Schlage Lock Rekeying: The Ashburn Owner’s Guide
Schlage lock rekeying in Ashburn typically runs $29-$49 per cylinder for standard residential deadbolts and knobs, with most jobs completed same-day and priced in writing before we dispatch. We stock Schlage key-in-knob, deadbolt, and SmartKey-compatible cylinders on every van, including the common SC1 and SC4 keyways found in Ashburn homes built between 2015 and 2022. Most owners discover a rekey is needed after closing on a resale, after a tenant turnover, or when a key starts catching at 45 degrees in the cylinder - a sign the pin stacks are wearing unevenly from Virginia’s humidity swings.
Which Schlage Models This Applies To
We rekey the full Schlage residential line: the B-series deadbolts (B60, B62, B63), F-series knobs and levers (F51, F54, F58, F93), and the Connect and Sense smart deadbolts when the cylinder module is serviceable. The keyway stamped on your key bow tells us what we’re working with: SC1 for the classic 5-pin system, SC4 for the 6-pin upgrade common in newer Broadlands and Brambleton builds. The cylinder length matters too - a standard 1-1/8″ face-to-tailpiece spec fits most Ashburn entry doors, but the thicker solid-core doors in One Loudoun townhomes often need the 1-3/8″ extended cylinder we carry as standard stock.
OEM Schlage cylinders ship with factory-matched pins and springs. We also stock GMS and Ilco aftermarket equivalents that meet the same ANSI Grade 2 spec at a lower unit cost; the difference is finish matching and, on some lots, slightly tighter pin tolerance. For a rental turnover or a home sale rekey, the aftermarket cylinder performs identically. For a high-traffic commercial door, we specify OEM. We are an independent service provider - not affiliated with Schlage - and we stock both because the right part depends on how the door gets used, not the logo on the box.
Signs Your Schlage Lock Rekeying Is Failing

- Key rotates but the bolt doesn’t throw. The tailpiece clip has sheared or the cam slot in the cylinder housing has elongated. This is common on Schlage F-series knobs in Ashburn’s older townhome stock, where the original installer used a drive-in latch instead of the faceplate the door prep actually required.
- Key sticks at the 10 o’clock or 2 o’clock position. One or more pin stacks have developed a burr, or the cylinder has collected enough airborne grit from Virginia clay-road dust to bind the plug. We see this most in homes within a quarter-mile of active construction, which describes half of Ashburn at any given time.
- Different keys now operate the same lock. Worn pin chambers have lost their precision tolerances. On a 5-pin SC1 cylinder, this typically starts at the 3 and 4 positions - the most actuated pins - after roughly 8-12 years of daily use.
- The key won’t insert fully on cold mornings. The plug has compressed slightly in the housing bore, a condition accelerated by the 30-degree temperature swings common to Loudoun County winters. A drop of graphite masks it temporarily; the cylinder needs rekeying or replacement.
- Loose cylinder face rotates with the key. The retaining pin or C-clip has backed out. On Schlage deadbolts, this is usually a 5-minute fix with the right clip tool. On knobs, it often means the housing threads are stripped and the full cylinder needs replacement.
Replacement Cost & What’s Included
Standard Schlage rekeying in Ashburn runs $29-$49 per cylinder, including pin reconfiguration, key cutting for two new keys, and cylinder reinstallation. If the cylinder itself is damaged and needs replacement, add $35-$65 for the part - OEM Schlage at the upper end, quality aftermarket at the lower. Commercial-grade Schlage Primus or Everest cylinders, or any high-security sidebar system, are priced separately and surveyed on site.
Haven Standard Clause 1 applies: the price we quote on the phone is the price on the invoice. No call-out surcharge, no “trip fee” added at the door. The technician is contractually prohibited from changing the quoted figure. Every rekey includes a documented photo record of the cylinder condition before and after, left with you at completion, and the 365-Day Done Right Promise covers the work if the keying doesn’t operate smoothly.
DIY or Call Us?

A homeowner can safely verify the keyway stamp and count the pins by looking at the key bow - SC1 shows five peaks, SC4 shows six. You can also confirm whether the cylinder face is loose by gentle hand pressure. What you should not attempt: removing a cylinder without a follower tool to retain the top pins and springs. Schlage cylinders use light-gauge springs under modest compression, but a slipped follower sends pins into the housing bore or across the entryway floor. Rekeying without a pinning kit means guessing at depths, and a single mis-cut key will jam the plug solid.
We carry Schlage pinning kits, depth keys, and factory code books on every van. A standard residential rekey takes 20-30 minutes on site. If you’re weighing the cost of a $40 pinning kit you’ll use once against a quoted $29-$49 service call, the math usually points to calling. The name on the invoice is the same name on the van.
FAQs
A properly rekeyed Schlage cylinder in residential use typically lasts 10-15 years in Ashburn’s climate, though homes near active construction may see earlier wear from particulate infiltration. Call (571) 410-8874 for an exact quote - estimates are free.
Yes, if the failure is a loose retaining clip, a bent tailpiece, or a lubrication issue. If the pin chambers are worn or the plug is scored, rekeying with a new cylinder is the cost-effective repair. We diagnose on site and quote both paths before starting work.
Most single-cylinder residential rekeys are completed in 20-30 minutes; whole-house rekeying with 4-6 cylinders runs 60-90 minutes. We stock Schlage, Kwikset, and Medeco parts to avoid a return trip.
Yes - SC1 and SC4 keyway cylinders in standard and extended lengths, plus SmartKey conversion kits and commercial-grade Primus housings. We also stock Kwikset and Medeco equivalents for mixed-brand homes. If your model is unusual, we’ll verify by photo before dispatching.
