I want to replace an outdoor security light for use at the driveway and
front door. Just one unit is needed in my layout.

This will replace one that has a mind of its own. It may come own when the
sun is still out though it is in a shaded location and it might not come
on at night even if I drive in, get out of the car and walk to the front
door.

All motion detectors have difficulty "seeing" motion when it is heading
directly _toward_ the sensor. They are very sensitive to motion _across_
their field of view, however. This may be part of your problem. Replacing
the sensor won't really fix this problem, motion detectors for alarm systems
have the same problem.
