Locks in Sierra Madre live hard, quiet lives. Many homes here date to the early 1900s, and the hardware on their doors has often been turned thousands of times, painted over, loosened by decades of seasonal swelling, or swapped piecemeal by a string of owners and tenants. When a deadbolt sticks, a knob wobbles, or you simply do not know who still holds a key, replacing the lock is often the cleanest answer.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, under owner and lead technician David Shar. We are fully mobile, with no storefront to visit. We bring the tools and a range of hardware to your door in Sierra Madre, whether that is a Craftsman cottage near the village core, a hillside house in the canyon, or a small shop near Kersting Court.

Replacement is not always the right call, and we will tell you so. A well-made old mortise lock can often be rekeyed or carefully retrofitted instead, which preserves the character of a century-old door. When replacement does make sense, we help you choose hardware that fits the door you actually have, rather than forcing a one-size-fits-all fix.

How it works in Sierra Madre

  1. 1

    Tell us what is wrong and where

    Call (323) 997-8867 any hour and describe the door, the lock and the problem. Is it a sticking deadbolt, a broken handle, a lost key, or a lock you simply want upgraded? We note the address, including whether it is on a narrow canyon lane, so we arrive prepared.

  2. 2

    Inspect the door and existing hardware

    On site, we look at the lock, the strike, the bore holes and the condition of the door itself. Older Sierra Madre doors can be non-standard in thickness or preparation, and some carry mortise lock bodies, so we check what will fit before anything is removed.

  3. 3

    Decide between replacing, rekeying or retrofitting

    If the existing lock is sound, rekeying may solve a key-control problem for less effort. If it is worn, damaged or mismatched, we recommend replacement. For original skeleton-key mortise locks, we discuss careful retrofits that respect the door.

  4. 4

    Remove the old lock and install the new one

    We remove the old hardware with care to protect the door and trim, then fit the new lock, aligning the latch and strike so it throws smoothly. Where a door has been repainted many times, we take extra care that the finish is not chipped more than necessary.

  5. 5

    Key, test and hand over

    We key the new lock to your needs, including matching multiple doors to one key where you want that convenience. Then we test every key, the latch and the deadbolt several times with the door open and closed, and show you how everything works before we leave.

What affects the price

  • The type of lock: a basic knob, a standard deadbolt, a higher-security cylinder or a mortise set all involve different hardware and labor.
  • Whether the door is standard or non-standard. Century-old doors may need additional fitting, adjustment or modified preparation.
  • How many doors you want replaced and whether you want them all keyed alike to a single key.
  • The condition of the strike, latch area and door edge, which can affect how much adjustment is needed for a clean fit.
  • Time and access: after-hours calls, and locations like canyon lanes where tools must be carried up from where the van parks, can affect the scope of the visit.
  • Whether rekeying or a retrofit can solve the problem instead of full replacement, which changes the hardware involved.

Why Sierra Madre chooses us

  • Fully mobile since 1987, so the work happens at your door in Sierra Madre with no shop trip and no storefront to visit.
  • Comfortable with old hardware. We can evaluate original skeleton-key mortise locks and recommend retrofitting or rekeying when that suits a historic door better than replacement.
  • Honest recommendations. If your lock only needs rekeying or adjustment, we will say so rather than sell you new hardware.
  • Prepared for tight access. We plan for narrow, steep canyon lanes where the van parks below and tools are carried up on foot.
  • Available 24/7, including nights and weekends, for broken locks that cannot wait.
  • Owner-led experience. David Shar leads the work, backed by decades of residential and small-business lock work across the region.

Lock Replacement across Sierra Madre

Sierra Madre is a small, walkable foothill town, and its housing tells the story of our work. Around the village core and downtown, you will find early-1900s Craftsman cottages, Victorians and bungalows, many a short stroll from the famous wisteria vine. After a tenant turnover on a cottage in 91024, we are often asked to replace worn exterior locks or rekey every door so that old keys no longer matter.

Sierra Madre Canyon is a different world. Narrow, steep lanes wind past old cabins and hillside homes, many with original skeleton-key mortise locks and non-standard doors. In 91025 and the canyon area, we usually park the van below and carry tools up, and we plan hardware choices carefully so the replacement fits a door that was never built to modern dimensions.

Downtown, the small-shop storefronts around Kersting Court have their own needs, from replacing a tired cylinder on a cafe door to securing a shop after staff changes. We reach Sierra Madre by way of Sierra Madre Blvd, Baldwin Ave, Michillinda Ave or the nearby I-210 Foothill Fwy, and we serve homes near Bailey Canyon Wilderness Park and the Mount Wilson Trail as well.

Lock Replacement in Sierra Madre — FAQs

Do you offer lock replacement in Sierra Madre at night?
Yes. We are available 24/7 and fully mobile, so call (323) 997-8867 any time and we will talk through your situation and get to work.
Can you replace the original skeleton-key lock on my canyon cabin?
Often we can, but we may suggest an alternative first. Many original mortise locks can be rekeyed or carefully retrofitted, which keeps the look of a century-old door. We inspect the lock and door and recommend what fits best.
Should I replace my locks or just rekey them?
If the lock works well and you only worry about who has keys, rekeying may be enough. If the lock is worn, damaged, loose or outdated, replacement is usually the better choice. We will tell you which applies after looking at it.
I just moved into a Craftsman cottage. What should I do?
Changing or rekeying every exterior lock is a sensible first step, since you cannot know how many old keys exist. Call (323) 997-8867 and we can handle all doors in one visit and key them alike if you wish.
Will new locks fit my old door?
Usually, yes, but older doors can be non-standard in thickness or preparation. We check the door before choosing hardware and make the adjustments needed for a clean fit.
Can you help a shop near Kersting Court?
Yes. We replace and rekey cylinders for small businesses, including cafes and shops, and can help after a lockout or staff change. Call (323) 997-8867 to describe your door.
How is lock replacement priced?
Price depends on the lock type, the condition and style of the door, the number of doors, keying preferences and the time and access involved. We describe the factors when you call and confirm the scope on site.
Do I have to come to a shop?
No. We are mobile only, with no storefront. We bring the tools and hardware to your door anywhere in Sierra Madre.
