Installing a lock sounds simple until you meet the door. In Sierra Madre, the door might be a century-old Craftsman front door with a deep mortise pocket, a hillside cabin door in Sierra Madre Canyon that has never been drilled for a modern bore, or a freshly hung shop door near Kersting Court that needs a proper commercial-grade cylinder. Getting the lock to fit, latch cleanly, and hold up for years takes care and the right hardware.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile, with no storefront to visit. We come to you, around the clock, with the tools to bore, chisel, fit, and test a new lock on site.

Lock installation is different from replacement or rekeying. You are adding hardware where none existed, or putting it on a door that is new, repaired, or modified. That means checking door thickness, edge condition, frame alignment, and strike placement before any drilling happens. We would rather spend a few extra minutes measuring than leave you with a lock that binds in a damp winter or loosens over time.

How it works in Sierra Madre

  1. 1

    Talk through the door and the goal

    When you call (323) 997-8867, we ask what kind of door it is, what material it is made of, and what you want the lock to do. A front entry, a back door, a side gate, a studio, and a shop each call for different hardware. Knowing this up front helps us arrive with the right options.

  2. 2

    Inspect the door and frame on site

    We check door thickness, edge condition, hinge side, and how well the door sits in its frame. Older Sierra Madre doors often have swelled, painted-over, or slightly out-of-square frames, and those details decide what installs cleanly and what needs adjustment first.

  3. 3

    Choose hardware that fits

    We go over deadbolts, knobs, levers, and mortise options with you, covering security grade, finish, and whether you want keyed-alike locks across several doors. On period homes we look for hardware that suits the look of the house without compromising security.

  4. 4

    Prepare the door and install

    We mark, bore, and chisel for the latch and bolt, fit the strike plate, and set the cylinder. Where the wood is thin or aged, we reinforce so the lock is not just attached to the door but properly supported by it.

  5. 5

    Test, adjust, and hand over keys

    We cycle the lock repeatedly with the door open and closed, make sure the bolt throws fully into the strike, and adjust any rubbing. You get your keys and a quick walkthrough, and we can key additional doors to match.

What affects the price

  • The type of lock: a basic deadbolt, a high-security cylinder, a smart lock, and a mortise set all involve different hardware and labor.
  • The condition of the door: solid, hollow, or aged wood affects whether the door needs reinforcement or extra preparation before the lock goes in.
  • Whether the door is already bored: a pre-drilled door is quicker than one that needs new holes cut and a latch pocket chiseled.
  • The number of doors and whether you want them keyed alike, which affects both hardware choices and time on site.
  • Access and working conditions, such as a long carry up a steep canyon lane or an unusual door that takes extra fitting.
  • The time of day: we are available 24/7, and after-hours work can be priced differently from daytime scheduling.

Why Sierra Madre chooses us

  • Fully mobile and available 24/7, so installation can happen when it suits you, not only during store hours.
  • In business since 1987, with experience on old, irregular, and non-standard doors that modern kits are not made for.
  • Owner-led by David Shar, so the standards on your job are set by someone with long hands-on experience.
  • We fit hardware to the door rather than forcing the door to fit the hardware, which matters on historic Craftsman and canyon-cabin doors.
  • We test every lock before leaving and adjust until it throws smoothly, so you are not left with a stiff or misaligned bolt.
  • We are straightforward about what a door can and cannot support, and we will tell you if a door needs repair before a lock makes sense.

Lock Installation across Sierra Madre

Sierra Madre is a compact foothill town, and its housing tells you a lot about what a lock installation here involves. Around the village core you find early-1900s Craftsman cottages, Victorians, and bungalows, many with original doors that have been painted, planed, and rehung over the decades. Fitting a modern deadbolt into one of these takes patience: the wood may be thicker or thinner than modern standards, and the frames have settled with age. In ZIP code 91024, near Sierra Madre Blvd and Baldwin Ave, a new lock often means careful chiseling and strike work to keep the door looking right.

Sierra Madre Canyon is its own world, with narrow, steep lanes of old cabins and hillside homes. Many have original skeleton-key mortise locks and non-standard doors. On a job like this, access can be the hardest part, since the van may have to park below and we carry tools up on foot. We plan for that, bringing a focused kit so we are not walking back down for a missing part. Where an old mortise lock stays, we can discuss adding a modern deadbolt alongside it so the character of the door is kept and the security is improved.

Downtown, the small shops around Kersting Court have their own needs: new tenants, new doors, and back-room or storefront locks that must be reliable and easy for staff to use. Whether you are in 91024 or 91025 near Michillinda Ave and Sierra Madre Villa Ave, we come to you at any hour, from a morning before opening to a late night after closing. It is a small town, and we treat the work like it.

Lock Installation in Sierra Madre — FAQs

Can you install a lock on a door that has never had one?
Yes. We measure the door, bore the holes for the lock and latch, chisel the pocket, and fit the strike plate. Call (323) 997-8867 and describe the door so we can bring suitable hardware.
Do you install locks on old Craftsman and Victorian doors in Sierra Madre?
Yes. Older doors often have unusual thickness, aged wood, or out-of-square frames. We fit hardware carefully and can reinforce the door where needed so the new lock is secure and the door still looks right.
Can you add a deadbolt to a Sierra Madre Canyon cabin with a skeleton-key lock?
Often yes. Depending on the door, we can add a modern deadbolt alongside the original lock to keep the look while improving security. Parking may be below the lane, and we carry tools up. Call (323) 997-8867 to discuss.
Are you available at night or on weekends?
Yes. We are a 24/7 mobile locksmith, so you can call any hour. There is no storefront to visit, because we come to your home or business.
Can you key several new locks to the same key?
Yes. If you are installing locks on multiple doors, we can key them alike so one key works throughout, which is helpful for homes and small shops.
I run a small shop near Kersting Court. Can you install commercial-ready locks?
Yes. We can install locks suited to storefront and back-room doors and talk through options for staff access. Schedule at a time that works for your hours by calling (323) 997-8867.
What is the difference between lock installation and rekeying?
Installation adds new hardware to a door, either where none existed or on a new door. Rekeying changes the internal pins of an existing lock so old keys no longer work. We can do both on the same visit.
How do I know which lock is right for my door?
It depends on door material, thickness, how the door is used, and your security needs. We inspect the door on site and recommend options, so you can choose with clear information.
