We’ve been serving Brentwood since before the 2000s housing boom filled the landscape with stucco subdivisions, and we know the hardware inside them. Our Lock Installation & Rekey team covers all of 94513, from the newer master-planned communities off Balfour Road to the established 55+ neighborhoods near Brentwood Boulevard. Summer response times to Brentwood average under 45 minutes because we keep parts stock positioned for this market specifically.
Why Strongbox Lock & Safe Co. Is Brentwood’s Preferred Lock Installation & Rekey Company
Brentwood homeowners call us back because we quote the full price on the phone and it matches the invoice exactly. After 42 years in this region, we’ve rekeyed enough homes in Shadow Lakes, Deer Ridge, and the Summerset communities to recognize the hardware before we pull into the driveway. That familiarity saves you time and us a trip back to the warehouse.
Our reviews from Brentwood customers consistently mention two things: technicians who show ID at the door in uniform, and the 90-Day Done Right Promise that means if something isn’t right, we come back with no paperwork to file and no argument to have. One recent caller from Brentwood Estates told us she’d used three different locksmiths in five years before finding a company that answered the phone at 8 p.m. on a Sunday. We answered. We always do - live person, 24/7, including holidays.
Our flat-price model was built for customers who have been burned by the $19-ad bait-and-switch. The price we quote is the price you pay. That’s the square deal.
Our Lock Installation & Rekey Services in Brentwood
Smart Lock Installation
Smart locks make particular sense for Brentwood’s seasonal residents who leave homes empty for months at a stretch. We install Schlage Encode and Yale Assure models that let you check lock status from anywhere, grant temporary codes to house-sitters or contractors, and receive alerts if someone attempts entry. For the stucco tract homes that dominate Brentwood, we verify Wi-Fi signal strength at the door before recommending a model - thick stucco and metal lath can interfere with wireless connectivity in ways you won’t encounter in older wood-frame construction.
Installation typically takes 45-90 minutes, and we always preserve your existing deadbolt bore so the door integrity stays intact. Summer installations in Brentwood require extra attention: we check that the smart lock’s motorized bolt throw won’t bind when the door frame expands in 105°F heat.
Keyless Entry & Keypad Lock Installation
Keypad locks eliminate the key entirely - a practical upgrade for Brentwood’s 55+ communities where residents have managed physical keys for decades and are ready for something simpler. We install Kwikset SmartCode and Schlage keypad deadbolts that withstand the inland heat better than budget electronic models.
In Summerset and similar older communities, we frequently retrofit keypad locks onto aluminum-frame screen doors that have carried worn Kwikset knobsets since the 1990s. The dry Delta winds that eroded those original locks for 25-plus years demand weather-resistant hardware with sealed electronics. We specify IP-rated keypads for these applications, not the entry-level models that fail within two seasons of Delta exposure.
Biometric Lock Installation
Biometric locks - fingerprint readers - appeal to Brentwood homeowners who want entry without codes to remember or keys to carry. We install commercial-grade biometric deadbolts from trusted manufacturers, not the consumer-grade units that struggle with sweaty fingers after a round of golf at Shadow Lakes Golf Club or summer heat that leaves residue on the scanner.
These installations require precise door prep in Brentwood’s uniform tract homes, where the Kwikset 660 or Schlage B60 bore pattern is nearly universal. We match the new hardware to existing prep to avoid widening holes in doors that were mass-produced during the development rush.
Electronic Lock & Key Duplication
Electronic locks encompass everything from simple push-button models to full access-control systems. For Brentwood’s larger homes with side-entry garages, pool gates, or casita entrances, we install coordinated electronic locksets that operate on a single master code system.
Key duplication remains a steady need in Brentwood, especially for adult children of aging parents in the 55+ communities who need emergency access. We duplicate standard Kwikset and Schlage keys on-site, and we stock high-security Medeco and Mul-T-Lock blanks for homeowners who have upgraded beyond builder-grade hardware.

Trusted Brands We Service in Brentwood
We install and service Schlage, Kwikset, Medeco, and Yale - brands we’ve stocked for decades and know down to the pinning charts. For Brentwood customers, this means no waiting for special-order parts while your front door sits unsecured. Our warehouse carries Schlage B60 deadbolts and Kwikset SmartCode keypads in quantity because we know the demand patterns in this market. When your west-facing door seizes in August heat, we replace it with hardware rated for thermal cycling, not whatever happened to be on the truck that morning.
Common Lock Installation & Rekey Problems We See in Brentwood Homes
- Thermal seizure on west- and south-facing doors. Brentwood’s 103-108°F summer highs expand stucco door frames enough to bind deadbolts against strike plates. We realign or replace strike plates with oversized models that accommodate seasonal movement.
- Worn Kwikset knobsets on aluminum-screen doors in 55+ communities. Summerset I-IV homes still carry original hardware that Delta winds have eroded for 25-plus years. The internal wafers corrode and the springs fatigue - replacement with weather-resistant grade is the only lasting fix.
- Misaligned deadbolts in 2000s tract homes. The uniform housing stock means we see the same installation defects repeated: doors hung slightly out of plumb during mass construction, deadbolts that engage only partially, strike plates secured with short screws that pull free. We correct the root cause, not just the symptom.
- Rekeying after real estate transactions. Brentwood’s active resale market in master-planned communities generates steady rekey demand. We rekey entire homes to a single key, including garage service doors and side gates, in one visit.

Last summer, we rekeyed a home in Summerset II where the original Kwikset 660 deadbolt on a west-facing door had thermally seized from 105°F heat. We replaced it with a Schlage B60 with a backup keypad, ensuring the seasonal owner could enter remotely after months away.

FAQs - Lock Installation & Rekey in Brentwood
Your stucco door frame expands in 105°F heat and compresses the deadbolt against the strike plate. This is a defining seasonal issue in Brentwood’s inland climate, far more common here than in coastal Contra Costa cities where temperatures stay moderate. We install oversized strike plates or adjust frame alignment to accommodate thermal movement. Call (877) 664-8139 for a free assessment - the fix usually takes under an hour.
Yes, we regularly retrofit keypad deadbolts onto aluminum-frame screen doors in Summerset I-IV and similar 55+ communities. The original Kwikset knobsets on these doors have been degraded by Delta wind erosion for 25-plus years, so we specify weather-resistant electronic hardware with sealed components rated for exposed installation. Not every keypad lock survives this environment - we know which ones do. Call for a flat quote on your specific door.
They were adequate when installed but are now reaching the 15-20 year failure threshold simultaneously across Brentwood’s uniform housing stock. The Kwikset 660 deadbolts common in 2002 construction offer basic security; upgrading to a Schlage B60 (Grade 2) or adding a keypad layer provides meaningful improvement without replacing the door. We can rekey your existing hardware for immediate security, then discuss upgrade options. Free estimates: (877) 664-8139.
A Wi-Fi smart lock with remote monitoring and temporary code management is the most practical solution for seasonal absence. We install Schlage Encode and Yale Assure models that alert you to any entry attempt, let you verify the lock remotely, and eliminate the risk of hidden keys. For Brentwood’s summer heat, we verify thermal tolerance and Wi-Fi connectivity at your specific door before recommending a model. Call for a flat-installed price.
A standard 3-4 door Brentwood tract home runs $120-$220 to rekey entirely to a single key. Most 2000s-era homes here have identical Kwikset or Schlage hardware, which keeps the job straightforward. Adding garage service doors, side gates, or a storage shed typically adds $25-$45 per cylinder. We quote the full price on the phone - call (877) 664-8139 and count your lock cylinders for an exact figure. Estimates are free.
