Call (877) 664-8139

We’ve been serving Exeter homeowners for over 42 years, from the colonial-era center around Water Street to the rural acreage off Route 27 and the faculty neighborhoods near Phillips Exeter Academy. Exeter’s housing stock demands a locksmith who understands 200-year-old door frames that have settled and shifted, institutional master-key systems, and the hard freeze-thaw cycles that seize exterior cylinders every winter. When you call (877) 664-8139, a live person answers - no voicemail, no callback queue - and we quote a flat price before any truck rolls.

Why Strongbox Lock & Safe Co. Is Exeter’s Preferred Lock Installation & Rekey Company

Exeter residents know the difference between a locksmith who shows up prepared and one who makes a second trip because the truck wasn’t stocked for 19th-century mortise hardware. Our Lock Installation & Rekey team carries Schlage, Medeco, and Yale cylinders in multiple finishes, plus the shims, strike plates, and long-throw deadbolts needed for thick historic doors. We don’t guess at what we’ll find.

Our reputation here is built on showing ID at the door, wearing a Strongbox uniform, and leaving a written 90-Day Done Right Promise with every invoice. The price we quote on the phone is the price you pay. We’ve rekeyed faculty homes near the Academy, installed keypad locks on ranch houses in the post-war neighborhoods off Portsmouth Avenue, and extracted broken keys from Federal-era entry sets on Front Street. Exeter customers call us back because the job stays done.

Response time matters in a town where a detached workshop lockout or a student dormitory issue can’t wait until morning. We answer calls 24/7, including nights, weekends, and holidays. A live person, every time.

Our Lock Installation & Rekey Services in Exeter

Smart Lock Installation

Smart lock installation in Exeter runs $195-$425 for most residential doors, with premium biometric and keypad models at the higher end. Historic Exeter homes present a specific challenge: many original entry doors measure 1¾ to 2¼ inches thick, well beyond standard smart lock specs. We stock extended spindle kits and reinforced strike plates so your Yale or Kwikset smart lock mounts solidly without compromising the door’s integrity. For Academy-area rentals and faculty housing, we also configure temporary access codes that reset between tenants - a small detail that saves a full rekeying later.

Keyless Entry

Keyless entry systems for Exeter properties range from simple keypad deadbolts at $165-$285 to full electronic lever sets with audit-trail logging at $340-$485. Rural-acreage owners particularly value keyless entry for detached workshops and barns where carrying a full key ring across a long driveway isn’t practical. We install weather-rated keypads that withstand Exeter’s freeze-thaw cycling, and we program them on-site so you’re not deciphering factory instructions in a drafty doorway. Our field vignette: We rekeyed a colonial-era farmhouse on Linden Street with a seized Schlage deadbolt caused by freeze-thaw moisture; the owner also requested a heavy-duty garage-door opener for his detached workshop, which we installed in one trip to avoid a second drive from our Portsmouth base.

Keypad Lock

Keypad lock installation in Exeter typically costs $155-$295 for residential-grade hardware, with commercial-duty models for Academy buildings and multi-family properties running higher. Exeter’s January-March thaw periods destroy cheap exterior electronics - we specify units with IP65 weather sealing and operating ranges down to -20°F, because a keypad that fails in February is worse than no keypad at all. For Phillips Exeter Academy dormitories and administrative buildings, we source institutional-grade keypad locks compatible with existing Corbin Russwin and Schlage master-key hierarchies.

Biometric Lock

Biometric lock installation in Exeter starts around $285 for fingerprint-entry deadbolts and extends to $485+ for multi-factor commercial units. These make sense for Exeter’s home offices, gun rooms, and workshop spaces where key control is difficult among family members or seasonal workers. We calibrate sensors for cold-weather performance and program backup access methods so a low battery or dirty finger doesn’t lock you out of your own property.

Trusted Brands We Service in Exeter

We install and service Kwikset, Medeco, Yale, and Baldwin hardware from stocked inventory, which means no waiting on parts for most Exeter jobs. Medeco’s high-security cylinders are a natural fit for Academy-area properties and rural workshops with valuable equipment. Yale’s residential smart locks integrate cleanly with most home automation systems popular among Exeter’s long-term homeowners. Baldwin’s solid brass and bronze finishes match the architectural character of historic Water Street and Front Street properties without looking like an afterthought. When we quote your job, we specify the exact model and finish - not “a lock like this” - because the right hardware matters on a door that may outlast all of us.

Common Lock Installation & Rekey Problems We See in Exeter Homes

• Moisture-seized deadbolts on historic frames during January-March freeze-thaw cycles. Exeter’s inland Seacoast location delivers hard freeze-thaw cycling through winter - typically dozens of cycles per season - which forces moisture into exterior deadbolts and padlocks on older, gap-heavy door frames common in 18th- and 19th-century construction. We replace corroded cylinders or apply penetrating lubricant formulated for lock mechanisms, not generic WD-40 that gums up pins.
• Misalignment on shifted 200-year-old door frames that jams standard strikes. A door that latched fine in October won’t catch in March after frost heave. We custom-shim or relocate strike plates rather than forcing modern hardware into a frame that has spent two centuries settling.
• Improper keying of institutional cylinders for Phillips Exeter Academy dormitories. Academy dorm lockouts are a category of their own: Phillips Exeter’s residential houses each have their own keying hierarchy, and a student locked out at 11 p.m. on a Sunday cannot wait until Monday. Locksmiths who understand institutional dormitory lock hardware and can navigate campus security protocols reliably win that recurring late-night volume.
• Detached workshop and oversized garage door lockouts on rural-acreage properties. Exeter’s rural-acreage properties often have detached workshops and oversized garage doors requiring heavy-duty openers and springs, plus long service drives that demand one-trip efficiency - a service profile absent in denser Seacoast towns. We stock heavy-duty slide bolts, hasps, and electronic opener systems for these outbuildings.
