How do you get the hood open on a 2001 boxter with a dead battery?

One of two ways....either use a cigarette lighter car charger to give the car enough power to be able to use the switch or there is a red bar that can be hooked up to by another battery which will give you enough juice to use the switch located on the rocker panel by the drivers seat for the hood and truck release.

If you change out the battery make sure to keep the car powered from a secondary source. If you remove the battery without any power to the car you will lose the radio lock code and will have to take it to a Porsche dealership. There they will have to remove the battery (usually they charge for it) then send to SKU number from the radio to Porsche German Headquarters, who then emails the the code to the dealer (some dealers try to charge for that too but it is acutally free...only Ferrari and Maserati charge $50 for the radio code fee)
