Altadena is not an ordinary housing market right now. Many of its homes are 1910s to 1940s Craftsman bungalows, Spanish Colonial houses and mid-century builds, with a great deal of that character concentrated in the Janes Village tract. After the January 2025 Eaton Fire, the lock work here has changed: some owners are dealing with hardware on surviving homes that has been fouled by smoke and ash, while others are building from the ground up and need every door keyed from scratch.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has seen how different a lock job can be from one house to the next. We are fully mobile, so there is no shop to visit. We bring tools, cylinders, and hardware to your property, whether that is an older bungalow, a hillside lot, or a jobsite with only framing and a temporary door.

Residential locksmith work covers a lot of ground: rekeying after a purchase or a lost key, replacing worn or damaged locksets, repairing deadbolts that stick or spin, upgrading to stronger hardware, and building simple master-key systems. This page explains how we approach that work in Altadena, what affects the cost, and what to expect when you call.

How it works in Altadena

  1. 1

    You call and describe the situation

    Call (323) 997-8867 any hour. Tell us what the lock is doing, how old the house is, and whether it is a surviving home, a rebuild, or a recent purchase. That helps us bring the right cylinders, deadbolts and parts instead of guessing on the doorstep.

  2. 2

    We come to the property

    Because we are fully mobile, a technician travels to your home or jobsite with the tools and stock for the job. There is no storefront, so everything you need is handled at your door.

  3. 3

    Assessment of every lock involved

    We check each entry point: front and back doors, side-yard gates, garage entries, and any outbuildings. On older Altadena homes we look at whether the original mortise or cylinder hardware can be saved, and on fire-exposed homes we check for soot, corrosion and seized internal parts.

  4. 4

    Clear options before work begins

    We explain what we recommend and what the alternatives are, such as freeing and rekeying a seized lock versus replacing it. You decide before we start, and we do not push upgrades you do not need.

  5. 5

    Rekey, repair, replace or install

    We do the work on site: rekeying cylinders, installing new locksets, fitting deadbolts, or setting up a master-key system that lets one key open several doors while each door stays individually keyed.

  6. 6

    Testing and key handoff

    We operate every lock repeatedly, confirm that the door latches and bolts cleanly, and hand over working keys. For rebuilds we can also help organize who holds which key, so construction crews and owners are kept separate.

What affects the price

  • Whether the job is rekeying existing hardware or supplying and installing entirely new locksets, since new hardware adds material cost.
  • The number of doors, gates and other locks involved, especially on larger lots with side-yard and gate locks.
  • Hardware grade and finish, from basic builder-grade deadbolts to higher-security or style-matched sets for period homes.
  • Condition of the existing locks, including how much extra labor is needed to free cylinders seized by heat, soot or ash.
  • Complexity of keying, such as a simple master-key system across many doors on a rebuild versus one key for the whole house.
  • Time of day and urgency, since after-hours and emergency calls differ from scheduled work.

Why Altadena chooses us

  • Fully mobile, 24/7 service with no storefront, so help comes to your property whenever you call.
  • In business since 1987, with David Shar as owner and lead technician, which means long experience with older home hardware.
  • Practical knowledge of post-fire conditions: freeing and rekeying soot-fouled deadbolts instead of defaulting to replacement when a lock can be saved.
  • Rebuild support, including keying all-new locksets, simple master-key systems and contractor lockboxes for jobsite security.
  • Honest recommendations about repair versus replacement, with options explained before work starts.
  • Comfortable working across the whole property, including gates, side-yard locks and outbuildings on larger hillside lots.

Residential Locksmith across Altadena

Altadena stretches from the busy corridors of Lake Ave, Lincoln Ave and Fair Oaks Ave up toward the foothills along Altadena Dr and Woodbury Rd. Our residential work covers both ZIP codes, 91001 and 91003. In Janes Village, many original bungalows survived with hardware that has endured months of ash exposure; we have a straightforward approach of freeing seized cylinders where we can and rekeying them so the old keys no longer work.

Around Christmas Tree Lane on Santa Rosa Avenue and near the Altadena Country Club, lots tend to be larger and hillside, which often means gate locks, side-yard entries and outbuildings alongside the main doors. When a rebuilding family buys a home in these areas, we rekey everything so they start with keys that only they hold, including the gates that are easy to forget.

For rebuilds in neighborhoods like The Meadows, we supply and key new locksets, build simple master-key systems, and set contractor lockboxes so the jobsite stays secure while construction is underway. Whether you are near Charles White Park, Farnsworth Park, or the trails by the Cobb Estate and Sam Merrill Trailhead, call (323) 997-8867 and we will come to you.

Residential Locksmith in Altadena — FAQs

Do you offer residential locksmith service in Altadena at night?
Yes. We are available 24/7 and fully mobile. Call (323) 997-8867 at any hour and we will talk through the problem and arrange to come to your Altadena home.
My deadbolt seized after the Eaton Fire. Can it be saved?
Often it can. Smoke, soot and ash can gum up cylinders and corrode internal parts. We assess each lock, free and rekey it if it is sound, and recommend replacement only when it is not worth saving. Call (323) 997-8867 to discuss it.
Can you key all the locks on a rebuilt home?
Yes. We supply and key new locksets for rebuilds and can set up a simple master-key system, so one key can open several doors while each lock stays individually keyed.
What is a contractor lockbox and do you set them?
A lockbox holds a key or access code so approved crews can enter a jobsite without copies of your house keys floating around. We set them up to help secure rebuild sites during construction.
I just bought a home near Christmas Tree Lane. Should I rekey?
We recommend it. You cannot know who holds old keys. We rekey the doors, and on larger lots we also cover gates, side-yard locks and outbuildings, so everything works on keys only you control.
Can you work on older Craftsman or Spanish Colonial hardware?
Yes. We look at whether original hardware can be repaired or rekeyed, and when replacement is better we can discuss options that suit the look of the house.
Do I have to visit a shop?
No. We are mobile only, with no storefront. A technician comes to your property with tools and hardware.
How do you price residential jobs?
Price depends on the number of locks, hardware grade, condition of existing locks, keying complexity and timing. We explain the options before work begins. Call (323) 997-8867 to talk through your specific job.
