I believe that's probably a common approach (resynching the remote by using
the car key). At least it explains why the remotes (on our Exploder) once
in a while will suddenly cease to work, then they work are fine the next
morning--after appearing to need nothing more than a good night's rest. :)

But I wonder how does the system manage to keep _two_ remotes in synch with
the car? Seems that the remote gets synched to the car, not vice versa?
