A deadbolt is one of the simplest upgrades you can make to a door, but only if it is fitted properly. Montebello has a wide range of doors, from solid wood entries on 1920s Spanish Revival and Craftsman homes to the hollow-feeling steel and composite doors on post-war stucco tracts and newer hillside houses. Each one needs a slightly different approach, and a deadbolt that is bored crookedly, set too short, or paired with a weak strike plate adds very little security.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and our owner and lead technician, David Shar, built the business on mobile work. We have no storefront. Instead, the work happens at your door: we look at the door, the frame, and the existing hardware, then install or replace the deadbolt on the spot. We are available around the clock, so a door that will not lock tonight does not have to wait until morning.

Whether you are adding a first deadbolt, replacing a worn one, switching from single to double cylinder, or rekeying so old keys stop working, we explain the options plainly and let you decide. We would rather fit the right lock correctly than sell you more than the door can use.

How it works in Montebello

  1. 1

    Tell us about the door

    Call (323) 997-8867 and describe the door: wood, steel, or composite, whether it already has a deadbolt, and what you want changed. If it is a home with older hardware, mention that too, since it affects what we bring.

  2. 2

    We come to you

    Because we are fully mobile and available 24/7, a technician drives to your Montebello address with a range of deadbolts, strikes, and installation tools. There is no shop to visit.

  3. 3

    Inspect the door and frame

    We check the door thickness, the existing bore holes, the condition of the jamb, and whether the latch side has enough solid material. Older doors near the original city core sometimes have worn or previously patched holes we need to work around.

  4. 4

    Install or replace the deadbolt

    We fit the deadbolt so the bolt extends cleanly into the frame, install a proper strike plate with longer screws that reach the framing, and test the throw repeatedly. For a replacement we match the existing bore when possible to avoid unnecessary damage to the door.

  5. 5

    Choose your cylinder type and keys

    We discuss single versus double cylinder. A double cylinder needs a key on both sides, which can matter for doors with glass nearby but is a real consideration for fire exit. We cut and test your keys before we leave.

  6. 6

    Final check and walkthrough

    We operate the lock with you, confirm the door closes without binding, and show you any small adjustments to expect as wood swells or contracts with the seasons.

What affects the price

  • Whether you need a new deadbolt added or an existing one replaced, since adding one can involve drilling a new bore in the door.
  • The grade and brand of the deadbolt you select, from standard residential models to heavier, more pick- and drill-resistant hardware.
  • Single-cylinder versus double-cylinder, and whether keys should match other locks on the property.
  • The condition of the door and frame, including whether the jamb needs reinforcement or a bore needs to be repaired.
  • Door type, such as older solid wood, steel, or a commercial aluminum storefront door, which can call for different hardware.
  • The time of day you call, since after-hours and weekend service is part of our 24/7 availability.

Why Montebello chooses us

  • Fully mobile service: the work is done at your door, with no storefront trip and no need to remove the door.
  • In business since 1987, with owner and lead technician David Shar behind the work.
  • Experience with both older home hardware and modern residential cylinders, which suits Montebello's mix of eras.
  • We reinforce the strike plate and screws as part of a proper install, because the bolt is only as strong as the frame it enters.
  • We tell you plainly when a cheaper fix such as rekeying or adjusting will do the job, rather than pushing a full replacement.
  • Available 24/7, so a broken or missing deadbolt can be handled when it is actually a problem.

Deadbolt Installation across Montebello

Montebello's housing is a patchwork, and that shapes deadbolt work here. Around the older core and in parts of North Montebello you find 1920s to 1950s single-family homes, many Spanish Revival or Craftsman, with solid wood doors that may carry original or older hardware. Those doors can swell in summer heat, and a deadbolt that used to slide smoothly can start to bind. Sometimes the fix is an adjustment or a rekey, and sometimes a new deadbolt fitted carefully into the old door is the better answer.

Across the flats in ZIP code 90640 there are also large tracts of post-war stucco houses, where standard residential cylinders and hollow or steel doors are common. Adding a quality deadbolt and a reinforced strike plate is one of the most practical upgrades for these homes. Up in Montebello Hills, newer hillside homes on the former oil-field slopes often have gated driveways, and we can handle gate hardware and the front-entry deadbolt in the same visit. Neighbors in adjacent Montebello Gardens call us for the same kind of work.

We also see commercial doors. Tenant suites at The Shops at Montebello and storefronts along Washington Blvd often use aluminum-frame doors with different lock hardware, and a failed or broken-key lock there usually needs same-day attention. Whether you are near Grant Rea Park, off Montebello Blvd or Beverly Blvd, or close to the I-5 and I-710 corridors, our mobile technicians come to you.

Deadbolt Installation in Montebello — FAQs

Can you install a deadbolt on a door that does not have one?
Yes. We drill a new bore in the door if needed, fit the bolt and strike plate, and test it before leaving. Call (323) 997-8867 and tell us the door material so we can bring the right tools.
Do you install deadbolts at night or on weekends in Montebello?
Yes. We are available 24/7 and fully mobile, so we come to your door whenever you need us. Call (323) 997-8867 any time.
My older home's deadbolt sticks in the summer. Do I need a new one?
Not always. Heat can swell older wood doors and shift the alignment, so an adjustment or rekey may solve it. If the hardware is worn out, we can replace it. We look at the door first and tell you which makes sense.
What is the difference between single- and double-cylinder deadbolts?
A single cylinder has a key on the outside and a thumb turn inside. A double cylinder needs a key on both sides, which can help when glass is near the lock but can slow exit in an emergency. We help you weigh this for your door.
Can you install a deadbolt at a shop or suite at The Shops at Montebello or on Washington Blvd?
We service commercial doors too, including storefront and suite locks, though mall tenants may need landlord approval first. For same-day help with a broken or failed lock, call (323) 997-8867.
Will a new deadbolt make my door more secure by itself?
It helps, but the frame matters as much as the lock. We install a reinforced strike plate with longer screws so the bolt is anchored into solid framing rather than just the trim.
Can you handle a gate and my front door in one visit in Montebello Hills?
In many cases, yes. If you have a gated driveway and need front-entry deadbolt work, we can look at both during the same trip. Mention it when you call so we plan accordingly.
Do I have to come to your shop to buy a deadbolt?
No. Crenshaw Lock Company is mobile only, with no storefront. We bring the hardware to your Montebello address and install it there.
