I think you should try it all again, perhaps change the order. Because I purchased a Chinese copy obd ii device I also had a couple attempts that didn't work as intended. Eventually it did work. I suggest keeping at it.Ok so I read this thread and was hoping this would work. But I tried it yesterday and it didn't. Here are the steps i did, please take a look and see if I did something wrong.
Background: 2013 Focus SE Hatch, bought for my daughter for college, only came with one key and it was a mykey. I purchased the elm hs/ms-can device from Amazon and downloaded Forscan and Focccus. Tried Forscan first on car to make sure things communicated and everything was fine.
Steps I did:
1, Pluged ELM device into obd port, turned key to on and loaded focccus. Device left in HS-CAN position.
2, Had focccus read BCM, saved baseline to file.
3, Changed mykey input from 2 to 0. Wrote to BCM.
4, Turned car off, waiting a min, disconnected elm and turned key back to on.
5, Turned car on, said "Normal mode" on screen but still recognized mykey key and still had limitations.
6, Checked settings and it still showed 1 mykey, 1 admin key. So based on setting it to 0, the BCM didn't remove the feature.
7, Plugged ELM back in and loaded Focccus, read BCM, confirmed it was set 0.
8, Set mykey flag to 1, wrote to BCM. Repeated step 4.
9, Same as step 5. No change.
10, Did step 7 again, loaded baseline bcm program and put back loaded back to BCM.
So does anyone see anything I did wrong? I was using this a trial run because I wanted to see if Focccus worked on her car because I want to do the fog lamp install because I have the fuse 75 with a 15 amp in it.
Also, buy some extra key fobs on eBay and find a local locksmith with the computer key programmer.
