A deadbolt is one of the simplest upgrades you can make to a door, and in Lomita it is often one of the most worthwhile. Much of the city is made up of modest single-family homes built between the 1940s and 1960s, and many of them still carry the hardware that came with the house or a replacement from decades ago. Worn latches, loose cylinders and bolts that barely reach the frame are common on doors of that age. A properly fitted deadbolt gives the door real resistance where a spring latch gives almost none.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no storefront in Lomita to drop by. We come to your front door, back door, garage side door or apartment entry with the tools and hardware needed to do the job on the spot, whether that is a first-time installation or a swap for a tired old deadbolt. Owner and lead technician David Shar built the business on straightforward, careful lock work.

Deadbolts are not one-size-fits-all. A single-cylinder deadbolt, with a key outside and a thumbturn inside, suits most entry doors. A double-cylinder, keyed on both sides, can make sense on doors with glass nearby, though it has fire-safety tradeoffs we will explain honestly. We help you choose based on your door, your household and your local codes, and we install it so it lines up cleanly and works smoothly.

How it works in Lomita

  1. 1

    Call and describe your door

    Call (323) 997-8867 any hour. Tell us whether the door is wood, metal or fiberglass, whether you want a new deadbolt or a replacement, and whether you want other locks keyed to match. That lets us arrive with suitable hardware.

  2. 2

    Inspect the door and frame

    We check the door thickness, the existing bore holes, the edge, and the strike area of the frame. On older post-war doors, wear or past repairs can affect how a deadbolt should be fitted, and we point out anything that needs attention.

  3. 3

    Choose the right type and grade

    We go over single- versus double-cylinder options, finishes, and hardware quality. If a window sits close to the door, or the door is used as an exit by children or older family members, we talk through which choice is safest.

  4. 4

    Install and reinforce

    We fit the deadbolt, drill or adjust the bore if needed, and set the strike plate so the bolt throws fully into the frame. Where the frame is weak, we can recommend a reinforced strike or longer screws that anchor into the framing.

  5. 5

    Key matching if requested

    If you want the front door, back door and detached garage on one key, we can set the new hardware to match where compatible. Apartment managers can have units keyed according to their own system.

  6. 6

    Test and hand over

    We cycle the bolt several times with the door open and closed, confirm the keys work smoothly from both sides, and hand you the keys. You see the finished work before we pack up.

What affects the price

  • Whether you need a new installation on a bare door or a replacement of an existing deadbolt, since drilling and fitting new bores takes more work.
  • Single-cylinder versus double-cylinder hardware, and the grade and brand of the deadbolt you choose.
  • Door material and condition, including whether older wood doors need bore repair or a metal door needs special handling.
  • Frame and strike reinforcement, such as upgraded strike plates or longer screws, if the frame is worn or weak.
  • How many doors are being done and whether you want them keyed alike, which can streamline the work across several locks.
  • Time of day and urgency, since after-hours and same-night calls are handled differently from scheduled work.

Why Lomita chooses us

  • Fully mobile service: we work at your door in Lomita, and there is no storefront to visit.
  • In business since 1987, with owner David Shar personally involved in the work.
  • Available 24/7, so a broken or missing deadbolt after a break-in attempt or a move-in can be handled outside business hours.
  • Honest recommendations on single- versus double-cylinder choices, including the safety tradeoffs, rather than pushing the most expensive option.
  • Experience with older post-war doors and frames, where careful fitting and strike reinforcement matter as much as the lock itself.
  • Keyed-alike options that suit homeowners with detached garages and managers with several units.

Deadbolt Installation across Lomita

Lomita is a compact city of roughly two square miles, incorporated in 1964, and its housing shapes what we do. Around the Narbonne Avenue corridor and in the Harbor Hills area, you find many 1950s single-family homes on smaller lots. Exterior deadbolts on these houses have often been in service for decades. A typical call is a homeowner who wants worn front and back deadbolts replaced and the detached garage keyed to match, so one key covers the property.

Closer to Lomita Boulevard and the City Center, there are small apartment buildings and condos from the 1960s through the 1980s. Managers there often need deadbolts added or replaced between tenants, sometimes with rekeying and a laundry-room lock handled in the same visit. Residents across ZIP code 90717 also tell us they want a stronger deadbolt before travelling, particularly those who use Pacific Coast Highway or Western Avenue for long commutes.

Because Lomita sits at the gateway to the Palos Verdes Peninsula, we also hear from people with a foot in both worlds, such as those with a gated-community address uphill and a rental or family home down here. Whether you are near Lomita Park, the Lomita Railroad Museum, or tucked into a quiet side street off Narbonne, we come to you.

Deadbolt Installation in Lomita — FAQs

Can you install a deadbolt on a door that has never had one?
Yes. We drill the proper bore holes, install the bolt and strike, and test the result. Call (323) 997-8867 and describe the door so we can bring suitable hardware.
Should I choose a single- or double-cylinder deadbolt?
Single-cylinder suits most doors and lets you exit quickly with the thumbturn. Double-cylinder can help where glass is near the lock, but it needs a key to exit, which is a fire-safety concern. We will go through it with you.
My Lomita home is from the 1950s. Will a new deadbolt fit the old door?
Usually yes. Older doors sometimes have worn or oversized holes or soft wood around the edge, so we inspect first and make adjustments or reinforcement as needed.
Can the deadbolts on my house and detached garage use one key?
In most cases we can set compatible hardware to the same key. It is a common request in Lomita, where many homes have a separate garage. Call (323) 997-8867 to discuss your setup.
Do you handle apartment units and property managers?
Yes. We can add or replace deadbolts and rekey multiple units, and we can also address shared items like laundry-room locks during the same visit.
Do you have a shop I can visit in Lomita?
No. Crenshaw Lock Company is fully mobile, so we come to your door instead. That keeps the work at your property and lets us test the lock in place.
Can you install a deadbolt at night or on weekends?
We are available 24/7. If your deadbolt failed or your door feels insecure after hours, call (323) 997-8867 and we will help you plan next steps.
Does a new deadbolt make the frame stronger too?
The deadbolt only works as well as the frame holding it. We can recommend a reinforced strike plate and longer screws so the bolt is anchored into the framing and not just the trim.
