Find that key! Otherwise you'll have to go to the dealer to get it programmed and get a spare key ($$…) or do an immobilizer delete on the cluster. I have no experience with this, but you should get an idea of the process from the web.
If you had a working key (one that would start the car), the solution isn't as messy.

The spare (mechanics) key should work. Try leaving it in the on position for say 2 hours.

I once had immo problems what worked was disconnect both battery cables and strike them together to discharge any residual charge. Waited a little while connected the battery tried it again problem gone. Never came back either
