Covering O'Fallon From WingHaven to Old Town

O'Fallon has grown fast, and a lot of our work there is on newer homes and newer vehicles. That means smart locks that stopped pairing, keypad deadbolts with a forgotten code, and push-button smart keys for late-model SUVs and trucks. Our vans carry the programming equipment to handle those jobs on-site, instead of sending you back to the dealer.

We also take plenty of calls from Old Town O'Fallon, the ballfields and sports complexes on the city's east side, and the office parks near Hwy 364 and I-64, where a lost fob can stall a whole workday. Call with your location and we'll quote the job before we roll.

O'Fallon Locksmith FAQ

Can you make a smart key for my 2019 Toyota Highlander if all keys are lost?
In most cases, yes. We supply and program a new smart key for the 2019 Highlander at your O'Fallon location and cut the hidden emergency blade to match your locks. Call with your VIN and we'll confirm the exact key and price before we come out.
I lost the only key to my 2017 GMC Acadia. Do I need to tow it to a dealer?
No. We can generate and program a new key for the 2017 Acadia right where it's parked in O'Fallon, which saves the tow and the wait for a dealer appointment.
Can you reset or reprogram a keypad smart lock in a WingHaven home?
Yes. We reset and reprogram most Schlage, Kwikset and Yale keypad and smart locks, change codes after a move, and replace units that have failed. If you'd prefer a simple keyed deadbolt, we can swap that in too.
Do you make keys for a 2018 Jeep Wrangler JK or JL?
Yes. We program keys for both the 2018 Wrangler JK and the newer JL. The JL has an added security gateway module, and we carry the equipment needed to program keys through it.
Can you meet me at the ballfields or sports complex in O'Fallon if I lock my keys in the car?
Yes. Weekend tournament lockouts are common for us. Tell us which lot or field entrance you're near so our tech can find you quickly.
How much does it cost to rekey a house in O'Fallon?
Cost depends on how many locks you have and what brand they are. We quote a firm price by phone once we know the number of doors, and that price doesn't change when the work is done.
Can you add a spare key fob for my 2020 Kia Sorento?
Yes. For Kia models we obtain the immobilizer PIN through NASTF-registered access and program the new fob at your vehicle. Adding a spare while you still have a working key costs less than waiting until it's lost.
Do you rekey offices along Hwy 364 or I-64 after an employee leaves?
Yes. We rekey office doors so former employees' keys stop working, and we can design a master key system so managers carry one key while staff only open what they need.
My key broke off in the ignition of my 2012 Ford Fusion. Can you help?
Yes. We extract the broken piece without damaging the ignition, then cut and program a new transponder key so you can drive away — all at your O'Fallon location.
Can you make keys for a 2015 Chevy Tahoe with a worn-out key?
Yes. If the key is worn, we can cut a fresh key to the original factory code instead of copying the wear, and program it to the truck so it starts reliably.
Do you serve both 63366 and 63368 in O'Fallon?
Yes, both ZIP codes, plus nearby Dardenne Prairie, Lake St. Louis and St. Paul. Regular hours are 6 AM to midnight daily, and our emergency line is answered 24/7.
