No idea how but I’m missing one world key and can’t unlock Dark ages.

It's a bug. Modern Day costs two World keys to open and players who decide to open the worlds in a different order than they are on the map will be one key short.
Contact EA Help and open a case "missing content" https://help.ea.com/en/
They should be able to sort things out.

This is an emerging issue. You are not alone. I have reported this issue to the support team and waiting from them to be fixed. No ETA yet.

@xianwahren Did you file it under missing content? They almost never reply to bug reports.

@1H3J0KER Yes, I did. I even send a screenshot of the game (showing no keys and unlocked journey) as a proof.

I'm having the same issue and have contacted EA about it and they said that there is nothing they can do.

They were not able to fix it because I think game keys are a part of the game code. So solving those issues will need a major rewrite of the game by making it a linear adventure mode like PvZ 1, and reprogramming your data.
Until something happens, my best advice would be to sync this account to your email, and start a new game on a different profile. I know this will be super-mega-ultra frustrating for you, but until EA fixes this issue, I can't really recommend anything.
Or else...
You could download Project Eclise (it's a modified PvZ 2 with major changes made to recreate the casual-gamer-friendly gameplay of PvZ 1 while incorporating the time travel theme). Although I haven't played it myself, I hear that many people are happy with it and compare it to the original non-pay2win, more balanced game. Don't worry, the graphics are exactly the same from PvZ 2.
Here's a link to their fandom page if you're interested.
