Sargent Lock Rekeying: The Washington Owner’s Guide

Sargent lock rekeying in Washington typically runs $45-$85 per cylinder when done on-site, and we carry the full pin kit for Sargent 6300, 6500, and 4800 series locks on every truck. Most residential rekeys in Washington’s Capitol Hill, North End, and Tumwater areas are finished inside of thirty minutes. You’ll know it’s time when your key starts catching at 10 o’clock, a new tenant moves in, or you’ve simply lost track of who has copies after twenty years in the same house.

Which Sargent Models This Applies To

Sargent’s residential and light commercial lines have been common in Washington since the 1980s, and the cylinder architecture hasn’t changed much, which is good news for rekeying. We regularly work on the 6300 series knob sets, the 6500 series levers, and the 4800 series deadbolts found in many of the split-levels and rambler homes built around South Sound between 1975 and 2005.

To identify your series, look for the Sargent stamp on the key bow or the face of the cylinder. The keyway profile matters: LA keyways are the standard residential profile, while LB and LD keyways appear on commercial-grade hardware and require a different pin kit entirely. We stock both, but the quote changes if you’ve got an LB cylinder hiding behind a residential lever.

OEM Sargent pins are brass with nickel silver drivers, and we keep them on hand. Aftermarket equivalents from LAB and A1 exist and work fine for standard rekeys, though we default to OEM for any master-keyed system or high-turnover rental property where long-term pin stability matters. Washington’s damp winters can accelerate corrosion in cheaper alloys, so we don’t cut corners on pin material.

Signs Your Sargent Lock Rekeying Is Failing

• Key sticks or hangs at the 10 o’clock position. This usually means worn pins have developed flat spots where the key lifts them, or the driver springs have lost tension after years of use. In Washington’s older homes, we see this most often on back doors that get used ten times a day.
• You need to jiggle the key to find the sweet spot. That’s pin wear combined with a key that has been copied too many times. The original Sargent key has tight tolerances; a worn copy forces the pins to ride at odd angles.
• The key turns but the bolt doesn’t retract. This isn’t always a rekey issue, but if you’ve just had keys made and the problem started, the new key may be lifting pins to the wrong shear line. We check cylinder alignment before we touch the pin stack.
• You’re not sure who has keys anymore. After a divorce, a death, a tenant turnover, or twenty years of handing out copies to dog walkers and grandkids, rekeying resets access without replacing hardware. This is the most common call we get in Washington’s long-established neighborhoods.
• The lock was rekeyed before, and now it feels loose. A previous locksmith may have used undersized pins or skipped a chamber. We see this on quick-turn rental rekeys where speed beat precision.

Replacement Cost & What’s Included

For standard Sargent rekeying in Washington, expect $45-$65 for a single residential cylinder and $75-$85 for a commercial-grade cylinder with master-keying capability. Two-cylinder jobs, common on front doors with a deadbolt and knob set, typically run $80-$120 total.

That price includes disassembly, pin replacement with OEM or matched aftermarket pins, key cutting for two new keys, and testing for smooth operation across the full rotation. If we find a damaged spring, worn cam, or cracked plug, we’ll show you before we fix it. No surprises.

Every rekey carries our 90-Day Done Right Promise, backed in writing. If the key hangs, sticks, or doesn’t feel right, we come back. No paperwork to file, no argument.

DIY or Call Us?

Rekeying a Sargent cylinder isn’t dangerous like a garage door spring, but it’s easy to turn a $60 job into a $200 one. The follower tool that pushes the plug out without dropping pins costs more than our service call, and if you lose a driver spring into the carpet, you’re buying a new cylinder.

What you can safely check: confirm your keyway type from the stamp on the key bow, and count how many keyed cylinders you have. What we handle: disassembly in a controlled environment, pinning to factory spec, and verifying the shear line under magnification.

We quote the price before the truck moves. That’s just how this should work. Call (888) 545-8474 and we’ll give you a flat number based on your series and how many cylinders need work.
