2018 Chevy Cruze Key Fob Issues

Both of my key fobs died for my 2018 Chevy Cruze, & I replaced the battery in one, but not the other (only had 1 battery at the time). The car requested to program the keys, & after programming the two keys I have, it asked for a third....which I was never given.

The start will work on the fob, but when pushing to start the engine once inside the car, it keeps asking to program a third key. What’s going on? What do I need to do to get my car to start??
