I have had this happen twice already and have not been able to shut it off. We have pressed everything on the remote.... This last time it continued for several minutes before we were able to finally shut it off. We opened the door, which in turn set off the actual car alarm, and put the key in the ignition. Once we took the key out of the ignition and pressed the panic button it stopped. Not sure if it was a coincidence or not. I am actully going to bring this to the dealers attention to see if a TSB has been issued for this problem.
