Most locksmith calls in Corunna come down to one question: can you rekey this without replacing the whole lock? The answer is usually yes. Squire Locksmith has served Corunna since 2015, and we’re set up for exactly the hardware this town actually has – older Schlage and Kwikset cylinders on mid-century homes, worn mortise locks in downtown storefronts near the Shiawassee County Courthouse, and weathered deadbolts on farmhouse doors that have seen forty Michigan winters. Call (866) 361-1189 when a lock stops behaving, and we’ll walk you through the fix before anyone rolls a truck.
Why Corunna Homes Are Different
Corunna’s housing stock runs older than what you’ll find in the newer subdivisions around Owosso or Flint. In town, you’ve got pre-war and mid-century single-family homes, many still carrying their original mortise locksets and brass cylinders. Out in the surrounding township, it’s farmhouses on well-and-septic parcels, with detached garages, pole barns, and shed doors that take outdoor-grade hardware and a lot of weather. That mix means we routinely service locks that a big-box installer would call obsolete – and we’d rather repair and rekey them than tell you to buy something new that won’t fit the door prep.
Freeze-thaw cycles are the hidden adversary here. Exterior deadbolts seize when moisture gets into the cylinder and freezes. Door frames swell in humid summers and shift as the ground moves, which throws latch alignment off by fractions of an inch – enough to make a key turn hard or not at all. Add winter ice and snow, and you get the two most common Corunna calls we answer: a lockout from a frozen cylinder, or a key snapped off in a cold, corroded lock. Most of these jobs are rekeys and cylinder services, not full replacements, which is why rekeying is the core of what we do in this town.
Styles & brands we work with
Our Main Corunna Services
Two services account for most of the calls we take from Corunna homeowners and drivers. Both are covered here in depth on their own pages.
Car Key Replacement in Corunna
Losing a car key in Corunna often means standing in a parking lot off M-21 or in a driveway off a gravel township road with no spare and no easy way to get one. We cut and program replacement keys on-site for most makes – no dealership detour, no tow. Michigan winters make this worse: keys get dropped in snowbanks, left in coat pockets that go through the wash, or snapped off in frozen door locks. We handle transponder keys, fobs, and traditional metal keys, and we’ll come to your location in the 48817 area. See the full breakdown on our Car Key Replacement in Corunna page.
Emergency Locksmith in Corunna
Locked out of the house on a January night in Corunna, or standing next to a locked car with the engine running in a downtown lot – those are the calls we’re built for. Emergency locksmith work is a core service here, not an add-on. We carry a full van inventory for Schlage, Kwikset, and Yale hardware, plus the tools to open older locks without destroying the door. Response runs fastest in the 48817 corridor and along M-21, with rural township calls taking longer depending on road conditions. Details are on our Emergency Locksmith in Corunna page.

Rekey Locks in Corunna
Rekeying in Corunna is almost always the right move before replacing hardware, because the houses and storefronts here were built when locks were made to be serviced. A rekey changes the internal pins so the old key stops working and a new key takes over – same lock, new access. For a mid-century home in town where every door still has matching original Schlage cylinders, or a farmhouse where a former owner’s key might be floating around with a neighbor or a hired hand, rekeying resets security without ripping out doorsets that have settled into their frames. We keep pin kits for Schlage, Kwikset, Yale, and Medeco on the truck, so a full-house rekey in Corunna is usually a same-visit job. Learn more about the service on our Rekey Locks page.
Lock Rekey
Signs you need it
You’ve just bought a house in Corunna, a tenant moved out, or a key went missing and you can’t account for every copy.
What it costs in Corunna
A standard lock rekey in Corunna typically runs $20 – $45 per lock cylinder for the labor, with new keys included.
How we do it
We open the cylinder, swap the pins to match a new key, and test the lock through several throw-and-retract cycles before we hand you the keys.
Keyed Alike
Signs you need it
You’re carrying four different keys for four different doors and want one key that turns every lock on the property.
What it costs in Corunna
Keying locks alike in Corunna is priced per cylinder, usually $20 – $45 each, with no surcharge for matching multiple locks to the same key.
How we do it
We pin each lock’s cylinder to a single key code, so one key operates the front door, back door, garage service door, and any outbuilding we service at the same visit.
What Rekey Locks Costs in Corunna
| Item | Typical range in Corunna |
|---|---|
| Standard lock rekey (per cylinder) | $20 – $45 |
| Keyed alike (per cylinder) | $20 – $45 |
| Service call during a rekey visit | $50 – $90 |
Those are our real numbers for Corunna. The range covers the difference between a simple Schlage or Kwikset cylinder and a high-security Medeco that needs specialized pins and tighter tolerances.
How much does it cost to rekey a house in Corunna?
A typical three-door house in Corunna, with one service call and three cylinders rekeyed, usually lands between $110 and $225. The exact quote depends on the lock brands on the doors and how many cylinders you want keyed alike. Call (866) 361-1189 for a firm price before dispatch.
Is rekeying better than replacing my locks in Corunna?
If the hardware still functions, rekeying is the smarter move: it keeps period-correct locks in place, costs less than new hardware, and fully invalidates every old key. We only recommend replacement when a lock is corroded, damaged, or no longer meets the security level you need. Call (866) 361-1189 and we’ll tell you honestly which way to go.
Brands We Service in Corunna
We work across Schlage, Kwikset, Medeco, and Yale – the brands most common on Corunna’s older homes and the storefronts around the courthouse. Our van stock includes pin kits, cylinders, and common service parts for all four, so most rekeys and cylinder swaps happen in a single visit. From Schlage to Medeco, we know your lock. More on our capabilities is on the our brands page.
Pricing for Locksmith in Corunna, MI

| Standard lock rekey (per cylinder) | $20 – $45 |
| Keyed alike (per cylinder) | $20 – $45 |

What pushes a Corunna job toward the top of a range is usually the distance: rural farmsteads and township roads add drive time, and a frozen or corroded lock takes longer to open carefully than a clean one. Whatever the number is, you’ll hear it on the phone before we dispatch, and that is the price on the invoice – no arrival surprises, no call-out fee tacked on after the fact.

FAQs About Locksmith in Corunna
For emergency callouts, we typically reach addresses in downtown Corunna and along the M-21 corridor within 30 to 45 minutes. Rural farmsteads and township roads add drive time, especially in winter when gravel roads are snow-covered. We’ll give you an honest ETA on the phone, not a promise we can’t keep.
No. Rekeying, changing locks, and residential lockout openings require no permit anywhere in Corunna or Shiawassee County. Commercial properties near the courthouse may have landlord or municipal lease terms that specify key control, and we’re used to working with those requirements.
Almost always, yes. Most Corunna homes have three to five entry locks, and with Schlage, Kwikset, and Yale pin kits on the van, we finish a full rekey in a single visit. High-security cylinders like Medeco may need a follow-up if specific pins aren’t in stock, though those are rare on residential property. Call (866) 361-1189 and we’ll tell you what the job involves and the exact cost before we come out.

What Corunna Customers Say
"Got me back in and the price was fair for the hour. He did arrive closer to 45 minutes than the 20 he estimated, which felt long standing outside, but he was honest that traffic was the problem."
— Megan Parker"Rekey was done properly. One of the keys he cut was slightly stiff in the back door and I had to call him to swap it, which he did without a fuss."
— Cole Walsh"Locked out at eleven at night with a kid asleep in the car. He was there in 25 minutes, had the door open in under two, and did not do the thing where the price goes up once he's standing in front of you."
— Marcy Reed
