Rekey, Repair, or Change Locks? A Central PA Home Guide
"I need a locksmith" usually means one of three totally different things. Old keys floating around from before you moved in. A lock that fights you every morning. A deadbolt you flat out don't trust anymore. Pick the wrong fix and you've wasted money. Here's how to tell them apart.
Just moved in? Rekey first.
New house, same old keys. Nobody thinks about it until 11pm, staring at the deadbolt, wondering who else has a copy. Past owners. The contractor who redid the kitchen. A neighbor who used to water the plants. You don't know. You can't know. That's the whole problem.
Rekeying fixes it without touching your hardware. Open the cylinder, swap the pins, every old key stops working. Your deadbolts and handles stay exactly as they are. Most homes run 3 to 6 exterior locks. One visit, done.
Rekey or replace? People mix these up constantly.
Rekeying changes what key opens the lock. Replacing swaps the lock itself. That's it, that's the whole distinction. Deadbolt turns smooth, looks fine, just needs new keys? Rekey it. Don't spend more than you have to. Damaged, decades old, or you just want a different finish? That's a replacement.
A sticking lock isn't automatically dead
Hard to turn. Catches halfway. Sticks every time it's humid out. None of that means the lock is finished. Usually it's a worn or misaligned pin, sometimes a stiff strike plate. A locksmith can figure out which on the spot, and a lot of the time it's a quick repair, not a teardown. Worth checking before anyone assumes the whole unit needs to go.
Lost a key, or had a break-in? Different urgency.
Actually lost, not just misplaced somewhere in the couch cushions? Rekey now. Don't wait a week hoping it turns up. A break-in attempt, even a failed one, is a different call. Change the affected lock outright. The hardware itself may already be weakened, and a rekey doesn't fix that.
Smart locks skip this whole question
Code or app instead of a physical key, so there's nothing to rekey. Most models still keep a physical backup key for dead batteries or a power outage, and that cylinder rekeys the normal way if you want it controlled too.
What the visit looks like
A technician walks the exterior with you and confirms what actually needs attention. Rekeying, repair, replacement, sometimes all three on one house. Upfront quote first, nothing gets touched before you approve it. Typical home wraps in a single appointment. Just moved in anywhere across Dauphin, Cumberland, or Lebanon County? Call (223) 240-3505.
Frequently asked questions
The old owner seemed trustworthy. Do I still need to rekey?
Yes. It was never really about them. It's the contractor, the dog walker, the ex-tenant who might still have a copy. Rekeying closes that loop.
Rekey vs. changing locks, what's actually different?
Rekey: same hardware, old keys stop working. Change locks: the hardware itself gets replaced. Working deadbolt, just new keys, rekey. Damaged or outdated, replace.
Can a sticking lock get repaired instead of replaced?
Often. Usually a worn or misaligned pin, not a dead lock. A locksmith checks it on site and repairs it right there more often than not.
How long does rekeying take?
One visit. Most homes have 3 to 6 exterior locks, all handled in that same appointment.
Do smart locks need rekeying at all?
Not for the app or code side, no. Got a physical key backup on yours? That cylinder still rekeys like any normal lock.
