How do you unlock the drivers door on a 2000 Chevy Impala with a Slim Jim?

Call a locksmith. You don't use a slim jim on power lock doors. You have to wedge the top of the window open and hook the door handle with a long wire tool. If you break it, your insurance might not cover it and you're out the cost of a window. If the locksmith breaks it, insurance will usually cover it, either his or yours.
