I have used this forum several times and have gained knowledged that has saved me money. So I'd like to return the favor.

I recently purchased a 2002 Mercury Mountaineer. I wanted to program the keyless entry keypad but was without the factory code. The dealer will tell you that THEY need to download the code with THEIR diagnostic tool. This may cost anywhere from $20 to $70 depending on the dealership.

However, I found the location of the "little black box" that controls the keyless entry system. This "module" should have a small white sticker containing the 5 digit permanent factory code that is needed to program a new personalized code for the keyless entry system.

The "module" is located on the rear passenger side of the vehicle. It's behind and below the trim panel that has a cut-out for the upper adustable seat belt guide. You'll have to remove the aforementioned trim panel so that you can see the front side of the "module". You'll probably need a "mirror-on-a-stick" and a flashlight. It takes about 15 minutes.

If you're unsure of the location, sit in the backseat on the passenger side and use your key FOB to lock and unlock the doors. You'll hear a subtle clicking sound coming from the rear fender well. That's where the "module" is located.

Hope this information will be put to good use.

 

Where is it located on a 2010 Mountaineer ?
