Ladera Heights is a neighborhood of well-kept, larger-lot homes, and many of them still carry the original hardware from the 1950s and 60s. A mid-century ranch house with a standard builder-grade deadbolt, a few side and rear service doors, and decades of copied keys is easy to secure on paper but harder in practice. A high security lock upgrade addresses the real weak points: picking, bumping, drilling, and unauthorized key duplication.

High security locks are different from ordinary hardware in how they are built. They use tighter tolerances, more complex internal pin arrangements, hardened inserts that resist drilling, and restricted keyways, so a key cannot be copied at any hardware counter without proper authorization. Some systems also pair with keypad or smart-lock components for homeowners who want to stop handing out physical keys altogether.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar leads the work. We are mobile only, with no storefront to visit. We bring the hardware discussion, the installation, and the key cutting to your property, whether you are in Upper Ladera Heights, Lower Ladera Heights, or a gated enclave nearby.

How it works in Ladera Heights

  1. 1

    Talk through your concerns by phone

    Call (323) 997-8867 any time, day or night. We ask about the doors you want protected, what hardware is there now, whether you recently bought the home or lost a key, and whether you prefer keys, a keypad, or a combination.

  2. 2

    Walk the property and check every entry

    On arrival we look at the front door, side and rear service doors, garage entry, and any patio or hillside access. We check door thickness, strike plates, frame condition, and how the door is hung, because a strong lock on a weak frame doesn't accomplish much.

  3. 3

    Recommend suitable hardware

    We explain the options in plain language: restricted-keyway cylinders, drill-resistant deadbolts, and keypad or smart-lock add-ons. You decide what fits your home and how you live in it.

  4. 4

    Install and reinforce

    We fit the new locks, adjust the latch and bolt alignment, and reinforce strike plates where needed so the hardware engages properly. Older mid-century doors sometimes need careful fitting, and we take the time to get it right.

  5. 5

    Cut and test keys

    We provide your keys, test each lock repeatedly, and make sure the doors operate smoothly. If you want several doors on one key, we can discuss keying them alike.

  6. 6

    Review key control

    We explain how restricted keys are handled, who can authorize duplicates, and what to do if a key goes missing so you stay in control of access.

What affects the price

  • The number of doors being upgraded, since a front door alone is a different job than front, side, rear, and garage entries.
  • The security level and brand of the lock you choose, including whether it has a restricted keyway and drill-resistant components.
  • Whether existing doors and frames need reinforcement, such as stronger strike plates or adjustments on older mid-century doors.
  • Whether you want keyed-alike doors, extra restricted keys, or a keypad or smart-lock component added.
  • The time of day the work is requested, since we are available 24/7 and after-hours calls can differ from scheduled daytime appointments.

Why Ladera Heights chooses us

  • Fully mobile service, so the whole consultation and installation happens at your home with nothing to drop off.
  • Family-scale experience since 1987 with the kinds of older residential doors common in 1950s and 60s homes.
  • Honest advice about which doors actually need high security hardware and which do not, instead of pushing a full-house upgrade.
  • Attention to door and frame condition, not just the lock, because hardware only performs as well as what it is mounted to.
  • Availability 24/7, including after a sudden need to secure a home following a break-in attempt or a lost key.
  • Clear explanations of restricted keyways and key control so you understand who can copy your keys.

High Security Locks across Ladera Heights

Ladera Heights sits in the hills along La Tijera Boulevard, with La Cienega Boulevard, Slauson Avenue, Centinela Avenue, and La Brea Avenue shaping how people get around. Upper Ladera Heights has view and hillside homes with long driveways and multiple access points, while Lower Ladera Heights is made up largely of mid-century and ranch-style houses on spacious lots. Many of these homes have side and rear service doors that were never upgraded alongside the front entry.

A common situation here is a 1960s ranch home in Upper Ladera Heights that has just changed hands. New owners often want the old key history gone and a stronger setup in its place, covering the front door, side door, and rear service door. Upgrading to restricted-keyway deadbolts, or adding a keypad or smart-lock system on a hillside home, is a practical way to do that. We work throughout ZIP codes 90056 and 90045.

We also help neighbors near Ladera Center, around La Tijera and Centinela, who find themselves locked out. In those cases we use non-destructive entry first, and if a high security upgrade makes sense afterward, we can discuss it right then. With Kenneth Hahn State Recreation Area and West Los Angeles College close by, the area sees plenty of comings and goings, and a well-protected door is simply good housekeeping.

High Security Locks in Ladera Heights — FAQs

What makes a lock high security?
High security locks resist picking, bumping, and drilling through tighter tolerances, complex pin designs, and hardened components. Many also use restricted keyways, so keys cannot be copied freely.
Do you serve Ladera Heights at night?
Yes. We are available 24/7 and fully mobile. Call (323) 997-8867 and we will come to your home in Ladera Heights.
Is it worth upgrading side and rear doors too?
Often yes. In many mid-century ranch homes, side and rear service doors have older hardware and are less visible from the street. We look at each entry and tell you honestly which ones benefit most.
Can you install a keypad or smart lock on a hillside home?
Yes. We can install keypad or smart-lock systems on suitable doors, and we can pair them with a high security deadbolt. Call (323) 997-8867 to discuss what would fit your home.
Should I change the locks after buying a house in Ladera Heights?
It is a smart step. You cannot know who holds copies of the old keys. Rekeying or installing high security cylinders gives you a fresh start with keys only you control.
Can high security keys be copied anywhere?
Restricted keys generally cannot be duplicated at ordinary key kiosks. Copies are made through authorized channels, which is the point of key control.
Will a new lock fit my older door?
Usually yes, though 1950s and 60s doors sometimes need careful fitting or reinforcement. We assess the door and frame on site and make it work properly.
What if I am locked out and also want better locks?
We start with non-destructive entry to get you inside. Afterward we can talk about upgrading. Call (323) 997-8867 any hour.
