Well I don't know who to thank, but one of you guys sent me an angel. John-sussex, did you send me one of those UK Rover angels?
Once I got the dreaded immobilized engine message, I gave up and started looking for a place to tow my Rover. The only way to stop the alarm at one point was to disconnect the battery. As I sat and called every shop, which are all closed because it is the weekend, I kept the battery disconnected. About an hour later I reconnected the battery and the I heard the doors unlock. I jumped in the truck so quick and stuck the key in the ignition just incase the truck decided to go into lock mode again. I turned the key and it started. There were no faults showing up and my key fob somehow got synced again.
Now that I got back home, I guess I should order that drivers door latch and replace it. I read that the new latches are crap, but I'm not sure what else to do except buy new because I don't know where else to get one. I figured I'd pick on up from Atlantic British. I'm debating if I should take my chances and replace the latch myself or if I should take it to a shop just in case anything strange happens while replacing. I'm leaning toward replacing it myself since I'm feeling lucky after todays stranding. If all goes well when I replace the latch, I assume that I shouldn't need to worry about needing to reset anything with the Rover Test Book system. Is this a safe assumption?
