FWIW, there apparently still are sources for "spare" plastic car keys. AAA is also supposed to have made them for members, in some offices on request. Of course a plastic key won't have the security chip so it won't engage the starter and might not disengage the security system...but it would get you inside the car, where a real key might be carefully stashed. Not a big help for a rental car, but something worth looking into for your own.
