Sorry for the delay. Glad it is working now, however; these are not able to be reprogrammed.
So, what I suspect happened is the battery is draining and you are most likely going to have issues again in the future.
If you do, then we need to try starting by replacing the battery in the key.
However, what I would suggest we do is program a second key just to be sure we can confirm this is the issue because if the other key works, then you know this key is most likely drained. Plus, it will give us a backup key, so you are not strained.
Here is a guide that will help others that visit this page on how to program a key fob just in case they don't have the same model year vehicle as you:

I attached the info below from the manual on how to add a key.
Please let us know but I am glad things worked out for you. Thanks
