Thank you in advance for any guidance you may have. I replaced the top cylinders on my car last night and inadvertently left the key in the ignition. When I went out this morning the driver window was down and the car is dead. I have tried opening the hood with the jumper in the fuse box following the procedure of opening the box, opening the car door lock, leaving the key in the door and attaching the jumper. I am using the door striker as my ground. I get a spark when I attach a batter charger but nothing on the car responds. I have tried using key fob, key in ignition. No response. Alarm does not sound. My aftermarket radio has a flashing light with or without the battery charger connected. Otherwise nothing in the car functions or responds. Your thoughts are appreciated.

Remove the battery connections. Put trickle charger on battery till 100%. Reconnect battery. Try again.

I would if I could but I can't get the hood to open. Nothing responds.

I thought all you had to do was connect the + of your charger to the bayonet in the fuse panel and the - to a good ground. No key position required to power the release mechanism

Double check your connections, and afterwards reroute the manual release cables to accessible locations.
There is a DIY for that here on the site.

I have checked and rechecked the connections to the bayonet. Trying to see if the 2002 has a cable to release good. Bentley shop manual says it doesn't.

I thought I read somewhere that some guys have gone in through the bottom of the engine bay to get some power. There is a (+) post just above and toward the passenger side of the airbox.

Are you trying to jump it to pop the hood using a trickle charger? How many amps it can provide? You need something like a real battery such as a booster pac to pop the hood. Try use jumper cables connected to a car battery of another car. Then connect the jumper cables to the fuse box jump point and door latch.

If you don't have another car, you can trickle charge your battery via the cigaretter lighter socket (with the right plug).

Ashai you solved it! I was using a 10 amp charger. Note enough amps. Borrowing jumper cables and using one of my other cars allowed the hood to open. Charger on it and I will replace the battery first chance.

Can you get enough juice to get into the engine bay?

ReidN

Sweet!

Don't go rushing out to get a new battery unless the one you have is 4 years old or more. Charge the one you have overnight.

Thank you all for the feedback. I believe the battery is over 4 years old so I will replace it as soon as I get a chance.
