Rekeying is the quiet fix that most people overlook after a move. Instead of replacing a lock, we alter the pins inside the cylinder so it works with a new key and the old keys become useless. You keep the hardware you already have, and anyone who held a copy of the previous key, such as past owners, tenants, contractors or a former roommate, no longer has access.
In South Pasadena this matters more than in most places. Much of the city is made up of well-preserved Craftsman bungalows, Victorians and 1920s Spanish and period-revival homes, and many still wear their original rim and mortise hardware. That hardware is part of the home's character, and often part of its value. Rekeying lets you secure the house without swapping out a period lockset that would be hard to replace.
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, with no storefront to visit. We come to you, whether that is a bungalow off Fremont Ave or a shop on Mission Street, and we are available around the clock.
How it works in South Pasadena
- 1
Call and describe the locks
Call (323) 997-8867 and tell us what you have: front door, back door, side gates, garage entry, or a shop door. Mention whether the hardware looks original, such as a mortise lock or a rim cylinder, so we bring the right tools and parts.
- 2
We come to you
Our technician arrives in a fully equipped mobile service vehicle. Because we work on site, you do not need to remove any locks or bring anything anywhere. We confirm what is being rekeyed before work begins.
- 3
Inspect each cylinder
We check each lock for wear, brand and condition. Older cylinders sometimes have worn pins or stiff springs, and we tell you plainly if a lock is better rekeyed, repaired or, only when necessary, replaced.
- 4
Rekey to a new key pattern
We remove the cylinder, replace the pins to match a new key, and reinstall it. Vintage faceplates, knobs and escutcheons stay in place, so the look of the door does not change. We can key several doors alike so you carry a single key.
- 5
Test and hand over keys
We test every lock with the new keys and confirm the old keys no longer turn. You get your new keys and a clear rundown of what was done.

What affects the price
- The number of cylinders being rekeyed, since each door, gate and padlock adds work.
- The type of hardware: standard deadbolts are generally quicker than older mortise sets or specialty cylinders.
- Whether you want all locks keyed alike or want separate keys for different doors or users.
- The condition of the existing locks, including whether worn parts need repair before they can be rekeyed reliably.
- The time of day and urgency of the visit, since we work 24/7 and after-hours calls differ from scheduled daytime appointments.
- How many keys you need cut, and whether any restricted or high-security keyways are involved.
Why South Pasadena chooses us
- Fully mobile service: we bring the tools and parts to your door, with no shop visit and no need to remove hardware.
- Experience with older hardware: we have worked on rim and mortise locks like those found in Craftsman bungalows and period-revival homes since 1987.
- Preservation first: we aim to keep original knobs, plates and finishes intact rather than push unnecessary replacements.
- Discretion for film-location homes: we handle rekeys and temporary lockboxes quietly, which suits owners who host productions.
- Honest recommendations: if a lock is too worn to rekey well, we say so and explain your options.
- Available 24/7, so a lost key or a late closing on a sale does not have to wait until morning.
Lock Rekeying across South Pasadena
South Pasadena is compact, only about 3.4 square miles, but its housing mix is varied. In the Mission Street District, the 91030 ZIP code covers Craftsman homes and small commercial storefronts. A common call is a buyer who has just closed escrow and wants every old key rendered useless, while keeping the home's original rim and mortise hardware.
Up in Monterey Hills and Altos de Monterey, homes are often hillside properties with multiple entries, side gates and garage doors. Rekeying them to a single key is popular, and ZIP code 91031 includes many such streets. Owners tell us they like not juggling a ring of mismatched keys.
The city is also a frequent film and TV location. For homeowners with a frequently filmed bungalow, we can install a temporary contractor lockbox during a production and then rekey after the crew wraps so access is reset. On Mission Street, near Mission West antique row and the Rialto Theatre, shop and restaurant owners with older commercial locks also call us when the only set of keys goes missing mid-shift. Wherever you are, from Fair Oaks Ave to Garfield Park, we come to you.
