Who they are
Four specialties, one focus
Stone Fort Motors doesn’t do everything — they focus on the specialized work most shops can’t, using factory-grade diagnostic and programming equipment. Their four specialties are automotive diagnostics, module programming, smart keys, and automotive locksmith work.
Today’s vehicles don’t just need a cut key — they need a key programmed and paired to the immobilizer and modules. Stone Fort Motors handles smart, proximity, and push-to-start key programming, plus module flashing and setup after replacement, across most modern makes.
They’re also one of the few shops that can unlock most GM radios that become VIN locked after a replacement, module swap, or other vehicle work — explaining what your vehicle needs before service begins.

Automotive Diagnostics
Computerized scanning, fault-code analysis, and drivability diagnosis to pinpoint check-engine, electrical, and module issues — fast and accurate.
Module Programming
ECM, PCM, TCM, and body-control module programming, flashing, and setup after replacement or software updates with factory-level equipment.
Smart Keys
Programming and replacement of smart, proximity, push-to-start, and transponder keys for most makes. New keys cut and paired to your vehicle.
Automotive Locksmith
Ignition repair and replacement, lock service, and broken-key extraction. Lock and key work done right — without damaging your vehicle.

NASTF Vehicle Security Professional
