Just received two new key fob shells off eBay and two new rechargeable batteries off Amazon.
Soldered new batteries into the old circuit boards and clipped them into the new shells.
Both key fobs working reliably again.
It sounds like a module failing somewhere but trial and error is a very expensive way to fix things. Do the lock/unlock buttons on the dash still work?
