Most lock installation calls in La Puente fall into a few familiar groups. A homeowner has turned a garage into a living space and the new door has no lockset at all. A landlord has added an accessory unit behind a 1950s house and wants it secured properly. A shop owner on a busy commercial street has a new or replaced door that needs a cylinder that suits an aluminum frame. In each case the job is the same at heart: fit the right hardware to the door you actually have, and make sure it works smoothly every day.

La Puente is a dense, working-class suburb, and much of it is made up of single-story stucco tract homes built in the 1950s and 60s. Those houses were finished with builder-grade hardware, and over decades doors have been swapped, sanded, repainted, and sometimes warped by the sun. Installing a new lock in one of these doors is rarely as simple as drilling a hole. The door's thickness, the bore, the latch edge, and the strike plate location all need checking so the bolt throws cleanly into solid framing.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile. There is no storefront to visit, because we bring the work to your door at any hour, day or night. Below is how a typical installation goes, what shapes the cost, and what is particular to working in La Puente.

How it works in La Puente

  1. 1

    Tell us about the door

    When you call (323) 997-8867, we ask what the door is made of, whether it is an exterior or interior opening, whether a lock was ever fitted, and what you want it to do. A new ADU door, a garage conversion, and a storefront each call for different hardware, so this conversation sets the plan.

  2. 2

    Inspect the door and frame on site

    We check the thickness, material, and condition of the door and the jamb. On older stucco tract homes we look for warping, sagging hinges, and soft or split framing that could weaken a new deadbolt. Finding these early prevents a lock that binds or fails later.

  3. 3

    Choose hardware that fits the use

    We go over options such as a deadbolt, a keyed entry lockset, or a combination of both, along with grade and finish. If you have several doors, such as a main house and a backyard unit, we can discuss keying them alike so one key works for the set, or keeping them separate.

  4. 4

    Prepare the door and install

    If the door has no bore, we cut the holes and latch mortise to size, using proper templates so the work is clean. We set the lock, fit the strike plate, and reinforce where needed so the bolt engages fully into the frame rather than just the trim.

  5. 5

    Test and hand over keys

    We operate the lock repeatedly with the door open and closed, confirm the bolt throws without forcing, and check that keys work smoothly. You get all the keys, and we explain how to care for the lock so it keeps working well.

What affects the price

  • Whether the door already has a bore for a lockset or needs to be drilled from scratch, which changes how much preparation is involved.
  • The door material, whether solid wood, hollow core, metal, or an aluminum storefront frame, since each needs different techniques and sometimes different parts.
  • The grade and type of hardware you choose, from standard residential deadbolts to higher-security or commercial-grade cylinders.
  • How many locks are being installed and whether they must be keyed alike across several doors, such as a house and an ADU.
  • The condition of the door and frame, including any realignment, reinforcement, or strike repair needed so the new lock works properly.
  • The time of day you call, since we are available around the clock and after-hours visits can be priced differently than daytime ones.

Why La Puente chooses us

  • Fully mobile service: we come to your door with hardware and tools, so there is no trip to a shop and no storefront to find.
  • Operating since 1987 under owner and lead technician David Shar, so the work draws on decades of experience with older Southern California homes.
  • Familiarity with tract-home doors that have shifted or warped over time, so we check alignment before fitting a lock rather than after it binds.
  • Experience with multi-door setups like converted garages and rear units, including keyed-alike arrangements that let one key serve the property.
  • Available 24/7, so a door left unsecured after a remodel or a break-in attempt can be dealt with when it matters, not when a shop opens.
  • Honest recommendations: if a door or frame is too damaged to hold a new lock well, we say so and explain the options.

Lock Installation across La Puente

La Puente sits along the I-10 and SR-60 corridors, and the neighborhoods we visit stretch from Hudson and Sunset to the unincorporated areas of Valinda and Bassett on its edges. Homes in ZIP codes 91744, 91746, and 91747 are largely 1950s and 60s single-story stucco houses on modest lots. Many still carry builder-grade locksets and original doors, so a new installation often goes hand in hand with a quick check of how the door hangs.

Converted garages and accessory dwelling units are common here, and they create new doors that need real locks. A landlord near Amar Road adding a unit behind a main house might want both doors keyed alike so one key works for the property, or separate keying so a tenant never holds a key to the main house. We help sort out which arrangement fits and install it in one visit.

On the commercial side, small shops line Valley Boulevard and the Hacienda Boulevard retail strip, many with aluminum-storefront doors that use pivot hardware and narrow-stile cylinders. If you are opening a space near La Puente Park or the Donut Hole and need a door secured, we can install a cylinder or deadbolt suited to that frame. Call (323) 997-8867 any hour and we will come to you.

Lock Installation in La Puente — FAQs

Can you install a lock on a door that never had one?
Yes. If the door has no bore, we cut the holes for the lockset and latch, fit the hardware, and install a proper strike plate. Call (323) 997-8867 and tell us about the door.
I converted my garage into a living space in La Puente. What lock does the new door need?
It depends on the door and how it is used. Most exterior doors do well with a quality deadbolt plus a keyed entry lockset or handle set. We look at the door on site and recommend something that suits it and your budget.
Can the main house and my ADU use the same key?
Yes, we can install or rekey locks so they are keyed alike, which is convenient for an owner. Landlords often prefer separate keys for the unit. We can set up either arrangement, and you can call (323) 997-8867 to discuss it.
My 1950s home's door is warped. Can a new lock still go in?
Often yes, but we check first. Sun-warped or sagging doors can make a new deadbolt bind, so we may adjust hinges, reinforce the strike area, or advise if the door itself needs attention.
Do you install locks on aluminum storefront doors along Valley Boulevard?
Yes. Aluminum storefront doors use specific cylinders and pivot or deadbolt hardware, and we can install options that fit those frames. Call (323) 997-8867 to describe your door.
Are you available at night or on weekends?
Yes, we are a 24/7 mobile locksmith. If a new or repaired door needs securing outside business hours, you can call at any time.
How much does lock installation cost?
It depends on factors such as whether the door needs drilling, the hardware grade, the number of locks, and the condition of the door and frame. We will talk through these with you before starting work.
Do I need to come to a shop to pick out hardware?
No. We are fully mobile and have no storefront. We bring hardware options to your property and install your choice on the spot.
