Well, this saga is over. Mom found the key under a washer so there never was one stuck in the lock. Hate to think that her 88-YO mind may be slipping some. Thank you everyone for your insite and ideas and fingers crossed, I never have to use the tools purchased to attempt to remove a key.
I wuz just gonna say.....I ran into this years ago and managed to get the key out by putting Crazy Glue on an Exacto Knife, pushing the knife in with the glue side touching the key and waiting/praying. It came out. That trick also worked when I managed to jam a SIM card into a cell phone the wrong way.
So glad the problem was solved without a lot of problems. Something we all face is forgetfulness as we get older.
