Key FOB battery run down?
So, my bike was parked in my garage and I hung my key FOB on the clutch lever. A week went by and when I went to start it - the speedo display said low battery key fob (or something close to that).
My question - Does keeping your key in close proximity to your bike cause the battery to run down? Bike is a 2018 Classic.

I just had to replace the battery on mine (also a 2018). Don't know how long the battery is supposed to last, but mine made it two years, so maybe it's just time.
And no I don't keep the fob near the bike, I keep it indoors.

I hang my fob on the handle bars all your long no problems. I always carry a extra battery just in case. And the answer to your question how do you know when the battery is going dead. WHEN YOUR BIKE WONT START

I would think close proximity constant signal = battery use
My first FOB, it's in my pocket or in the house. No, you dont get to know where in the house

I would think it would affect the bike's battery more than the FOB's. As far as I know, the FOB just transmits constantly regardless of bike proximity. But there are circuits on the bike that turn on when the FOB is nearby.

I can't find the thread, but a member posted a link to HD's application to the FCC explaining how the system works.
Every few seconds an armed bike emits a RF signal. If an assigned fob is within range, the fob wakes up, and emits a RF signal to disarm the bike. This back and forth RF communication continues every few seconds while the fob is within range. If the fob is out of range, and never awakened by the bike's RF signal, the fob's battery is not being used. I would presume the battery in a dormant, out of range fob would outlast the battery in a fob that is emitting a RF signal every few seconds.
