One of my key fobs failed recently, tried replacing the battery , a 1620, no dice. checked polarity, contacts, etc. still no luck. Is there something else obvious I'm missing? (I still have the 2nd one which works fine, so no biggie.) Would rather fix on my own than replacing it.

Thanks for looking.

(unrelated, but I read with alarm the "are the 2015s really that bad" thread--have just cleared 45000 mi with no issues and know other 2015 owners locally with no problems to report--dumb luck I guess)
