Key issues
 

So I let the mini sit for a few months, and when I went to the car, I used the fob to unlock the doors, that worked fine, but when I put the fob in the slot, nothing happens, no lights on the dash, and I put a new battery in the car and tried again and it still does nothing when I put it in the slot, is this an anti-theft issue? If so how do I fix it?
