Rekeying is the quickest way to take back control of who can open your door. Instead of replacing the hardware, we change the internal pin configuration of the lock cylinder so that the old keys no longer turn it, and a new key does. The lock, deadbolt and handle you already own stay on the door. It suits many Rosemead situations: you just bought a house off Rosemead Boulevard, a tenant has moved out of a garage conversion, or a former employee still carries a key to your shop.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile, so there is no storefront to visit. Our technicians bring the tools and key blanks to your property, and we work around the day or night you need us.

Rosemead has a mix of properties where this matters. Many of the 1950s and 1960s single-story stucco and ranch homes have changed hands several times, and a lot of them now have converted garages, ADUs or multi-family additions, each with its own locks and its own set of keys floating around. Along Valley Boulevard and Garvey Avenue, aluminum-storefront markets and restaurants have staff turnover that makes key control a real concern. Rekeying handles all of these without the cost and waste of a full lock replacement.

How it works in Rosemead

  1. 1

    Call and describe the property

    Call (323) 997-8867 any hour. Tell us whether it is a house, ADU, apartment building or business, how many locks are involved, and what brand they are if you know. That helps us bring the right pinning kits and key blanks.

  2. 2

    We come to you

    Because we are fully mobile, a technician drives to your Rosemead address with the equipment needed. We do not make any promises about arrival times, but we do operate around the clock.

  3. 3

    Inspect each lock

    Before any work, we check that every cylinder is in good working order. Rekeying only makes sense on locks that still function well. If a deadbolt is worn, loose or damaged, we say so honestly and explain the options, including replacement.

  4. 4

    Rekey the cylinders

    We remove the cylinder, replace its internal pins to a new combination, and reassemble it. The old key will no longer turn the lock. Where you want it, we can key several locks on a property to one new key so you carry just one.

  5. 5

    Test and hand over keys

    We test every lock with the new key, confirm the old key fails, and check that doors latch and lock smoothly. Then we give you the new keys and can cut extra copies for family members, tenants or staff.

  6. 6

    Advice on follow-up security

    If we notice weak strike plates, short screws, or a garage-conversion door with poor hardware, we point it out. Any additional work is your decision.

What affects the price

  • The number of cylinders: one front door lock costs less to handle than a whole house, a multi-unit building, or a storefront with several entrances.
  • Lock brand and type: standard residential deadbolts, high-security cylinders, and commercial aluminum-storefront locks all differ in the parts and effort involved.
  • Condition of the existing hardware: a worn or damaged lock may need repair or replacement instead of a simple rekey.
  • Number of keys needed: extra copies, or master-keying across several units, add to the work.
  • Time and location of the call: after-hours and emergency visits are handled differently than scheduled daytime appointments.
  • Scope of the job: a bulk rekey for a property manager after an ownership change is scoped differently than a single-door service.

Why Rosemead chooses us

  • Fully mobile service: we bring everything to the property rather than asking you to drop off locks, and there is no storefront to visit.
  • In business since 1987, with owner and lead technician David Shar involved in the work.
  • Honest recommendations: if a lock is too worn to rekey, we tell you instead of selling a rekey that will not last.
  • Experience with both homes and businesses, from ranch-style houses and ADUs to storefront markets and restaurants.
  • Multi-unit capability: we can rekey several apartments in one visit and organize keys by unit for property managers.
  • Available 24/7, so you can secure a property the same day you take possession or when a lease ends.

Lock Rekeying across Rosemead

Rosemead is a dense valley-floor city, and rekeying needs differ by neighborhood. In North Rosemead and South Rosemead, much of the housing is 1950s and 1960s single-story stucco and ranch homes. Buyers often want every lock rekeyed on closing day, and landlords commonly turn over a house or a garage-conversion ADU between tenants. A typical ZIP 91770 home may have a front deadbolt, a back door, a side gate and a converted garage entry, and all of them can be keyed alike.

The Garvey district and the Valley Boulevard and Garvey Avenue corridors are heavily commercial, with aluminum-storefront retail strips, markets and restaurants. When a manager or employee leaves, rekeying the storefront cylinder is a faster and cheaper way to restore key control than replacing every door's hardware. We also service properties in ZIP 91771 and 91772, and the apartment complexes around the city where a property manager may need several units done after an ownership change.

We reach customers near I-10, Rosemead Boulevard (SR-19), San Gabriel Boulevard, Garvey Park, Rosemead Place and the Southern California Edison headquarters campus, as well as areas next to Whittier Narrows Recreation Area. We are mobile only, so we come to wherever you are in Rosemead.

Lock Rekeying in Rosemead — FAQs

What is the difference between rekeying and changing locks in Rosemead?
Rekeying changes the inside of the cylinder so a new key works and old keys do not, while the hardware stays on the door. Changing locks replaces the hardware itself. Rekeying is usually the better fit when your locks are in good shape. Call (323) 997-8867 and we can advise.
Should I rekey after buying a home in Rosemead?
Yes, it is a sensible step. You can't know how many copies of the old keys exist among previous owners, tenants, agents and contractors. Rekeying makes sure only the keys you hold will work.
Can you rekey a garage conversion or ADU separately?
Yes. Many Rosemead properties have a converted garage or ADU with its own entry. We can rekey it on its own key or match it to the main house, depending on how you want access arranged.
Can you rekey several apartment units at once?
Yes. For property managers after an ownership change, we can rekey multiple units in one visit and organize the keys by unit. Call (323) 997-8867 to talk through the number of units and lock types.
Can you rekey a storefront lock on Valley Boulevard or Garvey Avenue?
Yes, we work on commercial cylinders in aluminum-storefront doors. If an employee has left or keys have been lost, rekeying the cylinders restores control without replacing the whole door setup.
Are you available at night or on weekends?
Yes. We are available 24/7 and fully mobile. Call (323) 997-8867 at any hour and we will come to you.
Will my old keys still work after rekeying?
No. Once a lock is rekeyed, the old key will not turn it. We test this at the end of each job so you can see it for yourself.
Do I need to be home during the rekey?
Someone authorized should be present, or have arranged access, so we can reach the locks and hand over the new keys. For vacant rentals, talk to us when you call about how to coordinate.
