Rekeying changes the internal pin configuration of a lock so that a new key operates it and every previously issued key becomes useless. The locks stay on the door, the finish stays the same, and you get a fresh start on who has access. It is one of the most sensible things to do when you buy a house, finish a sale, end a tenancy, or let an employee go.

In Mission Hills, rekeying comes up constantly because so much of the housing is resale-driven. Many homes here are late-1940s to 1960s stucco ranch and minimal-traditional houses, and over the decades a front door can pass through several owners, contractors, relatives, house sitters, and neighbors who each had a key at some point. Nobody can say how many copies exist. Rekeying answers that question cleanly.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile, so there is no storefront to visit. We bring the tools and key stock to you, work at your door, and hand you working keys before we leave.

How it works in Mission Hills

  1. 1

    Call and describe the job

    Phone (323) 997-8867 any time, day or night. Tell us how many exterior doors and other locks you have, whether you want them all keyed alike, and whether anything looks worn or damaged. That lets us bring the right cylinders and parts.

  2. 2

    Inspect each lock on site

    Before rekeying, we look at every lock for wear, loose fit, sticking, and brand. Older mid-century cylinders and the occasional mortise lockset sometimes cannot be rekeyed reliably, and we tell you plainly if one needs repair or replacement.

  3. 3

    Rekey the cylinders

    We remove each cylinder, replace its pins to match a new key cut, and reassemble it. Where it makes sense, we key front, back, garage-entry, and side doors alike so you carry a single key.

  4. 4

    Test every key and lock

    We operate each lock repeatedly with the new keys, check that the bolt throws fully into the strike, and confirm the old keys no longer turn anything. Doors that rub or do not latch cleanly are flagged before we leave.

  5. 5

    Add upgrades if you want them

    If a door has no deadbolt, or the existing one is low quality, we can add or replace one with a graded deadbolt. For commercial clients, we can also set up a simple master-key arrangement so a manager can open everything while staff keys open only their areas.

  6. 6

    Hand over keys and notes

    You receive your new keys and a clear explanation of what was changed. We recommend keeping a record of who holds copies, so the next change is easy to manage.

What affects the price

  • The number of locks or cylinders being rekeyed, since each one is disassembled and re-pinned individually.
  • Whether you want all locks keyed alike or separate keys for different doors.
  • The condition and type of existing hardware; worn cylinders or older mortise locksets may need repair or replacement rather than a straightforward rekey.
  • Whether you add a new deadbolt or upgrade to a higher security grade.
  • Commercial needs such as master-key systems, which involve more planning and more key combinations.
  • The time of day and the urgency of the request, since we are available around the clock.

Why Mission Hills chooses us

  • Fully mobile service: we work at your door, so there is no shop trip and no leaving a house unsecured.
  • In business since 1987 under owner and lead tech David Shar, with decades of experience on mid-century residential hardware.
  • We tell you honestly when a lock should be repaired or replaced instead of rekeyed, rather than pushing the larger job.
  • Careful handling of vintage doors and hardware, aiming to avoid unnecessary drilling or cosmetic damage.
  • One visit can cover residential rekeying, deadbolt additions, and light commercial master-key setup.
  • Available 24/7, which suits move-in days, closings, and urgent staff changes.

Lock Rekeying across Mission Hills

Mission Hills sits in the northeast San Fernando Valley, and its character shapes the rekey work we do. Around the Historic Mission district, near Mission San Fernando Rey de Espana and the Andres Pico Adobe, quieter streets hold older homes where original hardware is still common. Some of these have aging cylinder locks or mortise locksets that need a gentle approach. We aim to keep the vintage look of a door intact while still giving you modern key control.

In Dennis Park, a historic tract of 1950s ranch homes, a typical job is a resale rekey: all exterior cylinders keyed alike, plus a new graded deadbolt on a door that lacked one. The same goes for streets throughout ZIP code 91345, where buyers often want to know that no previous owner, contractor, or tenant can still let themselves in.

Along the Sepulveda Boulevard corridor and near Providence Holy Cross Medical Center, small medical and professional offices have different needs. After staff changes, a commercial rekey and a simple master-key setup restore control without replacing every lock. We reach customers from San Fernando Mission Boulevard and Brand Boulevard to CA-118 (Ronald Reagan Fwy) and beyond, all by mobile service.

Lock Rekeying in Mission Hills — FAQs

What is the difference between rekeying and changing locks in Mission Hills?
Rekeying changes the internal pins so a new key works and old keys do not, while keeping the same lock hardware. Replacing swaps the whole lock. Rekeying is usually the more economical choice when your locks are in good condition. Call (323) 997-8867 and we can advise on your doors.
Should I rekey after buying a home near the Mission?
Yes, it is a smart first step. You cannot know how many copies of the old keys exist among previous owners, agents, contractors, and neighbors. Rekeying all exterior locks makes sure only the keys you hold will work.
Can you rekey the older locks in a 1950s ranch home?
Often yes, but we inspect first. Many mid-century cylinders rekey well, while badly worn ones may not hold a new pin setup reliably. If that happens, we explain the options, such as repair or replacing that lock.
Can you rekey a mortise lockset on a vintage door?
In many cases, yes. A mortise lockset has a cylinder that can usually be rekeyed. If the lockset itself is failing, we discuss repairing it or upgrading it in a way that respects the original door and avoids unnecessary damage.
Can all my doors work with one key?
Yes. We can key front, back, side, and garage-entry locks alike, provided the cylinders are compatible. If a particular lock cannot be matched, we will tell you and suggest an alternative.
Do you handle rekeying for offices near Providence Holy Cross Medical Center?
Yes. We do commercial rekeys and simple master-key setups for small medical and professional offices, especially after staff changes. Call (323) 997-8867 to describe how many doors and key levels you need.
Is there a shop I can visit?
No. Crenshaw Lock Company is fully mobile. We come to your Mission Hills home or business, 24/7, and do the work on site.
Will the old keys definitely stop working?
Yes. Once a cylinder is rekeyed, the old key will no longer turn it. We test this at the end of the job so you can see it for yourself.
