2003 Tahoe FOBs coming unprogrammed

[Larrymjr]

Both FOBs intermittently come unprogrammed. Both have new batteries and still are coming unprogrammed. Does anyone have any ideas what may be the cause? Only thing I can think may have some influence on it in some weird way is that I also have a 2011 Silverado. I don't think so, but does anyone think my Silverado FOB may be doing something to unprogram my Tahoe FOBs?

Might want to try cleaning off the circuit boards on the fobs the opposite side of where the battery mounts and clean the rubber pad tabs that contact the circuit board .. also have the truck battery tested and or the battery circuit to the passenger door lock window switch thats where the fob reciver module is integrated with
