Key Unlocks/locks Door But Won't Start Car! Help!

[andx1]

Hey guys,

I've had my '06 is350 for 4 years now and have never encountered this problem. My car key unlocks/locks the door fine, interior lights and headlights/breaklights are working fine, but my key won't start the car. When I press the start/stop button, it doesn't go into accessory mode and absolutely nothing happens. I recently changed the battery on my key and I'm guessing that has something to do with it. This is really frustrating because I am sure it's not a battery problem because everything is working fine except my car is rejecting my key somehow(?) Please, if anyone could help I would greatly appreciate it.

Does your other key fob start the car?
