I was one of the first to start using the scheme and thought it fairly good, with the obvious exceptions of red locked bikes, full or empty stations and then no warning by email that St Pauls docking station was being locked out.
My Dongle no longer fits. It seems as though it has swollen just a fraction of a mm and when I attempt to insert it into the slot it just will not get any further than a few mm.s The Dongle now has a ‘scar’ on its top surface.
It is now going to take 3 days to receive a new dongle.
My advice is if you have had a key for more than a year and use it almost daily, check that its not beginning to come apart or expand. If it is then get it changed.
Mine has and I’ve just had a closer look to see if it would snap back, but it has now separated to reveal a transponder. It will not clip back into place, so I’ll try some super glue.
