AITA for changing the door code after my mother-in-law used it at 6am?

our daughter is 7 weeks. my wife is recovering from a c-section that did not go smoothly. her mom has the code because she watched our dog while we were at the hospital. she has now used it four times without asking. the last time my wife was asleep on the couch with her shirt open feeding. i changed the code and texted her. that conversation is below. wife is somewhere between agreeing with me and not speaking to me.
What People Are Saying
the food is real and the gratitude is real and it still isn't a key. both things.
the one thing i'd change is it should have come from your wife. not because you're wrong, because it costs you less than it costs her.
that's fair and honestly it's the part i keep chewing on. i don't think she's malicious. i just needed it to stop today, not after a discussion.
Should I stay in my house, move downtown, or move near my daughter in Ohio?
my 7yo now demands a full salute before he'll eat his cereal, thoughts?
Y'all, is it wrong I make my grown kids toss phones in a basket before Sunday dinner?!
Should Bill and I go to our son's in Denver, our daughter's in Austin, or just stay put for Christma

"tell priya to call me, not you" is her telling you she plans to go around you. brace for that one.

i'm 62 and i'll say it, her generation genuinely was raised in houses where nobody knocked. she's not lying about that. she's just wrong about now.
