Keyless entry code not working after unplugging in 2004 explorer
While changing the window regulator on the driver side door of my 2004 Ford Explorer, I unplugged the keyless entry keypad so I could move the cable out of the way. I left it unplugged overnight and finished up in the morning. I plugged everything back in and reinstalled the trim pad. Since then the factory key code has not worked. I can still lock the doors by pressing the 7/8 & 9/0 or 3/4 & 7/8 buttons. All of the buttons appear to be working as they cause the keypad to light up when pressed. I have tried reset procedures posted online, but they all involve entering the factory key code first which is not working.
Is it possible that the factory key code was erased when the keypad was unplugged? If so is there any way of restoring it? I can't be the first person to unplug that.
