Rekeying locks is the service Corunna homeowners call us for most often, and it makes sense once you understand the housing stock here. Most homes in Corunna date to the mid-20th century or earlier, which means original mortise locksets, worn cylindrical hardware, and decades of keys floating around. Our work in Corunna centers on bringing those older locks back to secure condition without replacing solid, well-built hardware that just needs the right attention. Call (855) 341-7491 and we’ll talk through what you’re dealing with.
Why Corunna Homes Are Different
Corunna isn’t a new-construction market. It’s a settled Shiawassee County seat where homes were built to last, and that means locks from the 1940s through the 1970s are still doing daily duty. We routinely see original mortise locksets on century-old downtown storefronts and older cylindrical locks on mid-century ranch homes. These aren’t bad locks, they’re just tired. The hardware is often solid brass or steel, and rekeying them is almost always smarter than pulling them out for cheap replacement sets.
Michigan’s climate works against door hardware here in a specific way. Corunna’s cold winters bring freeze-thaw cycles that swell door frames, and humid summers do the same. That means strikes that were perfectly aligned in October are suddenly off by an eighth of an inch in July. Deadbolts that throw smoothly in January bind in August. When we rekey a Corunna lock, we’re usually also adjusting the strike plate at the same time, because the two jobs go together in this climate.
The county seat factor matters too. Corunna’s courthouse-adjacent commercial buildings and the rental turnover that comes with being a government center mean recurring rekey and master-key work. A landlord taking back a downtown apartment or a law office cycling through staff keys needs those locks rekeyed on a schedule, not after something goes wrong.
Styles & brands we work with
Our Main Corunna Services
Most calls we get from Corunna fall into two buckets: lock rekeying, which we cover in depth below, and these two services that have their own dedicated pages.
Car Key Replacement in Corunna
Losing a car key in Corunna doesn’t mean a trip to the dealership in Owosso or Flint. We cut and program replacement keys for most makes and models, including transponder keys and fobs. Older cars are straightforward, but newer vehicles need programming equipment that we carry in our service vehicle. That means we can replace your key in your driveway on M-21 or near McCurdy Park without you towing anything anywhere. For the full picture on what we cover, see Car Key Replacement in Corunna.
Emergency Locksmith in Corunna
Locked out of your house on a January night in Corunna, or standing next to a car with keys locked inside? We respond to emergencies across the 48817 ZIP code. Older homes here often have deadbolts that were installed decades ago, and when they fail, they fail closed. You’re not getting through that door without the right tools and the right touch, which is where we come in. Emergency Locksmith in Corunna covers response, pricing, and what to expect.

Rekey Locks in Corunna
Rekeying a lock in Corunna usually means working on hardware that’s been in place since the Nixon administration, which means the job is part lock work and part patience. The freeze-thaw cycles here have shifted door frames over decades, so we’re often rekeying a cylinder and then adjusting the strike so the bolt actually throws. It’s the difference between a rekey that works and one that still sticks.
If you’ve lost track of who has a key to your front door, or you’ve bought a house in Corunna where the previous owner handed over two keys but probably had five, Rekey Locks is the service we’d point you to. We rekey the cylinders so old keys stop working, and you keep your existing hardware.
Lock Rekey
Signs you need it
You’ve bought a home in Corunna, lost a key, had a tenant move out, or you genuinely can’t remember who has copies.
What it costs in Corunna
A standard residential lock rekey in Corunna runs $50 to $120 per lock, including new keys and labor.
How we do it
We remove the cylinder, swap the internal pins to a new key code, test the new key in both directions, and reinstall the cylinder with the strike adjusted for any frame settling.
Rekey Door Lock
Signs you need it
Your key turns but the deadbolt doesn’t throw smoothly, or you want one key to work multiple doors and currently carry a keyring that jangles like a jailer’s.
What it costs in Corunna
Rekeying a door lock on an older Corunna home typically runs $60 to $130 per lock, slightly higher when we’re also realigning a settled strike plate.
How we do it
We rekey the cylinder to a new key, then adjust or shim the strike plate so the deadbolt throws cleanly without lifting the door.
What Rekey Locks Costs in Corunna
| Item | Typical range in Corunna |
|---|---|
| Standard residential rekey (per lock) | $50 – $120 |
| Rekey with strike adjustment (settled door) | $60 – $130 |
| Keyed alike (multiple locks, includes keys) | $100 – $180 |
Is rekeying better than replacing locks in older Corunna homes?
Yes. Older Corunna homes often have solid brass or steel hardware that outperforms what’s sold at big-box stores today. Rekeying keeps that hardware in service for another twenty years and costs a fraction of replacement. Call (855) 341-7491 for a quote on your specific locks.
Can you rekey all the locks in my Corunna house to one key?
We can. That’s called keyed alike, and it’s common here where older homes have three or four different keys spread across deadbolts and doorknobs. We rekey each cylinder to the same code, test every lock, and hand you as many copies as you want.
Brands We Service in Corunna
We work on the full range in Corunna, from the Schlage and Kwikset hardware on most residential doors to restricted high-security systems like Mul-T-Lock, Abloy, and Sargent. Parts for common Schlage and Kwikset cylinders are stocked in our service vehicle, so most rekeys and repairs happen in one visit. Our brands page covers the full list.
