Why Medfield Homeowners Choose Strongbox Lock & Safe Co.
Medfield is one of Massachusetts’ oldest towns, settled in 1651, and its housing stock tells the story. The genuine antique colonials, Cape Cods, and farmhouses that dominate neighborhoods along South Street, North Street, and the historic town center still run original or early-replacement mortise lock sets and skeleton-key hardware. A locksmith who can’t service a century-old mortise lock or rekey a period-appropriate rim cylinder will lose a significant share of the town’s most common service calls. We’ve built our reputation in Medfield by keeping those skills alive.
Our technicians are background-checked, uniformed, and present ID at every door. We quote a flat price on the phone - the price on the invoice matches exactly. Every job carries our 90-Day Done Right Promise in writing: if it’s not right, we come back, no paperwork, no arguing. Over 42 years in this trade, we’ve learned that the homeowners who intend to stay in their houses for decades - the profile of most Medfield residents we serve - want the job done once and never thought about again. That’s the standard we hold ourselves to.
We’re also the flat-price alternative to the $19-ad locksmith scam that has burned too many homeowners in Norfolk County. No bait-and-switch. No surprise charges. A square deal, every time.

Why Medfield’s Climate & Housing Affect Locksmith Work
Medfield sits in the Charles River watershed beneath a heavy tree canopy, and that combination creates persistently damp microclimates around door thresholds. Norfolk County’s hard freeze-thaw cycles do the rest. Exterior lock cylinders and deadbolt mechanisms seize or corrode faster here than in drier suburbs, which drives wintertime lockout calls and spring re-keying jobs after ice-storm season. We’ve replaced more frozen Schlage deadbolts in Medfield after January cold snaps than we care to count.
The housing stock amplifies these challenges. The overwhelming majority of Medfield’s homes are pre-1970, with substantial cohorts of pre-1900 colonials and antique Cape Cods. Solid wood door frames have settled and shifted over decades, causing deadbolt-to-strike misalignment that requires skilled adjustment rather than simple lock swaps. Meanwhile, the town’s affluence means homeowners increasingly layer smart locks and high-security hardware onto these older doors, creating compatibility challenges that demand both historical knowledge and modern training. We’ve seen $400 smart deadbolts fail in six months because they were installed on a door that hadn’t been properly assessed for frame condition. We assess first.

Yes - servicing century-old mortise locks, rim cylinders, and skeleton-key hardware is a core skill for our Medfield technicians, necessary because so many homes along South Street and North Street still use them.
