A lock does not last forever. Deadbolts loosen, latches stick, keys wear down until they barely turn, and a lock that has passed through a few tenants or a break-in attempt is no longer one you can fully trust. Replacing it is often the cleanest fix, and in North Hills the reasons vary a lot from one block to the next.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile, with no storefront to visit. We bring hardware and tools to your door, whether that is a tract home off Devonshire Street, a garden-apartment building near Sepulveda Boulevard, or an aluminum-frame shop along Nordhoff Street.

Replacement is not always the right answer, and we will say so. Sometimes a rekey does the job for less. When the hardware itself is the weak point, such as a worn security-screen-door latch, a loose knob set or a damaged deadlatch, we replace it and set it up properly so it works smoothly for years.

How it works in North Hills

  1. 1

    Call and describe the door

    Call (323) 997-8867 at any hour. Tell us what kind of door it is, what the lock is doing, and whether the problem is wear, damage, a lost key or a recent break-in attempt. That helps us bring the right hardware.

  2. 2

    On-site assessment

    We look at the lock, the door, the strike plate and the frame. Many failures come from a misaligned door or a loose strike, not just the lock. If a rekey would solve it, we will explain that option.

  3. 3

    Choose the hardware

    We go over options for the door in front of us: deadbolts, entry sets, security-screen-door latches, or commercial deadlatches for storefront doors. You choose the grade and finish, and whether several locks should share one key.

  4. 4

    Remove and install

    We take out the old lock and fit the new one cleanly, checking bore, latch and strike alignment. On a damaged door we address the damage so the new lock seats correctly instead of binding.

  5. 5

    Test and hand over keys

    We cycle the lock repeatedly with the door open and closed, confirm it throws fully, and hand over your keys. Multi-unit jobs get a clear key plan so you know what opens what.

What affects the price

  • The type of lock: a basic residential deadbolt differs from a high-security cylinder or a commercial deadlatch.
  • How many locks are being replaced, and whether they will be keyed alike or on a master-key system.
  • Door condition: a damaged, drilled or misaligned door may need repair work so the new lock seats properly.
  • Door and frame type, such as wood, metal, security screen or aluminum storefront, which affects the hardware that fits.
  • Finish and grade chosen, from standard to heavier-duty hardware.
  • Time of day, since we answer 24/7 and an after-hours call involves different scheduling than a planned daytime visit.

Why North Hills chooses us

  • Fully mobile since 1987: we work at your door and there is no shop to drive to.
  • Owner-led by David Shar, with decades of hands-on experience behind the work.
  • Honest about rekey versus replace: we recommend the lesser fix when it truly protects you.
  • Familiar with North Hills building stock, from 1950s-60s tract homes to 1960s-70s dingbats and garden apartments.
  • Comfortable with both residential and commercial hardware, including Adams Rite-style deadlatches on aluminum storefronts.
  • Available 24/7, so a broken lock after a break-in attempt does not have to wait until morning.

Lock Replacement across North Hills

North Hills sits in the San Fernando Valley, once part of the Mission Acres agricultural tract and the community formerly called Sepulveda. In North Hills West, most homes are 1950s-60s single-family tract houses. Their original locks are often decades old, and many have security screen doors whose latches wear out long before the main deadbolt does. A lockout there often ends with a worn screen-door lock replaced at the same visit.

North Hills East is denser, with many 1960s-70s dingbat and garden-apartment buildings and more tenant turnover. For property managers there, replacement usually means changing locks across several units, fixing worn mailbox or cluster-box locks, and setting up a master-key system after a wave of move-outs. We plan those jobs so keys are organized and every unit is tested.

Our work covers ZIP code 91343 and the surrounding area, from homes near North Hills Community Park and the Sepulveda Basin Recreation Area to apartments near the VA Sepulveda Ambulatory Care Center. Along Nordhoff Street, Roscoe Boulevard and Sepulveda Boulevard, we also replace and rekey commercial hardware, such as an Adams Rite deadlatch on an aluminum-frame glass door after an attempted break-in. Whether you are off the I-405 or deep in a residential block, call (323) 997-8867.

Lock Replacement in North Hills — FAQs

Should I replace my lock or just rekey it?
If the lock works smoothly and is in good shape, rekeying is often enough to make old keys useless. If it is worn, damaged, loose or outdated, replacement is better. Call (323) 997-8867 and we will tell you which fits your door.
Do you replace locks at night and on weekends?
Yes. We are available 24/7 and fully mobile, so you can call (323) 997-8867 at any hour for lock replacement in North Hills.
Can you replace the lock on a security screen door?
Yes. Many 1950s-60s homes in North Hills West have security screen doors with worn latches. We can replace the screen-door lock, often during the same visit as another lock service.
Can you replace several locks and key them alike?
Yes. We can key multiple locks the same so one key opens them all, which suits many homeowners. For apartment buildings we can also set up a master-key system.
Do you handle apartment buildings in North Hills East?
Yes. With heavy tenant turnover, buildings often need multiple unit locks replaced or rekeyed, plus mailbox lock attention. We plan the job around your units and key needs.
Can you replace commercial storefront locks along Nordhoff Street?
Yes. We work on aluminum-frame glass doors, including Adams Rite-style deadlatches, and can replace and rekey them after an attempted break-in.
Do I need to be home during replacement?
An authorized person should be present, since we verify who has the right to change the lock. The work itself is usually straightforward, and we test everything with you before finishing.
Is there a storefront I can visit?
No. Crenshaw Lock Company is fully mobile and comes to you. To get started, call (323) 997-8867.
