My 2013 Taurus Keyless Entry Door Pillar all of a sudden started flashing continually and will not stop. The first time it happened we didn't know about it and went to start the car and the battery was dead. I have tried to find a way to stop it. I tried to find the fuse for it and pull it. The only fuse I found to stop it has other electronic parts tied to it. My only option was to disconnect the negative battery cable. Has anyone else had this frustrating problem.
