The car was not used for 6 months.The battery inside is flat.The key doesn't even work mechanically and can not open the hood to change the battery insde the car.
Any suggestions?

 

Welcome to the forum. You have posted your question in the "Forum Issues" section. As it says, it's for people who are having issues with the forum, not for people having issues with their cars. For issues with a Pacifica, you should post up in the Pacifica section.

Beyond that, your question is not at all clear. Are you saying that you cannot open the door to get in the car? If not, how do you know the battery is dead? If you can open the door, why can't you pop the hood? If the key won't turn at all in the ignition, try putting a little bit of WD-40 on the key, put it in the lock and wiggle it in and out while trying to turn it. Be persistent but not forceful. Are you sure you have the correct key?

 

Ohhh...thank you. Didn't see I was in the wrong section.
Thank you for your prompt reply.
Will post my question there and try to be more clear.
