98 was the year when they changed the synching I believe. Could be either way described. The other way is to do the 4 times trick which is, key in lock and holding the lock button, turn the key to lock then back to vertical, release button, press unlock and turn to unlock position, return to vertical and release button. Repeat four times and that should be it. We have a 97 and a 2000 model which do it DW's ways respectively and used to have a 1998 which did it the third way as I have described. Try all three.
