Locks do not last forever. In a city as established as Covina, it is common to find hardware that has been turning for decades: a tired knob on a post-war tract house, a deadbolt that sticks every time the weather changes, or a front-door lock on a Craftsman bungalow that no one can say who holds keys to. Replacing the lock, rather than just repairing or rekeying it, is often the right move when the parts themselves have worn out or no longer match what you need.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile. There is no storefront to visit; we bring the tools and a selection of hardware to your home, apartment or business in Covina, at any hour, including nights, weekends and holidays.

Lock replacement is different from a rekey. A rekey changes the internal pins so old keys stop working while keeping the same lock body. A replacement installs entirely new hardware: new cylinders, deadbolts, knobsets, levers or handlesets. We will help you decide which one makes sense, and we will tell you plainly if a simpler fix will do the job.

How it works in Covina

  1. 1

    Call and describe the door

    Phone (323) 997-8867 and tell us which door it is, what type of lock is on it now, and what is going wrong. A sticking deadbolt, a loose handle, a lock after a break-in attempt and a lock you simply want to upgrade each call for different hardware.

  2. 2

    We come to you

    Because we are mobile and available around the clock, we travel to your Covina address with tools and common hardware on the truck. Whether you are near Citrus Ave downtown or in a quieter Covina Hills cul-de-sac, the work happens at your door.

  3. 3

    Inspect the door and existing hardware

    Before removing anything, we check the door thickness, bore holes, strike plate, latch alignment and the condition of the frame. Older doors in Covina's bungalows sometimes have mortise pockets or non-standard preps that affect what can be installed.

  4. 4

    Choose the right replacement

    We go over your options: standard grade deadbolts, higher-security cylinders, keyed-alike sets so one key runs every door, or keypad and smart-lock models. You decide based on how you live and what you want to protect.

  5. 5

    Install and fit-check

    We remove the old lock, install the new hardware, and adjust the latch and strike so the bolt throws smoothly and fully. Where a frame is worn or a strike plate is weak, we can address that so the new lock is not undermined by the door around it.

  6. 6

    Test and hand over keys

    We cycle the lock several times with the door open and closed, confirm every key works, and walk you through any special features. You leave with working keys and a door that closes and locks the way it should.

What affects the price

  • The type of lock: a basic knobset, a deadbolt, a full handleset or a keypad or smart lock all involve very different hardware.
  • Security grade and brand of the hardware you select, from standard residential to heavier-duty options.
  • How many locks are being replaced, and whether you want them keyed alike so one key opens every door.
  • The condition and type of the door, including older mortise or rim locks, unusual bore sizes, or frame repairs needed for a proper fit.
  • Whether the work is scheduled in advance or needed urgently at night, on a weekend or on a holiday.
  • Any extras such as reinforced strike plates, additional keys or matching finishes for the entire entry.

Why Covina chooses us

  • Fully mobile, 24/7 service: we come to your Covina door instead of asking you to bring anything to a shop, because we do not have a storefront.
  • Serving Greater Los Angeles and Ventura County since 1987, with David Shar as owner and lead technician.
  • Honest recommendations: if a rekey or a small repair solves the problem, we say so rather than selling new hardware you do not need.
  • Familiarity with older homes: we understand the original mortise and rim locks found in 1920s and 1930s Craftsman and Spanish bungalows, as well as the typical hardware on post-war tract houses.
  • Hardware choices for different needs, from simple replacement to keyed-alike sets and keypad options.
  • We test every installation and make sure the latch, strike and door alignment work together, not just that the key turns.

Lock Replacement across Covina

Covina's housing mix shapes the kind of lock replacement people ask about. In and around historic Downtown Covina, near Citrus Ave, Heritage Plaza and the Covina Center for the Performing Arts, 1920s and 1930s buildings and bungalows often still carry original mortise or older rim locks. Those can be worn beyond reliable use, and fitting modern hardware may take careful work on the door. Small downtown shops and offices have their own needs, such as replacing a tired storefront lock or upgrading after an employee leaves.

East of downtown, Charter Oak (91724) is largely post-war single-family tract housing, where a common request is replacing every lock after a home purchase closes, so no previous owner, contractor or neighbor still holds a working key. Further south, Covina Hills brings ranch-style homes on larger lots, where people often want better-quality front-door hardware, matching handlesets, or garage and side-gate entry points secured. Residents in 91722 and 91723 have similar needs, including apartments where a landlord or tenant wants a lock changed after a move-out.

Whether you commute through the Covina Metrolink station, drive Interstate 10, or travel Azusa Ave, Grand Ave, Badillo St, San Bernardino Rd or Arrow Hwy, a lock that will not secure your door is an urgent problem at any hour. Call (323) 997-8867 and we will come to you anywhere in Covina.

Lock Replacement in Covina — FAQs

What is the difference between lock replacement and rekeying in Covina?
Rekeying changes the internal pins of your existing lock so old keys no longer work. Replacement installs new hardware entirely. Rekeying suits good locks in good condition. Replacement suits worn, damaged, loose or outdated locks, or when you want a different style or security level. Call (323) 997-8867 and we can help you decide.
Do you offer lock replacement at night or on weekends?
Yes. Crenshaw Lock Company is available 24/7 and fully mobile, so we can replace locks at your Covina home or business at night, on weekends and on holidays. Call (323) 997-8867 to reach us.
Can you replace the original locks on an older Covina bungalow?
Often, yes. Many 1920s and 1930s homes near downtown have mortise or older rim locks. We inspect the door first to see whether the original lock can be restored, replaced with a matching style, or converted to a modern deadbolt without damaging the door.
Should I replace all my locks after buying a home?
It is a smart step, since you cannot know who holds copies of the old keys. Depending on the condition of the hardware, we can either replace the locks or rekey them. Many buyers in areas like Charter Oak choose to have every exterior door done at once, and we can set them up keyed alike.
Do you have a shop in Covina I can visit?
No. We are a mobile-only service with no storefront. We come to your door anywhere in Covina, including the 91722, 91723 and 91724 ZIP codes, with tools and hardware ready.
What affects the cost of replacing a lock?
The main factors are the type and security grade of the lock, how many you need, the condition and type of your door, and whether the visit is urgent or after hours. We discuss your options before starting so there are no surprises.
Can you install a keypad or smart lock?
Yes, we can install keypad and smart lock options on suitable doors. We will check the door and frame first, and explain how the lock works, how to manage codes, and what to do if batteries run low.
What if my lock was damaged in a break-in attempt?
Call us right away at (323) 997-8867. We can replace the damaged lock, check the door and frame for weakness, and suggest reinforcement such as a stronger strike plate so your door is secure again.
