You just got the keys to your new home. Feels good. But here’s the thing — you have no idea how many copies of those keys are floating around out there. The previous owners, their family members, old neighbors, a dog sitter, a contractor who never returned them. In Louisville, this is one of the first practical questions new homeowners face, and most people either overthink it or skip it entirely.
Bowles Locksmith Service Louisville has been helping Jefferson County homeowners sort this out for over 31 years. Here’s what you actually need to know.
Should I Rekey or Replace My Locks After Moving into a New Home in Louisville?
Rekey your locks unless those locks are damaged, outdated, or you want to upgrade your security hardware. That’s the short answer, and it applies to most new homeowners.
Rekeying means a qualified locksmith adjusts the internal pin tumblers inside your existing lock cylinder so that the old keys no longer work. Your lock stays in place. Only new keys — the ones cut during the service — will operate it. The result is the same as changing the lock from a security standpoint: every previously existing key becomes useless. The locks themselves, assuming they’re in decent condition, function just fine afterward.
Replacing locks makes sense in specific situations: the existing deadbolts are worn, the mechanisms are stiff or failing, the hardware doesn’t meet your security standards, or you’re upgrading to a smart lock or high-security grade. The ANSI/BHMA grading system rates residential locks on Grade 1 through Grade 3 — Grade 1 being the strongest. If the locks on your new home are Grade 3 or ungraded, replacing them is worth considering alongside the rekey.
For most Louisville homeowners buying a previously occupied house, rekeying is faster, costs less, and solves the actual problem — which is unknown key history, not broken hardware.
What Happens During a House Lock Rekey in Louisville?
A residential locksmith removes the lock cylinder, disassembles it, swaps out the key pins for a new set that matches a different key cut, and reassembles everything. The whole job on a standard home — front door, back door, and a side entry, for example — typically takes under an hour for an experienced technician.
One thing worth knowing from real field experience: older Louisville homes, especially those built in the 1960s through 1980s in areas like Shively, Okolona, or Valley Station, often have mix-and-match hardware from different manufacturers. Doorknobs from one brand, deadbolts from another. A technician can sometimes key those to the same key — called “keying alike” — so you’re carrying one key instead of four. That’s a detail worth asking about when you schedule the service.
When Replacing Locks Makes More Sense?
Swap the hardware instead of rekeying it if you notice any of the following:
The deadbolt has visible wear — the bolt doesn’t throw cleanly, the cylinder feels loose, or there’s rust or corrosion around the mechanism. A rekeyed lock that’s mechanically compromised is still a compromised lock.
The locks don’t have a deadbolt at all. Plenty of older homes in Louisville still have knob-only entry locks on exterior doors. Knob locks alone offer minimal resistance. A deadbolt should be the primary lock on every exterior door.
You want keyless entry. Smart locks and keypad deadbolts have gotten significantly better and more reliable in 2026. If you’d rather grant temporary codes to a contractor or house cleaner instead of cutting physical keys, the move-in is a natural time to make that switch. A residential locksmith can install and configure those for you rather than fumbling with app-based setups that assume no prior installation experience.
The ALOA Security Professionals Association — the main professional organization for locksmiths — recommends homeowners check both the quality of their existing hardware and the history of key distribution when evaluating security after a home purchase. That two-part check is exactly why calling a locksmith is smarter than just running to a hardware store.
Don’t Forget These Spots
New homeowners often rekey the front door and stop there. Here’s what gets missed:
Garage entry door. If your garage is attached, the door between the garage and your living space is just as important as the front entry. It’s often hollow-core and under-secured.
Basement or cellar doors. Older Louisville homes with walk-out basements frequently have exterior doors that weren’t part of the main lockset purchase when the home was built. Check them.
Sliding patio doors. These use different hardware — a locksmith can assess whether the existing bar lock or secondary latch gives you adequate security.
Mailbox and outbuilding locks. Lower priority, but if the previous owners had a locked shed or detached garage, those keys were almost certainly on the same ring.
A Quick Note on Kentucky Law
Kentucky does not require locksmiths to hold a state-issued license, which means the quality of residential locksmith work varies depending on who you hire. Look for professional association membership, real local reviews, and a track record. The Better Business Bureau is a reasonable starting point for checking a company’s complaint history. Bowles Locksmith Service Louisville holds an A+ BBB rating, which reflects their standing in the Louisville, Southern Indiana, and Western Kentucky region.
You can read what Louisville homeowners have said about the service on the client reviews page — specific feedback from actual jobs is more useful than general ratings.
Other Security Services Worth Considering at Move-In
If you’re already having a locksmith out to rekey, it’s a good time to assess your full home security picture. Residential locksmith services often include safe installation or assessment. If you’re storing important documents, jewelry, or other valuables, a home safe bolted to a floor joist or wall stud is a practical addition. A qualified technician can advise on placement during the same visit.
For those who also need commercial lock work — say, you’re a business owner who just moved into a new space — commercial locksmith services cover master key systems, access control, and door hardware on a different scale than residential work.
