On our recent trips, we've noticed a possible glitch with our MagicBands. Until a MagicBand was used to open our villa door, it could not be used to open other locks around the resort, such as the door to the
DVC laundry room or pool gate. In May, I had three MagicBands and I used two of them to unlock our villa door. The third one I purposefully did not use on the door. I then went to the BLT laundry room and tried to use all three MagicBands to open the door. The first two worked fine, but the third did not. Later, after I used the third MagicBand to unlock our villa door, it worked fine on the laundry room door.
I've noticed this glitch at BLT and AKV, so I suspect it could be a system wide problem.
BTW, despite this glitch, I had no difficulty using my third MagicBand to charge things or to gain access to the Parks. The glitch seems to be limited to just locks around the resort, such as the laundry rooms and pool gates.
