Installing a lock where none existed sounds simple, but the result depends on the door, the frame, and how you use the entrance. A new side door, a converted garage, a freshly built custom home, or a gate at the end of a long driveway each calls for different hardware and different prep work. In Walnut, where many homes sit on larger lots, the variety is wide.

Much of the city is single-family tract housing from the 1970s and 1980s, plus newer custom builds. That means we see everything from older solid-core doors that need a clean new bore, to modern doors prepped for smart locks, to gates and barn doors with no real security at all. Our job is to match the lock to the opening instead of forcing a one-size-fits-all product onto it.

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, with no storefront to visit. We bring the work to you, whether you are in Walnut Heights, inside Snow Creek, or near the Mt. San Antonio College area.

How it works in Walnut

  1. 1

    Tell us about the opening

    Call (323) 997-8867 and describe what you are securing: an entry door, interior room, side gate, barn door or garage access. Tell us the door material, whether it is already drilled, and whether you want a keyed deadbolt, keypad, or smart lock.

  2. 2

    Assess the door and frame

    On site, we check door thickness, material, and condition, and whether the frame can hold a strike plate and long screws properly. A strong lock in a weak frame is only half a solution, so we point out any reinforcement needed.

  3. 3

    Choose the right hardware

    We go over options that fit your situation, such as a standard deadbolt, a keypad, a smart lock that works with your phone, or a heavy-duty gate latch. We explain the tradeoffs plainly so you can decide.

  4. 4

    Prepare and install

    If the door has no bore holes, we cut them cleanly with proper tools to avoid splitting the door. We then mount the lock, set the latch and strike, and reinforce the frame where needed so everything lines up and closes smoothly.

  5. 5

    Test and hand over keys

    We operate the lock repeatedly with the door open and closed, confirm the bolt fully engages, and set up any codes or app access. You receive your keys and a quick walkthrough before we leave.

What affects the price

  • The type of lock chosen: a basic keyed deadbolt differs considerably from a keypad or app-connected smart lock.
  • Whether the door is already drilled or needs new bore holes cut from scratch.
  • Door material and condition, since solid wood, steel, fiberglass and older doors each take different prep.
  • Frame reinforcement, such as strike plates, longer screws, or reinforcing hardware.
  • The number of locks, and whether they should be keyed alike so one key works throughout.
  • Specialty applications like driveway gates, barn doors, or commercial-style institutional doors, which use different hardware.
  • Time of day, since after-hours and weekend calls can affect how a job is scheduled and quoted.

Why Walnut chooses us

  • Fully mobile service: we come to your door in Walnut, so the install happens on your actual door rather than guesswork.
  • Since 1987 in the Los Angeles area, with owner David Shar directly involved in the work.
  • Experience with both traditional hardware and smart or keypad locks common in newer Walnut homes.
  • Willingness to look at the whole opening, including frame and strike, instead of just bolting on a lock.
  • Familiarity with gate and barn hardware for larger-lot and equestrian properties in the hills.
  • Available 24/7, so urgent installs after a break-in, move-in, or renovation do not have to wait.

Lock Installation across Walnut

Walnut sits between the San Jose Hills and the Puente Hills, and its housing reflects that mix of suburban and semi-rural living. In Walnut Heights, many homes are tract-built single-family houses on generous lots, where we often add deadbolts to side doors, secure converted garage entries, or upgrade older hardware. Inside the gated community of Snow Creek, homeowners frequently want smart locks or keypads that pair well with existing gate-access routines, and we can install and set those up at the door.

We also work near the Mt. San Antonio College area, where rental rooms, small offices and student-oriented housing sometimes need new locks on additional doors. In the hillside pockets where horses are kept, barn doors and driveway gates often have little more than a hook or a basic latch, so we can install sturdier gate and barn hardware suited to outdoor weather.

Whether your property is in ZIP code 91789 or 91788, we come to you from wherever we are working, reaching Walnut via SR-60, SR-57, Grand Ave, Valley Blvd, Lemon Ave, Amar Rd, Nogales St or Pierre Rd. Neighbors near Suzanne Park and Creekside Park can reach us any hour at (323) 997-8867.

Lock Installation in Walnut — FAQs

Can you install a lock on a door that has never had one?
Yes. We cut the bore and edge holes properly, mount the latch and strike, and reinforce the frame as needed. Call (323) 997-8867 to describe the door and we will plan the right hardware.
Do you install smart locks at Snow Creek homes?
Yes, we install and set up keypad and smart locks for homes in Snow Creek and elsewhere in Walnut. We help configure codes or app access before we leave so you can use the lock right away.
Can you secure a barn or driveway gate on a hillside property?
We can. Equestrian and larger-lot properties in the Walnut hills often need weather-resistant gate latches or barn door locks, and we select hardware that suits the gate and how it is used.
Do I need to buy the lock first?
Not necessarily. We can recommend and supply hardware that fits your door, or install a lock you already purchased if it suits the opening. Call (323) 997-8867 if you are unsure.
Will drilling damage my door?
Done with the right tools and a careful layout, a new bore is clean and tight. We check the door material first so we can prepare it without splitting or weakening it.
Do you offer lock installation outside business hours?
Yes. We are 24/7 and fully mobile, so urgent installs after a break-in, a move, or a repair are possible at any hour.
Can all my new locks use the same key?
In most cases yes. We can key multiple locks alike so one key works throughout, which is convenient for a home with several entry points.
Do you have a shop I can visit in Walnut?
No. Crenshaw Lock Company is entirely mobile, so we come to your home, gate or property in Walnut instead of operating a storefront.
