Sargent Lock Installation & Rekey in Long Beach: What to Know First
We provide independent Sargent lock installation and rekey service across Long Beach, typically scheduling same-day or next-day appointments with a written price quoted before any work begins. Most residential Sargent rekeys run $28-$45 per cylinder, while full lock installation ranges from $140-$320 depending on the series and door prep required. Haven Standard Clause 1 applies: the price we quote on the phone is the price on the invoice, and our technicians are not permitted to change it at your door.
This page is for Sargent owners in Long Beach who need a lock installed, rekeyed, or assessed for replacement. We work with Sargent’s full residential and light-commercial catalog, including the popular Latitude and Traditional lines common in Belmont Shore and Bixby Knolls homes built between 2015 and 2020. If you’re unsure which series you have, the model number is stamped on the latch face or behind the interior escutcheon. Call (424) 340-6795 and we’ll identify it over the phone.
How Sargent Products Fail - and How We Fix Them
- Latitude levers with loose return springs. The Latitude series uses a stamped-steel torsion spring in the chassis that fatigues after roughly 8-12 years of daily use in Long Beach’s coastal humidity. The lever goes slack and won’t return to horizontal. We replace the chassis with an OEM Sargent 28-10U chassis or a Grade 2 equivalent if the customer wants to step up durability. Rekeying at the same time costs less than doing it later.
- 10-Line cylindrical locks with spun cams. The 10-Line is Sargent’s workhorse in light commercial and some high-end residential installs around the Port of Long Beach. The zinc cam at the back of the cylinder strips where it meets the latch actuator, usually because a previous rekey used an incorrect key blank that required excess torque. We bore the cylinder, install a brass replacement cam, and rekey to a factory-spec keyway. Brass cams outlast zinc by a factor of three in our records.
- keypad locks with corroded battery contacts. Sargent’s KP-10 and related electronic locks suffer from green corrosion on the battery contacts within 4-6 years in Long Beach’s salt air, even inland. The lock beeps low-battery with fresh batteries installed. We clean the contacts, apply a dielectric grease rated for marine environments, and test draw current under load. If the board is damaged, we quote a replacement versus a new install.
- Traditional mortise locks with worn hub springs. Older Sargent mortise bodies in Long Beach’s pre-war apartments and commercial buildings develop hub spring fatigue that lets the knob or lever wobble without retracting the latch. The fix is a hub spring kit (Sargent 68-1183 for most 8800-series bodies), not a full lock replacement. We rekey the cylinder while the body is apart, since the labor to disassemble is already spent.
- Grade 1 cylindrical locks with misaligned strikes. Sargent’s 7800 and 8200 series are built tight-tolerance, which means a strike plate even 1/8 inch off-center causes accelerated latch bolt wear and eventual failure to latch. In Long Beach’s hillside homes and post-1980s construction with settling slab foundations, we see this constantly. We relocate or shim the strike, check the door frame with a straightedge, and replace the latch if the nose is already worn concave.
Our Sargent Lock Installation & Rekey Process
- 1
Call and identification. We answer live, 24/7. You describe the lock or send a photo of the latch face or interior cover. We identify the Sargent series, diagnose the likely failure, and quote a firm price range. No dispatch until you agree in writing.
- 2
Parts decision. For rekeys, we stock Sargent LA and LB keyways plus Schlage-compatible interchangeable cores. For repairs, we carry OEM Sargent parts and select Grade 1 aftermarket equivalents where the customer prefers value over brand matching. We state the warranty difference: OEM parts carry Sargent’s limited warranty; our aftermarket carries our 365-Day Done Right Promise.
- 3
On-site verification. The technician confirms the diagnosis, photographs the existing lock condition, and presents the final written scope. The price does not change from the phone quote unless you add work. Haven Standard Clause 1.
- 4
Service execution. Rekeys are done in our van’s keying station or on-site depending on cylinder count. Installations include door prep, strike alignment, and three-point function test: key operation, thumbturn or lever return, and latch engagement depth.
- 5
Documentation and closeout. You receive a photo record of the work, the written invoice with line-item breakdown, and the 365-Day Done Right Promise card. The technician explains each line before you sign. The name on the van is the same name on the invoice. That is the whole argument.

Every visit sends a background-checked, uniformed technician with a documented photo record left in your hands at completion. Calls are answered by a live person, never a queue.

FAQs
No. Rekeying a Sargent cylindrical or mortise lock by a qualified technician does not void the original finish or mechanical warranty, provided no modification is made to the lock body beyond normal pin replacement. We use factory-spec pinning kits and document the key code for your records. If your lock is still under Sargent’s limited lifetime finish warranty, we note the installation date and series on your invoice so you have proof of service. Call (424) 340-6795 if you need help determining warranty status.
Most residential Sargent rekeys are completed in 20-40 minutes on-site, with same-day or next-day scheduling available. Commercial master-key rekeys take longer depending on cylinder count and key hierarchy complexity. We stock common Sargent keyways and pinning kits, so we rarely need to return. For scheduling, call (424) 340-6795.
Repair makes sense when the lock body is sound and the failure is isolated to a spring, cam, or cylinder. Replace when the body is cracked, the finish is degraded beyond cosmetic acceptability, or the series is obsolete and parts are scarce. We assess this on-site, show you the wear, and quote both options in writing. There is no default answer; we report what we find and let you decide.
We stock both and disclose which we are installing before any work starts. OEM Sargent parts carry the manufacturer’s warranty and match original specifications. Our aftermarket equivalents, sourced from reputable manufacturers, carry our 365-Day Done Right Promise and typically cost 15-25% less. For high-security or master-keyed systems, we recommend OEM to maintain keyway integrity.
Only if the Sargent lock is equipped with an interchangeable core or if we convert it to accept a compatible cylinder. Sargent’s standard keyways (LA, LB, LD) are not physically compatible with Schlage SC1 or Kwikset KW1 keyways. We can install a Schlage-compatible SFIC core in some Sargent housings, or replace the cylinder entirely. We explain the security and cost implications in writing before proceeding. Call (424) 340-6795 to discuss your specific setup.
