I chose to have an old school key so maybe I should stay out of this, but I think if I had a keyless fob I�d be tempted to change the battery annually alongside the service for peace of mind.

When my original key fob battery first failed about three years after I purchased my RS, for about three months I received a wrench warning on my dash every time I started the bike. Unfortunately, I wasn't sure what the warning was about until I finally had trouble getting started and then it dawned on me what the wrench was trying to tell me. When I replaced the battery the wrench warning went away. So now I know to keep an eye out for random wrenches on my dash display and when I see one, I replace my key fob battery.

So my two week old new to me 2020 RS had the same warning come on when I brought it home. So I replaced the battery in the FOB. Now the warning still comes in every time I turn the ignition on. I assume I have to clear that through the OBX plug right?
Thanks

I don�t see why. It�s not an error code for the system�just an alert that it can�t detect the key. Where is the fob when you ride? It doesn�t take much to block the signal.

No need for OBX intervention. Perhaps your repacement battery is a duffer with little charge left. Try another one.

Ray,

Good call, I went and bought a couple of new batteries and installed one in the FOB and low and behold the warning is no longer coming up on the TFT...

Thanks for the tip. Another reason these forums are so good for all who visit them there is such a wealth of knowledge to be shared. I assumed the battery that I installed was good since it was new in the package. Good reason not to buy batteries in bulk. I suppose that one was sitting around in the fridge for many years (I keep the batteries in the garage fridge) somewhere I remember being told the fridge is a good place to store them. Don't really know if that is true or false or good or bad.

thanks again for the information
M.

This is a a data sheet for a typical CR2032 battery http://www.farnell.com/datasheets/1496885.pdf

Storage states 0-30C - a fridge is 5C typically.

poor quality control in the manufacturing is likely the most common factor in premature failure as long as you are buying in date stock
