Rekeying changes the inside of a lock so that a new key operates it and every old key becomes useless. The lock itself, the handle, and the deadbolt stay on the door. In South El Monte, that makes it a practical choice in two very different settings: the modest post-war houses and small apartment buildings away from the industrial corridors, and the tilt-up warehouses, small factories, and manufacturing yards that cover so much of the city.

People usually call us for rekeying after a move or a home purchase, when nobody can say how many copies of the old keys exist. Others call after a tenant leaves, after an employee departs, or after a key goes missing. Business owners near Rush Street and Santa Anita Ave often have a mix of commercial cylinders, man-door locks, roll-up door locks, and padlocks. Over the years keys for those get handed to drivers, temps, and contractors, and rekeying brings them back under one controlled set.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and our owner and lead technician, David Shar, built the business around mobile service. We are fully mobile and available around the clock, so the work happens at your door, on your schedule, whether that is a weekday afternoon or after a shift ends.

How it works in South El Monte

  1. 1

    Tell us what needs rekeying

    Call (323) 997-8867 and describe the locks: front and back doors, a garage side door, a factory man-door, a roll-up door, or padlocks. Tell us whether you want everything on one key. That helps us bring the right pinning kits and parts.

  2. 2

    We come to you

    Because we are fully mobile, a technician travels to your home, apartment building, or industrial yard in South El Monte. There is no shop to visit and nothing to drop off. We work on the locks where they are installed.

  3. 3

    Inspect each lock

    Before we change anything, we check that each lock works smoothly and is worth rekeying. Worn cylinders, damaged deadbolts, or a hasp that is failing may be better replaced, and we will explain the difference plainly so you can decide.

  4. 4

    Rekey the cylinders

    We remove the cylinder, replace the internal pins to match a new key, and reinstall it. Multiple locks can be set to the same key so you carry one instead of many. Brand-compatible cylinders keep their existing hardware.

  5. 5

    Test and hand over keys

    We try the new keys in every lock, confirm that the old keys no longer turn, and check that doors latch and lock properly. You get the new keys, and we can discuss extra copies or a master key arrangement for a business.

What affects the price

  • How many locks or cylinders need to be rekeyed, since each one is pinned individually
  • The type of lock: standard residential deadbolts differ from commercial cylinders, padlocks, and roll-up door locks
  • Whether you want all locks keyed alike or a more structured system with separate keys and a master
  • Whether any lock is worn or damaged and needs repair or replacement rather than a simple rekey
  • How many extra keys you need cut for family members, employees, or drivers
  • The time of day or night you need us, as after-hours and urgent calls can be priced differently from scheduled visits

Why South El Monte chooses us

  • Fully mobile service: we work at your door in South El Monte, with no storefront trip
  • Available 24/7, so rekeying can fit around shift schedules and move-in dates
  • In business since 1987, with experience across homes, apartments, and commercial and industrial properties
  • Comfortable with both residential deadbolts and heavy-duty industrial hardware like commercial cylinders and roll-up door locks
  • We tell you when replacement makes more sense than rekeying instead of selling you something you do not need
  • Straightforward conversations about cost drivers before work begins, with no invented quotes or pressure

Lock Rekeying across South El Monte

South El Monte is an unusual place for a locksmith because the industrial and residential sides of town call for very different work. Around the Rush Street and Santa Anita industrial district in ZIP code 91733, many buildings are tilt-up warehouses and small factories secured with commercial cylinders, padlock-and-hasp setups, and roll-up door locks. A common request there is to rekey the man-door and roll-up locks on a small factory off Santa Anita Ave, and to swap out a worn padlock for a heavy-duty one after keys have spread among staff and contractors.

The residential streets, mostly post-war single-family homes and small apartment buildings, sit away from those corridors. Many of those homes have changed hands more than once, and their original deadbolts have outlasted several owners. Rekeying is a sensible way to reset who has access without replacing hardware that still works fine. Neighbors near the southern edge of the city by Whittier Narrows, close to the Whittier Narrows Recreation Area and Legg Lake, call us for the same reason after buying or renting a place.

We reach customers via Interstate 10, Rosemead Blvd (SR-19), Santa Anita Ave, Durfee Ave, Peck Rd, and Rush St, and since we are mobile, the job is done wherever your locks are, whether in a yard near the San Gabriel River corridor or on a quiet residential street. Call (323) 997-8867 any hour.

Lock Rekeying in South El Monte — FAQs

What is the difference between rekeying and replacing a lock?
Rekeying changes the internal pins so a new key works and old keys do not, while the lock hardware stays in place. Replacing swaps the whole lock. Rekeying is usually the simpler choice when the lock is in good shape. Call (323) 997-8867 and we can help you decide.
Should I rekey after buying a home in South El Monte?
It is a smart step. You cannot know who still holds copies of the old keys, from previous owners to contractors. Rekeying makes sure only the keys you hold will work.
Can you rekey commercial and industrial locks?
Yes. We work on commercial cylinders, man-door locks, roll-up door locks, and padlock setups common at factories and warehouses near Rush Street and Santa Anita Ave. Describe what you have when you call (323) 997-8867.
Can all my locks be keyed to the same key?
In most cases, yes, as long as the locks are compatible with the keyway we are working with. We can set front, back, and garage locks to one key. Some locks may need replacement to match.
Do I need to come to your shop?
No. We are fully mobile and have no storefront. We come to your home, apartment, or business in South El Monte and do the work on site.
Do you rekey at night or on weekends?
We are available 24/7. If you need locks rekeyed after business hours, call (323) 997-8867 and we will talk through the schedule with you.
Will my old keys still work after rekeying?
No. After rekeying, the old keys will not turn the lock. We test this before we leave, so you can be confident only the new keys have access.
Can a worn or broken lock still be rekeyed?
Sometimes, but not always. If a cylinder or deadbolt is damaged, replacing it may be the more reliable fix. We inspect first and explain your options honestly.
