Locks wear out quietly. A deadbolt that needs a little jiggle, a knob that spins freely, a key that has been copied so many times it barely turns: these are signs it is time to replace the hardware rather than keep patching it. In Alhambra, the doors in question range from original 1920s Craftsman entries to aluminum storefront doors on Valley Boulevard, and each calls for different thinking.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar and our team are fully mobile. There is no shop to drive to. We bring hardware and tools to your door, look at what is installed, and explain your options before we change anything. Sometimes the right answer is a brand-new lock. Sometimes it is repairing or rekeying what you already have, and we will tell you honestly which makes sense.

A replacement is also a chance to fix the real problem. If you have lost keys, ended a tenancy, had a break-in, or just bought a house with an unknown number of keys floating around, new locks reset who has access. We can match finishes, choose grades suited to the door, and set multiple locks to a single key so you are not carrying a ring of them.

How it works in Alhambra

  1. 1

    Tell us about the door and the problem

    Call (323) 997-8867 any hour. Describe the door, what the lock is doing, and why you want it replaced, whether that is wear, a break-in, lost keys or a change of tenants. This helps us bring the right hardware.

  2. 2

    On-site inspection

    We come to you and examine the lock, strike plate, latch and the door itself. Older Alhambra bungalows often have mortise pockets or hardwood doors that limit what will fit, and storefront doors have narrow stiles, so we check before recommending anything.

  3. 3

    Options explained before work begins

    We lay out the realistic choices: replace with a new deadbolt or handleset, repair or rekey an original mortise lock, or upgrade the grade of hardware. You decide, and you know the approach before we start.

  4. 4

    Careful removal and installation

    We remove the old lock without needlessly damaging the door, correct fit issues such as misaligned bores or loose strike plates, and install the new hardware so it operates smoothly rather than just fitting.

  5. 5

    Keying to your needs

    New locks can be keyed alike so one key opens several doors, or set up with separate keys for different people or units. We cut and test keys on site.

  6. 6

    Testing and handoff

    We test every lock and key repeatedly, with the door open and closed, and walk you through how it works. Old hardware can be left with you or taken away, as you prefer.

What affects the price

  • The type of lock: a basic deadbolt, a keyed handleset, a smart lock and a commercial-grade cylinder all differ in hardware cost.
  • The number of locks being replaced and whether they are keyed alike, since more cylinders mean more parts and more time on site.
  • Door condition and construction: older wood doors, original mortise preparations or aluminum storefront stiles can require extra fitting or adapter work.
  • The hardware grade and finish you choose, including matching existing finishes throughout a home or building.
  • Whether the job is a scheduled visit or an emergency call outside normal hours, since we are available 24/7.
  • Additional work found on inspection, such as a damaged strike plate, a door frame needing reinforcement, or broken keys that must be extracted first.

Why Alhambra chooses us

  • Fully mobile since 1987: we work at your door, so there is no storefront and no need to bring the door anywhere.
  • Familiarity with Alhambra's mix of historic Craftsman and Spanish Revival homes, mid-century apartments and Main Street commercial doors.
  • We will tell you when repairing or rekeying a good mortise lock is smarter than replacing it, instead of defaulting to the bigger job.
  • Keying plans built around how you actually live or operate, including keyed-alike sets, per-unit keys and building-wide rekeying.
  • Available around the clock, so a break-in or lockout does not have to wait for business hours.
  • Direct conversations with experienced technicians, with no pressure to buy hardware you do not need.

Lock Replacement across Alhambra

Alhambra has long called itself the City of Homes, and its housing shows it. In the Bean Tract and Midwick Tract, both among the city's designated historic neighborhoods, many bungalows still carry original mortise locks and period doorsets on wood-frame doors. Replacement there takes judgment: a seized mortise lock may be worth repairing, and when new hardware is the better choice, we look for options that suit the character of the house. Emery Park and the Airport Tract have their own mix of older single-family homes where worn deadbolts and loose strikes are common.

Across town, mid-century apartment and courtyard buildings often need locks replaced between tenancies, along with common-area doors and mailbox locks. We can plan the keying so each unit has its own key while shared doors work for the right people. Around Downtown Alhambra, Main Street and Valley Boulevard, shops and restaurants with aluminum storefront doors may need a replacement cylinder or a new lock before opening, and we can work around your schedule, including early mornings or late nights.

Whether you are in 91801 near Main Street, in 91803 closer to the Airport Tract, or near Almansor Park, Garfield Theatre or the Fremont Avenue and Atlantic Boulevard corridors, we come to you from wherever our crew is working, with I-10 and the surrounding streets making most of the city reachable. Call (323) 997-8867 to schedule lock replacement anywhere in Alhambra.

Lock Replacement in Alhambra — FAQs

How do I know whether to replace or just rekey a lock in Alhambra?
If the lock works smoothly and is in good shape, rekeying is often enough to cancel old keys. Replacement makes sense when the lock is worn, damaged, low quality or being upgraded. Call (323) 997-8867 and we will help you decide.
Can you replace the original mortise locks in my older Alhambra bungalow?
Yes, but we usually evaluate repair first. Many original mortise locks in Bean Tract and Midwick Tract homes can be restored or rekeyed. If replacement is better, we look for hardware that fits the existing mortise pocket.
Do you offer lock replacement at night or on weekends?
Yes. We are available 24/7 and fully mobile, so you can call (323) 997-8867 any time, including after a break-in or when a lock fails.
Can you replace locks on my Main Street storefront?
Yes. We work on aluminum storefront doors and can replace cylinders or locksets, extract broken keys and rekey, often before your business opens.
What affects the cost of replacing a lock?
Cost depends on the lock type and grade, how many locks you need, the door's condition, finish choices and whether the call is an emergency. We explain the factors and options before starting work.
Can all my locks use one key?
Usually, yes. We can key new deadbolts and handlesets alike so one key works at several doors, as long as the hardware is compatible.
I manage an apartment building. Can you handle many units?
Yes. We can replace or rekey unit locks, common-area doors and mailbox locks, with a keying plan that fits your turnover. Call (323) 997-8867 to discuss your building.
Do I need to visit a shop?
No. Crenshaw Lock Company is mobile only. We come to your home or business anywhere in Alhambra and do the work on site.
