Smart Key Battery Replacement The battery replacement video link has been removed from the Gen3 thread. Sorry for the inconvenience. It will be posted on Gen2 Maintenance thread.
This is posted in the wrong forum. The 2006 Prius is a Gen II, and this is a Gen III forum. The Gen III uses a different fob and battery, so this video does not apply. Tom
FYI--the Gen III fob is a different design. To replace the battery, you remove the metal key, and use it to pry open the case by inserting the tip into a slot at the top of the fob adjacent to where the key is stored.
