A lock that sticks, spins loosely or won't throw its bolt rarely fixes itself, and in San Marino the cause is often the age of the hardware. Many homes here date from the 1920s and 1930s, with solid-wood doors, heavy mortise lock bodies and brass trim that has been turned thousands of times. Wear, seasonal wood movement and years of paint or polish can all throw a lock out of alignment.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar has spent decades working on everything from vintage mortise sets to modern high-security deadbolts. We are fully mobile. There is no storefront to visit; we bring tools and parts to your property, whether it is the front door, a side entry, a garden gate or a pool house.

Repair is often the better first choice, especially on period hardware worth keeping. We look at what is actually failing, whether a worn cylinder, a bent latch, a loose mounting or a door that has shifted, and explain the options plainly. If a part cannot be repaired sensibly, we say so and talk through replacement, ideally in a finish that suits the house.

How it works in San Marino

  1. 1

    Call and describe the symptoms

    Phone (323) 997-8867 at any hour. Tell us which door is affected and what the lock does: sticks, jams, turns freely without engaging, or will not latch. Details such as whether the key works smoothly help us bring the right parts.

  2. 2

    We come to you

    Because we are fully mobile and available 24/7, we travel to your San Marino home with tools and common components for mortise sets, deadbolts, latches and strikes. Nothing requires a trip to a shop.

  3. 3

    Diagnose the real cause

    We test the key, the cylinder, the latch and the door alignment. Many lock complaints come from a misaligned strike plate or a swollen door rather than a bad lock, so we check the whole assembly before touching anything.

  4. 4

    Repair, adjust or service

    We tighten, realign, clean, lubricate or replace worn internal parts as needed. On original brass or bronze hardware we work carefully to preserve the finish and keep the lock looking as the house intended.

  5. 5

    Test and review options

    We cycle the lock repeatedly with the door open and closed, confirm every key works, and walk through anything worth considering next, such as a high-security cylinder or rekeying to a single key.

What affects the price

  • The type of lock involved: a standard deadbolt, a modern smart lock and an original mortise set each need different time and parts.
  • Whether the fault is an adjustment, such as alignment or a loose mounting, or requires replacing worn internal components.
  • Availability and fit of parts for older or specialty hardware, including vintage mortise bodies and decorative trim.
  • The number of doors or gates being repaired during the same visit.
  • Whether you want add-ons at the same time, like rekeying, a higher-security cylinder or matching keys across all locks.
  • The time of day and urgency of the call, since we are available around the clock.

Why San Marino chooses us

  • Experience with period hardware: we are comfortable servicing original mortise locks on 1920s and 1930s revival homes rather than defaulting to replacement.
  • Fully mobile service, so repairs happen at your door without you traveling or leaving the property unsecured.
  • Operating since 1987 under owner David Shar, with long familiarity across Los Angeles County homes.
  • Honest diagnosis: we tell you when a simple adjustment will do and when a part truly needs replacing.
  • Repair paired with security: we can add a high-security cylinder or rekey during the same visit, keeping the original look.
  • 24/7 availability for locks that fail at inconvenient hours.

Lock Repair across San Marino

San Marino's character comes from its estates, and its locks reflect that. Around the Huntington Library district, many homes are Spanish Colonial, Tudor and Georgian revival houses with original solid-wood doors and heavy brass mortise hardware. A typical job here is servicing a stiff mortise lock, preserving the vintage trim, and fitting a high-security cylinder so the door looks unchanged but works better.

In the Lacy Park neighborhood, large lots mean more entry points: front doors, service doors, side gates and garden gates, each with its own lock and its own wear. We often see owners who want everything working smoothly and, after a staff change or a lost key, re-pinned to a single key. Properties in ZIP code 91108 along Huntington Drive, Sierra Madre Boulevard, San Gabriel Boulevard, Del Mar Avenue and Los Robles Avenue are all within our service area.

The Mission District along Huntington Drive also has modest neighborhood commercial doors that see heavier daily use. Whether you are near El Molino Viejo, Crowell Public Library or tucked into a quiet residential street, call (323) 997-8867 and we will come to you.

Lock Repair in San Marino — FAQs

Can you repair original mortise locks on older San Marino homes?
Yes. Mortise hardware is common in the city's 1920s and 1930s homes, and we service it regularly. We aim to repair and preserve the original brass or bronze rather than replace it. Call (323) 997-8867 to describe your lock.
Why does my deadbolt stick or feel hard to turn?
Common causes include a misaligned strike plate, a door that has shifted with the seasons, a worn cylinder or dirt in the mechanism. We check each one so we fix the actual cause rather than guess.
Is it better to repair or replace a lock?
Repair is often enough, especially for quality or vintage hardware. If a lock is badly worn or no longer secure, we will explain why replacement makes sense and what options fit your door.
Do you offer lock repair at night or on weekends?
Yes. We are available 24/7 and fully mobile. Call (323) 997-8867 at any hour and we will talk through the problem and get to you.
Can you upgrade security while repairing a lock?
Yes. We can fit a high-security cylinder, add a residential safe-grade deadbolt or rekey the lock during the same visit, while keeping the existing look of period hardware where possible.
Can you fix locks on side gates and garden gates?
Yes. Many San Marino properties have multiple gates on large lots. We can repair or rekey gate locks and match them to the same key as your house doors.
Do I need to visit your shop?
No. We are mobile only and have no storefront. We bring everything to your property.
What if I lost a key and my lock also acts up?
We can repair the lock and rekey it so lost keys no longer work, often re-pinning several doors to one key. Call (323) 997-8867 to arrange it.
