My 07 crew cab this morning would not respond to my key fob for about 15
minutes. Thinking it might be the Fob battery, does not look like easy
access...don't want to destroy the $$ thing. Anybody had success, will it
require reprograming of one or both??

Not likely the battery. My 99 still has it's original batteries and works
flawlessly.

I changed the battery in my '03 very easy and it did not require
reprogramming. There is a slot on the edge near the key ring, just stick a
dime in it and twist and it will pop apart. The battery shouldn't go dead
that quick. Mine lasted about 5 years average use about once or twice a
day.

I will read my OM tonight, but do not think so, never came across that
whilst twiddling the settings for other things.

I agree, battery should not crap out this fast, so I am now carrying both
FOB's and when/if it happens again, should be able to make an educated guess
on whether or not it is a FF (Fob Fart). Googled FOB battery replacement
and got varied answers for GM vehicles themselves, some people say 5 yrs is
normal, others it has to be reprogramed etc. Wifes 2003 works without
incident. As far as opening it, my FOB does not have a slot near the key
ring, a dime is to thick to fit in the "crack" to open it. I was always
amazed at how far away you can be and still have it do lock/unlock or remote
start. Ebay list the part number as GM/O: 15913421 4 button remote,
