Sargent Lock Rekeying: The Florida Owner’s Guide
We stock and install Sargent-compatible lock rekeying kits for residential and commercial hardware across Florida, with same-day service available in most metro areas. Most Sargent rekeying jobs run between $89 and $175 installed, depending on cylinder type and whether the lockset needs removal. Homeowners usually discover a rekeying need after a move, a lost key, or when a tenant or employee change leaves them unsure who has access.
Florida’s humidity and salt air accelerate internal wear on pin tumblers, so we see more sticking and jamming here than our colleagues up north. If your Sargent key is getting harder to turn or you’ve got a cylinder that won’t accept a new key cut, the rekeying pins and springs inside are likely worn or mismatched. Randall Odom and our technicians carry Sargent-compatible pinning kits, top pins, bottom pins, and master wafers on every truck.
Which Sargent Models This Applies To
Sargent has manufactured hardware since the 1860s, and their product lines span everything from Grade 2 residential deadbolts to Grade 1 commercial mortise cylinders. The most common models we rekey in Florida homes and small businesses are the 6300 series cylindrical locks, the 6500 line of heavy-duty commercial levers, and the 4800/4900 series deadbolts. Look for the Sargent name stamped on the faceplate or escutcheon; inside the cylinder housing, you’ll often find a date code and series number that tells us exactly which pinning kit to pull.
The 6300 series uses a standard .115 diameter bottom pin, while the 6500 commercial levers often run .108 diameter pins with longer master wafers for keyed-alike systems. Here’s where DIY ordering goes wrong: Sargent’s 10-line and 11-line keyways look nearly identical but take different blank profiles, and forcing the wrong key can shear a pin or jam the plug. We stock both OEM Sargent pinning kits and quality aftermarket equivalents from LAB and HPC; for master key systems, we recommend OEM to maintain factory tolerances. For a single-family rekey after a move, aftermarket pins save money without sacrificing security.
Signs Your Sargent Lock Rekeying Is Failing
- Key sticks or requires jiggling to turn. Worn bottom pins have lost their sharp factory edges, or accumulated Florida grit and salt residue has gummed the pin chambers. Rekeying with fresh pins restores smooth operation without replacing the entire cylinder.
- Key turns but bolt doesn’t retract. The tailpiece or cam has slipped alignment, often because someone forced the key against a partially engaged pin stack. This isn’t strictly a rekeying fix, but we diagnose it during the same visit and handle both.
- Newly cut key works intermittently. A previous rekeying job used mismatched pin lengths or a worn key duplicator produced an off-spec blank. We measure pin depths with a decoder and cut to factory spacing.
- Master key stops working on one door. A master wafer has worn down or a bottom pin has compressed from repeated cycling. Florida’s heat expansion cycles stress these small parts more than in temperate climates.
- Key extraction requires force. Binding pins, often from corrosion or debris in the plug, create friction against the key blade. Rekeying includes full disassembly and cleaning of the pin chambers.
Replacement Cost & What’s Included
| Service | Price Range | What’s Included |
|---|---|---|
| Standard Sargent rekey (1-2 cylinders) | $89 - $135 | Disassembly, pin replacement, 2 new keys, reassembly, function test |
| Commercial Sargent rekey (master key system) | $125 - $175 | OEM pins, master wafer setup, key schedule documentation, 3 keys |
| Additional cylinders same visit | $35 - $55 each | Same pinning, keyed alike or differently per your instruction |
| Broken key extraction + rekey | $110 - $160 | Key removal, pin inspection, rekey if damaged, new keys |
What drives the range: cylinder accessibility (a mortise cylinder in a glass storefront takes longer than a residential deadbolt), master key complexity, and whether we need to order a rare Sargent keyway. We quote it flat before we roll, and we stand behind it when we’re done. Every rekeying job carries our 90-Day Done Right Promise - backed in writing, no arguing, no extra paperwork. Seniors and veterans receive a standing 5% discount.
DIY or Call Us?
A homeowner can safely check two things before calling: confirm the keyway isn’t blocked with visible debris, and verify you’re using the correct key (Sargent keys are stamped with the keyway profile on the head). Beyond that, rekeying requires removing the cylinder, extracting the plug without dropping pins into the housing, and installing new pins at precise depths measured in thousandths of an inch.
Here’s where DIY goes wrong: the follower tool slips, springs launch across the room, and you’re left with a disassembled cylinder and no way to secure your door tonight. Worse, a mis-pinned cylinder can appear to work until it fails completely - often at 10 PM with your key stuck inside. We carry pinning kits, decoders, and replacement springs on every truck, and we guarantee the key works smoothly before we leave.

FAQs
How long does a Sargent rekey take?
A standard residential rekey takes 20 to 40 minutes per cylinder once we’re on site. Commercial master key systems or hard-to-access mortise cylinders run 45 minutes to an hour. We carry parts for same-day completion in nearly every case. Call (844) 956-4715 to schedule - estimates are free.
Can a worn Sargent lock be repaired instead of rekeyed?
Sometimes. If the plug, springs, and cam are intact, rekeying with fresh pins restores function at a fraction of replacement cost. If the cylinder body is cracked, the keyway is wallowed out, or the latch mechanism is failing, we recommend full replacement. Randall Odom or our technician will show you the condition and quote both options before any work begins.
Do you stock Sargent rekeying parts on your trucks?
Yes. We carry LAB and HPC pinning kits in standard Sargent keyways, plus OEM Sargent master wafers for commercial systems. Our trucks are restocked weekly from our Florida warehouse. For obsolete Sargent keyways or restricted profiles, we can often source parts within 24 hours.
How long do rekeyed Sargent pins last in Florida?
With normal residential use, expect 10 to 15 years from quality pins in Florida’s climate. Commercial doors with high daily cycle counts may see 5 to 7 years. Salt air near the coast accelerates corrosion; we apply a dry lubricant during rekeying that extends pin life. Our 90-Day Done Right Promise covers the workmanship regardless of environmental conditions.
