A lock that sticks, spins loosely, or refuses to throw the bolt is usually telling you something specific: a worn cylinder, a door that has shifted, a strike plate that no longer lines up, or debris inside the mechanism. Often it can be repaired rather than replaced, which keeps a good lockset on a door you already like and saves you from buying hardware you do not need.

Altadena has its own set of lock problems. Many homes here date from the 1910s through the 1940s, with Craftsman bungalows, Spanish Colonial houses and mid-century builds, and old doors settle, swell and warp over decades. On top of that, the January 2025 Eaton Fire left surviving homes with deadbolts and latches that were exposed to heat, smoke, soot and months of ash, and some of those cylinders have seized or grown gritty and stiff.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile, with no storefront to visit. We come to your door at any hour, diagnose the actual cause, and repair what can be repaired. If something is truly past saving, we tell you plainly and talk through replacement options.

How it works in Altadena

  1. 1

    You call, we talk through the symptoms

    Call (323) 997-8867 any time, day or night. Tell us what the lock is doing: sticking, turning only part way, wobbling, jamming with the key, or refusing to latch. Those details help us bring the right parts and tools.

  2. 2

    We come to you

    Because we are fully mobile, the repair happens at your door, whether that is a bungalow in Janes Village, a hillside home, or a rebuild site. There is no need to remove hardware and carry it anywhere.

  3. 3

    Diagnose the real cause

    We test the key, cylinder, bolt, latch, strike plate and door alignment separately. A lock that seems broken is often fine inside while the door has shifted, or the reverse. On fire-exposed hardware we check for soot, ash and heat damage to internal parts.

  4. 4

    Repair, clean or re-align

    Depending on what we find, we may clean and service a fouled cylinder, tighten or reset loose hardware, adjust or reposition a strike plate, correct a misaligned bolt, or replace a single worn component rather than the whole lockset.

  5. 5

    Rekey or replace only if needed

    If a cylinder is too far gone, we explain the options, including rekeying or a new lockset that matches your door and your style. You decide before any replacement work begins.

  6. 6

    Test and hand back

    We cycle the lock repeatedly with the door open and closed, confirm every key works smoothly, and make sure the door latches and locks without force before we leave.

What affects the price

  • The type of lock involved: a basic deadbolt, a mortise lock in an older home, a smart lock, or a multipoint system each require different time and parts.
  • Whether the fix is an adjustment or cleaning, or involves replacing internal components or an entire cylinder.
  • The condition of the hardware, especially fire-, heat- or soot-exposed locks that may need more intensive servicing.
  • The number of locks being repaired in one visit, including gates, side-yard doors and outbuildings on larger lots.
  • Door and frame condition, since warped, swollen or shifted doors can add alignment work beyond the lock itself.
  • Time of day and the specifics of the call, since we are available around the clock and after-hours work is part of the picture.

Why Altadena chooses us

  • Fully mobile since 1987: the repair is done at your door, with no shop to drive to.
  • Repair first, replace only when necessary, so you keep sound hardware and avoid unneeded cost.
  • Familiarity with older Altadena homes, including Craftsman and Spanish Colonial doors that have settled and shifted over many decades.
  • Experience with soot- and heat-affected cylinders on surviving homes after the Eaton Fire.
  • Owner-led work under David Shar, with clear explanations of what is wrong and what your options are.
  • Available 24/7, so a lock that fails at night does not have to wait for morning.

Lock Repair across Altadena

Altadena runs from the foothills near the Cobb Estate and Sam Merrill Trailhead down toward Lincoln Ave and Lake Ave, and its housing varies block by block. In Janes Village, many older bungalows still carry original doors and hardware that have been through eighty years or more of seasons, and the Eaton Fire added smoke and ash exposure on top of that. Near Christmas Tree Lane along Santa Rosa Avenue, and around the Altadena Country Club and The Meadows, larger lots often mean extra gates, side-yard doors and detached structures that all have locks of their own.

We work throughout the 91001 and 91003 ZIP codes, from homes near Fair Oaks Ave and Woodbury Rd to those up along Altadena Dr. A typical call might be a seized deadbolt on a surviving bungalow that needs freeing and servicing, or a hillside home whose new owners want sticky exterior locks and gate hardware sorted out.

Many properties here are also in some stage of recovery. For rebuilds, we can repair or adjust hardware on partially finished doors, and contractors can call us when jobsite locks or lockboxes misbehave. Whether you live near Charles White Park, Farnsworth Park, or the old Mount Lowe Railway site, call (323) 997-8867 and we will come to you.

Lock Repair in Altadena — FAQs

Can a lock damaged by smoke and soot be repaired?
Often, yes. Cylinders that seized or grew stiff from soot and ash can sometimes be cleaned and serviced. If internal parts are heat-damaged or corroded, we may replace the cylinder or lockset. Call (323) 997-8867 and describe what it is doing.
Do you repair locks at night or on weekends in Altadena?
Yes. We are a 24/7 mobile service, so you can call (323) 997-8867 at any hour and we will come to your door.
Should I repair or replace a sticking deadbolt?
It depends on the cause. If the problem is dirt, a loose fastener or a misaligned strike plate, repair is usually enough. If the cylinder is worn out or damaged, replacement makes more sense. We diagnose first and explain before doing anything.
Why does my deadbolt not line up with the strike plate?
Older doors in Altadena settle, swell and shift with the seasons, which moves the bolt away from the strike. We can adjust or reposition the strike plate, or address the door fit, so the bolt throws smoothly.
Can you fix locks on gates and side-yard doors?
Yes. Larger lots near areas like Christmas Tree Lane and the Country Club often have gate and side-yard locks, and we can repair or rekey those during the same visit.
Do you have a shop I can bring my lock to?
No. We are fully mobile only and have no storefront. We do the repair at your property.
Can you help with locks on a home under reconstruction?
Yes. We can repair or adjust hardware, help with jobsite lockboxes, and work with contractors on securing the site. Call (323) 997-8867 to talk through your situation.
What affects the cost of a lock repair?
Mainly the type of lock, the extent of damage, how many locks are involved, door condition and time of day. We explain the situation and options before work begins.
