Rekeying is the practical answer when you want old keys to stop working but the locks themselves are still in good shape. Instead of buying and installing new hardware, a technician changes the internal pins so the lock responds to a new key. The finish, the look, and the deadbolt all stay put. It is a common choice after buying a house, ending a tenancy, losing a key, or parting ways with a roommate, contractor, or former partner.

Northridge has several kinds of properties that call for it. The neighborhoods around CSUN have a lot of student-rental apartments, where keys change hands often and a fresh rekey between tenants is simply good housekeeping. The ranch tract homes built in the 1950s and 60s often still carry their original or mid-life hardware, and many have had multiple sets of keys floating around for decades. Out in Sherwood Forest, horse properties may have barn, tack-room, and gate locks that need to be keyed to work together.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work as owner and lead technician. We are fully mobile, so there is no shop to drive to. We bring the tools to your door, any hour of the day or night, and rekey on the spot whenever the lock is in workable condition.

How it works in Northridge

  1. 1

    Tell us about the locks

    Call (323) 997-8867 and describe what needs rekeying: how many doors, what types of locks, and why. A single front door after a home purchase is different from a block of apartment units or a gate and several outbuildings, and a few questions up front help us bring the right pins and key blanks.

  2. 2

    We come to you

    Because we are fully mobile, a technician travels to your Northridge address with the equipment needed. There is no storefront to visit, and we are available around the clock, including nights and weekends when a lockout of old keys is most pressing.

  3. 3

    Inspect each lock first

    Before changing anything, we check that each cylinder and deadbolt operates smoothly. Older tract-home hardware can be worn, and doors in the area may bind if the frame has shifted over the years. If a deadbolt is sticking because of alignment, we point that out and can address it alongside the rekey.

  4. 4

    Rekey the cylinders

    We remove the cylinder, replace the internal pins to match a new key, and reassemble it. The old key will no longer turn the lock. For multi-lock properties we can key several locks alike so one key works for the front door, back door, and garage entry, or for a barn, tack room, and gate.

  5. 5

    Test and hand over keys

    Each lock is tested with the new key and confirmed to turn cleanly, and we try an old key to verify it no longer works. You receive the new keys and can request extra copies on the spot.

What affects the price

  • The number of locks or cylinders being rekeyed, since each one is worked on individually.
  • Whether you want locks keyed alike so one key opens several doors, or each keyed separately.
  • The condition of the existing hardware; worn or damaged locks may be better replaced than rekeyed.
  • Lock type and brand, including high-security or restricted keyways that need special key blanks.
  • Extra services such as realigning a binding deadbolt or strike plate during the same visit.
  • Timing and location of the call, including after-hours service, and how many keys you need cut.

Why Northridge chooses us

  • Fully mobile service, so we work at your door rather than asking you to bring locks anywhere.
  • Serving the Los Angeles area since 1987, with owner David Shar leading the work.
  • Available 24/7, which suits rekeys that cannot wait, such as after a lost key or a tenant departure.
  • Comfortable handling both single-home jobs and multi-unit work, like student apartment blocks needing turnover rekeys.
  • We tell you honestly when a lock should be replaced instead of rekeyed, rather than rekeying hardware that is failing.
  • Experience with keyed-alike setups for properties with multiple buildings, gates, and outbuildings.

Lock Rekeying across Northridge

Northridge spreads across ZIP codes 91324, 91325, 91327, 91328, and 91330, and the housing varies a lot from one pocket to the next. Around the CSUN university district and along Reseda Blvd, Zelzah Ave, and Plummer St, student apartments and rentals turn over regularly, and a property manager preparing units before fall move-in may want a whole block of locks rekeyed so previous tenants' keys are dead. We can handle that kind of volume as a mobile service.

Through the Devonshire residential area and Northridge Village, many homes are 1950s and 60s ranch-style tract houses. Some of these have had frames settle since the 1994 earthquake, whose epicenter was in neighboring Reseda, and a front deadbolt that grinds or jams may need the strike plate or door alignment looked at as well as a rekey. Doing both in one visit saves a second trip.

In Sherwood Forest, with its horsekeeping estates, the work often means barns, tack rooms, and driveway gates. We can rekey or replace those locks and key them alike so one key handles everything on the property. Whether you are near Northridge Fashion Center, off Nordhoff St, or close to the Ronald Reagan Fwy (SR-118), call (323) 997-8867 and we will come to you.

Lock Rekeying in Northridge — FAQs

What does lock rekeying mean?
Rekeying changes the internal pins of a lock so a new key operates it and the old key no longer does. The lock hardware stays the same. It is usually less costly in materials than replacing locks and keeps your existing look.
Should I rekey after buying a home in Northridge?
It is a sensible step. You cannot know how many copies of the old keys exist, whether with prior owners, agents, or contractors. Rekeying makes sure only the keys you hold work. Call (323) 997-8867 to schedule it.
Can you rekey a whole student apartment complex near CSUN?
Yes, we can handle multiple units, including turnover rekeys before a semester begins. Call (323) 997-8867 with the number of doors and lock types so we can plan the visit properly.
My deadbolt is jammed in an older tract home. Can it be fixed and rekeyed?
Often, yes. In homes where the frame has settled over time, a deadbolt may bind because the bolt and strike no longer line up. We can inspect, adjust or realign, and rekey in the same visit when the lock itself is sound.
Can you key my barn, tack room, and gate locks alike?
Yes. For Sherwood Forest horse properties and similar setups, we can rekey or replace locks and key them so a single key opens all of them, or set up separate keys where you prefer access control.
When is replacing a lock better than rekeying?
If a lock is badly worn, damaged, or no longer secure, new hardware makes more sense. We will tell you plainly during inspection instead of rekeying something that will keep causing trouble.
Do you have a shop I can visit in Northridge?
No, we are fully mobile with no storefront. A technician comes to your location, and you can reach us at any hour at (323) 997-8867.
Is rekeying available at night or on weekends?
Yes, we operate 24/7. If you need locks rekeyed outside normal business hours, call (323) 997-8867 and we will arrange service.
