Just bought an 03 Mustang from an auction and took it on a trip. The anti-theft system kicked in and I had to disconnect/reconnect the battery to get it working again. That worked a few times and I thought it would continue to work until I got home where I would get it looked at.
Unfortunately it stopped working altogether and I had to tow it to a dealership. I asked them to disable the anti-theft system altogether but they tell me that's not an option and I have to fix it. A call to my regular mechanic who I trust confirmed that they were telling the truth.
However, I've seen webpages talking about 'tunes' and 'tuners' (I have no idea what that is though) you can get to disable it and referencing Mustangs specifically and I'm pretty sure one page was even specifically talking about the '03 Mustang.
So my question is: Is there a way to just disable the anti-theft system? I'm not worried about anyone stealing my car but I definitely don't wanted to get stranded several states way from home ever again so if there's a way to do it I'd sure like to know.
