A deadbolt is the single most useful upgrade you can make to an entry door, but only if it is fitted correctly. A strong bolt in a poorly bored door, or one with a short strike plate screwed into soft trim, gives much less protection than it appears to. In a city as varied as Long Beach, the door in front of us could be a 1920s Craftsman door with original mortise hardware, a salt-weathered canal-house entry, or a hollow-core apartment door in a dense building near Alamitos Beach.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and the business is owned and led by David Shar. We are 100 percent mobile. There is no storefront to drive to; we come to your home, apartment, or condo and do the work on site. That means we can look at your actual door, frame, and neighbors' sightlines before recommending anything.

Whether you are adding a first deadbolt, replacing a worn or sticky one, or switching to a different cylinder style after a move, we explain the options plainly. We will tell you when a simple single-cylinder is the right call, when a double-cylinder makes sense, and when the better fix is reinforcing the door or frame instead of just adding more hardware.

How it works in Long Beach

  1. 1

    Talk through the door and your goal

    Call (323) 997-8867 and tell us what you have: door material, existing lock, and whether you want a new deadbolt added or an old one replaced. We ask about the building too, since an HOA condo, a rental, and a historic home each come with different constraints.

  2. 2

    Inspect the door and frame on site

    When we arrive we check door thickness, material, and condition, plus the frame and strike area. We look for rot, prior bad drilling, warped doors, or a thin jamb that would undermine the new bolt, and we tell you what we find before we start.

  3. 3

    Choose cylinder type and hardware

    We go over single-cylinder (thumb turn inside) versus double-cylinder (key on both sides), and what each means for convenience, glass-adjacent doors, and safe exit. We also talk about finish and grade, including corrosion-resistant options for homes near the water.

  4. 4

    Install and reinforce

    We bore or reuse the existing holes as appropriate, set the bolt, and fit a strike plate with screws long enough to reach the framing, not just the trim. On weak frames we recommend reinforcement so the bolt has something solid to bite into.

  5. 5

    Test, key, and hand over

    We operate the lock repeatedly with the door open and closed, check alignment, and confirm smooth throw. You get your keys, and if you want the new deadbolt keyed to match other locks, we can discuss that during the visit.

What affects the price

  • Whether you are adding a brand-new deadbolt or replacing an existing one, since a new install may need additional boring and prep.
  • The condition and material of the door and frame, including whether reinforcement or repair is needed for the bolt to be effective.
  • The hardware you choose: grade, finish, single versus double cylinder, and whether you want corrosion-resistant or higher-security cylinders.
  • How many doors are being done and whether they should be keyed alike to work with a single key.
  • Time of day and location, since 24/7 mobile service at night or on weekends is handled differently than a scheduled daytime visit.
  • Special situations such as historic doors that need careful, minimally invasive work, or buildings with HOA or landlord requirements.

Why Long Beach chooses us

  • Operating since 1987, so we have seen how deadbolts fail on everything from old wood doors to modern steel and fiberglass.
  • Fully mobile and available 24/7, which suits renters and owners who need a door secured after a break-in attempt, a move, or a lost key.
  • We treat the strike plate and frame as part of the job, not an afterthought, because that is where many installs fall short.
  • Honest recommendations: if your door is the real weakness, we say so rather than selling you hardware that will not help.
  • Comfortable with period homes, so we can discuss options that respect original character instead of defaulting to heavy drilling.
  • Owner-led by David Shar, with clear explanations of single versus double cylinder tradeoffs, including safe-exit considerations.

Deadbolt Installation across Long Beach

Long Beach is a big, varied coastal city, and deadbolt needs change block by block. In California Heights, a designated historic district, and in Belmont Heights, many 1920s Craftsman and Spanish Colonial homes still have original doors and mortise-style hardware. Adding a deadbolt there takes care: we look at door thickness, existing mortises, and whether a modest retrofit will protect the door without gutting its character.

Near the water, in Naples and Belmont Shore, salt air is hard on exterior hardware. A deadbolt on a canal-home or bungalow entry may seize or corrode faster than you would expect, so we talk about corrosion-resistant finishes and sensible maintenance when replacing one. Further inland, in dense apartment areas around Alamitos Beach and Wrigley, the common issue is thin or worn doors and frames, where proper strike reinforcement matters as much as the bolt itself. Downtown condos and lofts often have HOA rules on exterior hardware, so check your building's requirements first and we will work within them.

We serve Long Beach ZIP codes including 90802, 90803, 90804, 90807, 90814, and 90815, and the rest of the city from the Port-side west end to the neighborhoods near CSULB and El Dorado Regional Park. Whether you are near Ocean Blvd, Atlantic Ave, or just off the I-710 or I-405, call (323) 997-8867 and we will come to you.

Deadbolt Installation in Long Beach — FAQs

Can you install a deadbolt on a door that does not have one?
Usually yes. We check the thickness and material of the door and the strength of the frame, then bore the needed holes and fit a proper strike plate. Call (323) 997-8867 to describe your door and we can tell you what to expect.
Should I choose a single-cylinder or double-cylinder deadbolt?
Single-cylinder has a thumb turn inside and is easier and safer to exit in an emergency. Double-cylinder needs a key on both sides and is sometimes used on doors with nearby glass, though it raises safe-exit concerns. We explain the tradeoffs for your specific door.
My home in California Heights has an original mortise lock. Can you add a deadbolt?
Often we can repair, retrofit, or add security in a way that respects the original door. We look at the door's thickness and existing hardware first and discuss options that avoid unnecessary damage to period features.
Does salt air near Naples or Belmont Shore affect deadbolts?
Yes, coastal moisture and salt can corrode cylinders and make keys stick or seize. When replacing a deadbolt for a waterfront home, we can discuss corrosion-resistant finishes and lubrication. Call (323) 997-8867 if yours is already sticking.
Do you work on apartments and condos downtown?
Yes, though many buildings have HOA or landlord rules on exterior hardware. Check with your property manager first, and we will work within those requirements and discuss which deadbolts suit your door.
Will a new deadbolt help if my door frame is weak?
Only partly. A strong bolt needs a solid frame and a properly anchored strike plate. If the jamb is split or thin, we recommend reinforcement so the deadbolt actually does its job.
Are you available at night or on weekends?
Yes. We are a 24/7 mobile locksmith, so if you need a door secured after a break-in, a lockout, or a late move-in, call (323) 997-8867 and we will help.
Do I need to visit a shop to choose my deadbolt?
No. Crenshaw Lock Company is mobile only, with no storefront. We bring hardware options to you and install on site after looking at your door.
