Locks do not last forever. In Pasadena, a lot of them have already outlasted several owners. Deadbolts loosen, latches stick, cylinders wear until a key barely turns, and sometimes a lock is simply the wrong lock for the way a door is used today. Replacing it is often the most sensible fix, and doing it properly takes more than unscrewing one set of hardware and installing another.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar knows how different Pasadena's doors can be. One street might have a 1920s Craftsman with original brass hardware. The next might have a mid-century courtyard apartment with a builder-grade deadbolt, and a few blocks away is an aluminum-frame glass storefront. Each needs a different approach, and we do not treat them as the same job.

We are fully mobile. There is no shop to drive to, because the work happens at your door. We are available 24/7, so a lock that fails at night or on a weekend does not have to wait until Monday. Call (323) 997-8867, describe what the lock is doing, and we will talk through whether replacing it, repairing it or simply rekeying it makes the most sense.

How it works in Pasadena

  1. 1

    Tell us about the door and the problem

    When you call (323) 997-8867, we ask what kind of door it is, how old the hardware seems to be, and what has gone wrong. A sticking latch, a spinning cylinder, a broken key and a lock you simply want upgraded can each point to different solutions.

  2. 2

    Inspect the existing hardware on site

    We look at the lock, the strike, the door edge and the frame. On older Pasadena homes, we check whether the lock is a mortise, a rim lock or a modern bored set, because that determines what can be replaced without cutting into the door.

  3. 3

    Recommend replace, repair or rekey

    Not every worn lock needs replacing. If a rekey or a repair will do the job, we say so. If replacement is the better choice, we explain the options in grade, finish and function so you can decide what suits the door and your budget.

  4. 4

    Install the new hardware carefully

    We remove the old lock and fit the new one, checking alignment so the bolt throws smoothly into the strike. On historic or decorative doors, we work to avoid enlarging holes or marking original wood and brass wherever possible.

  5. 5

    Test, cut keys and walk you through it

    We operate the lock repeatedly with the door open and closed, confirm every key works, and show you how it functions. You leave with a door that locks and unlocks smoothly, and with keys that belong only to you.

What affects the price

  • The type of lock being installed, from a basic deadbolt to a higher-security grade or a smart lock, which changes both the hardware and the installation work.
  • The number of locks involved, since replacing every exterior door at once is a different job from replacing a single deadbolt.
  • The condition and age of the door and frame, because worn strike plates, misaligned doors or older mortise pockets can add preparation work.
  • Whether the locks need to be keyed alike so one key opens several doors, or master keyed for a landlord or property manager.
  • Finish and style requirements, such as matching existing brass or a particular look on a visible front door.
  • The time and location of the call, since after-hours and weekend service involve different scheduling than a planned daytime visit.

Why Pasadena chooses us

  • Fully mobile service, so the work is done at your door and there is no storefront trip or waiting while your lock is dealt with elsewhere.
  • Operating since 1987, with the practical experience that comes from handling everything from old mortise sets to modern deadbolts across Los Angeles County.
  • Honest recommendations. If a lock can be repaired or rekeyed instead of replaced, we will tell you rather than sell you hardware you do not need.
  • Respect for older doors. Pasadena has many period homes, and we take care to preserve original brass and woodwork where we can.
  • 24/7 availability for urgent situations, such as a broken lock after a break-in attempt or a failed cylinder on a business door before opening.
  • You deal directly with a working locksmith team led by owner David Shar, not a call center passing your job along.

Lock Replacement across Pasadena

Pasadena's housing tells the story of its locks. In Bungalow Heaven, many 1900s to 1930s Craftsman bungalows still carry original mortise locks, rim locks and skeleton-key sets with brass escutcheons that give the doors their character. In a protected district like that, replacing everything with a modern lockset is often not what an owner wants. Our approach is to rekey or retrofit what can be saved, and to replace only what has genuinely failed, so the door keeps its look. This comes up often after a home sale, when new owners want fresh keys without losing original hardware.

In Madison Heights and Garfield Heights, the larger 1910s and 1920s estates and foursquares have their own mix of older hardware and later upgrades. Out in Hastings Ranch, postwar homes are more likely to have standard bored deadbolts that have simply worn out with decades of use. Near PCC, Caltech and along Lake Avenue, mid-century courtyard apartments often need deadbolt upgrades at a landlord's request, or an after-hours fix when a tenant is locked out. Properties in ZIP codes like 91106 and 91101 are the kind of mix we see regularly.

Commercial doors are different again. Along Colorado Boulevard in Old Pasadena and around the Playhouse District, aluminum-frame glass storefront doors use narrow-stile hardware, and a failed cylinder before opening can stop a retailer's day. Because we are mobile, we reach homes, apartments and businesses around the Rose Bowl, Pasadena City Hall, Huntington Hospital and the I-210, SR-134 and I-110 corridors, whatever hour you call (323) 997-8867.

Lock Replacement in Pasadena — FAQs

How do I know whether I need a lock replaced or just rekeyed?
If the lock works smoothly and is in good shape but you want to change who has keys, rekeying is usually enough. If it sticks, spins, is damaged or is outdated, replacement makes more sense. Call (323) 997-8867 and we will help you decide.
Can you replace locks on a historic Craftsman home in Bungalow Heaven?
Yes. On older homes with mortise or rim locks, we try to rekey or retrofit original hardware to preserve brass and woodwork. If something has truly failed, we discuss replacement options that suit the door.
Do you offer lock replacement at night or on weekends?
Yes, we are available 24/7 and fully mobile. If a lock fails after hours, call (323) 997-8867 and we will talk through the situation and arrange service.
Do I need to visit your shop?
No. Crenshaw Lock Company is mobile only, with no storefront to visit. We bring the tools and hardware to your home, apartment or business in Pasadena.
Can you replace the lock on my storefront door on Colorado Boulevard?
Yes. We work on commercial doors, including aluminum-frame glass doors with narrow-stile hardware. If a cylinder fails before opening, call (323) 997-8867 so we can get you back in business.
I am a landlord near Lake Avenue. Can you upgrade deadbolts on my units?
Yes. We can replace or upgrade deadbolts on apartment units and can key locks alike or arrange keying that suits how you manage the property. Tell us about the doors when you call.
What affects the cost of replacing a lock?
The main factors are the type and grade of lock, how many doors are involved, the condition of the door and frame, keying needs, finish, and when the service is needed. We explain the options before we start work.
Will the new lock work with my existing door?
In most cases yes, but we check the door's thickness, bore holes and strike first. If the door needs minor adjustment or preparation, we cover that during the visit. You can reach us at (323) 997-8867 to describe your door beforehand.
