A standard builder-grade deadbolt is designed to keep an honest person honest. High security locks are built for a different job: they resist picking, bumping and drilling, and they pair with keys that cannot be casually copied at a hardware-store kiosk. For many La Mirada households and businesses, that upgrade is a practical way to control who has access, not just who can walk in.

La Mirada is a master-planned suburb incorporated in 1960, and much of it is rows of single-story 1950s and 60s ranch homes on uniform lots. Many of those houses still carry the original hardware or locks that have passed through several owners, with an unknown number of keys floating around. Add townhome and condo communities run by HOAs, the institutional hardware at a campus like Biola University, and the commercial strips along Rosecrans Ave and Imperial Hwy, and you have a wide range of doors that benefit from better cylinders.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987 under owner and lead technician David Shar. We are mobile only, with no storefront, so every job begins with a conversation and a look at your actual door. We will tell you honestly whether a high security cylinder is the right fit, or whether a simpler fix such as a reinforced strike plate would solve your problem.

How it works in La Mirada

  1. 1

    Talk through your concern

    Call (323) 997-8867 and tell us what is driving the upgrade: a break-in attempt, a recent move, lost keys, a tenant turnover or a general desire for stronger protection. That shapes which lock and key system makes sense.

  2. 2

    Assess the door and existing hardware

    We come to you and inspect the door, frame, strike plate and current lock. A pick-resistant cylinder is only as strong as the door around it, so we check for thin jambs, short screws and weak strikes.

  3. 3

    Choose the right level of protection

    We explain the options in plain language: pick-, bump- and drill-resistant cylinders, restricted keyways where key duplication is controlled, and how each fits your budget and how many people need keys.

  4. 4

    Install and reinforce

    We fit the new high security lock, align it with the door, and reinforce the strike and frame where needed. Doors that have been painted or shifted over decades often need adjustment to latch smoothly.

  5. 5

    Test and hand over keys

    We operate the lock repeatedly with the door open and closed, confirm every key works, and explain how to order additional keys so you stay in control of copies.

What affects the price

  • The type of lock and cylinder chosen, since restricted-keyway and drill-resistant models vary in cost and complexity.
  • How many locks need upgrading, such as a single front door versus every exterior door in a ranch home or a full HOA common area.
  • The condition of the door and frame, including whether the strike plate, jamb or door edge needs reinforcement.
  • Whether you want keyed-alike cylinders so one key operates several doors.
  • The number of keys you need and whether you want a controlled key system for tenants, staff or HOA residents.
  • The time of day and urgency of the visit, since we are available 24/7 and after-hours calls differ from scheduled appointments.

Why La Mirada chooses us

  • Fully mobile service: we work at your door in La Mirada, and there is no shop to drive to.
  • In business since 1987, with owner and lead tech David Shar overseeing the work.
  • Honest recommendations: if a reinforced strike plate or a simple rekey solves your problem, we will say so rather than upsell.
  • Experience across housing types, from 1960s ranch tract homes to townhome HOAs and institutional or commercial doors.
  • Focus on the whole door, not just the cylinder, because a strong lock in a weak frame is not real security.
  • Available 24/7, so a break-in or a lock failure at night can be addressed right away.

High Security Locks across La Mirada

La Mirada's housing tells you a lot about its security needs. Around the La Mirada Civic Center and across East La Mirada, the 1960s ranch homes often have original or aging hardware, and a resale is a natural moment for an upgrade. In ZIP 90638 and 90637, buyers during escrow commonly want to rekey or step up to high security cylinders so that previous owners, agents and contractors no longer hold working keys.

In the Biola University district (ZIP 90639), off-campus student housing turns over regularly, and keys multiply quickly. A restricted-key high security system helps landlords keep track of who holds a copy, and a 24/7 mobile locksmith is useful when a lockout or lost key happens late at night. Townhome and condo communities off Rosecrans Ave face a similar challenge with common-area doors, pool gates and cluster mailboxes shared by many residents.

Whether you live near La Mirada Regional Park, off Valley View Ave or La Mirada Blvd, or run a business along Imperial Hwy or near the I-5, we come to you. Call (323) 997-8867 to discuss your doors, and we will tell you plainly what will and will not improve your security.

High Security Locks in La Mirada — FAQs

What makes a lock "high security"?
High security locks use cylinders designed to resist picking, bumping and drilling, and often use restricted keys that are harder to copy. They are a step above standard builder-grade deadbolts. Call (323) 997-8867 and we can explain which features matter for your door.
Will a high security lock help on an older La Mirada ranch home?
Yes, usually. Many 1950s and 60s homes have original or worn hardware. A better cylinder helps, but we also check the door, frame and strike plate, because weak surroundings can undermine a strong lock.
Can you rekey during escrow on a home purchase?
Yes. Rekeying or upgrading locks at resale is common so that former owners and others no longer hold working keys. We are mobile and 24/7, so you can schedule around your closing.
Do you serve student housing near Biola University?
Yes. We serve the Biola University district and other off-campus housing in ZIP 90639. Restricted keys can help landlords control copies, and we are available at night for lockouts. Call (323) 997-8867.
Can an HOA upgrade common-area locks?
Yes. We can address common-area doors, pool gates and cluster mailbox locks for townhome and condo communities, including keyed-alike or controlled key arrangements, which helps manage access.
Can high security keys still be copied?
Restricted keys are designed so copies generally must be ordered through authorized channels rather than cut at a kiosk. We explain how to order extra keys when we hand the system over.
Do you have a shop I can visit?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to your home or business in La Mirada, and you can reach us 24/7 at (323) 997-8867.
How do you price a high security installation?
Pricing depends on the lock type, number of doors, the condition of the door and frame, key quantities and the timing of the visit. We discuss these factors before work begins so there are no surprises.
