Why Lexington Homeowners Choose Strongbox Lock & Safe Co.
Lexington is a town where people stay. The same families have owned homes off Waltham Street and Marrett Road for thirty, forty, fifty years. They remember the last time a locksmith quoted $19 on the phone and billed $400 at the door. We don’t work that way. The price we quote is the price you pay - flat, upfront, before the truck rolls.
We’ve built our reputation here on being the company that shows up when we say we will, in uniform, with ID, and does the job once. Our technicians are background-checked and trained to work on everything from original 19th-century mortise locks in the historic district to Grade-1 Medeco and Mul-T-Lock cylinders in the newer custom builds off Route 2. Every job carries our 90-Day Done Right Promise - backed in writing, no paperwork, no arguing. If it’s not right, we come back.
Lexington homeowners in the Follen Heights and East Lexington areas know our trucks. They also know that when they call at 11 PM on a Saturday, a live person answers - no voicemail tree, no callback queue.

Why Lexington’s Climate & Housing Affect Your Locks
Lexington’s classic New England freeze-thaw cycle is harder on locks than most homeowners realize. Every November and March, we field calls from the 02420 and 02421 ZIP codes about deadbolts that suddenly bind or won’t fully throw. The cause is almost always seasonal: wood-frame door swelling and subtle frame shift as temperatures swing from 20°F to 50°F and back again. Colonial homes near the Battle Green are especially prone to this - their original frames have settled over two centuries, and a 1/8-inch seasonal movement is enough to misalign a strike plate that worked fine in October.
Exterior cylinders in unheated mudrooms and detached garages, common in Lexington’s older homes, collect moisture that freezes during nor’easters. We’ve replaced cylinders on Waltham Street that cracked from expansion after a January storm. The fix isn’t always a new lock - sometimes it’s a weather-rated cylinder, sometimes it’s adjusting the door alignment so the bolt throws clean year-round. A locksmith who treats Lexington like Anywhere, Massachusetts misses these patterns. We’ve been here since 2013, and we know what to look for before it becomes an emergency.

FAQs About Locksmith Services in Lexington
Most standard services in Lexington fall between $89 and $220, with lockouts around $95-$150 and rekeys at $25-$45 per cylinder. High-security installations or antique mortise rebuilding run higher, typically $200-$400. We quote your exact price on the phone before dispatching - call (877) 664-8139 for a free estimate.
Yes. We regularly rebuild and rekey original mortise locks in the Battle Green historic district, including Corbin and Reading cases, often fitting modern keyway inserts while preserving period-appropriate hardware. This is a specialty most suburban locksmiths don’t offer. If your home has working 19th-century locks, we can keep them working.
Lexington’s freeze-thaw cycle causes wood door frames to expand and contract, misaligning the strike plate. It’s a seasonal pattern we see across 02420 and 02421, especially in colonial homes with original frames. The fix is usually a door alignment adjustment, not a new lock - and we check for it during any service call.
Rekeying is almost always less expensive - typically $25-$45 per cylinder versus $140-$220 for new deadbolt installation. Rekeying changes who has keys without replacing the hardware. If your locks are sound, we recommend rekeying. If they’re worn, damaged, or you want to upgrade security, replacement makes sense. We’ll tell you straight which path fits your situation.
In most cases, yes. We offer same-day service throughout Lexington, with true emergencies getting priority dispatch. A live person answers every call, 24/7 - nights, weekends, and holidays included. Call (877) 664-8139 and we’ll give you an exact arrival time.
