Thanks for reply, really appreciate it.
The alarm/lights does stop with the key. Not sure I have a panic button on my fob (just lock and unlock buttons).
I noticed the box bolted behind the pump (wondered what that was).
I will definitely disconnect (wish I hadn't replaced boot carpet/trim. what a *** of a job to remove)
The only issue with pulling the fuse is that I can't get my key all the way in the door hole and so does lock/unlock. Guess there may be a bit of snapped key in there (I only have 1 key). Another job to do.
