I have a 2002 porsche boxster and the dash light will not turn until I lock the door manually.

This is a problem with Porsche cars. What you need is a trickle charger or use the car on a more regular basis to keep the battery charged. If you have a garage with power get yourself a trickle charger and leave the battery on charge when not using the car. If this is not posible charge the battery up fully start the car and see if your dash lights go out. If they don't go off it might be your alternator is not working, get it checked out, or do it yourself if you can.

The battery on my 2000 Porsche Boxster is dead and the car is locked. How do I access the interior to release the hood?

The easiest way is to buy a cheap battery charger, one that plugs into your cigarette lighter socket. Allow the battery to charge for a few hours and then release the trunk when it has come up enough. The most likely reason for your battery going down is a faulty alternator. I just went through this problem with a friend. He bought a new battery and it went flat over night. He replaced the ignition switch (common problem), still went flat over night. Even though the alternator was charging great when the car was running, it was drawing current when the car was parked. We ended up getting a brand new alternator off ebay for $135., the dealer wanted $1900., local parts stores about $500.
The alternator was pretty easy to install and it solved the problem.

1998 porsche boxster, battery is dead on car, and

This is a common problem. Your alarm was on when the battery went dead. When the alarm activated, the hood/bonnet opening lever locks to prevent thieves from opening the hood in case the top is down. Some boxsters have a jumper post the pulls out near the fuse box. However, I do not think the 1997-1999s have this post.

Buy a male-to-male cigarette lighter adapter at the auto store. Connect between your car's cigarette lighter socket and the other car's cigarette lighter socket. Do not try to start the ignition or the any other electronics. You should not even need the key in the ignition. You should be able to pop the door locks with the remote and open the bonnet.

Replaced battery on 98 Porsche Boxster and now odometer is wrong

I had the same problem and was about to take the car to the dealership tomorrow, but I decided to try disconnecting the battery and see if it would reset itself. When I reconnected the battery the odometer mileage went back to where it was before I changed the battery. It worked!

Maybe it will work for you. Good luck!
