Only time they are not on the bike is when I ride to a store and lock it, guessing the fob is away from the bike maybe once every 2 weeks. Point being, its almost always on the bike and Ive never had to replace the battery. Odd why some do, some don't.
Good luck

HD fobs have both a transmitter and receiver. The fob's receiver has a timer that wakes it up momentarily to see if the bike is nearby and polling it. This happens at a very low radio frequency of 125 kHz. If the fob hears this polling signal then it answers back with a coded identifier signal particular to your bike at 434 mHz. As you can imagine, if the fob is left within range of the bike it will constantly be consuming power as it continuously responds to the polling queries. Some fobs have a range of only a foot or two while others (like mine) will go 6 feet. This is why some folks can leave their fob in the saddlebag with no problems while others keep the key fob in their jacket but hung near the bike and still suffer dead batteries. For fob battery longevity, keep the fob well away from from your bike.

This is commonly believed, but erroneous. Leaving the fob in range does not result in constant communications draining the battery.

I keep my fob in the pocket of my riding jacket, which I toss over the handlebars when in the garage. Two years old, original batteries, no problems at all.
