Key Card(s) Not Working to Unlock Car

This is weird. Happening with both key cards that I have.

Both keys are listed as active on the system. To test this, I tried to delete the second key card, and it asked me to tap the first key card on console and it worked. I was then able to add the second card again, tapping the first card on the console. But both key cards still won’t work to unlock the door.

The reason I noticed this is the app has been flakey lately. I’ve been having to take my phone out of my pocket to unlock, which I’ve never had to do before. So I tried the key card today, and it didnt work.

Tried a two button reset (twice) and a power off after the second reset. Key cards still won’t unlock the doors.

I also have a key fob, and that works. But, I usually use my phone as a key and the key card as a backup. My wife is the only one that uses the key fob.

Software is 2021.4.18.2

I‘m at my wits end. Can’t figure out whats happening.

Resolved!

My appt with Tesla mobile service was for tomorrow, but I got a call today from the service guy saying he saw some version mismatches in my firmware, so he pushed an update to my car. Interestingly, it’s the same version, 2021.4.18.2. I installed the update, and now the key cards work again. I’m a happy camper.

Thanks for circling back. I didnt respond to this thread at the beginning as I had zero clue what it could be (you tried all the troubleshooting I would have recommended). I was checking in on it because I was wondering what it might be. Thanks again for sharing the resolution.
