Lock Change in Gaithersburg, MD

When to change Gaithersburg locks vs. just rekey them

The honest answer: most Gaithersburg homes benefit from a hybrid. Rekey the locks that are still mechanically sound, replace the ones that are not. Builder-grade hardware on new construction in Crown or Saybrooke usually deserves an upgrade to Grade 2 deadbolts within the first year. Older hardware in Olde Towne and Quince Orchard sometimes needs full replacement when the cylinders are worn or the latches no longer align cleanly with the strike plate. We carry rekey kits and replacement deadbolts on the same truck so we can decide door by door, not in advance.

What a Gaithersburg lock change actually looks like, start to finish

We arrive within your scheduled window. We walk every exterior entry with you to confirm the scope and surface anything that needs attention beyond what was quoted on the phone. We present three hardware tiers (typically a Grade 2 standard, a Grade 1 high-security, and a smart-lock option). You pick. We remove the old hardware without damaging the door or finish, install the new locks, install reinforced 3-inch strike screws, test every key in every direction (interior knob to deadbolt, deadbolt to strike, latch to frame), and vacuum the work area before we leave. You receive a written invoice listing every part installed and applicable warranty terms.

Smart lock installs and high-security upgrades for Gaithersburg homes

Two upgrade paths are common in Gaithersburg. Smart-lock installs (Schlage Encode, Yale Assure with Wi-Fi, August retrofit, Kwikset Halo, Level Lock+) for families that want keyless entry and remote access for kids, dog walkers, and cleaners. And high-security restricted-keyway upgrades (Medeco, Mul-T-Lock, Schlage Primus) for homeowners who want keys that cannot be duplicated at retail kiosks. We are an authorized installer for all of the above and can advise on the right fit for your doors, your Wi-Fi setup, and your HOA hardware standards.

Hardware brands we stock on the truck for Gaithersburg lock changes

Truck loadout matters because the wrong stock on board turns a one-visit lock change into a two-visit drag with a parts delay in the middle. For Gaithersburg residential calls we carry Schlage B-series and BE-series deadbolts in satin nickel, oil-rubbed bronze, polished brass, and matte black, Kwikset SmartKey deadbolts in the same finishes, Yale Assure 2 smart locks in two finishes, Schlage Encode Plus smart locks, and Grade 1 commercial cylinders for the priority front and back entries. For high-security upgrades we stock Medeco Maxum and Mul-T-Lock MT5+ cylinders that fit standard Schlage and Kwikset deadbolt bodies, so you keep your existing exterior look while gaining full key-control. The result is most Gaithersburg lock change jobs finish in a single visit, no waiting for parts.
