A deadbolt is one of the simplest ways to make a door harder to defeat, but only if it is the right lock and it is installed properly. In Lancaster, we regularly see front doors fitted with builder-grade hardware from the tract-home build-out, spring latches with little real resistance, and deadbolts mounted so loosely that a firm kick could spread the door frame. A good installation addresses the lock, the bore, the strike, and the screws that hold it all to the frame.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile, so there is no shop to visit. We bring hardware and tools to your door in Lancaster, whether that is a two-story stucco home in West Lancaster, a bungalow near The BLVD, or an apartment unit that has never had a proper deadbolt.

We install new deadbolts on doors that have none, replace worn or damaged ones, and swap out hardware after a move, a break-in, or a tenant change. We can also talk through single versus double cylinder choices, which matter for doors with glass nearby and for fire-safety reasons. You get a plain explanation of what your door needs, not a sales pitch.

How it works in Lancaster

  1. 1

    Call and describe the door

    Call (323) 997-8867 any hour. Tell us whether the door is wood, steel, or fiberglass, whether it already has a deadbolt, and whether this is a new install or a replacement. A few details up front help us bring the right hardware.

  2. 2

    Assess the door and frame

    On site, we check the door thickness, the existing bore holes, and the condition of the jamb. Lancaster tract homes often have thin, worn strike areas, and a deadbolt is only as strong as what it bolts into.

  3. 3

    Choose cylinder type and hardware

    We go over single-cylinder (thumbturn inside) versus double-cylinder (key both sides) options, along with finish and keying preferences. If a door has glass nearby, we explain the tradeoffs honestly, including egress concerns.

  4. 4

    Install and reinforce

    We bore or adjust the door as needed, mount the deadbolt, and set the strike plate with longer screws that reach the framing behind the jamb. Alignment is checked so the bolt throws fully without binding.

  5. 5

    Test and hand over keys

    We operate the lock repeatedly with the door open and closed, confirm smooth action, and hand over your keys. If you want several doors keyed alike, we can set that up during the same visit.

What affects the price

  • Whether this is a new installation on a door with no bore or a replacement of an existing deadbolt, since new boring takes more work.
  • Single-cylinder versus double-cylinder hardware, and the grade and brand of the deadbolt you select.
  • Door material and condition, as steel, fiberglass, and older wood doors can need different prep or repair.
  • Strike plate and jamb reinforcement, which is worth adding on frames that are cracked, thin, or loosely fastened.
  • The number of doors being done and whether you want them keyed alike, which can streamline the visit.
  • Time of day and the location of the property within the Antelope Valley, since we are mobile and travel to you.

Why Lancaster chooses us

  • Fully mobile and available 24/7, so installs can happen when your schedule allows rather than only during shop hours.
  • In business since 1987, with owner David Shar leading the work and bringing decades of hands-on door and lock experience.
  • We look at the frame and strike, not just the lock, because a strong deadbolt in a weak jamb gives false confidence.
  • Honest guidance on single versus double cylinder, including when a double cylinder is a poor fit.
  • Experience with the housing mix in Lancaster, from builder-grade tract hardware to older downtown bungalows and apartment doors.
  • Clear explanation before we start, with no pressure to buy more than your door actually needs.

Deadbolt Installation across Lancaster

Lancaster's housing is a mix that shapes how we approach deadbolts. Much of the city's single-family stock came from the 1980s through 2000s build-out, with two-story stucco homes in West Lancaster and East Lancaster that often came with basic builder-grade locks. Closer to The BLVD, older bungalows can have aged wood frames that need careful prep, and apartment complexes across the 93534, 93535, and 93536 ZIP codes often need upgrades after tenant turnover.

Rentals and vacant homes add their own needs. Property managers near downtown frequently want deadbolts added or replaced between tenants, and homes that entered the market during the foreclosure era sometimes need new hardware once ownership changes. In Quartz Hill and the Fox Field area, larger lots and rural-edge properties lead many owners to ask for sturdier deadbolts on side and back doors as well as the front.

We travel throughout Lancaster, using routes like CA-14, Sierra Highway, Lancaster Blvd, and the Avenue J, K, and L grid. Whether you are near the Antelope Valley Fairgrounds, the Lancaster Performing Arts Center, or out toward Fox Airfield, call (323) 997-8867 and we will come to you.

Deadbolt Installation in Lancaster — FAQs

Can you install a deadbolt on a door that does not have one?
Yes. If the door is suitable, we bore the needed holes, mount the deadbolt, and set the strike. Call (323) 997-8867 and describe the door so we can bring the right hardware.
What is the difference between single and double cylinder deadbolts?
A single cylinder uses a key outside and a thumbturn inside. A double cylinder needs a key on both sides. Double cylinders can be a concern for fast exit in an emergency, so we discuss which fits your door.
Do you work on rental properties in Lancaster?
Yes. We install and replace deadbolts for landlords and property managers, including between tenants. We can also key several doors alike. Call (323) 997-8867 to arrange it.
Will a new deadbolt actually make my door more secure?
It helps, but the frame matters too. We check the jamb and use a properly secured strike with long screws so the lock is backed by solid framing, not just thin trim.
Do I need to be home during installation?
Someone authorized should be present or arrange access with us. For vacant or managed properties, we can coordinate with the property manager or owner.
Can you replace a deadbolt after a break-in?
Yes. We can replace damaged hardware and repair or reinforce the frame where possible. We are available 24/7 at (323) 997-8867.
Do you have a shop I can visit?
No. We are a fully mobile service, so we come to your location anywhere in Lancaster instead of operating a storefront.
Can you match my existing keys?
Often yes, depending on the brand and keyway. If you want one key for multiple doors, tell us which locks you have and we will advise on the best option.
