Deadbolt Installation in Lake Mary, FL | Done Right the First Time
A deadbolt is only as strong as its installation. We install and replace deadbolts on every door type — wood, fiberglass, steel — with proper alignment, reinforced strike plates, and hardware that actually fits your door.
Whether you’re adding a deadbolt where there wasn’t one, upgrading tired builder-grade hardware, or replacing a deadbolt that no longer throws cleanly, we do it in one visit with an upfront price and a lock you test yourself.
How Long Does Deadbolt Installation Take?
A straightforward replacement — old deadbolt out, new one in — usually takes well under an hour. Installing a deadbolt on a door that never had one takes longer, since we bore the holes, mortise the strike, and fit everything precisely. Either way, it’s a single visit.
What matters more than speed is correctness: a deadbolt that isn’t aligned throws short, wears fast, and can fail when you need it. We fit, align, and test every installation before we leave.
Deadbolt Work We Do Every Day
Single-Cylinder Deadbolts
Key outside, thumb-turn inside — the standard for most homes. We install quality single-cylinder deadbolts (Schlage, Kwikset, and better) with correct backset, clean bore work, and smooth operation from day one.
Double-Cylinder Deadbolts
Keyed on both sides — the answer for doors with glass panels, where a burglar could otherwise break glass and turn a thumb-turn. We’ll explain the fire-egress tradeoff honestly so you choose with eyes open.
Strike Plate Reinforcement
Most kick-ins defeat the strike plate, not the lock. We install reinforced strikes with long screws anchored into the wall stud — the single biggest strength upgrade for the money, and we recommend it on every install.
Worn Deadbolt Replacement
A deadbolt that needs force to throw, or one that sticks halfway, is telling you its internals are done. We replace it with properly fitted hardware — and check the door alignment, which is often half the problem.
Smart Deadbolts
Want keyless convenience without giving up deadbolt strength? Electronic deadbolts deliver both. We install and program them — see our smart lock installation page for the full rundown.
Keyed-Alike Deadbolts
One key for the front, back, and garage-entry deadbolts. When we install multiples, we key them alike at no extra fuss — and rekey your existing locks to match.
Deadbolt Installation for Lake Mary Homes
Most Lake Mary homes have deadbolts — but many are the builder’s minimum: light-duty hardware, short strike screws, and alignment that’s drifted over the years. Our residential deadbolt work starts with an honest assessment of what you have. Our residential locksmith services page covers the full range of home security work.
Sometimes the right answer is a full replacement with a quality deadbolt and reinforced strike. Sometimes it’s an adjustment and a rekey of the hardware you already own. We’ll tell you which — and if your lock is fine, we’ll say that too. If you’re locked out right now, our emergency service comes first; the upgrade can wait a day.
Deadbolts for Businesses
Offices, retail, and rental properties need deadbolts that survive daily abuse. Our commercial locksmith services include commercial-grade deadbolts, keyed-alike systems across multiple doors, and restricted keyways so staff can’t duplicate keys on their own.
For higher-threat situations — cash handling, inventory rooms, after-hours access — we step up to high-security deadbolts with pick, bump, and drill resistance. We’ll match the hardware to the actual risk, not oversell it.
We Come to You — Anywhere in Lake Mary
Deadbolt installation is fully mobile work. We bring the boring jigs, hole saws, chisels, and a range of deadbolts in common finishes — so whether you need one deadbolt or every door in the house, it’s done on site in a single visit.
From Heathrow’s gated streets to Sanford’s older homes, we fit deadbolts to wood, fiberglass, and steel doors alike. Tell us your door type when you call and we’ll bring the right approach.
Deadbolt Options & Honest Advice
For most homes, a quality single-cylinder deadbolt from Schlage or Kwikset — properly installed with a reinforced strike — is the sweet spot of security and value. Step up to high-security cylinders (Medeco, Mul-T-Lock) when you want pick/bump resistance and restricted keys. The hardware matters, but the installation matters more: a premium deadbolt in a misaligned door with a flimsy strike is still a weak door.
We also check the door itself. A deadbolt can’t fix a hollow, flexing door or a frame that’s pulling away — we’ll point that out before selling you a lock, because the honest fix might be carpentry first.
Single or double cylinder — which should I choose?
Single-cylinder (thumb-turn inside) for most doors — it’s safer in a fire because you can always get out without a key. Double-cylinder (keyed both sides) only where there’s glass within arm’s reach of the lock, since it stops someone breaking glass and turning the thumb-turn. The tradeoff is real: with double-cylinder, you need the key to exit, so keep one accessible. We’ll walk you through it for your specific doors.

Frequently Asked Questions About Deadbolt Installation in Lake Mary, FL
Single or double cylinder — which do I need?
Single-cylinder (thumb-turn inside) suits most doors and is safer in emergencies since you can always exit without a key. Choose double-cylinder (keyed both sides) only when glass sits within arm’s reach of the lock. We’ll assess your doors and recommend honestly — most homes need single-cylinder throughout.
Can you install a deadbolt on a fiberglass or steel door?
Yes — wood, fiberglass, and steel doors all take deadbolts, each with its own technique. Steel doors need the right bits and patience; fiberglass needs care to avoid cracking. Tell us your door type when you call so we bring the correct tooling.
My deadbolt sticks and needs force. Can it be fixed?
Often yes. Sticking usually means misalignment — the door shifted and the bolt drags on the strike. We realign the strike, and if the cylinder itself is worn, we replace it. We’ll diagnose honestly rather than defaulting to a full replacement.
Will the new deadbolt match my existing handle?
Usually. We stock the common finishes (satin nickel, bronze, brass, matte black) and match brands where it matters. Bring a photo of your existing hardware or just show us on site — matching is part of the job.
Is a more expensive deadbolt actually safer?
Up to a point. A quality mid-range deadbolt, properly installed with a reinforced strike, beats a premium lock installed sloppily every time. Beyond that, high-security cylinders add real pick, bump, and drill resistance. We’ll match the hardware to your actual needs.
Can you key my new deadbolt to match my other doors?
Yes — keying alike is standard when we install. If your existing locks are a different brand with a compatible keyway, we rekey them to match too, so one key runs the whole house.
