A standard builder-grade deadbolt is built to a price, not to resist someone who knows what they are doing. High security locks are different. They use tighter tolerances, hardened inserts that frustrate drilling, more complex pin arrangements that resist picking and bumping, and keys that cannot be copied at a hardware store kiosk without authorization. For some Santa Monica doors, that upgrade is simply sensible.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has watched high security hardware evolve over those decades. We are fully mobile, so there is no storefront to visit. We come to the door, look at how it is built and how it is used, and recommend hardware that fits the door instead of selling the same cylinder to everyone.

In Santa Monica the conversation often involves more than picking a strong cylinder. Salt air eats at exterior hardware, older bungalow doors have worn or oddly bored preps, rental buildings change hands frequently, and storefronts and condo buildings have their own key-control needs. A good high security installation accounts for all of that.

How it works in Santa Monica

  1. 1

    Talk through the threat and the door

    Call (323) 997-8867 any hour. We ask what you are protecting, who has keys now, and whether you have had a break-in, a lost key, or a tenant change. That tells us whether you need maximum pick and drill resistance, key control, or both.

  2. 2

    Inspect the door, frame, and existing hardware

    A strong cylinder in a weak door is a wasted upgrade. On site we check the bore, the strike, the frame, the thickness of the door, and the condition of the existing lock, including any salt-air corrosion on exterior parts.

  3. 3

    Choose the cylinder and key system

    We explain the options: pick- and bump-resistant cylinders, hardened drill-resistant components, and restricted keyways where duplication is controlled. We also discuss whether you want keyed-alike locks across several doors or separate keys for each.

  4. 4

    Install and fit the hardware properly

    We install the deadbolt or cylinder, check bolt throw and alignment, and reinforce the strike where it makes sense. If a door has a nonstandard prep, we adapt it carefully rather than forcing parts to fit.

  5. 5

    Test, hand over keys, and explain key control

    We cycle the lock repeatedly, confirm every key works smoothly, and explain how the restricted keys are handled, including how to get additional copies if you need them later.

What affects the price

  • The grade and brand of cylinder you choose, since restricted-keyway, drill-resistant systems cost more than basic upgrades.
  • The number of locks or doors, and whether they should be keyed alike or kept on separate keys.
  • The condition of the door and frame, including whether a worn, corroded, or oddly bored door needs extra prep work or a reinforced strike.
  • The type of door, such as a wood bungalow door, a metal apartment door, or an aluminum storefront door, which affects hardware compatibility.
  • Whether you need after-hours or emergency service versus a scheduled appointment.
  • The number of restricted keys you want cut at installation.

Why Santa Monica chooses us

  • Fully mobile since 1987, so the recommendation is made while looking at your actual door instead of over the counter.
  • Owner-led experience: David Shar has decades of hands-on work with deadbolts, rekeys, and security upgrades.
  • We look at the whole door, because a high security cylinder only helps if the door and strike can back it up.
  • We account for Santa Monica salt air when suggesting finishes and hardware for exposed exterior doors and gates.
  • Available 24/7, including after a break-in when a lock needs to be replaced right away.
  • Straightforward advice, including telling you when a simpler solution is enough.

High Security Locks across Santa Monica

Santa Monica's housing mix shapes what high security locks make sense. In Ocean Park and Sunset Park, many 1920s Craftsman and Spanish bungalows sit close enough to the coast that salt air corrodes exterior deadbolts, padlocks, and gate latches. Replacing a seized deadbolt with a quality high security cylinder is a common upgrade, and choosing a durable finish matters as much as the pick resistance.

North of Montana, period-revival homes often have original or custom doors that deserve careful fitting rather than drastic modification. Around Montana Avenue, Pico, and Wilmont, rent-controlled and mid-century courtyard apartments see regular tenant turnover, which makes restricted keys useful, because landlords can control who is able to copy a key. Downtown, newer mixed-use condos usually rely on fobs and intercoms, but unit entry doors can still benefit from a stronger cylinder.

We serve ZIP codes 90401, 90402, 90403, 90404, and 90405, from the retail units along Third Street Promenade and near Santa Monica Place to offices around Bergamot Station and homes near Santa Monica College. Whether you are off Lincoln Blvd, Wilshire Blvd, or Ocean Ave, call (323) 997-8867 and we will come to you.

High Security Locks in Santa Monica — FAQs

What makes a lock high security?
High security locks combine tighter manufacturing tolerances, pick- and bump-resistant internal designs, hardened parts that resist drilling, and often restricted keys that are harder to duplicate. Call (323) 997-8867 to discuss which level suits your door.
Will a high security lock stop a break-in by itself?
Not alone. Many break-ins involve kicking the door or attacking the frame, so we also check the strike, frame, and door condition. The best results come from strong hardware on a solid door.
Is salt air a problem for high security locks in Santa Monica?
Yes, especially near the beach in Ocean Park and Sunset Park. Salt air can seize exterior deadbolts, padlocks, and latches. We can suggest suitable finishes and hardware for exposed doors, and replace already seized locks.
Can landlords use high security locks between tenants?
Yes. With restricted keys, a landlord has better control over who can copy keys, which helps in rent-controlled buildings with frequent turnover. Call (323) 997-8867 to arrange rekeying or upgrades for one or several units.
Can you install high security locks on a storefront?
Often yes, including aluminum storefront doors like those at Third Street Promenade retail units. Door type affects which cylinders and locks fit, so we check the door first.
Do you have a shop I can visit?
No. Crenshaw Lock Company is fully mobile, so we come to you in Santa Monica and handle the work at your door.
Can I get extra keys for a restricted keyway?
Yes, through the proper authorization process for that system. We explain how it works at installation so you know how to get more keys later.
Do you offer emergency installs?
We are available 24/7. If you have had a break-in or lost keys and need a stronger lock right away, call (323) 997-8867.
