Please help i cant even drive the truck because of the alarm going off all the time!!

 

Welcome to the board!

We need a bit more info on your alarm. Is if factory or aftermarket. What condition is your truck battery in - (low power causes lots of alarms / wierd happenings). Have you checked for blown fuses? Is your alarm professionally installed. Good aftermarket alarms have a limited lifetime warranty, with lifetime install warranty...

Let us know more....thanks

 

the alarm is factory came with the truck, the truck battery should be fine, ive got 12.59 volts dc on the battery. all my fuses are fine.
