Modern Vespa

Hi guys,
Does anyone have any ideas about Liberty Immobilizer faults ? My scooter is less than two years old and it has a problem with the red light not going off. For example I went to work everything started fine but when I tried to start it at the end of the day the light stayed on and I was stranded.
It happened twice last week and is very frustrating . After an hour and a half roughly on both nights it started. I had to turn away a roadside recovery to my embarrassment .
It's now back at the dealership and they called and said there's nothing wrong with it only the battery is a little low . Any advice would be a plus
Cheers Lloyd

Which Key (blue, brown)? Original/spare?

It's both of the keys . I took the brown as back up but it did the same thing .

So it doesn't look like a problem with a key. Check Immobilizer LED codes

There is a ring behind the panel were the key goes in and it will fail without any warning. Sometimes the chip key gets noticed, other times you panic. I had mine go out while under warranty. I think Robot does a video on how to easily access the inside of the front panel. AF1Racing had the ring for sale for a fair price.

Thanks guys it's being looked at again this afternoon

Remove the key and try it again in the other direction (upside down or hole for key ring on the other side). I hope you understand what I mean. Alternatively, you can hold the second key very close to the lock.
