Installing a lock sounds simple until the door, the frame, and the hardware all have to agree. In Northridge, that means a wide range of situations: a freshly built door in a remodeled ranch home, a new gate on a horse property, a deadbolt added to a side door that never had one, or a set of units near the university that need proper hardware before tenants arrive. Each one calls for a different lock and a slightly different approach.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business around doing the work properly at the customer's location. We are a mobile-only service. There is no storefront to visit; we bring the tools, the hardware, and the know-how to your door, at any hour, any day of the week.

Lock installation is different from replacing a lock that already works. When there is no existing hole, we have to work out where the lock should sit, how the door is built, and whether the frame can carry a deadbolt's throw without flexing. Northridge adds its own wrinkle, because many homes here have lived through decades of settling since the 1994 earthquake. We check how a door actually closes before we cut anything, so the new lock works smoothly on day one and keeps working.

How it works in Northridge

  1. 1

    Talk through the door and the goal

    When you call (323) 997-8867, we ask what you are securing, what kind of door or gate it is, and who needs keys. A bedroom office, a rental unit, a tack room, and a front entry each want a different solution, so a few questions up front save a second trip.

  2. 2

    Inspect the door, frame, and alignment

    On arrival we look at the door material, thickness, and edge, and check how it meets the frame. Older Northridge tract homes can have frames that have shifted over the years, so we test the closing action before drilling anything.

  3. 3

    Select hardware that fits the use

    We recommend a lock that suits the door and the situation, whether that is a deadbolt, handleset, keyed-alike set, or a heavy-duty gate or outbuilding lock. We explain the options plainly, including what we would not recommend for the application.

  4. 4

    Prepare the door and install

    We mark, bore, and fit the lock and strike with care for clean edges and correct backset. Where a door has no prior hardware, we make sure the strike is anchored into solid framing rather than just trim.

  5. 5

    Test, key, and walk you through it

    We operate the lock repeatedly with the door open and closed, confirm every key works, and set up keyed-alike arrangements if you asked for them. Before we leave, we show you how everything operates.

What affects the price

  • The type of lock chosen, from a basic deadbolt to a high-security cylinder or a weather-rated gate lock.
  • The door material and condition, since solid wood, metal, and hollow-core doors need different prep.
  • Whether the door needs fresh boring or the frame needs reinforcement or realignment before the lock will seat properly.
  • The number of locks, and whether they should be keyed alike so one key opens everything.
  • The location and time of the visit, including after-hours or weekend service, since we are available around the clock.
  • Whether specialty fittings are needed, such as strike plates for settled frames or hardware for outdoor use.

Why Northridge chooses us

  • Fully mobile service since 1987, so the work is done at your door and there is no shop to drive to.
  • Available 24/7, including nights and weekends, when a new door or an unsecured entry cannot wait.
  • Owner-led by David Shar, with experience across older tract homes, apartments, and rural-style properties.
  • We check door and frame alignment first, which matters in Northridge homes where settling can bind a deadbolt.
  • Comfortable with keyed-alike setups for multi-door properties such as rentals and horse properties.
  • We explain the options and tell you honestly when a simpler or sturdier choice fits better.

Lock Installation across Northridge

Northridge covers a lot of different living situations, and lock installation here reflects that. Around the CSUN and university district, student-rental apartments and small complexes along Reseda Blvd, Nordhoff St, and Zelzah Ave often need new or additional locks as units are renovated or converted, especially ahead of the fall semester. Landlords commonly want matching hardware across several doors, and we can install and key them to a consistent plan.

In the Devonshire residential area and the quieter streets near Northridge Village, many homes are 1950s and 1960s ranch-style tract houses. These often have original doors, side entries, and garage service doors that never got a proper deadbolt. Since the 1994 earthquake, which was centered in neighboring Reseda, some frames in the area have shifted slightly, so we always test alignment before installing. A lock that fits a true frame can bind badly in a settled one, and the strike location is where we make the difference. Addresses in ZIP codes 91324, 91325, 91326-adjacent streets, and 91330 around campus all see this mix.

Sherwood Forest is a different story, with its horsekeeping estates. Barns, tack rooms, and driveway gates need rugged, weather-tolerant hardware, and owners usually prefer a single key for everything. We install and key those locks alike so a property is simple to manage. Whether you are near Northridge Fashion Center, off Tampa Ave in 91325, or out toward Balboa Blvd in 91328, we come to you, and you can reach us any time at (323) 997-8867.

Lock Installation in Northridge — FAQs

What does lock installation include?
We assess the door and frame, recommend suitable hardware, prepare the door, install the lock and strike, and test everything with your keys. Call (323) 997-8867 and we will explain what fits your situation.
Is installing a new lock different from replacing one?
Yes. Replacement uses an existing hole and fit, while installation often means boring a new door or adding a lock where none existed. That takes more measuring and care to keep the door strong.
My front deadbolt has been sticking since the house settled. Can you fix it?
Often, yes. Older Northridge homes can have frames that shifted over the years. We can realign the strike, adjust the fit, or install new hardware. Call (323) 997-8867 to describe what is happening.
Can you install locks on a barn, tack room, or gate?
Yes. We install weather-tolerant locks for outbuildings and gates, and we can key them all alike so one key covers the whole property, which is handy for Sherwood Forest horse properties.
Can you do several doors keyed alike for a rental?
Yes. We can install matching hardware across multiple doors and set them up to work with one key or a clear key plan. This suits landlords near CSUN preparing units for new tenants.
Do you offer lock installation at night or on weekends?
We are available 24/7 and fully mobile. If you need a door secured after hours, call (323) 997-8867.
Do I need to be present for the installation?
Someone should be there to confirm what is being installed and receive the keys. For rentals and managed properties, we can coordinate with a property manager.
Do you have a shop I can visit to pick out a lock?
No. We are mobile only. We bring suitable hardware to your door and go through the options with you on site.
