How do you program the remote key-less entry for a 1995 grand marquis what is the perment code for this auto or where to find it?

open the trunk. there should be a sticker on the underside of it with the code on itmy 96 didnt have the sticker in the trunk anymore. It might be on a sticker inside your owners manuel. if not you will find it on a sticker inside the drivers door. you will have to remove your inside door panel a little to pry in back and look. that's where i found mine. you can confirm this by reading in your manuel if your car still has it.
