Keyless keypad stuck in lock only mode

[dandeliongo]

So I went to open my frunk with the keypad and the doors locked when I pressed 7, which happened to be the 4th digit in my code. So I thought I messed up and tried again. Googled it and found that if you enter the code too many times it goes into this mode. But only for 15min or by using the app to unlock the door. Didn't work.
Next it said to reset the pin. Which was a pain. Figured out how to program a new keyfob in the process. Nope didn't work.
Next was disconnecting the 12v battery, but I read that disconnecting the battery may cause other issues. So I did something that supposedly made the truck charge the 12v to 100% and was supposed reset everything like I disconnected it. DIDNT WORK!
So what happens when you disconnect the 12v battery? Explosion?
Any other suggestions?

There’s no downside to disconnecting the 12V battery.

Unless you count the hassle, are near flammable vapor, or like gremlins.

Not securing the connection properly afterwards is a concern with home mechanics. There is also this:

Note: Make sure the vehicle has been
switched off and doors closed for at least
five minutes before disconnecting the 12 volt
battery
