After removing positive battery terminal first by mistake car turns over won't start. Tried remove battery cable 10 minutes left key on removed anti theft fuse and nothing. Took both terminals off hooked jumper cable between the 2 hooked all back up and nothing. Cranks good no start. Had check engine port tested mechanic say security system needs reset. 2 hours to nearest dealer anyway to not have it towed?

Unfortunately, it sounds like this is a security lock out and will require it to be reset and not just an activation. The attached guide goes through how to deactivate it but this needs a reset which is different. Basically it thinks someone was trying to steal it so it needs someone with a tool to tell it everything is okay now.

You don't necessarily need a dealer, just someone who has the OEM scan tool. Many shops around have this tool, you just need to find them. I would suggest spending some time calling around before you have it towed.

Also, did they give you any specific codes when they scanned it? That may help determine if anything else can be done. Thanks
