A lot of La Puente was built in the 1950s and 60s, and many of those single-story stucco tract homes still have the original or builder-grade locks on the front door. After decades of sun, daily use and a few hundred thousand turns of the key, those locks get loose, sticky or sloppy. A deadbolt that has to be jiggled, a knob that spins freely, or a key that only works if you lift the door a little are all signs that replacement will serve you better than another repair.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has seen just about every way an aging lock can fail. We are fully mobile. There is no storefront to visit, because we bring the tools and hardware to your door at any hour, day or night.

Lock replacement is more than swapping one piece of metal for another. It is a chance to decide who has keys, to match several doors to a single key, and to fix the underlying problem, such as a door that has warped or a strike plate that no longer lines up. We look at the whole door so the new lock works smoothly and keeps working.

How it works in La Puente

  1. 1

    Tell us what is happening

    Call (323) 997-8867 and describe the door: front entry, back door, converted garage, apartment unit or storefront. Tell us what the lock is doing, whether it sticks, spins, has a broken key, or is simply old. This helps us bring the right hardware.

  2. 2

    We come to you

    Because we are fully mobile and available 24/7, a technician drives to your address with tools and a range of locksets, deadbolts and cylinders. If you are locked out, we deal with getting you in first, then move on to replacement.

  3. 3

    Inspect the door and existing hardware

    Before removing anything, we check how the door sits in its frame. In older tract homes, a door that has swelled, sagged or warped in the sun is often the real reason a deadbolt will not throw. We check the bore holes, latch, strike plate and frame.

  4. 4

    Choose the right replacement

    We go over options with you: standard grade deadbolts, higher security hardware, keyed-alike sets for multiple doors, or commercial cylinders for storefronts. You decide what fits your door, your needs and your budget.

  5. 5

    Install and align

    We remove the old lock, install the new hardware, and adjust or reinforce the strike plate so the bolt extends fully and cleanly. We aim for a lock that turns easily without forcing the door.

  6. 6

    Test and hand over keys

    We test every key and operate the lock several times with the door open and closed. You get all of the new keys, and we explain how to get extra copies. Old keys no longer work with the new hardware.

What affects the price

  • The type of lock: a basic keyed knob, a deadbolt, a smart or keypad lock and a commercial-grade cylinder all differ in hardware cost and in installation effort.
  • The number of doors involved, especially when you want the main house, a garage conversion or ADU, and side doors all keyed alike.
  • The condition of the door and frame: if a warped door, enlarged bore or damaged strike plate needs correcting, that adds labor beyond a simple swap.
  • Security grade and finish: higher-grade deadbolts and specialty finishes cost more than builder-grade hardware.
  • Commercial requirements: aluminum storefront doors often use specialty cylinders, pivots or narrow-stile hardware that must be matched to the existing door.
  • Time of service: after-hours, weekend and emergency calls can differ from scheduled daytime visits, and a lockout on top of replacement adds work.

Why La Puente chooses us

  • Fully mobile since 1987: we work at your door, so you never have to drive anywhere or leave a house unsecured while you shop for hardware.
  • We diagnose the door, not just the lock. A sticking deadbolt on a sun-warped 1950s door may need realignment as well as new hardware, and we say so honestly.
  • Experience with local building types: tract-home entries, 1970s apartment doors, converted garage ADUs and aluminum-storefront commercial doors.
  • Keyed-alike planning for landlords and homeowners with extra units, so one key can cover the main house and the ADU while still allowing separate control where you want it.
  • Straightforward recommendations: we explain what is worn out and what is fine, so you are not sold hardware you do not need.
  • Available around the clock, including nights and weekends, for failed locks that cannot wait.

Lock Replacement across La Puente

La Puente sits between the I-10 and SR-60, with Valley Boulevard and Hacienda Boulevard carrying most of the commercial traffic and Amar Road crossing through the residential side. Whether you are near La Puente Park, a few blocks from The Donut Hole, or tucked into a quiet street in 91744, 91746 or 91747, we come to you. We also serve the neighboring unincorporated communities of Valinda and Bassett, as well as the Hudson and Sunset areas.

Much of the housing here is the classic post-war stucco tract home on a modest lot. On Valinda-side streets, we often see the same story: the original lockset has worn out, the front door has shifted with heat and age, and the deadbolt no longer lines up with the strike plate. Sometimes it jams shut and leaves someone locked out. In that case we get the door open, realign what needs it, and install a fresh lockset so the problem does not return.

Rental properties and extra units are common too. A landlord with a converted-garage ADU behind the main house might need both doors rekeyed or replaced and keyed alike after a tenant change. Along Valley Boulevard and Hacienda Boulevard, small retailers with aluminum-storefront doors sometimes need a failed deadbolt, pivot or cylinder replaced quickly. We handle both residential and commercial replacement, and you can reach us anytime at (323) 997-8867.

Lock Replacement in La Puente — FAQs

How do I know if I should replace my lock instead of repairing it?
If the lock is original to a 1950s or 60s home, has worn internals, spins loosely, sticks even after lubrication, or has a damaged cylinder, replacement is usually the better choice. We will inspect it and tell you honestly which makes sense. Call (323) 997-8867 to talk it through.
Can you replace locks at night or on weekends in La Puente?
Yes. We are mobile and available 24/7, including nights, weekends and holidays. Call (323) 997-8867 and we will send a technician to your address.
My deadbolt will not turn and the door seems warped. What can you do?
This is common on older stucco tract homes. We check the door and strike alignment, correct what we can on site, and replace the lockset if it is worn or damaged. If you are locked out, we open the door first.
Can you key my house and my converted garage ADU alike?
Yes. We can install or rekey hardware so one key works for both the main house and the ADU. We can also arrange separate keys if you want each unit controlled independently.
Do you replace commercial locks on Valley Boulevard storefronts?
We do. Aluminum-storefront doors often use specialty cylinders, pivots or narrow-stile hardware, and we can replace failed commercial deadbolts and cylinders on site.
Will my old keys still work after replacement?
No. New hardware comes with new keys, and the old keys will not operate it. That is one reason replacement is useful after a move, a tenant change or lost keys.
Do I need to come to a shop to pick out new locks?
No. We are fully mobile and have no storefront. We bring hardware options to you and install them on the spot.
How is the price of lock replacement determined?
It depends on the lock type, the number of doors, door and frame condition, security grade and the time of service. Describe your situation at (323) 997-8867 and we will explain what affects your job.
