"Enhauto.com" supposed key card

I downloaded this app for my M3 and i tried using it, doesn't work and I don't want it to work anymore, i want to remove it but now I'm stuck with this stupid thing under locks > keys. It says unkown key enhauto.com, and to remove it I'm supposed to place it on the wireless charging pad.... but there's nothing to place so I cant remove it. Please help me this is driving me crazy!!!
