Sargent Residential Locksmith in Fort Worth: What to Know First
We provide independent Sargent residential locksmith service across Fort Worth, typically arriving within 30-45 minutes for lockouts and scheduling rekeys and installations within 24-48 hours. Every Sargent job starts with a written price quoted on the phone, and that price is contractually the price on the invoice - Haven Standard Clause 1, in force since 2002. This page is for Fort Worth homeowners who need Sargent lock repair, rekeying, replacement, or door reinforcement and want to know what the work actually costs and what a technician should look for before touching the hardware. Call (817) 765-4998 for a written estimate with no dispatch fee.
How Sargent Products Fail - and How We Fix Them
We’ve worked on Sargent hardware in Fort Worth homes from the 1980s ranch houses off Camp Bowie Boulevard to newer builds in the Cultural District. These are the failure patterns we see:
- Sargent 8200 Series mortise locks: latchbolt sag and faceplate misalignment. The heavy brass construction outlasts the door itself, but the latchbolt wears an oval path into the strike plate after years of Fort Worth’s humidity swings expanding and contracting the jamb. We measure the wear pattern, shim or replace the strike, and either reset the lock case or replace the worn latch assembly. OEM Sargent parts are still available; we quote both OEM and Grade 1 aftermarket options in writing.
- Sargent 10-Line cylindrical leversets: spindle cam fracture. The split-spindle design transmits torque directly to the cam, and after roughly 15-20 years of daily cycling the zinc die-cast cam cracks without warning. The symptom is a lever that spins freely with no latch retraction. We stock the Sargent 13-0420 cam and can replace it in the field, or upgrade to a solid-steel aftermarket cam on request.
- Sargent 11-Line residential deadbolts: cylinder rotation without bolt throw. The tailpiece connection to the bolt mechanism strips, usually because the cylinder was overtightened during a previous installation or rekey. We disassemble the housing, inspect the tailpiece slot for wallowing, and replace the bolt assembly if the cam slot is elongated. This is a warranty-safe repair; drilling the cylinder voids Sargent’s limited warranty, so we never do it.
- Sargent 7-Line entry sets: finish degradation on coastal-import batches. Certain 2012-2016 production runs with PVD satin nickel finish developed peeling at the lever grip, particularly on south-facing doors in Fort Worth’s UV exposure. The lock mechanism remains sound. We can replace levers with matching finish-correct OEM parts or convert to a different Sargent line if the homeowner is already planning a hardware refresh.
- Sargent 60-Series auxiliary deadbolts: incorrect backset on retrofit installs. These were popular add-ons in 1990s Fort Worth renovations, but installers often drilled 2-3/8″ backset holes into doors that needed 2-3/4″. The bolt binds, the keyway stresses, and eventually the cylinder twists in the housing. We assess the door prep, relocate to correct backset if the door integrity allows, or specify a properly sized replacement with written measurements before cutting.
Our Sargent Residential Locksmith Process

- 1
Call intake and photo request. We ask for clear photos of the lock face, any visible model stamping, and the door edge. This lets our dispatcher identify the Sargent series and quote parts availability before we leave the shop.
- 2
On-site diagnostics with written scope. The technician documents the lock condition, door prep, and any security gaps - for example, a Sargent deadbolt paired with a hollow-core door or a missing strike-box. You receive a written scope with part numbers, labor line items, and total before any work begins.
- 3
Parts decision: OEM Sargent or quality aftermarket. We stock common Sargent cylinders, cams, and latchbolts. If OEM lead time exceeds your timeline, we present an aftermarket equivalent that meets ANSI Grade 1 or 2 specifications, with the tradeoff explained in writing.
- 4
Repair or replacement to The Haven Standard. Work is performed with non-destructive methods where possible. Cylinders are rekeyed on-site with factory-original pinning kits. Installations include strike-box reinforcement and three-point latch testing.
- 5
Documentation and test. We cycle the lock 25 times, test key operation from both sides, and photograph the completed work. The photo record and written warranty are left with you; a copy is archived under your address in our system.
- 6
365-Day Done Right Promise activation. If the latch sticks, the key binds, or any aspect of the work fails to perform as specified, we return and make it right. Haven Standard Clause 7.
What Sargent Residential Locksmith Costs in Fort Worth
These are the price ranges we quote in writing for typical Sargent residential work in the Fort Worth market. Final cost depends on parts grade, door condition, and whether the existing prep is standard or requires modification.
- Sargent lock rekey (per cylinder): $28-$45
- Sargent cylindrical lock repair (cam, latch, or cylinder replacement): $145-$280
- Sargent mortise lock repair (8200 series): $220-$395
- Sargent deadbolt installation (new prep, standard door): $185-$295
- Sargent deadbolt installation (door reinforcement or non-standard prep): $295-$450
- Sargent lever or knob replacement (retrofit to existing prep): $165-$275
- Residential lockout service (Sargent hardware): $95-$145
- Strike plate / jamb reinforcement: $75-$140
Factors that move the price: mortise lockcases with stripped mounting threads requiring helicoil repair; doors with multiple layers of old hardware needing fill and re-drill; high-security cylinder upgrades (Medeco, Mul-T-Lock) in Sargent housings. We state all of this on the phone. There is no call-out surcharge, no trip fee, and no after-hours premium for standard Sargent service calls. The price quoted is the price on the invoice - Clause 1.

FAQs
No, provided the repair is performed without drilling the cylinder or modifying the lockcase in ways not specified by Sargent. We use factory-original parts and document the work, which preserves warranty coverage on any remaining components. If your lock is still under Sargent’s limited lifetime warranty, we note the serial number and provide a copy of our invoice for any future claim you may file directly with the manufacturer.
Yes, for most residential Sargent series produced after 1980. We maintain relationships with legacy parts suppliers and can often source NOS (new old stock) cams, cylinders, and trim for 8200, 10-Line, and 7-Line hardware. If a part is truly obsolete, we specify a dimensionally compatible replacement and show you the fit in writing before installation.
Repair makes sense when the lockcase is sound and the failure is isolated to a cam, cylinder, or latchbolt - typically $145-$280 versus $185-$450 for full replacement. Replace when the lockcase is cracked, the door prep is compromised, or you are upgrading security grade. We assess both paths on-site and quote each in writing so you can compare.
Lockout response is typically 30-45 minutes across Fort Worth, including the Near Southside, Arlington Heights, and Ridglea areas. Scheduled rekeys and non-urgent repairs are usually set within 24-48 hours. Same-day scheduling is often available for calls received before 2 PM. Call (817) 765-4998 for current availability and a written estimate.
We service Sargent KP-Series and certain Passport 1000 standalone electronic locks for residential applications. Full networked access control falls outside our residential scope; we refer those jobs to commercial specialists and can rekey the mechanical override cylinders before handoff. We will tell you directly if your Sargent hardware is outside our service range.
