Hi - 
I had an aftermarket remote starter installed in my 2011 Ford Edge SEL (by a local shop in town).  For the first month or so it worked fine, but has recently started to cause a problem -- whereby shortly after you use the remote start (within the next day or so) both factory key fobs stop working completely (lock/unlock/etc.).  NOTE: the remote starter that was installed is activated using the factory key fobs as well.  If I pull the fuse for the anti-theft system and let it re-set itself (and re-insert the same fuse), everything works fine again for another day or so.  Or, if I pull the fuse, re-insert it, and don't use the remote starter at all, the fobs continue to work fine indefinitely.  Has anyone seen something like this before ?  And is there anything I can try other than having the aftermarket remote starter removed completely ?  Any help/suggestions would be most appreciated !
