Have a 2000 2x4 LT with the 5.9 liter...little over 220K miles. Engine and transmission are great, but i'm having this problem when I try to unlock the car with the fobs, the alarm goes off and the only way I can stop is is by disconnecting the battery. Not really to worried about getting stolen, but I need to find a way around to disable all the security stuff without disabling the car. Help! Same thing happens with just a key start.
