Rancho Palos Verdes is a place where people often leave big views and long driveways behind a single deadbolt. Many homes here are 1960s and 70s ranches and mid-century designs that still carry their original builder-grade hardware, and alongside them sit newer custom ocean-view estates with electronic gates and expensive doors. A standard lock on either type of property is often the weakest part of an otherwise well-built house.

High security locks address specific, known ways that ordinary cylinders are defeated: picking, bumping, drilling, and the copying of keys without your knowledge. A true high-security cylinder uses tighter tolerances, hardened inserts, security pins and, in many cases, a restricted keyway so that duplicates can only be cut with your authorization. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar and the team bring that experience to every installation.

We are a mobile-only service. There is no storefront to drive to; we bring the hardware, tools and know-how to your door, whether that is a front entry off Crest Road, a side door on a hillside contemporary, or a pedestrian gate at the edge of a gated community. The goal is to match the right level of protection to the actual door, frame and risk, not to sell the most expensive cylinder available.

How it works in Rancho Palos Verdes

  1. 1

    Talk through your concerns

    Call (323) 997-8867 any time. We ask what prompted the upgrade: a recent sale, a break-in nearby, lost keys, or simply wanting better protection. We also ask about the doors and gates involved so we arrive prepared.

  2. 2

    Assess the door, frame and existing hardware

    A strong cylinder is only as good as the door around it. On site we look at the deadbolt, strike plate, screws, door edge and frame. Older ranch homes often have thin strikes and short screws that matter as much as the lock itself.

  3. 3

    Check for ground-shift problems

    In and near the Portuguese Bend landslide area, doors can rack and bind as the ground moves. If a door does not latch cleanly, we address alignment first, adjusting the strike, re-mortising or realigning, because a high security lock fights a misaligned door.

  4. 4

    Choose the right cylinder and key control

    We explain the options in plain terms, including pick-, bump- and drill-resistant cylinders and restricted keyways with controlled duplication. You decide how much key control suits your household, rental or estate.

  5. 5

    Install and reinforce

    We fit the new hardware, reinforce the strike and frame where needed, and make sure the bolt throws smoothly and fully. For estates, we can match multiple exterior doors and the pedestrian gate to a single key.

  6. 6

    Test and hand over keys

    We operate every lock repeatedly, confirm the door closes and latches properly, and hand over your keys along with guidance on who can have copies made.

What affects the price

  • The grade and type of cylinder chosen, from a single high-security deadbolt to a full restricted-keyway system
  • The number of locks, doors and gates to be done, including side doors, garage entries and pedestrian gates
  • Whether the door or frame needs reinforcement, such as a stronger strike plate, longer screws or frame repair
  • Door misalignment from ground movement, which may need strike adjustment or re-mortising before the new lock works properly
  • Exterior conditions, since salt air near the coast can mean choosing corrosion-resistant finishes for gates and outdoor hardware
  • Time of the call, including after-hours or urgent same-night service

Why Rancho Palos Verdes chooses us

  • Fully mobile and 24/7, so we come to your property instead of asking you to visit a shop
  • In business in Greater Los Angeles and Ventura County since 1987, with the owner, David Shar, involved in the work
  • We look at the whole door system, not just the cylinder, because frames and strikes are common weak points
  • Familiarity with hillside and coastal conditions, including doors that bind from ground movement and gate hardware that corrodes
  • Honest recommendations: we will tell you when a mid-range upgrade is enough and when restricted keys make sense
  • One key can be set up across multiple doors and gates for larger properties

High Security Locks across Rancho Palos Verdes

Rancho Palos Verdes spreads across a long peninsula, and security needs vary a lot from one pocket to the next. In Miraleste and Eastview, many homes are mid-century stucco ranches whose original locks have been worn down over decades. Del Cerro and Mediterania mix established homes with newer construction, where owners often want upgraded entry hardware that matches modern doors. Our service area covers ZIP codes 90275 and 90274, and we regularly travel along Palos Verdes Drive South, Palos Verdes Drive East, Hawthorne Boulevard and Crest Road.

The Portuguese Bend landslide area is a special case. Continuous ground movement can rack door frames and bind deadbolts, so a lock that worked last year may stop latching. Before installing anything new, we check alignment and, where needed, adjust strike plates, re-mortise, or realign locksets so the door closes correctly. A high-security cylinder installed in a binding door will not perform as intended, so we fix the fit first.

The coast brings its own wear. Near Point Vicente Lighthouse, Abalone Cove and Terranea Resort, salt air can freeze or corrode gate locks and padlocks, and we replace those with hardware suited to the exposure. Around Trump National Golf Club and other gated hillside estates, a common job is rekeying after a sale, covering the pedestrian gate and several exterior doors so previous keyholders no longer have access. We are mobile only, so we bring everything to the property.

High Security Locks in Rancho Palos Verdes — FAQs

What makes a lock high security?
High-security locks resist the common attack methods: picking, bumping and drilling. They typically use tighter tolerances, hardened components and often a restricted keyway so keys cannot be copied freely. Call (323) 997-8867 to discuss which fits your doors.
Do you have a shop I can visit?
No. Crenshaw Lock Company is fully mobile. We come to your home or property in Rancho Palos Verdes, and we are available 24/7.
My door binds in the Portuguese Bend area. Will a new lock fix it?
Not by itself. Ground movement can rack the frame so the bolt no longer lines up. We adjust strike plates, re-mortise or realign the lockset so the door latches, then install the lock. Call (323) 997-8867 to describe the problem.
Can you rekey a gated estate after a purchase?
Yes. We can rekey or replace the cylinders on multiple exterior doors and the pedestrian gate so they work on one new key, and previous keys no longer work. Electronic gate systems are separate from the mechanical locks we handle on site.
Will salt air damage my gate lock?
It can. Near the coast, salt corrodes mechanisms and can freeze them up. We replace damaged gate locks and padlocks with options better suited to the exposure.
What is a restricted key?
A restricted key uses a keyway that is controlled, so copies generally cannot be cut at an ordinary hardware counter without authorization. It helps you keep track of who has access, which is useful for rentals and larger households.
Does a high security lock help if my door is weak?
Only partly. Strike plates, frames and screws matter just as much as the cylinder, so we inspect and reinforce them during installation.
How do I get an estimate?
Call (323) 997-8867 and tell us about the doors, gates and your goals. Price depends on factors like cylinder type, quantity, door condition and timing, and we explain them before work begins.
