the existing frame is weak, we recommend reinforcement so the lock is only as strong as the wood around it.

  5. 5

    Test and hand over keys

    We operate the lock repeatedly with the door open and closed, check alignment, and confirm it locks smoothly. You get your keys and a quick walkthrough of how everything works, and we can cut extra keys on the spot if needed.

What affects the price

  • The type of door: solid wood, hollow-core, metal, or aluminum storefront, and whether it already has a bore or needs one drilled
  • The grade and style of lock you choose, from basic deadbolts to higher-security cylinders and decorative handle sets
  • The number of locks, and whether they should be keyed alike or kept separate across a building
  • Frame and strike condition, including any reinforcement needed on older or damaged wood
  • Special requirements such as mortise installation on period doors, commercial hardware, or matching existing finishes
  • Timing and location, since after-hours and urgent requests are handled differently than scheduled jobs

  • Careful installation on historic doors, so we avoid unnecessary damage to original wood

Lock Installation across Alhambra

Alhambra's housing tells a story, and it shapes how we install locks here. The Bean Tract and Midwick Tract are among the city's designated historic single-family areas, filled with 1910s to 1930s Craftsman and Spanish or Mediterranean Revival homes. Doors in these neighborhoods are often solid wood with original hardware, and owners usually want upgrades that respect the look of the house. Over in Emery Park and the Airport Tract, we see a mix of bungalows and later homes where adding a deadbolt or securing a side entry is a common request.

The city also has plenty of mid-century apartment and courtyard buildings, where property owners add or replace locks on unit doors, laundry rooms and common areas between tenancies. Around Downtown Alhambra and the Main Street dining and entertainment corridor, near the Garfield Theatre, and along Valley Blvd, mixed-use buildings and aluminum storefronts need hardware that suits narrow stiles and heavy daily use. If you are in 91801 near Main Street or in 91803 closer to the residential tracts, we come to you.

Whether you are off Fremont Ave, near Atlantic Blvd, close to Almansor Park, or just off I-10, we serve the whole city. Call (323) 997-8867 any time of day or night and we will talk through the door and plan the installation.

Lock Installation in Alhambra — FAQs

Can you install a deadbolt on an old Craftsman door in Alhambra?
Usually yes. Solid wood doors in Bean Tract and Midwick Tract homes can generally take a deadbolt if the wood is sound. We inspect the door first and bore carefully. Call (323) 997-8867 to describe your door.
Do you install locks where there was never a lock before?
Yes. We can add locks to new doors, side gates, garage entries, sheds and interior rooms. We measure the door, drill the proper holes and fit the strike so it works correctly.
Can you match the look of my historic home's hardware?
We can discuss finishes and styles that sit comfortably with period homes. Exact matches to original hardware depend on availability, but we will help you choose something appropriate.
Can you install locks on an aluminum storefront door on Main Street?
Yes. We work with commercial and aluminum storefront doors and choose hardware suited to the narrow stile and heavy use. Call (323) 997-8867 so we can plan the right setup.
Can several locks be keyed to the same key?
Yes. We can key multiple locks alike so one key opens them all, or set up separate keys for different doors. This is handy for homes and for apartment owners managing several entrances.
Is the installation available at night or on weekends?
Yes. We are available 24/7 and fully mobile. If a door needs securing urgently, call (323) 997-8867 and we will help.
What affects the cost of installing a new lock?
Mainly the door type, the lock grade and style, how many locks you need, and whether the frame needs reinforcement or extra work. We explain these factors on site before starting.
Do I need to visit your shop to pick a lock?
No. We are mobile only and have no storefront. We bring options to you and help you choose at your property.
