Intermittent starting problem -2004 Porsche Boxster s

That's an interesting problem. When you say "flicker" are they flickering on and off, or just dimming a bit? My guess is that it's a problem with the voltage regulator on the alternator, or a problem with the alternator. Could also be a weak or bad battery, but I think you would have problems starting the car too. Check your fuse panel too to be sure they're all in there tight. If one is loose and rattling it could cause an issue like you describe.

Hello there

• There is a rocker switch on the left side of the foot well kind of by the fuse box on the drivers side.

• Hope this helps and thank you for using FixYa.

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.

do I need a a microship in my porsche key?

Try replacing the battery in the key. It may be too weak to engage lock.

Yes. It may have a weak magnet on it. Otherwise it would be the ignition or control module. Try replacing key first.

If the battery is VERY dead it may take quite a while jump start the car. You may have to run the car with the good battery for five or ten minutes to get enough charge in the old battery to start the car. Other wise a very dead battery will just "soak up" the electricity from the good battery. If your battery was old to begin with it may be unserviceable. I would take the battery out and take it to an auto parts store that can charge and test it. They will usually do this for free.
