A deadbolt is one of the simplest upgrades you can make to a home or small business, and also one of the easiest to get wrong. A bolt that doesn't throw deeply into a solid strike, a strike plate held by short screws, or a cylinder that is cheap and easy to bypass can leave a door only marginally better than the latch alone. In Hacienda Heights, where so many homes were built in the 1960s and 1970s, we often find original hardware that has worn out, been painted over, or never had a real deadbolt in the first place.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar and our technicians bring that experience to every install. We are fully mobile, so there is no shop to visit. We come to your door with a range of deadbolts, strikes, and boring tools, check how your door is actually built, and fit the hardware so it operates smoothly and holds up.

We do first-time installs on doors that have only a knob lock, replacements for deadbolts that stick or have been compromised, and upgrades to higher-security or electronic models. We can also key the new deadbolt to match your existing locks, so you aren't carrying an extra key for every door.

How it works in Hacienda Heights

  1. 1

    Tell us about the door

    When you call (323) 997-8867, we ask what the door is made of, whether it already has a bore hole, and whether this is a new install or a replacement. We also ask whether you want one key for several doors, a keypad, or a standard keyed model.

  2. 2

    Inspect the door and frame

    On arrival we look at the door's thickness, edge, and condition, and at the jamb the bolt will enter. A strong bolt in a split or soft frame accomplishes little, so we point out anything that should be reinforced before we install.

  3. 3

    Choose the right deadbolt

    We go over single-cylinder models, which use a thumbturn inside, and double-cylinder models, which need a key on both sides. We explain the tradeoffs honestly, including how double-cylinder locks can affect exit in an emergency, and let you decide.

  4. 4

    Install and reinforce

    We drill or reuse the existing bore, set the bolt, and fit a strike plate secured with long screws that reach the framing behind the jamb. Where needed we add a reinforcement plate so the door resists being forced.

  5. 5

    Test and key to your needs

    We operate the lock repeatedly with the door open and closed, confirm the bolt extends fully, and check alignment. If you asked for keyed-alike hardware, we confirm that your keys work across the doors we matched.

  6. 6

    Walk-through and care tips

    Before we leave, we show you how to use any smart features, how to reset codes if applicable, and what to watch for as the door and frame shift with seasons. You leave with working hardware and clear next steps.

What affects the price

  • Whether the door already has a bore hole for a deadbolt or we need to cut a new one, which changes the labor involved.
  • The grade and type of deadbolt you choose, from standard keyed models to higher-security or electronic and smart versions.
  • Door material and condition, since solid wood, metal, and older hollow or damaged doors need different handling.
  • Frame and strike reinforcement, such as longer screws or a reinforcement plate, when the jamb is weak or worn.
  • How many doors are being done and whether you want them keyed alike, which affects both materials and time.
  • Whether the visit is during regular hours or an after-hours or emergency call, given that we operate 24/7 as a mobile service.

Why Hacienda Heights chooses us

  • Fully mobile service: we work on your door at your property, so there is no need to remove it or bring it anywhere.
  • Serving the region since 1987, with owner and lead technician David Shar guiding the standards we follow on installs.
  • We check the door and frame first and tell you plainly if reinforcement is needed, rather than just swapping the lock.
  • We install standard, double-cylinder, and electronic deadbolts, and explain the pros and cons so you pick what suits your household.
  • We can handle related hardware on the same visit, such as gate hardware or a patio slider latch, so you aren't juggling multiple providers.
  • Available 24/7, which matters when a door is left insecure after a break-in attempt or a failed lock.

Deadbolt Installation across Hacienda Heights

Hacienda Heights has a distinctive mix of housing, and the right deadbolt often depends on where you live. In the flats, including the Stimson-area streets and much of The Heights, many 1960s and 1970s tract homes still have original knob-and-latch hardware or tired, undersized deadbolts. Adding a properly fitted deadbolt with a solid strike is one of the most practical improvements for homes in ZIP code 91745. Attached garages are common here, so the interior door from the garage to the house deserves the same attention as the front door.

Up on the Skyline hillside tracts and the Puente Hills slopes, homes tend to be larger custom or view properties with higher-grade entry hardware and sometimes gated driveways. These often call for matching finishes, upgraded deadbolts, or smart models, and a call from a hillside home may involve both the main entry and gate hardware. Access off Hacienda Blvd, Colima Rd, and Azusa Ave, plus quick reach from SR-60, lets us serve homes from the flats to the hills.

We also work with businesses and institutions in the area, from strip centers along the Colima Road commercial corridor to organizations near Hsi Lai Temple. After staff turnover, a deadbolt swap or rekey can restore control over who has access. Whether you live near Schabarum Regional Park or Steinmetz Park, or work along Colima, call (323) 997-8867 any time.

Deadbolt Installation in Hacienda Heights — FAQs

Can you install a deadbolt on a door that only has a knob lock?
Yes. If the door is thick enough and sound, we can drill the bore for a deadbolt and install a strike in the frame. Call (323) 997-8867 and we'll ask about your door first.
What's the difference between single- and double-cylinder deadbolts?
A single-cylinder deadbolt uses a key outside and a thumbturn inside. A double-cylinder needs a key on both sides, which can help when glass is near the lock but makes quick exit harder in an emergency. We explain both before you decide.
Do you install smart or keypad deadbolts in Hacienda Heights?
Yes. Electronic and smart deadbolts are increasingly common in the area, and we can install and test them, then show you how to manage codes. Call (323) 997-8867 to discuss models.
Will a new deadbolt help if my door frame is old or weak?
Only partly. A strong bolt needs a solid jamb behind it. We inspect the frame and can add a longer-screw strike or a reinforcement plate so the whole setup holds up.
Can you key several deadbolts to the same key?
Yes, we can set up keyed-alike hardware for front, back, and garage doors so you carry fewer keys. Tell us how many doors when you call.
Do you handle patio sliders as well as front doors?
Yes. Many 1970s tract homes here have sliders with multi-point or loop-lock hardware that can fail. We can repair or secure them as part of the visit, even in an emergency.
Do I need to come to a shop?
No. Crenshaw Lock is fully mobile with no storefront. We come to your home or business in Hacienda Heights and work on site.
Can you install a deadbolt after hours?
Yes, we operate 24/7. If a door is insecure at night, call (323) 997-8867 and we'll work out how to get it secured.
