A standard builder-grade deadbolt is designed to keep honest people honest. A high security lock is built for a different problem: someone who actually tries to defeat the cylinder by picking, bumping, drilling or forcing it. In a city as varied as Long Beach, with waterfront homes, dense apartment blocks, downtown high-rises and an industrial west side near the Port, the right upgrade depends heavily on the building and on what you are protecting.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has spent decades working with everything from antique mortise sets to modern restricted-keyway cylinders. We are fully mobile, so there is no storefront to visit. We come to your door, look at the hardware and the door itself, and recommend something that fits instead of selling you the same product for every job.

High security is more than a cylinder. A drill-resistant lock on a thin, split or poorly fastened door frame still leaves a weak point. We look at the whole entry: the cylinder, the bolt, the strike plate, the screws, and the frame, and we explain where the real risk sits so you can decide what is worth doing.

How it works in Long Beach

  1. 1

    Talk through what you are protecting

    Call (323) 997-8867 any hour. We ask about the door, the building type, who has keys now, and whether you are worried about a specific threat such as lost keys, a former tenant, or past break-in attempts.

  2. 2

    On-site assessment at your door

    A technician comes to you and examines the existing lock, door thickness, frame, strike plate and surroundings. In a coastal area like Naples or Belmont Shore, we also check for salt corrosion that may affect any hardware we install.

  3. 3

    Choose the right level of hardware

    We explain options such as restricted keyways, pick- and bump-resistant cylinders, hardened drill-resistant components and, where it makes sense, electronic or keypad systems. We tell you honestly what each one does and does not stop.

  4. 4

    Installation and reinforcement

    We install the new cylinders or deadbolts, and where needed reinforce the strike plate, frame or door edge with longer screws and stronger hardware. For older homes, we work to preserve the look of original doors wherever we can.

  5. 5

    Key control and testing

    We test every lock and key, make sure the bolt throws fully and the door closes cleanly, and explain how restricted keys are duplicated so you know who can and cannot copy them.

  6. 6

    Rekeying and follow-up options

    If you have multiple doors, we can key them alike or separately and note what to do when keys are lost or an occupant changes, so your security stays intact over time.

What affects the price

  • The grade and type of lock: restricted-keyway mechanical cylinders, hardened deadbolts and electronic systems sit at very different cost levels.
  • The number of doors and cylinders, and whether you want them keyed alike or each on its own key.
  • The condition of the door and frame, since reinforcing a weak strike plate or frame adds parts and labor.
  • Older or specialty hardware, such as mortise locks in 1920s Craftsman and Spanish Colonial homes, which may need custom fitting or sympathetic retrofits.
  • Environmental demands, such as marine-grade or corrosion-resistant components for canal and beachfront properties.
  • Time and location of the visit, including after-hours or emergency service, which we can explain when you call.

Why Long Beach chooses us

  • Fully mobile service: we bring the tools and hardware to your door anywhere in Long Beach, and there is no shop to drive to.
  • Operating since 1987 under owner and lead tech David Shar, with long experience across modern and antique hardware.
  • Whole-door thinking: we look at frame, strike and fasteners, not just the cylinder, so the upgrade actually improves security.
  • Respect for historic homes: we try to retrofit or repair original mortise hardware in older doors instead of defaulting to replacing it.
  • Straight talk about limits: no lock is unbeatable, and we will tell you when a cheaper option is enough or when a higher level is justified.
  • Available 24/7, so a break-in or lost-key scare does not have to wait until morning to be secured.

High Security Locks across Long Beach

Long Beach asks a lot of a lock. In Naples and Belmont Shore, salt air and moisture shorten the life of ordinary cylinders, so corrosion-resistant, marine-grade hardware often matters as much as pick resistance. Canal homes and bungalows near Shoreline Village and the Peninsula are good candidates for sturdier cylinders paired with a properly reinforced door. Properties in ZIP 90803 in particular benefit from a check of how the weather has treated existing hardware.

The historic districts of California Heights and Belmont Heights have another challenge: many 1920s Craftsman and Spanish Colonial homes still have original mortise locks and period doors. Owners there usually want better protection without losing the character of the house. We can often service or sympathetically retrofit the original hardware, and add high security cylinders where the door allows. In Bixby Knolls and Wrigley, where mixes of single-family homes and apartments are common, rekeying with restricted keys helps landlords and residents control who has copies.

Downtown Long Beach and Alamitos Beach (ZIP 90802 and 90814) have condos, lofts and apartments, many with HOA rules or electronic access that affect what you can change. Around CSULB (ZIP 90815) rentals turn over often, which makes key control valuable. Whether you are near the Queen Mary, the Aquarium of the Pacific, The Pike Outlets or off I-710, I-405 or PCH, call (323) 997-8867 and we will come to you.

High Security Locks in Long Beach — FAQs

What makes a lock "high security"?
Typically a combination of pick-resistant and bump-resistant cylinder design, hardened drill-resistant parts, and a restricted keyway so keys cannot be casually copied. Call (323) 997-8867 and we can explain what fits your door.
Can a high security lock be installed on any door?
Most doors can take one, but the door and frame matter. A thin door or weak frame may need reinforcement so the lock is not the only strong part of the entry. We assess this on-site.
Do you serve both homes and businesses in Long Beach?
Yes. We handle houses, apartments, condos and commercial doors across Long Beach, including areas near the Port. Our service is fully mobile and available 24/7.
I live in a historic Craftsman in California Heights. Do I have to replace my original lock?
Not necessarily. Original mortise locks can often be repaired, rekeyed or sympathetically upgraded. We aim to preserve period hardware where it is practical and still improve security.
Will salt air near Naples or Belmont Shore damage my new lock?
Coastal air does accelerate corrosion. We can discuss corrosion-resistant or marine-grade hardware, and regular cleaning and lubrication help any lock last longer. Call (323) 997-8867 for advice.
Can high security keys be copied at a hardware store?
Restricted keys are designed so they generally cannot be duplicated without authorization. That makes them useful for landlords, shared properties and anyone who wants better control of copies.
Can you help if I live in a condo with HOA access rules?
Often yes, but HOA rules may limit what can be changed on entry doors or shared access systems. Check your rules and call us, and we will work within them.
Do you have a shop I can visit?
No. Crenshaw Lock Company is mobile only. Our technicians come to your location in Long Beach at any hour of the day or night.
