Rekeying is the quiet fix that solves a loud problem: you don't know who still holds a key to your door. Maybe you just closed on a house near Citrus College, inherited a set of keys from a former tenant, or ended a roommate arrangement on a bad note. Instead of tearing out perfectly good hardware, we change the internal pin configuration of each cylinder so the old keys stop working and a new key takes over.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no storefront to drive to. Our tech brings the tools, key blanks, and replacement parts to your door in Glendora, whether that's a tract home in South Glendora, a boutique space in Glendora Village, or a custom home up in the foothills. Owner and lead tech David Shar built the business on explaining options plainly, so you know what is being done and why.
Rekeying is not always the right answer, and we'll say so. If a lock is worn, damaged, or the wrong grade for the door, replacing it may serve you better. Part of every visit is a quick look at the condition of your hardware so the choice between rekeying and replacing is an informed one, not a sales pitch.
How it works in Glendora
- 1
Call and describe your locks
Phone (323) 997-8867 any hour. Tell us how many doors, what brands you have, and why you want to rekey, such as a move, a sale, or a lost key. That helps us bring the right pinning kits and parts.
- 2
We come to you
Because we are fully mobile, the work happens at your property. We confirm who is authorized to request the rekey before starting, since changing locks is a security-sensitive job.
- 3
Inspect each lock
Before disassembling anything, we check that each cylinder turns smoothly, the latch and strike line up, and the hardware is in good enough shape to be worth rekeying. Worn or damaged locks get flagged.
- 4
Rekey the cylinders
We remove each cylinder, replace the pins to match a new key cut, and reassemble. Entry doors, deadbolts, and often side gates, garage entry doors, and patio doors can be set to work with one key.
- 5
Test every key and lock
We try the new key in every lock several times, confirm the old key no longer operates, and check that doors latch and deadbolts throw fully.
- 6
Hand over keys and next steps
You get your new keys and straight advice on spare copies, plus a note on any hardware that deserves an upgrade later. Nothing is replaced without your say-so.

What affects the price
- How many cylinders are being rekeyed, since each lock is its own piece of work
- The brand and type of hardware, because standard residential locks, higher-end designer sets, and multipoint systems are handled differently
- Whether any locks are worn, damaged, or gritty enough that cleaning, repair, or replacement is needed alongside the rekey
- Whether you want all locks keyed alike to a single key or separate keys for different doors
- The number of new keys you need cut
- The time of day and the location of the property, since we are available around the clock and travel to you

Lock Rekeying across Glendora
Glendora's housing varies a lot from the foothills down to the flatlands, and rekeying looks different in each. In North Glendora, larger hillside and custom homes, many from the mid-century era, often carry upscale hardware like Baldwin and Emtek sets, multipoint patio doors, and sometimes gated entries or long private drives. Those locks deserve careful handling and the right parts. Homes in the foothill fire zone near Big Dalton Canyon and the trailheads also deal with Santa Ana wind season, which can leave locks fouled with grit and dust. A rekey is a good moment to clean and check a sticky cylinder.
South Glendora is mostly post-war single-family tract housing, where the locks are often original or have passed through several owners. For anyone who recently bought in the 91740 area, rekeying the exterior doors is a sensible first-week task, and it usually costs far less than replacing everything. Near Glendora Village, with its early-1900s buildings and boutique storefronts, older doors and mixed hardware are common, and we can look at what's there before recommending anything.
Whether you're off Grand Ave, Glendora Ave, or Lone Hill Ave, or closer to Foothill Blvd and the Route 66 corridor, or in the 91741 ZIP code up toward the hills, we come to you. Residents near Citrus College and the Glendora Country Club call us for move-ins, tenant turnovers, and lost-key situations. Call (323) 997-8867 and we'll schedule a visit.
