My friend has been charging his 992 GT3 Touring through the cigarette plug despite my admonitions to hard wire. Just called me to tell me the battery is dead, frunk locked, etc.
I read great threads here extensively on this about how to 'wake up' the battery. Just spent a few minutes searching and overwhelmed with the amount of posts about this in general.
Could someone help me out here with a quick link or the best way to either (a) wake the battery from the cigarette plug in footwell; or (b) get the frunk open so we can get it hardwired?

Would really appreciate the help.

Use metal key blade to open the door. Then need to jump the fuse box to get power to the car. Fuse box drivers footwell has a positive lead. Ground on door strut. Hit the trunk release button (can’t remember if it’s the one on the key or the one in the car) but one of them will open the frunk.
Thanks. I forgot there was a positive lead. Really helpful.
is the battery fried - or can they recharge?
Wondering if they should be ordering a new battery.
Every time I have read about this same condition here - the result always seems to be that the cigarette plug charger "shuts down" for various different reasons, the owner is not aware it has shutdown even though plugged in, so the battery goes dead. That doesn't happen with the hard wire solution.
GT3's have Rear Wheel Steering which means it also has the Li-Po battery. Most likely his battery is fine, it has gone into Deep Sleep mode.
1) Pull the Fuse Box Cover. Pull out the trunk fuse, its designed to do this (in the owner's manual). Then attach a 12v source to that fuse clamping on either side of it, grounding to the door hinge as Master Deep says. It's going to look like the red fuse in this (997) photo and may be in a different spot, but similar. See the hot leads on each side? Clamp there. Your trunk will now open with the switch.
2) Now you need a booster to "wake up" the battery. If you don't have one, this will more than do the job off Amazon and it will also power that fuse circuit to open the trunk....
3) Hook it up to the battery and then when ready, press the red exclamation point switch. Upon pressing the switch you will immediately hear the car come to life and it will start right up. Then, carry the booster pack in the car and you can always get yourself out of a jam.
Charging the vehicle with the Porsche supplied charger is a whole different topic and they don't work that well through the 12v plug in, its hit or miss. But the above will get the car going. If the battery is truly dead and does not wake up, its several months before replacements are available.
Do you need to use a booster to pop the frunk or would you be able to use a Ctek battery maintainer?
The CTEK can't do it. You need a booster and have to use the booster Max Power button to "wake up" the battery. There are a number of Booster products on the market, you can choose from a number of suppliers, the NOCO is one of the better ones.

Can the booster connected to the fuse box/hinge also be used to provide the 12v needed to pop the frunk?

There is a specific procedure that must be followed to prevent the cigarette plug charger from shutting down. Don’t recall off hand but it has been mentioned on several posts. Maybe someone will chime in.
