Lock installation is different from simple repair. You are putting new hardware into a door that may never have had a proper lock, or replacing something so worn it can no longer protect the property. In Westmont, that comes up often: a front door on a 1940s stucco bungalow with an original knob and nothing else, a side door added during a remodel, or a back gate that has only ever been held shut with a chain.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar and the team are fully mobile. There is no storefront to visit. We bring the tools and hardware to your door, any hour of the day or night, and do the work on site.

A good installation is more than a lock that turns. The door has to be bored accurately, the latch and bolt have to line up with the strike, and the strike has to be anchored into the frame rather than just the thin trim. On older Westmont homes, where wood has dried, shifted, and been painted many times over the decades, those details decide whether a new lock actually adds security or only looks like it does.

How it works in Westmont

  1. 1

    Tell us about the door and the goal

    When you call (323) 997-8867, we ask what the door is, what material it is made of, and what you want from the lock. Is it a new entry, a back door, a bedroom, a duplex unit, or a business door? That helps us bring the right hardware.

  2. 2

    Inspect the door and frame on site

    We check the door thickness, the condition of the wood or metal, and how solid the frame is. Older bungalow doors are often thin or warped, and frames may be soft or cracked, which affects what can be installed and how.

  3. 3

    Choose the hardware with you

    We explain the options, such as a deadbolt, a knob or lever set, a keyed-alike set so one key works at multiple doors, or a higher-security cylinder. You decide what fits your needs and comfort level.

  4. 4

    Prepare the door and install

    We drill or fit the door for the new lock, mount the latch and bolt, and install the strike plate. Where the frame is weak, we recommend a reinforced strike with longer screws that bite into the stud behind the trim.

  5. 5

    Test and hand over keys

    We operate the lock repeatedly with the door open and closed, confirm the bolt throws fully, and check that the door closes without binding. Then we hand over your keys and show you how everything works.

What affects the price

  • The type of lock: a basic knob set, a standard deadbolt, a high-security cylinder, and a commercial-grade lock all differ in hardware cost.
  • Door condition and material: a solid wood, hollow-core, metal, or security door each need different preparation, and a door that was never drilled takes more work.
  • Frame and strike reinforcement: a cracked or soft frame may need repair or a reinforced strike plate and longer screws.
  • The number of locks: several doors on one visit, or keyed-alike sets across a duplex or apartment building, change the total scope of work.
  • Specialty hardware: gate locks, roll-down security gate locks, or commercial storefront hardware involve different parts and more time than a standard residential door.
  • Time of service: because we are available 24/7, a late-night or emergency visit may be priced differently from a scheduled daytime appointment.

Why Westmont chooses us

  • We are fully mobile, so installation happens at your door with the hardware in our vehicle. You are not sent to a shop or asked to pick up parts.
  • Serving Greater Los Angeles since 1987 means David Shar and the team have seen decades of older door and frame conditions, including the worn wood common to prewar housing.
  • We look at the frame, not just the lock. A strong deadbolt in a weak frame is only partly effective, so we tell you honestly when reinforcement is worthwhile.
  • We handle both residential and commercial work, from a bungalow front door to a market or mini-mall unit with a roll-down gate.
  • We are available 24/7, so a door that cannot be secured tonight does not have to wait until morning.
  • We explain options plainly and let you decide, without pushing hardware you do not need.

Lock Installation across Westmont

Westmont sits in unincorporated Los Angeles County, and its housing is a good reason to think carefully about lock installation. Many blocks off the Western Avenue corridor and the Vermont Avenue corridor are lined with small stucco homes and California bungalows from the 1920s through the 1950s, along with duplexes and small apartment buildings. Doors on these properties are often original, and the hardware has usually been replaced piecemeal, if at all. We frequently install a proper deadbolt, and a reinforced strike plate, where an older home only ever had a knob lock. Homes near 90047 and 90044 share much of this character.

The commercial side of Westmont matters too. Western Avenue, Vermont Avenue, and the Imperial Highway commercial strip are full of markets, auto shops, and mini-mall units, many with roll-down security gates. These need locks suited to heavier use and to metal doors and gates, which differs from a bungalow door. We can install gate locks and storefront hardware for business owners along these corridors, including the Vermont and Manchester area.

We also work in nearby neighborhoods such as Vermont Knolls and West Athens, and for people who live close to Jesse Owens Community Regional Park or Washington Preparatory High School. Wherever the door is, we come to you, since we have no storefront. Call (323) 997-8867 any time to discuss what you need.

Lock Installation in Westmont — FAQs

Can you install a deadbolt on a door that only has a knob lock?
Yes. If the door is thick enough and in good condition, we can add a deadbolt above the existing knob. We inspect the door first to confirm it can take the additional hole safely. Call (323) 997-8867 to describe your door.
Is my older bungalow door suitable for a new lock?
Often it is, though older wood doors and frames can be dry, warped, or cracked. We check the condition on site and tell you if the frame needs repair or reinforcement before the new lock will perform well.
What is a reinforced strike plate and do I need one?
It is a heavier strike plate fastened with longer screws that reach the wall stud behind the trim. It helps the door resist being forced or kicked in. We often recommend it for older homes and after a break-in.
Can you install locks on a rental duplex or apartment unit?
Yes. We install new locks for landlords and property managers, including keyed-alike sets when several doors should share a key. We can also rekey existing locks after tenant turnover if replacement is not needed.
Do you work on roll-down security gates and storefront locks?
Yes. We install and service gate locks and commercial door hardware for businesses, including units along Western Avenue, Vermont Avenue, and Imperial Highway. Call (323) 997-8867 to describe the gate or door.
Do I need to visit your shop to choose a lock?
No. We are fully mobile and have no storefront. We bring hardware options to your door and help you choose there.
Are you available outside normal business hours?
Yes, we operate 24/7. If a door cannot be secured, for example after a break-in or a damaged lock, you can call us at any hour.
How is the price of lock installation determined?
It depends on the lock type, the door material and condition, any frame reinforcement, how many locks are involved, and whether the work is scheduled or urgent. We discuss the scope with you before starting.
