Check your fuses. With Fuse #9 out or blown you cannot lock/unlock with the fob - but the console button will lock/unlock when in the car.

Check your dash lights with key in #1/On position. If most of the idiot lights are off -> check fuse #37 -- if this little 5A fuse blows your car will not start.
Also when fuse #37 blows your car will Start and then Stop --- the 3 tries and nothing symptom.

The fact that this car can turn into a paperweight over a 5A fuse.. blows my mind.
