The basic key remote on my 21 SR5 Tundra is giving out. Can the battery be replaced as I have never seen guts like the one in the current factory remote. Thanks

Yes, See video below. You will need a CR2032 Battery if your fob is seperate from the key. If the fob is part of the key, you will need a CR2016
