Better check first if your alarm sounds at all or not(let a window open, lock, reach in with your hand and wave or open the door... be prepared with the fob to unlock if it sounds), btw are your horns working first of all?.... cos i have the feeling it doesnt sound and your problem was a triggered alarm... that procedure which worked for you and the man who posted it IMO it's a coincidence cos it has no technical basis at all, a kinda "whichcraft" which can't be explained and AFAIK no such built in protocol was made by LR whatsoever... though i can accept that LR works in mysterious ways
