Rekeying is one of the most practical security upgrades you can make, and it is often misunderstood. Instead of tearing out a good deadbolt, we alter the pin configuration inside the cylinder so it responds to a new key. The lock looks the same, the door is untouched, and every key that used to open it becomes useless. In Monterey Park, where so many homes change hands, get rented out, or pass between family members, that matters.
The most common reasons people call us are simple: you just bought a home and have no idea how many copies of the keys are floating around, a tenant or student moved out, an employee left a restaurant or office, or a key was lost. Rekeying answers all of these for much less disruption than a full replacement, and we can usually do every lock on a property in a single visit so they all work with one key.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, under owner and lead technician David Shar. We are fully mobile, with no storefront to visit. We come to you with the tools and key blanks needed to do the work on site, day or night.
How it works in Monterey Park
- 1
Call and describe the locks
Phone us at (323) 997-8867 and tell us what you have: how many doors, what kind of locks (standard deadbolts, knobs, smart deadbolts, storefront cylinders), and why you want them rekeyed. That helps us bring the right pinning kits and key blanks.
- 2
We come to you
As a fully mobile service, we travel to your home, apartment building, or business in Monterey Park. We are available 24/7, so a rekey after a break-in scare or a late move-out does not have to wait for business hours.
- 3
Inspect each lock
Before touching anything, we check that each cylinder is in good working condition. Rekeying only makes sense if the lock is sound. If a deadbolt is worn, damaged, or seized, we will tell you honestly and explain whether repair or replacement is the better route.
- 4
Remove and re-pin the cylinders
We take the cylinder out, remove the old pins, and install a new pin combination matched to a new key. Where it makes sense, we key several locks alike so you carry one key for the front door, back door, and garage entry.
- 5
Cut keys and test everything
We cut the new keys, reinstall the cylinders, and test each lock repeatedly with the new key. We also confirm the old key no longer turns, so you know the rekey did its job.
- 6
Review and next steps
We hand over the keys and talk through anything else worth addressing, such as a worn strike plate, a loose deadbolt, or reprogramming a smart lock's codes after the cylinder work.

What affects the price
- The number of locks or cylinders being rekeyed, since each one is taken apart and re-pinned individually.
- The type of hardware: standard residential deadbolts differ from smart deadbolts, commercial storefront cylinders, or mailbox locks.
- Whether you want all locks keyed alike or separate keys for different doors and users.
- How many new keys you need cut, which matters for families, landlords, and businesses with several staff.
- The condition of the existing locks, because worn or damaged hardware may need repair or replacement instead of a simple rekey.
- The time of day and urgency of the request, since after-hours and same-night service involve different scheduling than a planned daytime visit.
Why Monterey Park chooses us
- We have been serving Greater Los Angeles and Ventura County since 1987, so rekeying a mid-century stucco home or an aluminum storefront is familiar work.
- Fully mobile and available 24/7, with nothing to drive to: we do the work at your door.
- Honest assessments: if a lock should be replaced rather than rekeyed, we say so instead of upselling.
- Comfortable with both traditional deadbolts and the electronic or smart deadbolts increasingly common in hillside homes.
- Experienced with multi-unit work for landlords, including keying units alike or separately and handling mailbox locks during turnovers.
- One owner-led operation under David Shar, so the standards on your job are the same as on every other.
Lock Rekeying across Monterey Park
Monterey Park has a real mix of housing, and rekeying needs vary with it. In the hillside neighborhoods like Monterey Highlands and the Midwick-adjacent slopes, many single-family homes date to the 1950s and 60s, and more owners are adding electronic deadbolts. When a home changes hands in ZIP code 91754, rekeying the existing locks and reprogramming any smart lock codes is a smart first step. Below the hills, the flats near the East LA border and around Garvey Ranch have stucco houses, apartments, and condos where landlords and families often want a clean key reset.
Rental turnover is a steady reason for calls. A landlord with a mid-century apartment building near East Los Angeles College, for example, may need several units rekeyed between tenants, along with new mailbox locks, so a departing student's keys stop working. Doing it all in one visit keeps units ready for the next move-in. Homeowners near Barnes Memorial Park, Edison Trails Park, or the Garvey Ranch Observatory in ZIP code 91755 often ask us to rekey after buying, renovating, or losing a key.
Businesses along Atlantic Blvd and Garvey Ave also rely on rekeying. Restaurants, markets, and offices there often have aluminum-storefront deadbolts, roll gates, and exit hardware, and a staff change or a lost key means the locks should be reset. We can work after hours so you do not lose service time. Whether you are off I-10, SR-60, or Garfield Ave, we come to you at (323) 997-8867.
