A lock is only as good as the cylinder, the strike, the door and the key control behind it. In Manhattan Beach, where homes range from compact Sand Section cottages to large custom estates on the Hill, the right high security upgrade looks different from one property to the next. Our work is to match the hardware to the door and to the way you actually live in the house.

High security locks resist the common ways a standard deadbolt gets defeated: picking, bumping, drilling and forced cylinder removal. They typically pair hardened internal components with a restricted keyway, meaning copies can only be made with proper authorization. That matters after a housekeeper, contractor or tenant change, or when a vacation home has been handled by several people 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, so every job begins with a conversation about your doors and ends with the work done at your property.

How it works in Manhattan Beach

  1. 1

    Talk through your doors and concerns

    Call (323) 997-8867 and tell us what you have: a standard deadbolt, a multipoint European system, a keypad or smart lock. We ask about who has keys, whether the home is a primary or second residence, and what prompted the upgrade.

  2. 2

    Assess the door, frame and existing hardware

    A strong cylinder in a weak door or a loose strike still fails. On site we check the door thickness, the frame, the strike plate and screws, and any corrosion, which is common on coastal homes near the Strand.

  3. 3

    Recommend hardware that fits

    We explain the options for resisting picking, bumping and drilling, and whether a restricted key system makes sense. For multipoint doors we work with the existing mechanism rather than forcing a mismatched part.

  4. 4

    Install and reinforce

    We fit the new cylinders or deadbolts, reinforce strikes where needed, and confirm that the door latches and throws smoothly. If you want several doors keyed alike, we set that up during the same visit.

  5. 5

    Cut keys and review key control

    We test every key, explain how restricted copies are obtained, and discuss who should hold them. If you use a keypad or smart lock, we can reprogram codes and keep a mechanical backup.

  6. 6

    Final check and walkthrough

    Before we leave, we operate each lock with you, confirm the doors secure properly from inside and out, and answer care questions, including how to protect hardware from salt air.

What affects the price

  • The number of doors, gates and garage entries being upgraded, and whether you want them keyed alike.
  • The type of hardware chosen, such as a restricted-keyway cylinder, a high security deadbolt or a multipoint system component.
  • The condition of the door, frame and strike, including whether reinforcement or replacement of seized, corroded parts is needed.
  • Whether smart locks or keypads must be reprogrammed or integrated alongside a mechanical backup key.
  • Key quantity and the level of key control or authorization you want for duplicates.
  • Timing and location of the visit, including after-hours or urgent requests, since we are available around the clock.

Why Manhattan Beach chooses us

  • Fully mobile service: we bring the tools and parts to your door rather than asking you to visit a shop, because we have no storefront.
  • Experience since 1987, with owner David Shar leading the work, so you are dealing with someone who has seen many door and lock types.
  • Comfort with multipoint European-style hardware, common on new luxury construction, rather than only standard deadbolts.
  • Honest recommendations: if your existing lock is fine and the real weakness is the strike or frame, we will say so.
  • Attention to coastal wear, since salt and sand can seize or corrode exterior hardware near the beach.
  • Available 24/7, so a lockout or security concern after a break-in attempt does not have to wait until morning.

High Security Locks across Manhattan Beach

Manhattan Beach has a mix of homes that each present a different security question. In the Sand Section, walk-street cottages and newer three-story contemporary homes sit on small lots close to the Strand and the Manhattan Beach Pier. Front doors are often exposed to salt air, and many newer builds use multipoint European door systems where the gearbox, not just the cylinder, has to be serviced properly. Pedestrian gates and garage access points deserve the same attention as the front door.

Up in the Hill Section, large custom estates often combine keypads and smart locks with traditional hardware. A common request is to reprogram access codes and cut a backup mechanical key after a housekeeper or contractor change. In the Tree Section, mid-century ranch homes are steadily giving way to new builds, and remodels frequently leave behind mismatched or salt-seized deadbolts that are good candidates for replacement and keying alike. East Manhattan Beach adds townhomes and condos, where shared entries and individual unit doors call for their own planning.

Whether you are in ZIP code 90266 near Metlox Plaza, Polliwog Park or Manhattan Village, or just off Sepulveda Blvd, Rosecrans Ave, Manhattan Beach Blvd, Aviation Blvd or Marine Ave, we come to you. Many owners here also have second homes or vacation properties, so we can coordinate work around your schedule and help you control who holds keys.

High Security Locks in Manhattan Beach — FAQs

What makes a lock "high security"?
These locks resist picking, bumping and drilling through hardened components and tighter internal tolerances. Many also use restricted keyways so copies cannot be made freely. Call (323) 997-8867 and we can explain which fits your doors.
Can you work on multipoint European-style door systems?
Yes. Many new Sand Section homes use them, and a lockout or malfunction often involves the gearbox rather than a simple deadbolt. We assess the mechanism and service or replace the correct components.
Will a high security lock help if my door frame is weak?
Not by itself. A strong cylinder still depends on the door, strike and screws. We inspect and reinforce those parts as part of the job.
We changed housekeepers. Should we rekey or upgrade?
Rekeying stops old keys from working, and upgrading to a restricted key system adds control over future copies. We can reprogram a keypad or smart lock and cut a mechanical backup. Call (323) 997-8867 to plan it.
Does salt air affect my exterior locks?
Yes. Salt and sand can corrode and seize deadbolts, especially closer to the beach. We can replace worn hardware and talk through finishes and upkeep that hold up better.
Can all my doors be keyed alike?
Usually yes. After a remodel, many Tree Section owners prefer one key for every exterior door. We set that up as part of the installation.
Do you have a shop I can visit?
No. We are fully mobile only and come to your home anywhere in Manhattan Beach.
Are you available outside normal hours?
Yes, we are available 24/7. If you are locked out or worried about security, call (323) 997-8867 at any time.
