The OBD II Port Lock is a key-operated anti-theft device built for Ford, Chevy, Ram, and GMC truck owners, including hard-working 6.7L Cummins, 6.6L Duramax, and 6.7L Power Stroke diesel pickups. An unprotected OBD-II port lets a thief plug in a scan tool in seconds, steal driving data and trouble codes, clone a key, or reprogram the ECU. This lock's keyed aluminum housing physically blocks the diagnostic port, and only someone with the matching security key can remove it — no special tools, wiring, or vehicle modifications required. It fits any standard 16-pin OBD-II port on gas vehicles from 1996 and diesel vehicles from 2008 onward. Read on for full fitment, step-by-step installation, troubleshooting, and maintenance guidance.
