Door locked after power surge/failure

The question here is how long did you leave the breaker off? Gaggenau ovens have a memory and I always advise turn the oven off for 5 mins before turning the breaker back on. Give that a try. The first thing the oven does when the power is reapplied is go thru a test phase which included locking and unlocking the door. The key symbol will go on and off during this. Sometimes you have to also can run a self clean then cancel it to reset the lock. This works as well.

We did leave the breaker off for more than 5 minutes and did try the pyro clean mode letting it heat up and then canceling it. When the oven reached locking temperature it didn't self-lock nor did it unlock. The lock symbol is also not lit on the panel at any time... Thanks for the suggestions though!
