A deadbolt is often the single most useful upgrade you can make to an entry door. In Chatsworth, the doors that need one vary a great deal. There are 1950s to 1970s ranch homes whose original hardware has worn out, hillside houses that deal with dust and heat, horse properties with barns and tack rooms, and warehouses along the industrial corridor. Each of these calls for a different lock and a different installation approach.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile. There is no shop to visit, because we bring the hardware to your property and do the work on site, at any hour.

Whether you want a first deadbolt on a door that has only a spring latch, a replacement for one that has seized, or a keyed-alike setup so one key covers several doors, we start by looking at the door itself. Door thickness, the condition of the edge and frame, and how the door is used all affect which deadbolt will hold up and how it should be fitted.

How it works in Chatsworth

  1. 1

    Talk through the door and the goal

    When you call (323) 997-8867, we ask what the door is, whether it is a front door, a garage side door, a barn door or a commercial entry, and what you want from the lock. That tells us whether you need a single-cylinder, a double-cylinder, or a heavier commercial-grade bolt.

  2. 2

    Inspect the door and frame on site

    We check the door's thickness, the existing bore holes, and the condition of the edge and jamb. Older ranch-home doors often have worn or oversized holes, and a weak frame can undermine even a good deadbolt, so we point out anything that needs reinforcing.

  3. 3

    Choose the right hardware

    We go over the options with you, including single- or double-cylinder, keyed-alike sets, and residential versus commercial-grade bolts. We explain trade-offs plainly. A double-cylinder can be useful on a door with glass nearby but needs thought for emergency exit.

  4. 4

    Install and align

    We bore or adapt the door as needed, set the bolt and strike, and make sure the bolt throws fully into the frame without binding. Where the frame is weak, we fit a reinforced strike plate with appropriate screws.

  5. 5

    Test, key and hand over

    We cycle the lock several times with the door open and closed, confirm every key works, and show you how it operates. For multiple doors, we can key them alike so you carry fewer keys.

What affects the price

  • Whether this is a new installation on an uncut door or a replacement in an existing bore, since new holes mean more work.
  • The grade and type of deadbolt, from standard residential models to high-security or commercial-grade hardware.
  • Single- versus double-cylinder, and whether you want several locks keyed alike or to a master key.
  • Door material and condition, including solid wood, metal, or aging doors that need repair before the lock will sit properly.
  • Frame and strike reinforcement, which matters on older homes where the jamb has weakened over time.
  • The number of doors or gates on the job, and whether the work is at a home, a barn or a warehouse.

Why Chatsworth chooses us

  • We are fully mobile and available 24/7, so a deadbolt can be installed the same day you notice the problem, without a trip to a shop.
  • Serving Greater Los Angeles and Ventura County since 1987, we have seen the full range of doors found in the northwest Valley, from tract-home entries to farm gates.
  • We handle residential, equestrian and commercial work, so one call can cover your house, your barn and a business door.
  • We tell you honestly when a frame or door needs repair first, rather than fitting a new lock into a weak setup.
  • We can key multiple locks alike, which suits property owners with several doors, outbuildings or tenants.
  • The owner, David Shar, leads the work, so there is clear accountability for how the job is done.

Deadbolt Installation across Chatsworth

Chatsworth sits in the northwest corner of the San Fernando Valley against the Santa Susana Mountains, and the housing reflects that. Many homes in ZIP 91311 are 1950s to 1970s ranch houses, where the original entry hardware is often decades old. Near Stoney Point Park and the Indian Hills and Santa Susana Pass area, hillside homes face heat, dust and Santa Ana grit that can seize an exterior deadbolt. In that case we clean, re-pin or replace it, depending on what is actually wrong.

The equestrian horsekeeping district has its own needs. Properties with barns, tack rooms and gated driveways often need sturdy deadbolts on outbuilding doors, and we can also help with padlocks and gate locks on the same visit. If you are near Santa Susana Pass Road and locked out of a tack room, the same call can sort out the lock and a replacement.

Along Lassen, Prairie and Canoga in the industrial and business district, in ZIP 91311 and nearby 91313, tenants often need commercial-grade deadbolts, especially after a lease change when locks should be rekeyed to a single master. We work around Topanga Canyon Blvd, Devonshire St, Nordhoff St and the Ronald Reagan Fwy, coming to you at home, at the barn or at the warehouse.

Deadbolt Installation in Chatsworth — FAQs

Can you install a deadbolt on a door that does not have one?
Yes. We can add a deadbolt to a door that only has a spring latch, provided the door is thick and solid enough. We check the door first, then bore and fit the lock. Call (323) 997-8867 to describe your door.
Should I choose a single- or double-cylinder deadbolt?
A single-cylinder turns with a key outside and a thumb-turn inside, which suits most doors. A double-cylinder needs a key on both sides and is sometimes used near glass, but it can slow exit in an emergency. We will talk through which fits your door.
My deadbolt is stuck from dust and heat. Do I need a new one?
Not always. Hillside homes near Stoney Point can get grit and heat damage in the lock. We can often clean or re-pin it, and we replace it if it is worn out. We tell you which makes sense.
Can you install deadbolts on barn or tack-room doors?
Yes. We work on equestrian properties around Chatsworth and can fit deadbolts on outbuilding doors, and also help with padlocks and driveway gate locks. Call (323) 997-8867 to talk through the setup.
Can you key several deadbolts to the same key?
Yes. We can key multiple locks alike so one key works on your front door, side door and outbuildings. For businesses, we can also set up a master key arrangement.
Do you handle commercial deadbolts for warehouses?
Yes. We install high-security commercial deadbolts and can rekey existing locks to a single master after a lease change. We also handle roll-up-door padlocks and related hardware.
Do I need to come to a shop?
No. We are fully mobile with no storefront. We come to your home, barn or business in Chatsworth, and we are available 24/7.
Will a new deadbolt help if my door frame is weak?
A deadbolt is only as strong as the door and frame around it. We inspect the jamb and can fit a reinforced strike plate with longer screws where needed, so the new lock does its job.
