Why Our Locksmith Referral Line Gets the Call
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. We connect callers with independent locksmiths who do the job properly the first time.

Licensed & Insured Locksmiths
You're connected with licensed and insured independent professionals. Ask for their license on arrival; a legitimate locksmith carries it and won't mind showing it.
Upfront, Flat-Rate Quotes
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
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.
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. Ask about keying every exterior door alike so one key opens them all.
- New-home rekeys
- Keyed-alike setups
- Worn cylinder replacement
Deadbolt and Smart Lock Installation
What actually stops a kick-in is a Grade 1 or Grade 2 deadbolt with a one-inch bolt throw and a strike plate screwed deep into the framing, not just the jamb. 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 Keying for Landlords and Businesses
A master key system gives each person access to just the doors they need, while owners and managers carry a single master. 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. 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 Cylinders
Basic pin tumbler cylinders are vulnerable to bump keys and picking. 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
Locksmiths also cut keys from codes, duplicate high-security keys, handle safe openings and combination changes, and swap out mailbox, desk, and cabinet locks.
- Key duplication and code cutting
- Safe openings and combination changes
- Mailbox and cabinet locks

Real Stories From Real Callers
After closing on our home, I realized I had no clue who still had keys to it. 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 Affton, MO
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.
Our rear exit device failed a fire inspection and we had a week to fix it. The commercial locksmith replaced the worn latch, adjusted the closer so the door actually latched, and had us passing reinspection before the deadline.
I was ready to buy a new deadbolt because ours barely turned. 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.
Our office had gone through a lot of staff over the years, and nobody knew where all the keys were. 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.
Answers to Common Locksmith Questions
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?
Rekey when the hardware is in good shape and you just need old keys to stop working. Replace when locks are worn, cheaply made, damaged, or when you want an upgrade like a Grade 1 deadbolt or a smart lock.
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.
