Model 3 emergency opening of frunk when battery isn't dead

Hello. I have read that there are two conditions where you can use a 9 or 12 volt battery to open the frunk.

1. Dead 12 volt battery.
2. Car is unlocked.

I just tried it on my M3 with the car unlocked and it did not open the frunk. I opened the frunk from the touchscreen without any issue.

Is #2 no longer true or does my car have an issue?

Thanks!
 
It will indeed unlock the frunk with 12 volt battery source. The 9 volt battery did not work, but when I tried 8 AA batteries, it popped right open. I have seen multiple people say it would open with a 9 volt battery though. Thanks.
Tesla must have changed something that caused 9v not to work anymore. I do remember 1 or 2 people posting on a forum a while back saying that 9v didn't work anymore, but I didn't pay too much attention since I have a 12v battery (A23) stashed behind my tow hook cover and I know that works.

Your 12V is not dead if you can open the frunk from the screen...
