It has been a topic of recent discussion that we should be avoiding battery brands with a "bitterant" coating, or at least attempting to remove such coating with alcohol. The coating, applied to the negative side (bottom) of the battery would cause a voltage drop sufficient enough for the key fob battery to be seen as "dead." This also affected other electronics, especially Apple AirTags, of which over 55 million have sold. Apple began to recommend the same measures for their electronics.
Apparently, Duracell has rectified their design flaw, and is now advertising that they are compatible with AirTags, and as such, our key fobs. The coating is now applied to the positive side instead of the negative side, which will evidently solve the problem.
