Ignition Locked. I inserted a key from my other Subaru 2015 Crosstrek.

Dealer needs to program it to the keys that you have.

Look under the seat for any object that is jamming the seat rails.

The car has a brake light circuit powered transmission Park shifter lockout solenoid, so if the brake lights are not working when the pedal is pressed the car will not come out of park. Check the brake lights first. Also the owners manual should have a set of instructions to bypass the part lock, it varies with each car but some you turn the key to just short of the on position and wiggle the shifter while doing that, others there is a button hidden on the shift console

I, feel sorry for you, after reading your problem, but don't worry you visit the Reliable-Store they will help you for sure.

Not exactly sure if it has relay, but your fuse panel should be in the engine compartment and the blower motor Resistor, which controls the speeds of the motor, should be right by or screwed to the blower motor itself under the dash on the passenger side.

Yes that is normal, Subaru failed to tell customers of the oil consumption, if you go to your Subaru dealer they will fill oil to level & tell you to come back in 1200 miles time, they use 1quart every 1200 miles

Check owner's manual.

have you tried jerking the steering wheel to the left then right while attempting to turn your ignition key? that happend to me and thats all i did to free the ignition lock up, try it it might work.

You accidently tripped the anti theft deterrent that lock the whole ignition system when the worng key or a foriegn object is inserted into the slot. The only way to fix this, is to have it taken to a ford repair shop, since they will probably have to replace the whole steering collum.
