2006 envoy - wont start

My envoy started acting up a couple of days ago. It took about five minutes of cranking before it turned over and ran rough for a couple of minutes. After that it was fine until now. Now i tried to start it and it would crank but nothing and after a couple of minutes it would not even crank like the starter is not engaging i hear no clicking or anything. I took the battery in and had it tested and charged now when i put the key in i get the passlock symbol and wont allow me to do anything.

Welcome to AF. Leave the key on for 10 minutes to try and do a passlock relearn, then try and crank it over, now it is possible this is not related to the no start, because if the passlock were the problem it wouldn't crank.
