In the middle of the night (1 a.m.), the Pilot's alarm started to go off. I thought it was someone was breaking into it so I checked out the window to see before pressing the key fob to deactivate the alarm. Coast was clear so I pressed the key fob and it turned off. 30 minutes later the Pilot did the same thing so I turned off the alarm again and went outside to check that all of the doors were completely closed. Everything was completely closed. One hour later it went off again, but once I pressed the key fob to turn off the alarm it didn't work. I kept pressing to see if it would work and nothing did. The alarm kept going and going until it stopped on its own. I then proceeded inside to see if the key fob could have been the problem to change the battery. I was in the process of changing it when the alarm went off again. I then finished putting the new battery on the key fob and pressed it to deactivate the alarm and no luck. Ran outside (keep in mind it's the middle of the night and I was pretty sure my neighbors were getting upset from the noise), I put the key shank in the door to open the Pilot and then the alarm turned off. Took it to service and they stated that it was some sensor to the doors and windows.
