Seeds will remain viable for several years, especially if they are stored away from moisture and light. I think your grass seed is just fine but if you want to test the germination rate you can sprinkle some seeds on a damp paper towel, fold the towel over them and set the towel in a plastic bag. Place the bag in a warm spot such as the top of your refrigerator or on a kitchen counter. Check the seeds in 6-7 days. If they've sprouted you can go ahead and use the seeds on your lawn. If they haven't sprouted, give them another week and check again. If still no sprouts, the seeds are no longer viable and should be tossed out.
