2010 Concours 14 with about 32k miles, purchased around 20k miles. I think I'm the 3rd owner. The guy I bought it from at 20k miles gave me only one transponder. A couple days ago, I set it on the passenger seat as we were getting ready to go. I guess it slipped off to the left side and got stuck on the left saddlebag before my girl got on, then fell onto the road about a quarter-mile later and got run over. I found 7 pieces: front cover, rubber gasket, circuit board, battery, thin metal battery holder, main internal plastic plate, back plastic cover. The mechanical key was not in it at the time, it was in the saddlebag lock where it usually stays.
I was able to bend the plastic pieces back enough to get the entire thing back together. The circuit board appears undamaged. The battery shows signs of impact (small dents), but I was hoping to just use the passive feature for right now anyway. No luck so far. I have consulted the manual and I believe I understand the directions: remove mechanical key in transponder and place the resulting indent over the little nub right "above" the stove key. Hold there for 2 seconds, then I should be able to depress the stove key briefly and turn the key as usual. I also tried depressing the stove key for 2 seconds.
Ideally of course I'd like to have the transponder fully operational again (5 feet working range), but I thought the closer proximity feature would be more likely to still work if anything is still going to work, since it does not rely on a battery at all.
If neither of those goals are attainable, the 3rd-best solution would be to get a new transponder. But I guess an existing transponder or fob is needed to do that, or else an entire new ECU is needed (that would be the 4th-best solution).
Please let me know if you have any suggestions or expert knowledge that might help. I got the bike home but am dead in the water :/
p.s. I had never tried the close-proximity method before. I have had a couple low-battery messages but I replaced it quickly enough that it never died. So I can't be as confident that it ever worked/that I am doing it correctly now.
Oh and I'll try to get the pictures up here in a minute. Thank you in advance!
