I have 38000 miles on a 2016 Pilot EX-L. I recently began getting a Keyless Start System Problem error message in the instrument cluster. I have tried both fobs and I have checked all of the fuses. Problem still persists. I tried disconnecting the battery for 10 minutes or so. The problem went away for about a day, but came back. Wondering what else to try before taking to the dealer. Thanks in advance.

Ridiculous excuse! This button should work for the life of the car. Max presses probably a fraction of what other pushbuttons get per day! We have push buttons in applications EVERYWHERE in our world. Think of television remote controls... these get pushed and abused and last for years! Elevators, microwaves, toasters, yada... yada...
The only thing that I find ridiculous is the price that some of these dealerships are charging for a 5 min job to replace a switch. Also if you take one of those switches apart, you will see that it is a very complex component and not just a simple pushbutton like you would see on other electronic devices. Cars today are getting way too complicated with gadgets and electronic components and as a result you are going to have more failures and I don't think it is just Hondas being affected so I am sure that if you check other auto forums you will see similar issues there too.

If the start/stop button is replaced do you have to have it reset with the fob?

If I put a new Start/stop button in does it have to be reprogramed with the fob?

I have a local mechanic wiling to replace button. Do you have to have the push button and fob reprogrammed?
I replaced mine with the genuine Honda part and there was no need to reprogram. All the functions including remote start and lock worked fine afterwards. I didn't even disconnect the battery as it is a quick connection plug on the back of the switch.
From what I can tell from other posts, no. But be sure to buy a Honda OEM part. Also I have only seen very few of these available in stock and local Honda dealer said they are back-ordered. You may still find on online at a Honda dealer.
I ordered one yesterday and will replace next week. I’ll post my experience.
Great news! Where do you find this? Can you send the link?

Now we just have to see if Honda Canada is on board too. It is suspicious that this was put off until a lot of owners had already replaced their buttons.
This is Honda Service bulletin 20-117 Issued December 9, 2020 “Warranty extension: 2016-17 Pilot and Ridgeline keyless start system error with DTC B1C5”
It will happen more frequently as time goes by so when it happens again, take it in to the dealer for warranty. You should have a B12C5 error code stored which will show when the car is scanned.
We started having the same problem with our 2017 Elite the other day, and I just read through this entire thread of 158 posts. You should have heard me happily yell out when 95% of the way through reading, several people posted about Honda's ESB a week ago to fix the problem! As always, thanks to everyone to contributes to these forums for all their help and advice.
Well Piloteers, success! The dealership covered the replacement on/off button! “Keyless start problem” error is now gone! Walk-away auto-lock now works!
....best part... free.
Thanks for all who have pushed and reported on this issue.
