Warnings and Buzzers going crazy!
 

I have an 02 V8 XLT with a rebuilt engine approx. 10000 miles ago. The door ajar warning is constantly going off and on while the car is driving (all doors are shut). When I shut the car off and take the keys out of the ignition the "keys left in the ignition" alarm bell stays on and will not turn off. If I lock the vehicle the theft alarm will honk the horn.
Has anyone had this issue and know the fix?
