You need to have the code that came for that vehicle. There are 2 places that you can look to find the code. Sometimes you can find a sticker in the back tailgate area it will be white and most of the time it is on the right (passengers) side. The other place you may be able to located is in under the hood most of the time it's on the drivers side firewall by the brake master cylinder. It will be a metal plate with 5 numbers on it like the sticker will have in the back if one is there. I hope this helps and good luck.

You can try holding the lock and unlock buttons near your car for 15 seconds as this works on some models
I'm hoping this works for you. You can call the service dept at the dealership and they should be able to tell you for sure free of charge.
Best wishes,

    Need location of 2006 mercury mariner security module to get keyless door pad code

    I have a 2006 Ford Explorer and I just found my keyless entry module. The module was behind the lower plastic panel on the passenger side rear panel right below the seat belt height adjuster. Not the panel with the seatbelt adjuster but the one below it. No tools were needed and it took me all of 5 minutes. Just pop off the front of the panel closest to the door and pull it back. Use a light and you can see the large 5 digit code on top of the module. Thanks very much to the people that contribute to this forum....Cheers
    This is really where it is!
