Hello all, I just bought a 2004 Mercury Mountaineer and I have no idea what the code is for the keyless entry. Does anyone know where I can locate the code?
Thanks,
Jason

There is a barcode on an electrical unit under the dash, behind the brake pedal. You'll need a flashlight to see it. It usually is the last group of digits.

You'll want to pickup a new/used owners manual- it has programming instructions also.
