I am having a problem with my 2002 RR in that the alarm system disables the vehicle in very hot weather (the vehicle has been parked in the sun for over 4 hours). The alarm system activates and I am not able to turn over the ignition without the siren activating. Has anyone else had this issue with interior heat of the vehicle causing the alarm system to disable the vehicle. I live in Texas and the summer weather can reach over 100 degrees daily. My only fix to this point is to open the hood and disengage the battery, with the alarm blaring I might add, to shut down the system and disable the alarm. Then the vehicle operates properly and the ignition turns over. I could use all truly helpful suggestions (I.e. moving out of Texas is not an option!). Thank you.
