Why Callers Choose SND Heating and Air Conditioning for Locksmith in Fairfax, SC
A lock is only as good as the person who installed it. A cylinder pinned out of tolerance starts sticking within months, and a deadbolt held by half-inch strike screws gives way to one solid kick. Our referral line connects you with independent locksmiths who take that precision seriously.

Licensed & Insured Locksmiths
Calls go to licensed and insured independent locksmiths. Where your state licenses locksmiths, ask to see the credential and a business ID before work starts.
The Full Price First
Locksmith scams usually start with a low phone price that triples at the door. Network locksmiths quote the whole job, including the trip charge, hardware, and labor, before any work begins.
Same-Day Service
We match you with an available locksmith nearby, which makes same-day rekeys and installs common.
Fully Stocked Vans
Network locksmiths carry pinning kits, plug followers, key machines, and door-boring jigs, along with Grade 1 and Grade 2 hardware.
After years of handling these calls, we've noticed a pattern: the lock usually isn't the real culprit. A sticky deadbolt often traces back to a sagging door, a lock that seizes in cold weather typically needs dry graphite instead of spray oil, and a key that has to be jiggled is usually worn down. Experienced locksmiths look at the door, frame, and hinges before recommending new hardware. One more tip: have new keys cut from code rather than duplicated from an old, worn key, so the replacement works as smoothly as the original.

From a single sticky deadbolt to a forty-door master key system, these are the jobs independent locksmiths in our network handle every week.
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. Locksmiths also install and program keypad and smart locks, bore new doors, and fix bolts that drag because the strike is misaligned.
- Grade 1 and Grade 2 deadbolts
- Smart and keypad lock setup
- Strike plate reinforcement
Master Keying for Landlords and Businesses
Landlords and business owners lose control of their keys faster than they think. A master key system lets each tenant or employee open only their own door while managers carry one key for everything. The locksmith designs it from a bitting chart and can add restricted keyways so copies can't be cut at a hardware store kiosk.
- Master and sub-master systems
- Restricted keyways
- Rekeys after turnover
Commercial Door Hardware
Storefront and office doors take a beating, and failed hardware can mean code violations along with security gaps. Work includes mortise lock repair, exit device service, aluminum storefront deadlatches, closer adjustment, and lever trim that meets ADA requirements.
- Exit devices and panic bars
- Mortise locks and storefront latches
- Door closer repair
High-Security Lock Upgrades
Basic pin tumbler cylinders are vulnerable to bump keys and picking. High-security cylinders use secondary locking elements, drill-resistant hardened inserts, and controlled key blanks. They make sense for side doors out of view, home offices, and businesses holding valuable stock.
- Bump- and pick-resistant cylinders
- Drill-resistant inserts
- Controlled key duplication
Key Cutting, Safes, and Specialty 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

What Callers Say About Their Locksmith Visit
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 Fairfax, SC
I own a fourplex and was tired of rekeying everything every time a tenant moved out. 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?
Each locksmith sets its own rates, normally a trip charge plus a set price per cylinder. Because no new hardware is needed, rekeying is usually the budget-friendly option, and the full price is quoted before any work begins.
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?
Plan on about 10 to 20 minutes per lock. An average house with three or four exterior locks usually wraps up in under an hour.
Can a locksmith install a smart lock I already bought?
Yes. The locksmith checks your door's thickness, backset, and bore size, makes any adjustments, installs the lock, aligns the strike, and helps you pair the app or set user codes.
Do you set up master key systems for rentals and businesses?
Yes. Calls are routed to locksmiths who design master key systems from a bitting chart, often with restricted keyways that prevent unauthorized copies. They work for apartment buildings, offices, schools, and retail spaces.
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.
