My 2004 RK process requires the key fob button be pressed TWICE after each and every digit change/command. Obviously, that would indicate recognition by the system.

 

Dang - I am getting old. After the conversation yesterday, I was going to try exactly that, since it still bothered me that I could change that code. That's what I was originally trying to do when I mentioned that I changed the code last night, but I realize now that I did in fact have the fob in my jacket.

I didn't ride today (hockey game and beer after work), but I can check on this tomorrow at lunch or something. Thanks for keeping my head straight, and for sure I'll post what I find.

 

Yep on the older FOBs you had to press the button in the center of the FOB, the newer FOBs (I think 07 and up) do not have a button on the FOB. As soon as the FOB is a certain distance away from the bike the system automatically arms. On those to change the code no button press on the FOB is needed you just have to have the FOB close to the bike.

 

Interested in seeing what you find out

 

Thanks for providing that info. I didn't know they omitted buttons after '07..

 

Without an "Active" FOB present, you can NOT change the security PIN.

 

I understand that and that is the mystery here. If you read the thread you will see that the OP had an issue where his bike was not recognizing his FOB and would not allow him to start the bike, so he used his PIN to over ride and start the bike. He has since replaced FOB battery and checked to make sure it was not installed upside down but his FOB is still not recognized by the bike and will not allow it to start without him using the PIN to override

However despite the fact that the FOB is not allowing him to start the bike (Fob is not being recognized by bike) he is able to change the PIN and has done so twice. He should not be able to change the PIN due to the fact that the FOB is not being recognized if the system is working correctly.

Each time he changed the PIN he did have the "non working" FOB in his pocket, so as an experiment I asked him to try changing the PIN with out the FOB nearby. If he is still able to change the PIN then something is wrong with the system, other than just a bad FOB. If he is not able to change it without the FOB present then that would mean that the bike is recognizing the FOB as he did change PIN with it present but for whatever reason it wont allow him to start the bike

BTW you have good taste in bike colors LOL

 

My guess is, he is having intermittent issues with the FOB.
At the time he is changing the PIN, the FOB is working (even if intermittently).

The mystery is what is causing that issue.
Could be something with interference in his pocket (cell phones have been know to cause some issues).
Could be the contacts in the FOB, or a flaky battery.
Could be the security module itself being flaky.

He is not changing the PIN without a active working FOB present.

 

I agree. Since boths fobs stopped working properly at the same time logic seems to dictate that the problem lies in the bike somewhere rather than in the fobs.
I don't have security on my bike so cannot give specific help. But I would follow up on the antenna suggestion. I'd also check all wiring connections to and from the module, since the problem cropped up after a battery change perhaps wires were tugged and a connector loosened.

 

So, for those interested, this isn't going to end in the discovery of some crazy unique problem. After a two day rain (and tornado) delay, I've spent the last two days riding. On Saturday, I opened things up under the seat. I have quite a few wires running around in there, and I spent some time labeling them. I found the antenna and checked along the cable, and all seemed well. Disappointed at not finding something obvious, I put everything back together. When I looked down, I noticed that the system was disarmed. Sure enough, she fired up without problems. I walked away and back, and saw it arm and disarm (for the first time in weeks). I repeated that with the other fob as well.

While I was under the seat, I didn't pull any wiring, it was more re-arranging. I'm guessing that a wire was either crimped (less likely in modern electronics, I'd think), or maybe there's a short (more likely, and more concerning). With about 600 new miles, and ~10 starts and stops, I have not seen a repeat of the original problem. In my mind, that doesn't mean it is completely resolved, but maybe the wires are living happy enough after the re-arranging.

Now I'm working of two assumptions here. The first, is that if this is a short, then it's possible during riding things had shifted and that's how I was able to change the code before. It seems like a stretch, but I cannot come up with a better theory. I did try putting my fobs in my house, and I was unable to change the override code (which is good). The second assumption is that I am good until my next service, which is coming soon. I haven't had a problem actually riding the bike before and since the problem went away. The override code entry still works, so I'm guessing that things will be ok until I take it in.

Thanks guys, for all the suggestions. If it pops back up or the dealer finds something, I'll come back here.
