Installing a lock where none existed before is a different job from swapping a worn one. It means checking the door itself: its thickness, its edge, its material, and whether it can hold a bore and latch without weakening. A good installation starts with the door, not the hardware box. That is how we approach every job in Norwalk.

Much of Norwalk was built during the post-war aerospace boom, and those single-story stucco ranch and minimal-traditional homes have seen decades of additions. Converted garages, new side doors, enclosed patios, back-house entries and replacement slab doors often get hung with no lock at all, or with a cheap latch that was never meant to secure anything. We install proper deadbolts, entry sets and secondary locks on those openings so they match the security of the main door.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, under owner and lead technician David Shar. We are fully mobile, with no storefront to visit. We bring the tools and a range of hardware to your door, explain the options plainly, and install what suits the door and how you use it.

How it works in Norwalk

  1. 1

    Talk through the opening

    Call (323) 997-8867 and tell us what the door is: wood, hollow-core, metal, or an aluminum slider. Describe whether it is an entry, a garage conversion, a gate or an interior room. This helps us bring suitable hardware.

  2. 2

    Inspect the door and frame

    On site we check the door's thickness, condition, edge and frame. A hollow-core door or a thin, split jamb may need reinforcement before a deadbolt will do any real good, and we say so up front.

  3. 3

    Choose hardware that fits

    We go over deadbolt grades, handle sets, keyed-alike options so one key can work several doors, and whether you want a keypad or smart option. You decide with clear information, not pressure.

  4. 4

    Drill, fit and align

    We mark and bore the door with proper templates, cut the edge for the latch, and set the strike plate in the frame. Careful alignment matters because a deadbolt that binds will wear out early or stop being used.

  5. 5

    Reinforce where needed

    Where the frame is weak, we can add a longer strike plate with long screws that reach the framing behind the jamb, which is where forced-entry strength actually comes from.

  6. 6

    Test and hand over keys

    We cycle the lock repeatedly with the door open and closed, confirm it throws fully, and hand over your keys. We also show you how any extra features work before we leave.

What affects the price

  • The type of door: solid wood, hollow-core, metal or an aluminum slider each need different preparation and different hardware.
  • Whether the door is already bored for a lock or needs fresh holes and an edge cut from scratch.
  • The grade and brand of hardware you choose, from basic deadbolts to higher-security or electronic locks.
  • How many locks are being installed, and whether they should be keyed alike to share one key.
  • Frame condition, including any reinforcement, strike plate upgrades or jamb repair needed for a solid result.
  • Time of day and the location of the job, since we operate 24/7 and some visits happen after hours.

Why Norwalk chooses us

  • Fully mobile service: we come to your door in Norwalk, so there is no shop trip and no need to take the door off its hinges.
  • Serving Greater Los Angeles and Ventura County since 1987, so we are familiar with the mid-century doors and frames common in Norwalk.
  • We evaluate the door and frame before recommending anything, and we tell you honestly when a door needs reinforcement first.
  • Experience with both single-family tract homes and older multi-unit buildings, including aluminum sliding patio doors on original latches.
  • Owner-led work under David Shar, with clear explanations of options rather than a one-size-fits-all install.
  • Available around the clock, so a new door or a gap in security does not have to wait until business hours.

Lock Installation across Norwalk

Norwalk's housing tells you a lot about what installation jobs look like here. Around Carmenita Road and the neighborhoods near Cerritos College and Studebaker Road, many 1950s stucco tract homes now have converted garages, added rear doors or newer slab doors that never received the same hardware as the original front entry. Many of those homes still carry mid-century Kwikset or Weiser sets and aging tubular deadbolts, so new installations are often paired with matching upgrades at the main door.

Along Pioneer Blvd, Firestone Blvd and Rosecrans Ave, the 1960s and 70s stucco dingbat apartment buildings bring a different set of needs. Aluminum sliding patio doors on original mortise latches often get an added secondary lock, and landlords add deadbolts to storage rooms, laundry rooms or gates. In the Norwalk Civic Center and Town Square district, small shops sometimes need a lock added to a back office, stockroom or new rear entrance.

We work throughout Norwalk, including ZIP codes 90650, 90651 and 90652, and the areas around I-5, I-605, Cerritos College and the Norwalk Metro C Line and Metrolink stations. Whatever the door, call (323) 997-8867 any hour and we will come to you.

Lock Installation in Norwalk — FAQs

What does lock installation cover in Norwalk?
It covers putting a new lock on a door or opening that did not have one, such as a converted garage, a new side entry, a back house or a gate. It differs from replacing or rekeying an existing lock. Call (323) 997-8867 to describe your door.
Can you install a lock on a hollow-core or older door?
Often yes, but it depends on the condition of the door. Hollow-core doors are weak for a deadbolt, so we may recommend a more solid door or added reinforcement. We assess it on site and tell you what will actually work.
Can you add a lock to an aluminum sliding patio door?
Yes. Many older Norwalk apartments and homes have sliders on original latches. We can add a secondary lock suited to the frame. The right option depends on the slider's track and frame, which we check when we arrive.
Do you install locks outside regular business hours?
Yes. We are available 24/7 and fully mobile. If a new door was just hung or a break-in left an opening unsecured, call (323) 997-8867 at any hour.
Can several new locks use the same key?
Yes, we can key locks alike so one key works multiple doors. This is handy for homeowners with a front door, side door and garage entry, and for landlords managing several doors.
Do you install electronic or keypad locks?
We can install keypad and smart lock options where the door and your needs suit them. We go over the pros and cons, including battery upkeep and a mechanical backup, before installing anything.
Can you install locks for a small business near Norwalk Town Square?
Yes. We install locks on back offices, stockrooms and rear entrances for small commercial spaces, including after hours so your business is not disrupted. Call (323) 997-8867 to arrange it.
Will I need to bring the door to a shop?
No. We are fully mobile and have no storefront. We do the work at your door in Norwalk, using the tools and hardware we carry.
