Keyless entry?

[Knmcc]

Hi, new poster here. I've been lurking for a while and finally decided to make a profile. I've just purchased my 2nd Explorer, a 2004 XLT nbx 4x4. The guy I bought it from said he had no problems using the keypad to lock the truck (7/8 and 9/0 together) but he didn't know the code to unlock it. So I looked up the tutorial on finding such code, and I found it behind the lower panel under the seat belt on the rear passenger side. But now that I've found that, I can't get it to work at all. Is it supposed to illuminate? My last ex didn't have this feature so I've got no experience with it. And I was wondering if maybe it could be a fuse? I looked all through the manual that came with it and I can't find a fuse for it on the map. Help please!

Could be the key pad itself. There are wires going through the drivers door that if broken (they do break), will render the keypad in-op. From the sounds of it, you have lost power to the key pad OR it is bad.

Thanks. After fiddling with it for some time yesterday I got it to light up, however I still can't get it to lock or unlock using a code. It does have aftermarket remote start, so I wonder if that has overrided the keypad somehow. Hmm..

Shouldn't. My bet is that there is a wire through the door loom, that is broken.

Welcome aboard!!

I had similar electrical issues with my '02 XLT. The dome lights would stay on until the battery saver feature turned them off, the accessory delay wasn't working, the driver side puddle light didn't work, the keypad on the door would set off the alarm when I pressed it, the door ajar light would flash and beep at highway speeds, the radio would shut off as soon as I turned the key off, the alarm would beep twice when I armed it. Recently all 4 windows stopped working. Most recently the driver door lock actuator stopped working.

A lot of electrical issues can be traced back to broken/damaged wire(s) in the boot between the body and the driver's door. I found 3 broken wires and repaired them. The thin black ground wire was broken and after repairing it all was back to normal. When the windows stopped working, I repaired the thick black ground wire and the windows now work like a champ. I had to repair the pink/black wire to fix the driver door lock actuator.

Here is a great thread for checking for broken/damaged wires, thanks to synyster for this awesome write-up: http://www.explorerforum.com/forums//showthread.php?t=270081

Unfortunately the pictures are no longer available in the above thread. IIRC, I believe I unwrapped the wires enough to gain access. When I have gone searching in there I had an idea of what wire I was looking for. I located the the wire I was looking for and gently tugged on that wire on the door side. The wire was pulled toward me and out of the harness. I then went inside the vehicle and gently tugged on the the wire I was looking for and was able to pull it inside the vehicle. I then spliced a length of wire to the 2 ends, completing the circuit. I then gently pulled the excess into the door.

Be sure to take your time when looking for broken/damaged wire(s). Check all the wires for breaks/damage. When you think you're done looking, look again, and again, and again. A bright flashlight can be very helpful.

Good luck getting it sorted.
