A deadbolt is one of the least expensive ways to make a door meaningfully harder to defeat, but only if it is fitted properly. In San Gabriel the doors vary enormously. Some are solid-core mid-century slabs, some are hollow doors that have been patched over the decades, and some are century-old divided-light wood doors that were never designed with a modern bolt in mind. A good installation starts with reading the door, not just grabbing a box off a shelf.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar and our technicians come to you. We are fully mobile, so there is no storefront to visit. We bring hardware, drilling tools and strike reinforcement to your door, and we work around the clock, including nights, weekends and holidays.

Whether you are adding a first deadbolt to a bungalow near the Mission, upgrading a worn lock after moving into an apartment off Las Tunas Drive, or replacing a failed storefront bolt on a Valley Boulevard restaurant, the goal is the same: a bolt that throws smoothly, seats deeply into solid framing, and works with the keys you actually want to carry.

How it works in San Gabriel

  1. 1

    Talk through the door and the need

    When you call (323) 997-8867 we ask about the door material, whether a bolt already exists, and what worries you. We also ask if anyone needs to exit quickly, which matters for choosing between single- and double-cylinder.

  2. 2

    Inspect the door and frame on site

    At the property we check door thickness, material, condition of the edge and the jamb. A strong bolt in a weak frame gains little, so we look for split wood, loose hinges and a shallow strike plate before anything is drilled.

  3. 3

    Choose single or double cylinder

    A single-cylinder bolt turns by thumbturn inside. A double-cylinder needs a key on both sides, which can suit doors with glass nearby but affects fast exit during a fire. We explain the tradeoff plainly and respect local safety considerations.

  4. 4

    Prepare the door and install

    We mark and bore the door where needed, or fit the new bolt into an existing bore when replacing. We take care with older wood doors to avoid splintering and to keep the finish as intact as possible.

  5. 5

    Reinforce the strike and frame

    We fit a strike plate with long screws that reach the framing behind the jamb, which is where most forced-entry failures happen. Where the frame is tired, we discuss additional reinforcement.

  6. 6

    Test, key and hand over

    We cycle the bolt repeatedly with the door open and closed, check alignment, and hand over your keys. If you have several doors, we can key them alike so you carry fewer keys.

What affects the price

  • Whether this is a new installation requiring a bored hole or a straight replacement of an existing deadbolt.
  • The grade and brand of the hardware you choose, from standard residential to heavier-duty commercial-style bolts.
  • Door material and condition, since solid wood, metal, and older divided-light doors need different preparation.
  • Frame and strike reinforcement needed to make the bolt actually hold up.
  • The number of doors and whether you want them keyed alike or rekeyed to an existing key.
  • Time of day and urgency, since after-hours and emergency calls involve different scheduling than planned work.

Why San Gabriel chooses us

  • Fully mobile service: we come to your door with hardware on the truck, so there is no shop trip.
  • In business since 1987, with long experience on both older wood doors and modern slabs.
  • Available 24/7, which matters when a lock fails or a break-in leaves a door unsecured at night.
  • We look at the frame and strike, not just the bolt, because that is where installs often fall short.
  • Careful handling of historic doors near the Mission, aiming to preserve original character where we can.
  • Residential and commercial experience, so a home bolt and a restaurant storefront get appropriate hardware.

Deadbolt Installation across San Gabriel

San Gabriel mixes eras more than most cities. Around the Mission District and the streets near Mission San Gabriel Arcangel, founded in 1771, you find Craftsman and Spanish Colonial Revival bungalows from roughly the 1900s to the 1920s. Many have original mortise locks and divided-light wood doors. On these, adding a deadbolt takes a gentle hand: narrow stiles, glass close to the lock and old finishes all call for careful drilling and sometimes a different approach than a standard bore.

Away from the historic core, especially along Las Tunas Drive and Del Mar Avenue, you see mid-century single-family homes and apartment buildings. Here the common jobs are first-time deadbolts, replacing worn bolts, and rekeying after tenant turnover in 91776 and 91775. Owners of multi-unit buildings often want matched hardware and a clear key plan across doors.

The Golden Mile along Valley Boulevard and the retail stretch of San Gabriel Boulevard bring commercial needs, where aluminum storefront doors and roll gates call for different hardware than a house. If a restaurant near 91776 or 91778 has a failed deadbolt or a broken key, we can come out around the clock. Homes near Vincent Lugo Park and just off I-10 get the same attention. Call (323) 997-8867 from anywhere in San Gabriel.

Deadbolt Installation in San Gabriel — FAQs

Can you install a deadbolt on an old wood door near the Mission?
Often yes. We inspect the door first, since narrow stiles and glass panels limit options. We choose hardware and a drilling approach that protects the wood. Call (323) 997-8867 and describe the door.
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, which can help near glass but slows exit in an emergency. We explain both before you decide.
Do you offer deadbolt installation at night or on weekends?
Yes. Crenshaw Lock Company is available 24/7 and fully mobile. Call (323) 997-8867 any time and we will talk through your situation.
Can you replace a deadbolt on a Valley Boulevard restaurant?
Yes. We handle commercial storefront deadbolts, including failed bolts and broken-key emergencies. Door type affects what hardware fits, so tell us whether it is aluminum, glass or wood when you call.
Will a new deadbolt work with my existing key?
In many cases we can key a new bolt to match your current key, or key several doors alike. It depends on the brand and keyway of your existing lock.
Does a deadbolt make my door secure on its own?
Not entirely. The strike plate, screws, jamb and hinges matter just as much. We reinforce the strike and check the frame so the bolt can do its job.
Can you do several apartment doors at once?
Yes. Multi-unit owners often combine new deadbolts with rekeying after tenant turnover. We can plan a consistent key arrangement across the building.
Do I need to visit your shop?
No. We are mobile only and come to your home or business in San Gabriel, so there is no storefront to visit.
