Losing your car keys or breaking an ignition cylinder isn’t just an inconvenience—it stops your day cold. At A Complete Lock And Key Service, we provide rapid, mobile automotive locksmith services throughout St. Louis, Chesterfield, Maryland Heights, and South County.
Unlike dealerships that require you to tow your vehicle to their lot and wait days, our fully equipped mobile vans come to you. Whether you drive a domestic Ford or Chevy, or a foreign Honda or Toyota, our certified technicians can cut and program new keys on the spot, often for significantly less than dealership prices.
Car Key Replacement & Transponder Programming
Lost Your Only Key? We Can Make a New One From Scratch.
Modern vehicles use sophisticated security systems. You need a locksmith who understands the technology behind the plastic head of the key. We specialize in:
Transponder Key Programming: Most cars made after 1995 require a “chip key” to start the engine. We stock and program transponder chips to communicate with your car’s immobilizer system.
Key Fob Replacement: We supply and program remote head keys, keyless entry fobs, and “push-to-start” proximity smart keys.
Laser Cut Keys: We have high-precision milling machines to cut “sidewinder” and high-security laser keys used by newer models.
Mobile Emergency Car Lockout Service
Locked Keys in the Car? Don’t Use a Coat Hanger.
Trying to pry your door open can damage weather stripping, scratch paint, or disable airbags. Our professional car lockout service uses specialized tools (like Lishi picks and air wedges) to gain entry without damage.
Zero-Damage Entry: We unlock doors safely.
Trunk Unlocking: Locked your keys in the trunk? We can generate a key to open it or release the latch.
Rapid Response: Serving Town and Country, Creve Coeur, Ladue, St. Charles, and the City/County of St. Louis with fast ETAs.
Ignition Repair and Replacement
Key Won’t Turn? Key Broke Off in the Ignition?
Sometimes the problem isn’t the key, but the lock itself. Wafers inside the ignition cylinder can wear down or jam, leaving you stranded.
Ignition Rebuilding: We can often disassemble and repair your existing ignition lock cylinder, matching it to your current key so you don’t need two different keys for the door and ignition.
Broken Key Extraction: If your key snapped off inside the ignition or door lock, we use specialized extraction tools to remove the debris before cutting a fresh key.
Ignition Replacement: If the damage is severe, we install high-quality replacement cylinders.
