Hey guys, I installed a sub and am in car and not sure what that would have to do with this. But now my key fob wont open trunk, arm/lock car or unlock car. Pannic works, i can still start car and when I hit unlock it flashes lights like it did unlock but I am at a loss. I have checked every single fuse with multimeter and all are good.

Does anyone have a clue? I even did steps to reporgram function of fob according tomanual like unlock only drivers door or all 4 etc and still nothing.

 

Maybe try to replace the battery first and see?

 

thought about that but even the inside automatic unlock switch does not work. Is alarm intigrated into amp in rear of trunk???

 

what did you use as your 12V, ground, and remote?

 

For remote tapped into factory amps in truck as for ground used bolt on bracket by spare tire that was on drivers side
