I just bought an 03 windstar with keypad on the driver door. I am attempting to disable the autolock feature on the door locks. I have followed the manual instructions repeatedly with no success.
-Ignition switch to off position
-enter passcode on key pad
-press 3-4 button and hold
-press 7-8 button and hold
-release 3-4 button while still holding 7-8
-release 7-8 horn should chirp once to verify.
This procedure doesn't work and I'd like to know what I'm missing here.
