Key not detected in my Mustang – what could be the issue?
#1
So, I had this annoying problem today – my Mustang suddenly flashed the “key not detected” message on the dash while I was trying to start it. The weird thing is, the key fob was literally right in my hand, so it’s definitely not that I left it somewhere. First thing I did was change the batteries in the fob (you know, just in case), but that didn’t fix the issue.

I’m scratching my head here. Is this a common problem with Mustangs? I’ve read that sometimes the fob just loses connection with the car, but is there a way to reset it myself, or do I have to bite the bullet and take it to the dealer? I’ve also heard that there might be interference from other electronic devices, but I wasn’t carrying anything unusual.

Anyone have any tricks to get the car to recognize the key again? Should I be looking at the fob itself or could this be a deeper problem with the car’s receiver? Any advice would be super helpful before I go spend a fortune at the dealer!
