A standard builder-grade deadbolt is built to a price, and in Redondo Beach it also has to survive salt air, fog and decades of use. High security locks are a different category of hardware. They use tighter tolerances, hardened steel inserts that resist drilling, pin designs that frustrate picking and bumping, and keys that cannot be copied at a hardware-store kiosk without authorization. For many households this is one of the most worthwhile upgrades you can make to an entry door.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has seen how different the needs are from one Redondo Beach block to the next. A 1940s Spanish home in Hollywood Riviera with corroded exterior hardware is a very different job from a North Redondo townhome with a front door, a garage service door and a rear patio slider that all need to work with one key. We start from the building and the way you live in it, not from a one-size package.

We are mobile only. There is no storefront to visit; we bring the hardware, tools and key-cutting capability to you, whether that is a house near Riviera Village, a condo close to the pier, or a storage unit at King Harbor. Call (323) 997-8867 any hour, and we will talk through what you have now and what would suit it.

How it works in Redondo Beach

  1. 1

    Talk through your goals and your doors

    We begin with a call to learn which doors you want protected, what locks are on them now, and whether the concern is a break-in, a lost key, a tenant change or simply an aging lock. That lets us bring the right hardware on the first visit.

  2. 2

    Inspect the door, frame and strike

    A strong cylinder is only as good as the door around it. On site we check the door thickness, the bore, the latch alignment, the strike plate and the screws, and we look for salt corrosion or swelling common to coastal homes. If the frame is the weak point, we tell you plainly.

  3. 3

    Choose the right level of protection

    We explain the options: pick- and bump-resistant cylinders, drill-resistant hardened inserts, Grade-1 deadbolts, and restricted keyways where key duplication is controlled. We match these to your door and budget instead of pushing the most elaborate setup.

  4. 4

    Install and fit the hardware

    We remove the old lock, install the new deadbolt or cylinder, reinforce the strike where needed, and confirm the bolt throws smoothly and fully. Corroded or worn parts are replaced rather than reused, so the new lock is not undermined by old hardware.

  5. 5

    Key your doors the way you want

    We can key multiple doors alike, so a townhome's front, garage and patio doors open with one key, or keep them separate. We cut and test every key and show you how the restricted key system works for making extras.

  6. 6

    Final test and handover

    Before we leave, we operate every lock from inside and out, check the keys, and review care tips for coastal conditions. You leave knowing what was installed and how to get additional keys.

What affects the price

  • The number of doors or cylinders being upgraded, including front, garage service, patio and gate locks
  • The security grade and cylinder type selected, such as standard Grade-1 versus restricted-keyway drill-resistant hardware
  • Whether the door, bore or frame needs reinforcement or repair before a new lock will perform properly
  • How many keys you need and whether they are restricted keys requiring authorization to duplicate
  • Whether existing hardware is badly corroded or seized and takes extra work to remove
  • Time of day and location, since we are available 24/7 and travel to you as a mobile service

Why Redondo Beach chooses us

  • Fully mobile service: we come to your door in Redondo Beach with hardware on board, and there is no storefront to drive to.
  • Serving Greater Los Angeles and Ventura County since 1987, with owner and lead technician David Shar involved in the work.
  • We evaluate the whole door, frame and strike, not just the cylinder, because a strong lock on a weak frame protects little.
  • Experience with coastal conditions: we recommend and replace hardware with salt exposure and corrosion in mind.
  • Multi-door keying for townhomes and attached homes, so one key can serve the front, garage and patio entries.
  • Straightforward advice: if a simpler upgrade will do the job, we say so rather than upselling.

High Security Locks across Redondo Beach

Redondo Beach splits naturally into South Redondo (ZIP 90277) and North Redondo (ZIP 90278), and the lock needs differ between them. In South Redondo, the hillside homes of Hollywood Riviera include 1920s to 1950s Spanish houses where original exterior deadbolts have often been worn and corroded by decades of ocean air. Replacing them with a Grade-1, drill-resistant cylinder is a common upgrade, and it fits neatly alongside the character of an older home. Closer to Riviera Village and the pier, beach bungalows and condos have their own concerns, from shared entries to doors that see heavy sun and salt.

North Redondo, including El Nido, Golden Hills and The Avenues in 90278, is dominated by attached townhomes and small-lot homes built from the 1980s onward. These typically have several exterior doors, a garage service door, a patio slider or rear door, and sometimes HOA gate or garage access. A new owner in The Avenues, for instance, may want all of those doors rekeyed to one key, and may also want to step up to pick- and bump-resistant cylinders at the same time.

The waterfront adds commercial and marina needs. Boat owners and tenants around King Harbor Marina sometimes need a gate or storage padlock and unit lock serviced after a lost key, and the harbor's salt exposure is hard on hardware. Whether you are near Pacific Coast Highway, Artesia Boulevard, Torrance Boulevard, Aviation Boulevard or Inglewood Avenue, we are a mobile locksmith that comes to you. Call (323) 997-8867 at any hour.

High Security Locks in Redondo Beach — FAQs

What makes a lock "high security"?
High security locks use tighter tolerances, pick- and bump-resistant pin designs, hardened inserts that resist drilling, and often a restricted keyway so keys cannot be casually duplicated. Call (323) 997-8867 and we can explain which features suit your door.
Can you upgrade the old deadbolts on a 1940s Hollywood Riviera home?
Yes. Older exterior deadbolts in coastal homes are often corroded or worn. We can replace them with a Grade-1, drill-resistant cylinder and check that the door and strike are sound enough to support it.
Can all the doors on my North Redondo townhome use one key?
Yes. We can key the front door, garage service door and rear patio door alike so one key operates all of them. This is a popular job after a purchase in areas like The Avenues, El Nido and Golden Hills.
Does salt air affect high security locks?
Coastal air is hard on any hardware, especially exterior locks. We replace corroded parts rather than reusing them and can advise on care to help your hardware last in Redondo Beach conditions.
What is a restricted key?
A restricted key is one that cannot be copied at ordinary key-cutting kiosks. Duplicates generally require authorization, which helps you control who has access. We can explain how extra keys are obtained for your system.
Can you service a marina gate or storage lock at King Harbor?
We can help with padlocks and unit locks at marina and storage locations, including after a lost key. Call (323) 997-8867 with details of the lock and we will discuss what is needed.
Do I need a new door to get better security?
Not necessarily. Often a solid door only needs a better cylinder, deadbolt and a reinforced strike. If the door or frame is the weak point, we will tell you honestly before any work.
Are you open at night and on weekends?
Yes. We are a 24/7 mobile locksmith serving Redondo Beach and the surrounding area. There is no storefront, so call (323) 997-8867 and we will come to you.
