Lock installation is different from a repair or a lockout. You are putting hardware where none existed, or replacing it on purpose with something better. In Simi Valley that comes up in a few familiar ways: a new entry door on a 1970s ranch home, a side gate or garage service door that never had a deadbolt, a remodel that changed the door layout, or a switch to keyed-alike and smart hardware across a whole house.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on a simple idea: show up with the right tools, explain the options plainly, and install the hardware correctly the first time. We are fully mobile. There is no storefront to visit, so everything happens at your property, with the door in front of us.

A good installation is mostly about fit. Door thickness, bore size, backset, strike alignment, and the frame behind the strike plate all decide whether a lock works smoothly and actually resists force. A deadbolt in a hollow, worn frame is only as strong as the wood around it. We look at the whole door, not just the lock body, and tell you what makes sense for your situation.

How it works in Simi Valley

  1. 1

    Talk through the door and the goal

    Call (323) 997-8867 and tell us what you are securing: a new front door, a garage side door, a back slider, or a whole-house upgrade. We ask about door material, existing holes, and whether you want keyed, keypad, or smart operation, so the right hardware comes with us.

  2. 2

    Inspect the door and frame on site

    We check door thickness, existing bore holes, backset, and the condition of the jamb. Older tract homes often have dried, split, or loosened frames around the strike. If the frame is the weak point, we explain what can be reinforced during the install.

  3. 3

    Choose hardware that fits the use

    We go over grade levels, finishes, and key systems with you. A busy family entry, a rental that turns over tenants, and an HOA-regulated gated home each call for different choices. You decide; we explain the tradeoffs honestly.

  4. 4

    Prepare and install cleanly

    If a new bore or latch hole is needed, we cut it with proper tools so the door face stays tidy. We set the deadbolt and latch, fit the strike plate, and use long screws into the framing where appropriate rather than short screws into thin trim.

  5. 5

    Test, key, and hand over

    We cycle the lock repeatedly with the door open and closed, confirm the bolt fully throws, and check that keys or codes work. We can key new locks alike so one key runs the house, and we walk you through programming on any electronic hardware.

What affects the price

  • The type of lock: a basic keyed deadbolt, a high-security cylinder, a keypad, and a smart lock all differ in hardware cost and setup time.
  • Whether the door is already drilled for the lock or needs new bore holes cut, which adds labor, especially on solid wood or metal doors.
  • The number of locks and whether they should be keyed alike, which affects both materials and time on site.
  • Door and frame condition, including any reinforcement of a worn or split jamb or strike area.
  • Finish and brand requirements, such as matching HOA-standardized hardware in a planned community.
  • Time and location of the visit, since we serve Ventura County around the clock and after-hours work is scheduled differently from daytime appointments.

Why Simi Valley chooses us

  • Fully mobile service: we bring the tools and a range of hardware to your Simi Valley door, so you are not driving to a shop.
  • Since 1987 in Greater Los Angeles and Ventura County, with the owner, David Shar, leading the work.
  • We look at the door and frame as a system, not just the lock, because installation quality depends on both.
  • Familiarity with local housing, from 1970s tract homes with worn Kwikset and Schlage hardware to newer HOA-managed developments with smart locks.
  • Plain explanations of options and grades, with no pressure to buy more than the door needs.
  • Available 24/7, so you can arrange an installation when the schedule suits you or when a break-in leaves a door needing new hardware right away.

Lock Installation across Simi Valley

Simi Valley has a wide mix of housing, and lock installation looks different from one neighborhood to the next. In Texas Tract and much of the area around ZIP 93065, many homes are 1960s to 1990s single-family tract builds. Original or worn hardware is common, and adding a quality deadbolt or swapping aging Kwikset sets for sturdier ones is a frequent project. Landlords there also ask for new hardware between tenants.

In Wood Ranch and Big Sky, in ZIP 93065 and nearby 93063, homes are newer, often in gated or semi-gated communities with HOA-standardized hardware. Installations here usually mean matching an approved finish, adding a smart lock, or retrofitting a side door or casita entrance without disturbing the look of the door. In Santa Susana Knolls, the older rustic homes on winding lanes sometimes have unusual door sizes, thick old wood, or no deadbolt at all, so we measure carefully and adapt hardware to the door.

We serve every part of the city, from the Bridle Path area to homes near the Ronald Reagan Presidential Library and Simi Valley Town Center, and across ZIPs 93062, 93063, 93064, 93065, and 93094. Whether you are just off Madera Rd, Tapo Canyon Rd, or Sycamore Dr, or near SR-118 or SR-23, call (323) 997-8867 and we will come to you.

Lock Installation in Simi Valley — FAQs

Can you install a deadbolt on a door that does not have one?
Yes. If the door is thick enough and sound, we can cut the bore and latch holes and fit a deadbolt, then reinforce the strike area. Call (323) 997-8867 and describe the door so we can bring the right hardware.
Do you install smart locks in Simi Valley homes?
Yes. We install and set up keypad and smart locks, including in HOA communities like Wood Ranch and Big Sky where finish and hardware standards matter. We confirm compatibility with your door and walk you through programming before we leave.
How do I choose between a standard deadbolt and a higher-grade lock?
It depends on the door's use and risk. A busy main entry or a rental often benefits from a stronger grade and a reinforced strike. We explain the differences in plain terms and let you decide.
Can all my exterior doors use one key?
Usually, yes. We can install new locks keyed alike so a single key works the front door, back door, and garage entry, as long as the chosen hardware supports it.
Do you install locks on new construction or remodeled doors?
Yes. New doors, relocated doors, and remodeled entries all need correctly bored and aligned hardware. We install to the door manufacturer's specifications and test everything before finishing.
Is installation different from rekeying or replacing a lock?
Yes. Installation means adding hardware where none existed or fitting a new type. Rekeying changes the internal pins of an existing lock. If you are not sure which you need, call (323) 997-8867 and we will help sort it out.
Do you offer lock installation outside normal business hours?
We are available 24/7 and fully mobile across Simi Valley and Ventura County. Planned installations are easiest to schedule ahead, and urgent needs like securing a door after a break-in can be arranged any time.
Will installing a new lock damage my door's finish?
We work carefully to protect the finish, and on existing bores we often match them exactly. If new holes are required, we cut them cleanly and tell you in advance what to expect.
