A deadbolt is only as good as the door, the strike, and the screws that hold it in place. In Malibu, there is one more factor most of the country never considers: the ocean. Salt air creeps into every exterior lock along the coast, and a deadbolt that looked fine at installation can turn gritty, stiff, and finally seized within a few seasons. Choosing the right deadbolt here is as much about materials as it is about security grade.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and our owner and lead technician, David Shar, has spent decades on doors of every age and type. We are fully mobile. There is no storefront to visit; we come to your property, whether it is a beach cottage, a hillside custom home, or a rebuilt house with brand-new doors, and we work at any hour of the day or night.

This page explains how a deadbolt installation works on a Malibu home, what affects the cost, how we handle coastal corrosion and gated properties, and answers the questions we hear most often. If you already know what you need, call (323) 997-8867 and we will talk through your door.

How it works in Malibu

  1. 1

    Talk through the door and the goal

    We start with a call. Tell us whether you want a first deadbolt, a replacement for a worn or corroded one, or an upgrade after a break-in scare. We ask about the door material, whether it is exterior or interior, how close you are to the water, and whether you prefer a key, a keypad, or a smart lock.

  2. 2

    Inspect the door, frame, and strike

    On site, we check the door thickness, the existing bore holes, the edge, and the frame. A strong deadbolt in a weak frame still fails, so we look at the strike plate, the jamb, and the screws. Older beach cottages often have softened wood or tired frames that need reinforcement.

  3. 3

    Choose single or double cylinder and the right finish

    A single-cylinder deadbolt uses a key outside and a thumb turn inside. A double-cylinder needs a key on both sides, which can matter near glass but raises exit concerns in an emergency. For oceanfront homes we recommend stainless or marine-grade hardware that resists salt corrosion.

  4. 4

    Install and reinforce

    We prepare the door, fit the bolt and cylinder, and mount a properly aligned strike plate with long screws that reach the framing. If the door needs a new bore or an edge repair, we handle that on site so the bolt throws cleanly and fully.

  5. 5

    Test, key, and hand over

    We cycle the bolt many times with the door open and closed, check the alignment, and confirm the keys work smoothly. If you want several doors keyed alike, or a rekey of existing locks to match, we can set that up during the same visit.

What affects the price

  • Lock grade and material: standard finishes cost less than stainless or marine-grade hardware, which is often the wiser choice close to the beach.
  • Single versus double cylinder, and whether you want a keyed, keypad, or smart deadbolt.
  • Door and frame condition: a door needing new bore work, edge repair, or a reinforced strike takes more labor and parts.
  • Number of doors, and whether you want them keyed alike or rekeyed to match existing locks.
  • Removal of a seized or corroded old deadbolt, which can take extra effort on salt-exposed doors.
  • Time and location of the visit, including after-hours service and any gate or access coordination at the property.

Why Malibu chooses us

  • Fully mobile and available 24/7, so installation happens at your door rather than at a shop.
  • In business since 1987, with the owner, David Shar, personally leading the work.
  • Honest hardware advice for the coast: we point you to stainless or marine-grade options when salt air will shorten the life of ordinary brass or plated finishes.
  • We look at the whole door system, not just the lock, including the frame, strike, and screws that determine real strength.
  • Comfortable with gated and managed properties, and with coordinating access through guard gates when needed.
  • We explain single versus double cylinder tradeoffs plainly, including the safety side of keyed-both-sides locks.

Deadbolt Installation across Malibu

Malibu stretches along Pacific Coast Highway (SR-1), and the right deadbolt depends on where along it you live. In Point Dume, many homes sit close enough to the water that exterior hardware takes a daily beating from salt and wind. Vacation rentals around Point Dume also come up often: owners want a fresh rekey or a new deadbolt between guests, sometimes paired with a lockbox or smart lock. In ZIP code 90265, we regularly see beach cottages with older doors that need both a new deadbolt and a stronger strike plate.

In the private Malibu Colony, homes are gate-guarded and often use multipoint or smart locks. When a smart lock fails, a mechanical override may be needed, and we coordinate access through the guard gate. Along Carbon and Broad Beach, exterior locks seized by salt air call for marine-grade deadbolt replacement, and sometimes gate hardware too. Big Rock, with its hillside views and mix of older and rebuilt homes, brings similar needs, and many wildfire-rebuilt houses have new doors that deserve a quality deadbolt from the start.

We reach homes off Kanan Dume Road, Malibu Canyon Road, Las Flores Canyon Road, and Topanga Canyon Boulevard, as well as canyon and hillside areas such as Malibu Park and Serra Retreat, and mobile-home and beach communities like Paradise Cove and Point Dume Club. Whether your address falls in 90265, 90263, or 90264, call (323) 997-8867 and we will come to you.

Deadbolt Installation in Malibu — FAQs

Why do deadbolts fail so quickly in Malibu?
Salt air corrodes brass, plated finishes, and internal springs, especially on doors facing the ocean. Over time the bolt gets stiff or seizes. Stainless or marine-grade deadbolts resist this far better, so we recommend them for exterior doors near the beach.
Can you replace a seized deadbolt on a beachfront home?
Yes. We remove the corroded lock, check the door and frame for damage, and install a marine-grade replacement. If gate hardware is also corroded, ask about it when you call (323) 997-8867.
Do you offer deadbolt installation at night or on weekends?
Yes. We are available 24/7 and fully mobile. Call (323) 997-8867 any time, and we will talk through your situation and arrange a visit to your property.
Should I choose a single- or double-cylinder deadbolt?
Single-cylinder is easier for exiting quickly and suits most doors. Double-cylinder requires a key on both sides and is sometimes used near glass panels, but it can slow escape in an emergency. We will help you weigh the tradeoffs for your door.
Can you install a smart deadbolt?
Yes, we can install keypad and smart deadbolts. We also suggest keeping a mechanical key override, since gated communities like Malibu Colony may need physical access if electronics fail.
I run a vacation rental near Point Dume. Can you help between guests?
We can rekey or replace deadbolts and help set up a lockbox or smart lock so old codes and keys stop working. Call (323) 997-8867 to plan around your guest schedule.
Will a new deadbolt actually make my door more secure?
It helps, but only if the door and frame can support it. We check the strike plate, jamb, and screws and reinforce them as needed, so the deadbolt performs the way it should.
Do you have a shop I can visit?
No. We are mobile only. We come to your Malibu home, so there is nothing to drop off or pick up.
