Narrative:

At the gate in sfo; fix KD45S was entered as an en route point instead of KD42S. ZDV said 'we show you a little off course.' we corrected on course. No conflict with other aircraft. The fix just prior to KD42S was a KD45 fix as well. I remember checking the route at the gate. My mistake; I need to be more diligent and really look at what I am checking.
