Sargent Lock Installation & Rekey in Fort Worth: What to Know First
We install and rekey Sargent locks as an independent service provider in Fort Worth, with most residential jobs completed same-day and commercial master-key projects scheduled within 48 hours. A standard Sargent cylindrical rekey runs $28-$45 per cylinder; full lock installation with a new Sargent B-series or 10-line bored lock typically falls between $140-$280, quoted in writing before we dispatch. This page is for Fort Worth homeowners and property managers who already own Sargent hardware and need to know whether to repair, rekey, or replace it, and what the work will actually cost. Call (817) 765-4998 for a written estimate.
How Sargent Products Fail - and How We Fix Them
- 10-Line lever sets with sagging return springs. The spring cassette behind the lever hub fatigues after roughly 8-12 years of daily use in Fort Worth’s humidity cycles, causing the lever to droop or fail to return to horizontal. We replace the cassette with an OEM Sargent spring pack rather than lubricating past the problem, which only delays the failure.
- B-series deadbolts with mushroomed driver pins. The original brass driver pins in pre-2015 B560 and B660 units deform under repeated keying changes, especially when previous locksmiths used soft aftermarket bottom pins. We pull the cylinder, measure pin wear with a caliper, and repin with nickel-silver pins that hold tolerance through successive rekeys.
- KEO / KP keyless entry units with corroded battery terminals. The battery sled in early KEO models sits too close to the door surface; condensation from Fort Worth’s spring storm fronts wicks into the compartment and green-corrodes the contacts. We clean the terminals, apply dielectric grease, and if the board is damaged, replace with a current-production KEO2 unit that relocated the seal point.
- 28-10G exit devices with dogging mechanism wear. The hex-key dogging screw strips its threads after repeated classroom or church use in Fort Worth ISD and Tarrant County facilities. We helicoil the housing when thread damage is minor; when it’s severe, we replace the dogging assembly rather than the entire device, which cuts the parts cost by roughly 60 percent.
- LC key-in-lever cylinders with split spacers. The nylon spacer between the cylinder plug and tailpiece crystallizes in attic-adjacent utility rooms during Fort Worth’s 100-degree summers, cracking when torque is applied. We find this most often in Ridglea and Wedgwood homes with converted garages. The fix is a steel-replacement spacer, not a full cylinder swap, unless the plug itself has scored.
Our Sargent Lock Installation & Rekey Process
- 1
Call and scope. You describe the lock, the keying situation, and what changed. We quote a firm price on the phone. Haven Standard Clause 1: the price on the phone is the price on the invoice.
- 2
On-site diagnostics. The technician photographs the existing hardware, checks the door prep dimensions (Sargent B-series requires a 2-1/8″ bore with a 1″ crossbore; older Fort Worth homes in Mistletoe Heights often have 1-3/4″ bores that need reaming), and tests the latch throw.
- 3
Parts decision. We stock Sargent OEM cylinders, springs, and latch assemblies. For discontinued lines like the early 8-line, we source quality aftermarket equivalents with matching face profiles, or we recommend migration to current 10-line hardware if the mounting prep allows.
- 4
The work. Rekeying is done on-site with a Sargent pinning kit; installations include new strike plates, proper screw length for Fort Worth’s common 1-3/4″ solid-core doors, and hand-check of every function.
- 5
Documentation and test. We cycle every key, test the thumbturn or lever return, and leave you with the written invoice, the new keys, and a photo record of the completed work. The 365-Day Done Right Promise applies from this moment.

FAQs
No. Sargent’s limited warranty covers defects in materials and workmanship; rekeying by a qualified locksmith does not void it. We are an independent Sargent service provider, not an authorized dealer, and we perform rekeying to factory tolerances using Sargent pinning kits. If your lock fails due to a manufacturing defect after our work, the warranty claim proceeds normally. Call (817) 765-4998 if you need documentation of our work for a claim.
Yes, for most lines. We stock cylinders, springs, and latches for current 10-line and B-series hardware. For discontinued 8-line and 6-line units, we maintain a parts inventory from decommissioned commercial jobs around Fort Worth, and we have relationships with specialty distributors. When OEM parts are exhausted, we specify quality aftermarket equivalents in writing before installation.
Rekey when the hardware is sound and you need new keys. Replace when the chassis is worn, the bolt throw is inconsistent, or you need a function change (passage to storeroom, for example). During our diagnostic, we measure bolt throw, check lever return torque, and inspect the strike engagement. We tell you what we found, then quote both options. Call (817) 765-4998 for a free assessment.
Most residential rekeys are completed same day, often within two hours of your call. Commercial master-key projects requiring key charting and tiered pinning are scheduled, typically within 24-48 hours. We answer calls with a live person 24/7, and we quote a firm arrival window, not a four-hour block.
Yes. Haven Standard Clause 1 prohibits our technicians from changing the quoted price at the door. The price we say on the phone is the price on the invoice. If we encounter unexpected conditions (a seized cylinder requiring extraction, for example), we stop, explain, and quote the additional work before proceeding. You approve every dollar in writing. Call (817) 765-4998 for your written estimate.
