This same situation just happened to me. I haven't driven my car in well over a month and I went out to my garage to move it so I could put some unused dressers behind my car but hold and behold, neither fob would open it. I knew it wasn't the batteries in the fobs given that both of them worked fine a little over a month ago and the likelihood of the batteries in BOTH fobs dying at the same time seemed slim to none. So I then tried to unlock the car the old fashion way but apparently something is wrong with the locking mechanism itself considering I could turn the key both directions but the car would not unlock. Who knows how long it's been like that - this is the first time in over 4 years of having the car that I have ever tried to unlock the car with the key itself. Going to try to unbolt the hood latch and see if I can get in that way. Wish me luck!
