How do I get the door code to my 2006 Mercury mountaineer
Ask your local Ford dealer.
As far as I know it's not printed on the vehicle anywhere. Check your owner's manual. Maybe a previous owner wrote it down there. If not you'll need the vehicle registration and your driver's license for proof of ownership when you visit the Ford Dealer. They may be able to get it for you using the vehicle identification number (VIN). Hope that helps! Jim
