We’re Reliance Lock & Key, and our Car Key Replacement team has handled hundreds of automotive lockouts and key replacements across Shiawassee County. We know the side streets off Shiawassee Street, the parking lots near the courthouse, and the driveways in the older neighborhoods off M-71.

Why Reliance Lock & Key Is Corunna’s Preferred Car Key Replacement Company
Corunna isn’t a sprawling metro. It’s a tight, settled county seat where people know each other and word travels when a tradesperson does good work or bad work. That’s why we approach every job in Corunna the same way: diagnose honestly, quote upfront, and don’t leave until the key works. Our technicians have replaced transponder keys for Ford, Chevy, Dodge, and Toyota vehicles in Corunna driveways and downtown parking spots without towing the vehicle anywhere. We bring the programming equipment to you.
Much of our Corunna work comes from a recurring pattern: owner-occupied homes and small business owners who’ve had the same vehicle for eight or ten years, the original key is worn to a nub, and suddenly the ignition won’t read the chip. That’s a problem we see regularly in Corunna, and we solve it with on-site cutting and programming. No tow to a dealership in Owosso or Flint. No waiting a week for a mail-order key that may not program. Reliance Lock & Key handles the full replacement in Corunna, typically while you wait.

Our Car Key Replacement Services in Corunna
Transponder Key Replacement in Corunna
Most vehicles from the late 1990s onward use transponder chip keys. The chip communicates with an immobilizer in the ignition. When that chip fails or the key itself is too worn to be read, the engine won’t start even though the key physically turns. In Corunna, we replace and program transponder keys for most domestic and import vehicles on-site. A transponder key replacement near the courthouse or anywhere else in the 48817 ZIP generally runs $140 to $260 including programming.
Rekeying Vehicle Locks in Corunna
Sometimes the issue isn’t the key; it’s the lock cylinder. Door locks and ignition cylinders wear out, especially on older work trucks that spend years parked outdoors. When you’ve lost a key or someone who shouldn’t have access may still hold a copy, rekeying the door cylinder and, where applicable, the ignition keeps the old key from working. We’ve rekeyed truck and van locks across Corunna for contractors and delivery drivers who can’t afford to have a stray key floating around. It’s a service most dealerships won’t offer without replacing the entire lock assembly.
Non-Destructive Entry for Locked Vehicles in Corunna
Locked out of the car in the lot behind a downtown Corunna business or in a driveway off McNeil Street? We open vehicles with non-destructive methods that don’t damage doors, weather seals, or lock cylinders. Wedge marks, scratched paint, and bent door frames are what happen when someone uses the wrong tool; that doesn’t happen with our equipment. We treat your vehicle the way we’d treat our own, and we’ve opened dozens of cars around the Shiawassee County Courthouse and nearby residential streets without a scratch.
Worn Ignition and Key Extraction in Corunna
Older vehicles in Corunna, particularly work trucks with high mileage, get stuck keys and broken key fragments in the ignition. The freeze-thaw cycle that affects door frames also gets into ignition cylinders through years of winter salt residue. We extract broken keys and worn pin-and-tumbler cores without replacing the steering column, then we cut and program a fresh key so the same failure doesn’t repeat right away.

Trusted Brands We Service in Corunna
Reliance Lock & Key is qualified to service locks and keys across the full spectrum: Kwikset and Schlage for residential work, Yale and Baldwin for architectural hardware, and restricted high-security systems like Medeco and Mul-T-Lock that most general locksmiths can’t touch. That same depth carries into automotive work. We don’t just handle the easy Chevy and Ford keys; we work with vehicles that have aftermarket security, older transponder formats, and unusual keyway profiles. When we come to Corunna, we bring key blanks for most major makes, programming tools for common chip formats, and the pinning kits needed to rekey older cylinders including mortise locks on century-old storefronts.
Common Car Key Replacement Problems We See in Corunna Homes
- Worn ignitions on older pickups and fleet vehicles. Corunna has a high proportion of long-owned work trucks. When a truck’s ignition cylinder wears down, a brand-new transponder key may still fail to read. We diagnose whether it’s the key or the cylinder before cutting anything new so you don’t pay for a key that won’t work.
- Freeze-thaw warped door frames affecting lock alignment. Michigan winters and humid summers make door frames shift. This matters for keypad entry and smart lock systems, which fail to seat the latch if the strike is off by a fraction of an inch. Seasonal adjustment is often the fix before replacing any key or cylinder.
- Obsolete mortise lock cylinders in older downtown buildings. We see storefronts and offices near the Shiawassee County Courthouse with original mortise locks that date back fifty years or more. These use custom pinning kits that not every locksmith stocks. We do. That means rekeying or key replacement happens in one visit, not two.
- One-key households with only a worn original. By the time a Corunna vehicle owner loses their only key, that key was already badly worn. We recreate the key from the door lock or ignition code when no original exists, then test the new key against all cylinders before we call the job done.

FAQs – Car Key Replacement in Corunna
Yes. We regularly replace and program keys for older pickups and vans parked around the Shiawassee County Courthouse and Shiawassee Street. We come to you, cut the key on-site, and program the transponder without moving the vehicle. The uneven lot surfaces and older truck cylinders don’t slow us down. Call (855) 341-7491 for a time window.
We can usually extract a stuck or broken key without replacing the ignition or damaging the steering column. We do this on-site in Corunna using extraction picks and lubricant that won’t leave the cylinder gummed up. If the ignition core itself is worn beyond repair, we’ll tell you honestly and give you a replacement cost before any work starts.
Yes. We work with vehicles that have aftermarket keyless entry, smart lock systems, and keypad modules. The issue in Corunna is often alignment: freeze-thaw cycles shift door frames, which throws off the latch alignment and makes the lock think it’s not seated. We’ll diagnose whether it’s the key, the module, or the alignment, then fix the actual problem. We don’t sell you a new key if it’s not the key.
Cold winters and humid summers cause metal to expand and contract. In Corunna, that translates to ignition cylinders that bind in February and door locks that refuse to turn after a thaw. It also makes door frames shift, which affects electronic locks. We factor that seasonal wear into our diagnosis, so we’re not just replacing a key when the real issue is a cylinder or strike that needs attention.
We handle most major makes on-site: Ford, Chevy, GMC, Dodge, Jeep, Toyota, Honda, Nissan, and many imports. We carry blanks for a wide range of keyway profiles and have programming equipment for the common transponder formats. If your vehicle has a less common chip system, we’ll tell you up front and give you options. Call (855) 341-7491 with the year, make, and model for a quick answer.
