How Strongbox Lock & Safe Co. of New York City Was Born in New York City
It was a Tuesday in February, 2008, and Mrs. Castellano from Brooklyn Heights was crying on her stoop. She’d called one of those “$19 service call” locksmiths after her deadbolt jammed, and two hours later she was staring at a $647 bill for a lock she didn’t need, installed by a kid who wouldn’t show her any ID and barely looked at the door before declaring her Baldwin “unrepairable.” She called us that afternoon, still shaking, still holding the receipt like evidence at a trial.
We fixed her actual lock in twenty minutes with a $12 part. She made us coffee. She talked about her husband’s pension, how she’d budgeted everything down to the grocery list, how that one bill had wrecked three months. That night, we sat in our truck outside her building and made a decision. New York City didn’t need another locksmith. It needed a locksmith you could trust with your mother’s house keys. We called it Strongbox, after the iron box where my grandfather kept the deed to his place in Queens. The name meant something solid, something that stayed where you put it. We promised ourselves three things: flat prices quoted on the phone, licensed techs who show ID at the door, and no job finished until the customer understands exactly what we did. We’ve kept that promise for every job since.
Our Founder’s Personal Connection to the Locksmith Trade
I didn’t plan on locks. I planned on being useless, mostly, through my twenties, drifting through jobs that didn’t need my hands or my attention. Then my uncle Vinnie, who ran a hardware store on Atlantic Avenue, got sick one summer and asked me to cover the key-cutting counter. I figured two weeks, maybe I’d learn to cut a house key without mangling it.
The first morning, I watched him pin a Medeco cylinder by feel, his fingers moving like he was reading braille. The shop smelled like brass shavings and cutting oil, that particular metallic warmth that gets into your clothes. He let me try on a scrap cylinder and I botched it completely, springs pinging across the floor like popcorn. He didn’t yell. He just swept them up and handed me another. “Locks are honest,” he said. “They work or they don’t. People are complicated. Locks, you can learn.”
I spent ten years learning. Not just the mechanics, though I came to love that too, the way a properly pinned cylinder turns like it’s greased with butter, the satisfying clunk of a deadbolt throwing home. I learned what it means to stand in someone’s doorway at midnight while they’re locked out, scared, maybe a little ashamed. I learned that a locksmith sees people at their most vulnerable, and the job isn’t just technical, it’s human. You’re holding the literal key to someone’s safety, their sleep-at-night peace of mind.
If I weren’t doing this, I’d probably still be trying to find something that fits. Nothing else has. What gets me out of bed is the knowledge that somewhere in New York City today, someone is standing outside their door, cold or tired or late for work, and we can make that problem disappear. Not with a scam, not with a hard sell. Just with competence and a square deal. That’s rare enough to be worth building a life around.
Meet Our Team - The Person Behind Every Job
Marcus Deluca, Owner & Founder
I’m the person who answers when you call (877) 691-7931, and I’m the person who shows up at your door. State-licensed, insured and bonded, trained through a formal apprenticeship under my uncle and later certified through the Associated Locksmiths of America. I’ve worked on every kind of lock this city throws at you, from pre-war mortise sets in Gramercy Park walk-ups to Mul-T-Lock systems in new construction in Long Island City.
What makes me different from a franchise tech? I’m not trying to hit a quota and move to the next call. I live here. My kid goes to school three blocks from some of my customers. On Sundays you’ll find me at the Greenmarket in Union Square, and I once spent an entire Saturday helping a customer in Park Slope figure out her vintage Yale cabinet lock because she was curious, not because it was on the invoice. I believe a job’s not done until you’d be comfortable telling your neighbor to hire us. That’s the standard.
Our Promise to New York City Homeowners
We built our K.E.Y.S. code after too many conversations with people who’d been burned. Here’s what it means in practice.
Krafted right: We use proper materials, trained journeymen, no shortcuts. A customer in Hell’s Kitchen once asked why we wouldn’t just drill her lock, it’d be faster. We picked it, repaired it, and she’s still using it twelve years later. That’s the difference.
Every time: The 400th job gets the care of the first. We keep records on every lock we’ve touched. When Mrs. Castellano called us back in 2019, we remembered her door, her hardware, her preference for Baldwin brass.
Your home first: We work in your house the way we’d work in our mother’s. Boot covers, drop cloths, vacuuming after. A locksmith in your bedroom should be the most careful person you’ve ever invited inside.
Standing behind it: The Keystone Standard, applied to locks. Ninety days, in writing, no arguing. If it’s not right, we come back. No paperwork battle, no “read the fine print.” We fix it because we said we would.
Our Credentials
Licensing: State-licensed locksmith, fully compliant with New York State requirements. No license number games, no “pending” status. We’re the real thing, documented and current.
Insurance & Bonding: Insured and bonded for your protection and ours. When someone works on the locks securing your family, they should carry proper coverage. We do.
Experience: Years of hands-on work across New York City’s five boroughs and beyond. We’ve serviced locks in brownstones, high-rises, storefronts, and safes in basements from Chinatown to Greenpoint. That breadth matters when your particular problem doesn’t match the textbook.
Reputation: Strong local reputation built one job at a time. We don’t buy reviews, we don’t pressure customers, and we don’t disappear when something goes wrong. Ask around in Brooklyn Heights or Gramercy Park. Someone you know has our number.
Why this matters to you: a locksmith holds the keys to your security. State licensing means we’ve passed background checks and competency standards. Insurance means you’re protected if something goes wrong. Years of local experience means we’ve seen your exact lock, your building’s quirks, your neighborhood’s particular challenges. And a reputation you can verify means we’re not vanishing into the night with your money and your sense of safety.
Rooted in New York City
We’re not a dispatch center in another state. We’re here. We’ve rekeyed apartments for families moving into their first place in Williamsburg, installed Medeco systems for small businesses in the Financial District, and answered 2 AM lockouts in Long Island City when the super’s number goes to voicemail. We’ve sponsored the block association raffle in Park Slope and fixed the community garden shed lock in the East Village for nothing but a cup of coffee. New York City isn’t where we operate. It’s where we live, where we raised our family, where we’ll still be when you need us again in ten years. That’s the difference between a company and a neighbor.
