My used 2015 GT came with one FOB, so I had the dealer program an additional one for me. When I picked up the car from the dealer and started it, the check engine light was on. I pulled it back around to the service door and the technician worked on it. He ultimately said that the instructions for programming a new FOB didn't mention that they needed to reset the engine codes that may come up as a result of the programming process. He took care of that for me.
I used the new FOB the next day just fine, but at the end of the day when trying to start the car I got an error saying "Key FOB not detected" and the car wouldn't start. Fortunately I was at home, so I grabbed my original FOB and it worked just fine.
I brought both FOBs with me to work today so I could have the dealer look into it. During my drive to work I heard my door locks clicking several times by themselves, and while at work I noticed out my office window that my tail lights would come on and off every few seconds, as if the car was locking/unlocking itself.
I returned to the dealer, and after some research they determined that the new FOB had the wrong batteries in it. The batteries were too strong, causing intermittent problems.
Just thought I would pass this along in case any of you experience these FOB gremlins.
