A high security lock is not simply a more expensive deadbolt. It is a lock built to resist the specific ways doors actually get defeated: picking, bumping, drilling, forced turning, and the quiet copying of keys. In Malibu, where homes can sit at the end of long private drives, behind gates, or on bluffs with ocean views and few neighbors in earshot, the lock on the front door often matters more than it would on a busy suburban street.

Malibu adds a second problem that most lock guides ignore: salt air. Beachfront hardware on stretches like Carbon Beach and Broad Beach corrodes, pits, and eventually seizes. A lock that is strong on paper but made of the wrong finish can fail from the inside out. So our high security work here is as much about choosing marine-grade or stainless hardware as it is about pick resistance.

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, so every consultation happens at your door, where we can see the frame, the strike, the exposure to weather, and how the household actually uses the entry.

How it works in Malibu

  1. 1

    Talk through your risks and your doors

    Call (323) 997-8867 and tell us what you are protecting: a primary residence, a vacation rental, a guest house, a studio, or a gate. We ask about who has keys now, whether keys have been lost, and whether a smart lock or alarm is already in place.

  2. 2

    On-site assessment at your property

    We come to you and inspect the door, frame, strike plate, hinges, and existing hardware. On the coast we check for corrosion, swollen wood, and misaligned doors, because a high security cylinder cannot make up for a weak frame or a door that no longer closes true.

  3. 3

    Match the lock to the door and the environment

    We explain realistic options: restricted-keyway cylinders with controlled key duplication, drill-resistant hardened inserts, anti-bump designs, and stainless or marine-grade bodies for salt exposure. For multipoint doors and smart-lock setups we confirm compatibility before anything is installed.

  4. 4

    Installation and reinforcement

    We install the new hardware, then reinforce what needs it, such as longer strike screws, a heavier strike plate, or a door edge guard. We check that the bolt throws fully and the door latches smoothly without forcing.

  5. 5

    Key setup and handoff

    We cut and test your keys, explain how restricted key copies are authorized, and walk you through operation. If you manage a rental, we can discuss how to handle key control between guests.

  6. 6

    Follow-up guidance

    We tell you how to care for the hardware in a coastal climate, including cleaning and lubrication habits that help it last, and what to do if a key is lost.

What affects the price

  • The grade and brand of lock chosen, since restricted-keyway, drill-resistant and anti-bump designs vary widely in construction and cost.
  • How many doors and cylinders are involved, and whether they should all be keyed alike on one restricted key.
  • Marine-grade or stainless finishes, which are often the right call for beachfront and bluff-top homes exposed to salt air.
  • Door and frame condition, including any reinforcement, strike upgrades, or alignment work needed for the lock to perform properly.
  • Compatibility with multipoint systems, gate hardware, or smart locks already on the property.
  • Number of keys and any restricted key cards or authorization needed for future copies.

Why Malibu chooses us

  • We are fully mobile and available 24/7, so we handle the work at your door instead of asking you to bring hardware anywhere.
  • We have been serving Greater Los Angeles and Ventura County since 1987, so we have seen how different locks hold up over decades.
  • We think about corrosion first on the coast, steering beachfront owners toward stainless or marine-grade hardware rather than a lock that will seize in a few seasons.
  • We look at the whole door, because a strong cylinder on a weak frame or loose strike is only partial security.
  • We tell you plainly when a high security lock is worth it and when a simpler upgrade or rekey would do the job.
  • We are comfortable with gated and multipoint properties and can coordinate with guards or property managers when access has to be arranged.

High Security Locks across Malibu

Malibu stretches along Pacific Coast Highway (SR-1) for miles, and the homes along it could hardly be more varied. In Malibu Colony and along Carbon and Broad Beach, gate-guarded estates often combine multipoint locks, smart locks, and heavy exterior doors. Further up in Point Dume, Malibu Park and Serra Retreat, hillside and canyon custom homes reached by roads like Kanan Dume Rd and Las Flores Canyon Rd often have long private approaches where a hard-to-defeat lock is a real comfort.

We see a few situations repeatedly. A beachfront owner finds the exterior deadbolt corroded and seized by salt air and needs a marine-grade replacement along with gate hardware. A Point Dume vacation rental needs a rekey and a considered key-control plan between guests. And a Malibu Colony home gets locked out when a smart lock fails, where a mechanical override has to be coordinated through the guard gate. Each calls for different hardware and a different approach.

We serve Malibu addresses in ZIP codes 90265, 90263 and 90264, from Big Rock and the Malibu Pier area to Zuma Beach and the neighborhoods near Pepperdine University and the Malibu Country Mart. Many homes here were rebuilt after wildfires, which means newer doors and frames that deserve hardware to match. Call (323) 997-8867 any hour.

High Security Locks in Malibu — FAQs

What makes a lock high security?
It is designed to resist picking, bumping, drilling, and unauthorized key copying. Typically that means a restricted keyway, hardened components, and tighter manufacturing tolerances than a standard builder-grade deadbolt.
Do you offer high security lock installation 24/7 in Malibu?
Yes. We are a fully mobile locksmith available around the clock and come to your Malibu property. Call (323) 997-8867 to discuss your situation.
Will salt air damage a high security lock?
It can if the finish is wrong. Beachfront homes on Carbon Beach or Broad Beach often do best with stainless or marine-grade hardware, and regular cleaning helps any lock last longer in coastal conditions.
Can you replace a lock that has seized from corrosion?
Yes. We can remove corroded deadbolts and gate hardware and install marine-grade replacements. If the lock is already stuck, call (323) 997-8867 and we will plan the safest way to open and replace it.
Is a high security lock worth it for a vacation rental?
Often a rekey between guests plus a lockbox or smart lock is enough, but a restricted-key cylinder helps if you want tighter control over who can copy keys. We can talk through what fits your rental.
Can high security locks work with my smart lock or multipoint door?
In many cases yes, but compatibility depends on the specific system. We check your door and hardware first so the new lock works properly with what is already there.
What if my smart lock fails and I am locked out in a gated community?
Call us at (323) 997-8867. For gated places like Malibu Colony we can coordinate access through the guard gate and use the mechanical override where available.
Do I need a new door or frame?
Not always. We inspect the door and frame on site and recommend reinforcement only where it is needed so the lock can do its job.
