Rekeying changes the inside of a lock so a new key operates it and every old key becomes useless. The lock itself stays on the door. That makes it a practical choice after buying a home, ending a tenancy, parting ways with a roommate or contractor, or losing a set of keys. In North Hills, where postwar tract homes sit beside blocks of older apartments, the need comes up constantly.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business around being fully mobile. There is no storefront to visit. We bring the tools and pinning supplies to your door, work on site, and test each lock before we leave. We are available around the clock, so a rekey after a late move-in or a sudden change in who has keys does not have to wait for business hours.
Not every lock is a good rekey candidate. A solid, working deadbolt is usually ideal. A worn, loose, or damaged lock is often better replaced, and we will tell you plainly which situation you have rather than selling more than the door needs.
How it works in North Hills
- 1
Tell us about the doors
Call (323) 997-8867 and describe what needs rekeying: a single-family home, several apartment units, or a commercial door. Tell us the brands if you know them, and whether you want every lock on one key.
- 2
We come to you
Because we are fully mobile, a technician travels to your North Hills property with the equipment needed to rekey on the spot. We confirm who is authorized to request the change before starting work.
- 3
Inspect each lock
We check the condition of every cylinder, deadbolt, and handleset. Locks that operate smoothly are good rekey candidates. Worn hardware, such as a tired security-screen-door latch, can be flagged for replacement at the same visit.
- 4
Rekey to a new key pattern
We remove the cylinders, replace the internal pins to match a new key, and reinstall. If you want several doors keyed alike, we match them so one key opens the front, back, and any other doors you choose.
- 5
Test and hand over keys
We try the new keys in every lock, confirm the old keys no longer turn, and check that bolts throw and latches catch cleanly. You get the new keys and can request extra copies.

Plan for larger properties
For apartment buildings, we can discuss a master-key arrangement so each unit has its own key while management holds a key that opens the set, which is useful after tenant turnover.

What affects the price
- The number of locks or cylinders being rekeyed, since each one is disassembled and repinned.
- Lock brand and type, because some deadbolts, handlesets, and commercial cylinders take more work or parts than others.
- Whether you want locks keyed alike, or a master-key system with separate unit keys and a management key.
- The condition of the hardware, including whether any worn locks should be replaced instead of rekeyed.
- How many extra keys you want cut for family members, tenants, or staff.
- Timing and location of the visit, including after-hours service for an urgent rekey.

Lock Rekeying across North Hills
North Hills splits into two quite different lock environments. North Hills West is mostly 1950s and 60s single-family tract homes, where a rekey often covers the front deadbolt, back door, and a security-screen-door lock that may be showing its age. North Hills East is denser, with many 1960s and 70s dingbat and garden-apartment buildings and more rental turnover, so owners and property managers there often need several units rekeyed at once, plus mailbox or cluster-box locks.
We work throughout ZIP code 91343, from homes near North Hills Community Park to buildings off Roscoe Boulevard and Devonshire Street. Along Nordhoff Street, Roscoe, and Sepulveda Boulevard, storefronts with aluminum-frame glass doors often use Adams Rite-style deadlatches, which can be rekeyed or replaced after an attempted break-in.
Whether you are near the Sepulveda Basin Recreation Area, close to the VA Sepulveda Ambulatory Care Center, or just off the I-405, we come to you. Call (323) 997-8867 any hour to arrange a rekey.
