Why Callers Choose SND Heating and Air Conditioning for Locksmith in Armonk, NY

Professional Tools & Hardware
Expect a full mobile setup: rekeying kits with every pin size, plug followers, a key duplicator, boring jigs, and commercial-grade locks ready to install.
Here's what years of routing locksmith calls have taught us: most lock problems aren't really lock problems. A deadbolt that's hard to turn usually means the door has sagged on its hinges, a lock that freezes in winter often needs graphite rather than oil, and a key that only works when you jiggle it is worn, not the cylinder. A good locksmith checks the whole door, not just the hardware, and fixes the cause instead of selling you a new lock you don't need. Ask the locksmith to cut a fresh key from code instead of copying a worn one, which keeps your new locks working smoothly for years.
Lock and Key Work Handled in Armonk
Whether it's one front door or an entire office building, here's the work network locksmiths take on.
Rekeying and Lock Changes
Rekeying is usually the smartest move after you buy a home, lose a key, or part ways with a roommate or employee. The locksmith removes the cylinder plug, swaps the pin tumblers to match a new key bitting, and your old keys stop working without replacing any hardware. Most homes can be keyed alike so you carry one key instead of five.
- New-home rekeys
- Keyed-alike setups
- Worn cylinder replacement
Deadbolt and Smart Lock Installation
A strong deadbolt starts with ANSI/BHMA Grade 1 or Grade 2 hardware, a full one-inch throw, and a reinforced strike plate anchored with three-inch screws into the stud. Smart lock installs, keypad programming, boring new doors, and realigning strikes on bolts that bind are routine work.
- Grade 1 and Grade 2 deadbolts
- Smart and keypad lock setup
- Strike plate reinforcement
Master Key Systems and Key Control
A master key system gives each person access to just the doors they need, while owners and managers carry a single master. Restricted or patented keyways keep unauthorized duplicates from being made down the street.
- Master and sub-master systems
- Restricted keyways
- Rekeys after turnover
Commercial Door Hardware
Commercial doors cycle hundreds of times a day, and worn hardware can become a fire code problem as well as a security problem. Independent commercial locksmiths repair and install mortise locks, panic bars and exit devices, storefront deadlatches, door closers, and ADA-compliant lever trim.
- Exit devices and panic bars
- Mortise locks and storefront latches
- Door closer repair
High-Security Lock Upgrades
Standard pin tumbler locks can be picked or bumped by anyone with a cheap tool set and an online tutorial. High-security cylinders add sidebars, hardened steel inserts, and anti-drill pins, and their key blanks are tightly controlled. They're a smart upgrade for home offices, detached garages, and shops with valuable inventory.
- Bump- and pick-resistant cylinders
- Drill-resistant inserts
- Controlled key duplication
Keys, Safes, and Cabinet Locks
Beyond doors, locksmiths duplicate standard and high-security keys, cut keys by code, open and service safes, change combinations, and replace mailbox, desk, and file cabinet locks.
- Key duplication and code cutting
- Safe openings and combination changes
- Mailbox and cabinet locks

Customer Reviews and Experiences
We closed on our house on a Thursday and had no idea how many copies of the old keys were out there. The locksmith rekeyed five locks to a single key in about forty minutes and let me watch the new pins go in. The price matched the quote exactly.
Our ServicesOur Services in Armonk, NY
Every tenant turnover meant another round of lock changes across my building. The locksmith set up a master system with a restricted keyway. Now each unit has its own key, I carry one master, and turnover means repinning a single cylinder.
The fire marshal flagged our back-door panic bar, and we were on the clock. The commercial locksmith replaced the worn latch, adjusted the closer so the door actually latched, and had us passing reinspection before the deadline.
Our front deadbolt got harder to lock every week, and I assumed it was shot. The locksmith showed me the bolt was hitting the edge of the strike because the door had sagged. He reset the hinges with longer screws, moved the strike, and it locks with one finger now. No new lock needed.
I run a small dental office and had no idea how many former employees still had keys. The locksmith rekeyed the suite, set up restricted keys that can't be copied without my authorization, and gave me a simple log to track who has what.
What Callers Ask Us Most
How much does it cost to rekey a house?
Pricing is set by the independent locksmith and usually includes a service call plus a per-cylinder charge. Rekeying typically costs far less than replacing locks because the hardware stays in place. You'll get the total before work starts, so feel free to ask about the per-lock rate when you call.
Should I rekey or replace my locks?
If the locks work smoothly and you simply want control of who has keys, rekeying is the way to go. If they're worn, flimsy, or you want better security or keyless entry, replacement makes more sense.
How long does rekeying take?
Most standard cylinders take roughly 10 to 20 minutes each, so a typical home with a front door, back door, and garage entry is often done within an hour.
Can a locksmith install a smart lock I already bought?
Absolutely. They'll confirm the lock fits your door prep, handle any modifications, mount and align it, and walk you through codes and app setup.
Do you set up master key systems for rentals and businesses?
Yes. Independent locksmiths in our network build master and sub-master systems for landlords, property managers, and businesses, and can add restricted keyways for tighter key control.
Will the locksmith ask for ID before changing my locks?
They should. Responsible locksmiths verify residency or ownership with an ID, lease, or utility bill before rekeying or replacing locks, which keeps strangers from doing the same to your home.
