A lock that sticks, spins loose, or no longer feels trustworthy is worth replacing before it fails on a bad night. In Rowland Heights, that might be a worn deadbolt on a two-story tract home near Powder Canyon, a smart lock that has gone dark, or a tired storefront deadbolt on a restaurant door off Colima Rd. Replacement means removing the old hardware and fitting new locks that suit the door and the way you use it.

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, so there is no shop to drive to. We come to your property, look at the door, and replace the lock there, any hour of the day or night.

Replacement is different from rekeying. Rekeying changes the internal pins so old keys stop working while the hardware stays. Replacement makes sense when the lock is physically worn, damaged after a break-in attempt, outdated, or simply not the grade of security you want. If you are unsure which you need, we will tell you plainly, even when the answer is the less involved option.

How it works in Rowland Heights

  1. 1

    Tell us about the door

    Call (323) 997-8867 and describe what is happening: a stuck deadbolt, a broken handle, a dead smart lock, a jammed storefront cylinder. Tell us whether it is a house, a suite, or a rear restaurant door. That helps us bring the right hardware on the first trip.

  2. 2

    We come to you

    Because we are mobile and available 24/7, a technician travels to your home or business in Rowland Heights. There is no storefront to visit. Nights, weekends and holidays are handled the same way.

  3. 3

    Inspect the lock and door

    We check the existing hardware, the door edge, the strike plate and the frame. A worn lock is sometimes a symptom of a misaligned door, and on aluminum storefronts the cylinder and latch style limit what will fit. We explain what we find before changing anything.

  4. 4

    Choose the replacement hardware

    We go over options that fit your door: standard deadbolts, higher-security cylinders, keyed-alike sets so one key opens several doors, or smart locks. For commercial doors we talk through storefront deadbolts and exit hardware that suit the application.

  5. 5

    Install and test

    We remove the old lock, fit the new one, and align the bolt and strike so it throws smoothly. We cycle it repeatedly with the door open and closed, and test every key before we leave.

  6. 6

    Hand over keys and tips

    You receive all keys and a short walkthrough. For smart locks, we show you how the battery, backup key and codes work so a dead battery does not leave you stuck outside again.

What affects the price

  • The type of lock: a basic residential deadbolt, a high-security cylinder, a smart lock, and commercial storefront or panic hardware all differ in material and labor.
  • How many locks are being replaced in one visit, such as a whole house or several suites in a plaza, and whether they should be keyed alike.
  • Door and frame condition, since a warped door, damaged strike or bored-out hole may need extra work to fit new hardware properly.
  • Whether the work is urgent or after hours, such as a restaurant that must be secured overnight.
  • Brand and security grade of the hardware you select, as well as any special features like rekey-friendly cylinders or restricted keyways.
  • Whether we are also dealing with a lockout or damage from a break-in attempt alongside the replacement.

Why Rowland Heights chooses us

  • Fully mobile and open 24/7, so a broken lock at midnight in Rowland Heights does not have to wait for a shop to open.
  • In business since 1987, with owner and lead technician David Shar directing the work.
  • Experience with both residential and commercial hardware, from tract-home deadbolts to aluminum-storefront locks and panic bars.
  • We tell you honestly whether replacing or simply rekeying makes more sense, so you pay for what the door needs.
  • We handle multi-lock jobs in a single visit, helpful for property managers turning over several suites.
  • We test the work before leaving and show you how smart locks and backup keys work.

Lock Replacement across Rowland Heights

Rowland Heights sits in ZIP code 91748, a mix of hillside homes and busy commercial corridors, and the locks here reflect both. In the Powder Canyon hillside tracts and the Fairway Dr area, many homes are two-story tract houses from the 1970s and 80s on view lots climbing toward the canyon. After decades, original deadbolts and handle sets are often worn, and a growing number of owners are switching to smart locks, which brings its own problem: a dead battery can lock you out of your own front door.

Down in Little Taipei, the Colima Rd and Nogales St core is dominated by multi-tenant plazas like Diamond Plaza, Hong Kong Plaza and Pearl Plaza. Restaurants, markets and offices above retail rely on aluminum-storefront deadbolts, roll-gate padlocks and panic or exit hardware. A jammed storefront deadbolt or a worn panic bar after closing is a real problem, and a plaza manager may need several suite locks changed between tenants in one trip. Our mobile service suits that kind of work.

Whether you live off Fullerton Rd, near Schabarum Regional Park, or commute along SR-60, we come to you. Call (323) 997-8867 any time and tell us your cross streets and the kind of door involved.

Lock Replacement in Rowland Heights — FAQs

How do I know if I need lock replacement instead of rekeying?
Rekeying works when the lock is in good shape and you just want old keys to stop working. Replacement is better when the lock is worn, damaged, loose, outdated or lower in security than you want. Call (323) 997-8867 and we will help you decide.
Do you replace locks at night in Rowland Heights?
Yes. We are available 24/7 and fully mobile, so we can come to your home or business at any hour. Call (323) 997-8867 to describe the situation.
Can you replace a smart lock that stopped working?
Often we can. Sometimes the issue is just a dead battery and the existing lock can be restored, but if the unit has failed we can install a new smart lock or a traditional deadbolt, depending on your preference.
Can you work on restaurant and plaza storefront doors?
Yes. We work on aluminum-storefront deadbolts, panic and exit hardware, and other commercial locks, including after-hours calls for businesses in the Colima Rd and Nogales St plazas.
Can several locks be replaced and keyed alike in one visit?
Yes. We can replace multiple locks and set them up so one key works across them, which is useful for homeowners and for property managers handling several suites.
Do I need to visit your shop?
No. We are mobile only and have no storefront to visit. We bring the hardware and tools to your door.
What affects the cost of replacing a lock?
The lock type and grade, how many locks, door and frame condition, and whether the call is after hours all play a part. We explain the options before starting so there are no surprises. You can reach us at (323) 997-8867.
Will new locks fit my older tract-home door?
Usually yes. Most 1970s and 80s doors accept standard modern deadbolts. If the door is worn or the bore is damaged we will tell you what extra work is needed to get a proper fit.
