Thanks BBF for the reply! Yes, there was no blade key inside of either FOB. I will take your advise and head to the dealer, I'm sure its not going to be cheap, but is definently needed. Only wish I checked the inside of the FOBs when I bought the car used. I was use to having the blade as part of the metal ring at the end of the FOB, so I figured it was like Mercedes and even Hyundai fobs. Still love my old 2013 MKZ!
