Hi , I’m looking for advice , last year my wife bought me a
2008 Cayman S
for my 65 birthday . I love it ! Problem is it got covered up for 3 months ( winter ) and now the battery is flat , I’ve tried connecting the red tab in the fuse board to other chargers just to get the bonnet open but no joy . Obviously the boot won’t open either so I can’t get the locking wheel nut out to enable me to remove the front wheel and inner wheel arch liner to access the manual release cable ! I stumped ! Has anyone got any ideas what I do
next
? TIA
Try an alternate power source to the jump post than what you used? Pretty sure my NOCO will deliver power to it, they aren't that expensive and

year it would keep you out of trouble. One also has to make sure those connections are well established; I've read that on here before. If that was what you used or equivalent, try another car battery like a jump start situation. Others have had success with charging through the cigarette lighter port if your car is so equipped.
As Boris noted - sometimes a battery is better than the jumpstart packs. I have a jumpstart pack that won't output any voltage if it doesn't see any voltage on the connection to the car. Many are like that (it's to prevent people from shorting the two connectors together when a car isn't connected and blowing up the jump pack due to excessive current draw.. Some of them have a switch to override that lockout (mine doesn't AFAIK..)
I do keep an old motorcycle battery on a smart charger around the clock in my garage, just for that reason. It works when the jump pack won't.

Plug a 12VDC source into the cigarette lighter socket (from a battery) it will allow you to use the switch to open the bonnet
I keep a cigarette lighter adapter in the glovebox for this situation. Would be wise to keep the wheel lock key in there too vs elsewhere
Once you get fixed.... keep it on a charger if not driven for over 4-5 days..... mine is now 10 years old as of this Oct with still over 80 % charge. Garaging helps. These banner batteries are good if taken care of.
