I don't know what is going with my armada's factory alarm? 2008 SE. When I hit the lock button it has no sound or beeping like before. It happens about 2 weeks already, only the linking light when I lock on alarm remote and no sound at all. Anyone have any idea.

Thanks

Hold down both the Lock and Unlock buttons on the remote for a few seconds and the horn beep will be back. Do the same to turn the beep off. That info is in your Owner's Manual.

It's working. just a little trick but sometimes you don't know

thanks

All the "tricks" is listed in the manual.
Like holding down the unlock button trick.:D
