Most of the locks in Lawndale were never chosen with security in mind. In a small city of roughly two square miles, built out mostly in the 1950s through the 1980s, a great deal of the hardware is builder-grade: knobs and deadbolts that were installed once, passed between tenants and owners, and never upgraded. These locks can often be picked, bumped or forced by someone with modest tools and very little time. A high security lock is designed to close those specific gaps.

High security hardware differs from a standard lock in several ways. Tighter tolerances and special pin designs resist picking and bumping. Hardened inserts protect against drilling. Many systems also use restricted keyways, meaning keys cannot be copied at a hardware-store kiosk without authorization. That last point matters a lot in a rental-dense city, where keys tend to wander over the years.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are mobile only, with no storefront to visit. We assess the door where it stands, recommend hardware that fits the door and the way you use it, and install it on site. We would rather tell you that a good deadbolt and a proper strike plate are enough than sell you something you do not need.

How it works in Lawndale

  1. 1

    Tell us about the door and the concern

    Call (323) 997-8867 and describe what you are protecting: a stucco single-family front door, an apartment unit, a barred security door, or a retail entry. Tell us if you have had a break-in, lost keys, or a tenant turnover, since that shapes the recommendation.

  2. 2

    On-site assessment

    A technician comes to you and inspects the door, frame, strike plate, hinges and existing hardware. On older Lawndale homes the weak point is often the frame or a short strike screw, not only the lock, and we point that out honestly.

  3. 3

    Choose the right level of protection

    We explain the options: pick- and bump-resistant cylinders, drill-resistant hardened components, and restricted key systems with controlled duplication. For landlords we also discuss keying multiple units with a master or keyed-alike arrangement for maintenance access.

  4. 4

    Installation and reinforcement

    We install the new hardware and, where needed, reinforce the strike, door edge or frame so the lock is not defeated by force. On doors with security bars or tight clearances we work carefully to avoid damaging the surrounding hardware.

  5. 5

    Testing and key handoff

    We test the lock repeatedly, confirm smooth operation, and hand over your keys along with guidance on how key duplication works for your system, so you know who can and cannot copy them.

What affects the price

  • The type and grade of lock: a high security deadbolt cylinder differs from a full restricted-keyway system with controlled key duplication.
  • The number of doors or units, especially for landlords rekeying or upgrading several apartments at once.
  • Door and frame condition: reinforcing a worn frame, strike plate or door edge adds parts and labor.
  • Whether the doors are standard residential, metal security doors, or commercial storefront doors, which use different hardware.
  • How many keys you need and whether you want a master key or keyed-alike arrangement.
  • Time of service: after-hours and emergency calls are handled differently than scheduled daytime visits.

Why Lawndale chooses us

  • Fully mobile and 24/7, so work happens at your door rather than at a shop counter.
  • In business since 1987, with owner and lead tech David Shar overseeing the work.
  • We look at the whole door system, including frame, strike and hinges, not just the cylinder.
  • We will tell you when a high security lock is overkill and a quality standard deadbolt will do.
  • Experience with the mix of Lawndale properties: small-lot stucco homes, barred doors, older apartment buildings and Hawthorne Boulevard storefronts.
  • Clear explanations of how restricted keys work, so you understand what protection you are actually getting.

High Security Locks across Lawndale

Lawndale's housing mix shapes what people ask us for. In El Camino Village and Lawndale Acres, many homes are 1950s and 60s single-family stucco houses on small lots, often with security bars on doors and windows and original knob-and-deadbolt hardware long past its service life. Upgrading to a pick- and bump-resistant deadbolt, with a reinforced strike, is one of the most practical improvements for these homes in ZIP code 90260.

Apartment buildings are everywhere in town, many dating from the 1960s through the 1980s. A landlord of a building off Inglewood Avenue, for example, may need several units rekeyed after move-outs. A restricted key system helps because tenants and former tenants cannot simply duplicate keys, and keyed-alike or master options can give maintenance staff access without a ring of mismatched keys.

Along the Hawthorne Boulevard corridor (SR-107) and nearby Redondo Beach and Artesia Boulevards, small retail tenants often inherit locks and keys from previous occupants or lose control of keys after an employee leaves. In ZIP code 90261 and around the commercial strip, we can install a high security storefront lock and issue new, controlled keys. Whether you are near the Lawndale Civic Center, Lawndale High School or the edge of Alondra Park, call (323) 997-8867 and we will come to you.

High Security Locks in Lawndale — FAQs

What makes a lock high security?
High security locks resist common attacks: picking, bumping and drilling. They typically use tighter tolerances, special pin designs and hardened components, and many use restricted keys that cannot be freely copied.
Are high security locks worth it for a small Lawndale house?
It depends on the door and your concerns. If your home has original builder-grade hardware, an upgraded deadbolt with a reinforced strike can be a meaningful improvement. Call (323) 997-8867 and we will give you an honest recommendation.
Can you install them on a door with security bars?
Yes. Security-barred doors are common in older Lawndale homes, and we work carefully around the bars and frame so the installation does not damage them.
Can my landlord or property manager have all units keyed alike or on a master system?
Yes. We can set up several units with a keyed-alike or master arrangement so maintenance can access them, while restricted keys help control duplication. Call (323) 997-8867 to discuss a multi-unit job.
Can anyone copy a restricted key?
Restricted keyways are designed so duplication is controlled and requires authorization, unlike standard keys cut at any kiosk. We explain exactly how your system works when we hand over the keys.
Do you handle storefront locks on Hawthorne Boulevard?
Yes. We install and rekey commercial and storefront locks, including after an employee leaves and keys need to be replaced.
Do I have to come to your shop?
No. We are fully mobile with no storefront. A technician comes to your home or business anywhere in Lawndale, and we are available 24/7.
Will a high security lock stop a forced break-in?
No lock is unbeatable. A high security lock is strongest when the door, frame and strike are also solid, which is why we inspect and reinforce them. Call (323) 997-8867 for an assessment.
