Lock issue

[Grea]

Ok so i ordered up some new key fobs and programed them the way it says in the owners manual... And it worked.... But now the locks don't work right.... Sometimes all the doors will lock.. Sometimes just the driver door... Sometimes the two front doors... But not the two in back... Sometimes the lock button unlocks and the sometimes the unlock button locks... Just seems like i have to push a button and hope for the best.... I tried manually locking them all and then unlocking and locking that way... But no.. She just does what she wants to..... Minor irritation... But still irritating. Lol thanks in advance for any help or suggestions.

Try reprogramming them individually. Complete the process for one, then remove the key and test the fob. Then repeat again for the other. It's odd to get two defective fobs.
That said, have you ever had fobs prior? There could be a preexisting issue with the EX's system.

Welcome aboard!!

I have moved your thread into the Stock 3rd Gen Sub Forum.

I can send the troubleshhoting steps for the Door Locks from my shop manuals if you want.

Having said that:

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.
