Hi im having trouble with my alarm and radio on my truck. all started when I changed the battery on my 05 Grand Cherokee Limited. After I was unable to activate alarm with my remote and my radio does not turn on. I know the alarm works because I locked it manually left a door open alarm turned on by itself. I opened the door and alarm started going off was able to turn truck on with my key. Does anyone know where to start to fix problem. which fuses to check and location of each one. I replaced battery in remote and put in the old car battery. if anyone has any tips or advice it will help. Don't know if i may have caused a surge by putting in a battery that was to strong.
