So for all you guys that have added tunes to your Explorer or modified modules via Forscan, do any of you have a OBD port lock installed? I've seen covers for them before but I would like another layer of protection. Basically I added remote start, navigation, and a few other changes to our Ex and if I ever take it in for any service I want to know they wont mess with the computer without consulting me first and erase all my changes for no reason. A google search came up with a few: Auto & Truck Accessories | Marysville | BEM Auto This one looks nice, compact, not over priced, however I don't see how it locks onto the port though and the key doesn't look unique. AutoCyb – AUTOCYB: Driving Freedom This one looks pretty nice too. A little bigger but the key looks more unique and its borderline expensive. I'm wondering if anyone has experience with either of these or any other OBD lock device out there?
