A deadbolt is the single most useful upgrade you can make to an entry door, and in Winnetka there is a lot of room for improvement. Much of the neighborhood is made up of 1950s and 60s tract homes and mid-century and 1970s-80s apartment buildings, and many of those doors still carry builder-grade hardware: a spring latch in the knob, maybe an old deadbolt that sticks, or no deadbolt at all. Adding a properly installed deadbolt gives the door a real throw of steel into the frame instead of relying on a latch that a flat tool can slip.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on mobile service. We come to you, whether that is a single-family house near Winnetka Ave and Sherman Way, a condo unit, or a ground-floor apartment along Vanowen St. We are available around the clock, so a door that will not secure at night does not have to wait for morning.

Installation is more than screwing a lock into a hole. The door has to be bored correctly, the strike has to line up, and the screws that hold the strike need to reach the framing behind the jamb. We pay attention to these details because a deadbolt is only as strong as the door and frame it sits in. We can also match the new deadbolt's keyway to your existing lock so one key works, or key it separately if you prefer.

How it works in Winnetka

  1. 1

    Tell us about the door

    Call (323) 997-8867 and describe the door: wood, metal or solid core, whether it already has a deadbolt, and whether you want single or double cylinder. Photos of the edge and jamb help us bring the right hardware.

  2. 2

    Check the door and frame

    On arrival we inspect the door thickness, existing bore holes, jamb condition and strike area. Tract-home doors and older apartment doors often have worn or split wood that needs attention before a new bolt will perform.

  3. 3

    Choose the right cylinder style

    We explain the difference between single-cylinder (thumbturn inside) and double-cylinder (key on both sides). We talk through convenience and emergency exit, especially for apartments and homes with glass near the door.

  4. 4

    Install and align

    We bore or adapt the holes as needed, set the latch, mount the deadbolt, and install the strike with long screws that reach the framing. The bolt should extend and retract smoothly without forcing the door.

  5. 5

    Key it the way you want

    We can key the deadbolt to match your existing lock or to a new key. For condos and managed buildings, we can discuss matching key requirements where the building allows it.

  6. 6

    Test and hand over keys

    We cycle the lock several times with the door open and closed, confirm the door closes cleanly, and hand over your keys. You get a short walkthrough on how to keep the lock working well.

What affects the price

  • Whether you are adding a brand-new deadbolt to a door with no bore or replacing an existing one that already fits
  • Single-cylinder versus double-cylinder hardware, and the grade and finish of the deadbolt you choose
  • Door material and condition, since solid wood, hollow-core and metal doors each need different handling and a damaged door or jamb may need repair
  • Number of doors or units, which matters for property managers handling several apartments in one visit
  • Whether you want keys matched to an existing lock, a shared key, or a fresh keying
  • Time of day, since after-hours and emergency visits differ from scheduled daytime appointments

Why Winnetka chooses us

  • Fully mobile service, so the work happens at your door rather than through a shop visit, and there is no storefront to drive to
  • In business since 1987, with owner David Shar leading the work rather than handing it off to a call center
  • We look at the frame and strike, not just the lock, because most weak deadbolts fail at the jamb
  • Familiar with Winnetka's mix of tract homes, mid-century apartments and condos, and the hardware typically found in each
  • Available 24/7, which helps when a broken lock leaves your door unsecured overnight
  • Clear explanation of single versus double cylinder so you choose for your situation, not ours

Deadbolt Installation across Winnetka

Winnetka is a central-west San Fernando Valley community where the housing tells you what to expect behind the door. Around the Winnetka Ave and Sherman Way residential core, many 1950s and 60s tract homes still have their original front-door hardware, often a basic knob lock with a thin deadbolt or none at all. Homeowners near Prairie Street Elementary and the Winnetka Recreation Center often call us when an original lockset finally starts to fail and they decide to add a proper deadbolt at the same time.

Along the Vanowen St multifamily corridor and the De Soto Ave apartment district, the picture changes. Mid-century and 1970s-80s complexes see steady tenant turnover, so property managers need deadbolts added, replaced or rekeyed across several units. Condo owners have their own wrinkle: a unit deadbolt may need to work with building rules or common-entry keys. We handle these jobs on site, whether the building sits near Winnetka Bowl on Vanowen or a few blocks off Saticoy St or Roscoe Blvd.

We serve all of 91306, from Victory Blvd to Mason Ave, and reach the area easily from US-101 and the Northridge Fashion Center side to the north. Call (323) 997-8867 any hour and we will plan the visit around your door.

Deadbolt Installation in Winnetka — FAQs

Can you add a deadbolt to a door that only has a knob lock?
Usually yes. If the door is thick enough and in good condition, we can bore a new hole above the knob and install the deadbolt. Call (323) 997-8867 and describe the door so we can bring the right hardware.
Should I choose a single- or double-cylinder deadbolt?
Single-cylinder locks have a thumbturn inside, which makes exiting quick in an emergency. Double-cylinder locks need a key on both sides and are mainly considered when there is glass near the door. We will talk through the tradeoffs for your entry.
Can you match the new deadbolt to my existing key?
In most cases we can key the new deadbolt to match your current lock so you carry one key. If you would rather have a separate key, we can do that too.
I manage apartments off Vanowen. Can you handle several units?
Yes. We work with property managers who need deadbolts installed or replaced across multiple units, often alongside rekeying after move-outs. Call (323) 997-8867 to talk through the number of doors and scheduling.
Is a new deadbolt enough if my door frame is weak?
Not always. A strong bolt in a split or loose jamb can still fail. We check the frame and strike area and install the strike with long screws into the framing, and we will tell you if the door or jamb needs repair.
Do you offer installation at night or on weekends?
Yes, we are available 24/7 and fully mobile. If your door will not lock securely, you can call (323) 997-8867 at any hour.
I live in a condo. Will a new deadbolt work with the building's keys?
It depends on the building's rules. Some condos and HOAs require unit locks to stay on a certain key system. Tell us about your building when you call and we will work within what is allowed.
Do I need to come to a shop to pick out a deadbolt?
No. Crenshaw Lock Company is mobile only, with no storefront. We bring hardware options to your door in Winnetka and install on the spot.
