Are you pushing the button on the key? Maybe the key battery is dead/low
And if you "jump" it does that supply power to anything else that would indicate power (ie radio, lights?)

Can the Porsche battery conditioner (the one that plugs into the lighter) get enough charge into a dead battery to open the hood?
(Never m ind... I tried it .... the answer is yes. After about 4 hours I was able to open the hood.)

i got the same problem
tried to pop the hood using a battery, but forget to put the key on the door, so it didn't work.
now i tried a few more times with the key on the door. no response at all.
note, i didn't lock my car, that's why it drained the battery. but the red alarm light was still blinking before i tried to pop the hood.
now the red light not blinking even i connect a fully charged battery through the fuse box. any thoughts? did the security system lock itself up?

The bolt that holds the air filter assembly (near the locking mechanism) is what I use for the ground, and there is a positive cable connection next to the power steering reservoir. If you look at your manual (for a '99) on page 144, you can see the box with the "+" on it. I have a 1 amp charger, so it took about 30 minutes to get enough power to open the hood.

Could somebody confirm that the reason for battery draining is that the doors were unlocked? If that really is the reason, what causes the battery to drain when the doors are not locked?

If the battery is dead the alarm still retains the alarm status but it does not function to sound an alarm. So it might be that after the battery gets up in charge the key needs to be cycled in the ignition to cancel the car being locked down since the battery went low enough to get the alarm to figure shut things down. I hope that's all it is. For the fob not working it might be the same case of the ignition needing cycling to wake the system up. After 5 days I believe the remote sensor for the alarm is shut down to save battery power. The owners manual says recharge every 2-3 weeks if not using the car and it also says every 3 months. One big thing it says is don't rapid charge the battery.

Porsche 996 C2-04) emergency cable trunk release
I left the key inside my Porsche 996 C-2 (04) and after few days the battery went dead, unable to start the car. I tried to follow the procedure in the manual to open the trunk (by connecting doner battery cable to the terminal in the fuse box etc.) without success. However I managed to open the trunk using emergency trunk release cable located inside the left tail light. The emergency release cable was stuff inside the tail light. I could see through the cable gap. I pulled it and the truck pop open.

OK, so my battery was 100% dead this morning (and for some reason my windows had rolled half way down). I've jumped it before so I know the procedure of connecting to the fuse box to be able to pop the engine hood, etc... I left the key in the door and everything, but the hood release still does nothing...???
As of 6 months ago my FOB doesn't work for remotely locking/unlocking the doors (got it wet). I wonder if that's part of the issue? Does anyone know if you need a working FOB in order for this to work?
Anyone know why the windows would have rolled half way down on their own?

The cable release is in the engine bay.
Yes, but with no way to get to it except by opening the engine lid!!!
Hood release is electric on my car.
The bolt that holds the air filter assembly (near the locking mechanism) is what I use for the ground, and there is a positive cable connection next to the power steering reservoir. If you look at your manual (for a '99) on page 144, you can see the box with the "+" on it. I have a 1 amp charger, so it took about 30 minutes to get enough power to open the hood.

Specific point, fuse, fuse outflow end?
I seem to remember you must remove a specific fuse and "jump", attach, to the fuse holder load side....
