Electronics » Keyless petrol cap not opening.

Hi guys, got to the petrol station, switched of the ignition, lifted the tab on the filler cap and cap won't open, tab lifts but cap doesn't pop up. Keyless bike.

Sure I read about this on the forum but search has only got someone's that won't close.

So anyone had this happen and how did you sort it out?
Cheers

That would happen sometimes on my wife's R1200RS and happened at least once on my bike. You probably know if you waited too long to open the cap it will timeout and you need to lift the tap a 2nd time.

Most of the time when it was really stuck, repeatably lifting and lowering the tab will get it open.
Debbie said it was best to slowly lift and listen or feel the click.
If that doesn't work you need to remove the two torx screws and remove the small part of the gas cap ring.

How close was the fob to the bike’s antenna or fuel cap? I’ve had this happen, and it goes away by holding the fob close to the gas cap.

Thank you for the information. Being able to disassemble the filler cap was and important step.

After getting the filler cap released, by dissembling, I could see/hear that there was nothing happening at the filler lock, no noises. So I also took off all the bodywork from the tank. Trace the wire from the lock down to the inside of the left side fairing frame rail and found a corroded break in the wire, nearly 48,000miles of wind had obviously flexed it enough to break the insulation and let salt and grime in and has eventually failed.

I’ve soldered in a new connector.

This has improved the situation, I can now open the filler, but not cured it fully. When I switch off the bike, when I'd normally be able, for 90 seconds or so, to pull the tab and release the filler cap, that still isn’t happening; unless within the 90 seconds, I disconnect the power to the lock mechanism and reconnect it, i.e. disconnect/reconnect the new connector I’ve installed, then I hear the click at the petrol cap and can lift the tab and open the filler cap.

If I then close the filler cap I can’t re-open it, unless I disconnect and reconnect the power (with in the 90 seconds), very odd. I have disconnected the bike battery for a few minutes to see if this would reset something, but hasn't.

I can live with this for now, a second had keyless filler cap is £125, and there's no guarantee it is the 'failed' part.

Again thanks to all, but especially Lee for the photos, a massive help.

Had this happen to me on my 2016 1200RS; of course it happened on a cold, rainy evening 200 miles from home...
It did eventually open on the forecourt and I was able to get the bike home. It generated a fault code on my diagnostic tester and fortunately the incident happened just before the warranty expired, so the several-hundred-££ was done under warranty. Confirmed all my fears and prejudices against keyless bikes, though.

This has happened to all my RS's.
I have cured mine by lubercating the silver part with the slot and small pin in it half way between the two torx bolts in the picture. I ride my bike the whole year round and corrosion makes this part stiff.

Okay so I did a couple rides and used the connector to un-power and re-power the keyless lock so I could open it and fuel. However I've soon started to worry that the actual electronic lock mechanism may fail completely, whicle I usually have enough tools with me to open it I decided this wasn't sustainable, I started looking around at options. Second-hand electronic lock over £140, no guarantee it wouldn't fail as well.

Eventually I've gone to Motor Works and bought a second-hand keyed filler assembly and a lock re-coding kit (total of approx. £100) and I have fitted this instead.

So to complete this topic, I decide to also get myself a second metal key (without a transponder) so I could keep the transpondered key in a waterproof pocket and the new one in a more accessible place to remain gloves on for fuel stops at a pay at pump.

I contacted this guy (after getting the details from Wessie, thank you) https://www.keysinthepost.com/ - I tried his web page contact first and after a week of no response gave him a call. Apparently there is a problem trying to contact him via the web site. No problem he was really helpful on the phone and after explaining what I wanted and sending him a photo of the key blade via WhatsApp, he quote £15 delivered, took payment over the phone - and the key was delivered within 72 hours. Key opens the petrol cap, seat and the panniers as expected. :-)

You mentioned remaining "gloves on" at a fuel stop. Presumably this is so you don't have to handle the pump with a bare hand, which then goes back into your glove. If that's correct, there's another solution that I've used from Day 1. I take a paper towel from the dispenser next to the windshield-washer squeegee, wrap it around the pump handle, pump my gas, then dispose of the towel. My hand never touches the pump handle. I've seen others do this, too, including some on motovlog videos.
